Description

The invention relates to a bearing according to the preamble of claim 1, as well as a use of the bearing for fixing it to a shaft and a use of the bearing for releasing at least a part of the bearing from a shaft. A bearing of this type comprises a bearing housing and a bearing core arranged within the housing. In a standard operating condition, the housing typically surrounds the bearing core around a bearing axis, thus holding the core in a defined radial position relative to the housing. A standard operating condition is defined as a condition in which the bearing is configured to absorb static or dynamic forces from a stationary or rotating shaft passing through it. The bearing core has a radial outer surface which, in a standard operating condition, bears at least partially, and in particular completely, against a corresponding inner surface of the housing.In the operating state of the bearing, the bearing core and bearing housing interlock along the bearing axis in such a way that the bearing core is positioned in a defined radial and axial position relative to the bearing housing, whereby, in particular, the inner surface of the bearing housing and the outer surface of the bearing core can interlock. Specifically, the bearing core can be fixed by the bearing housing in a radial and / or axial position relative to the bearing housing, or its position relative to the bearing housing can be fixed in such a way that, starting from the operating state of the bearing in which it is positioned in a defined radial and axial position relative to the bearing housing, it cannot perform any translational movement in the radial and / or axial direction relative to the housing, but at most a rotational movement. The terms "axial" and "axial direction" denote a direction parallel to the bearing axis, while the terms "radial" and "axial direction" denote a direction parallel to the bearing axis."Radial direction" describes all directions in a plane perpendicular to the bearing axis. The bearing axis is uniquely defined with reference to the bearing core. When referring to the bearing axis for the definitions of other bearing components, and when the bearing core is rotatable relative to the bearing housing about an axis of rotation perpendicular to the bearing axis, the reference is made by defining a rotation angle of 0° about the axis of rotation. Furthermore, the bearing core has a receptacle designed to receive a shaft. The receptacle is designed as a passage extending through the bearing core along a bearing axis, such that a shaft can be inserted axially into the passage in such a way that it extends through the passage and beyond the bearing core on both axial sides.The bearing core has, in particular, an inner surface facing away from its outer surface, which at least partially limits the passage. The bearing housing comprises at least one first housing part and at least one second housing part. In an operating state of the bearing, the first and second housing parts are arranged in an operating position relative to each other. Furthermore, the bearing has a fixing device by which the first and second housing parts are detachably fixed relative to each other in their operating positions. Due to the multi-part design of the bearing housing and the detachable fixing of the housing parts by means of the fixing device, the bearing housing can be disassembled to allow access to the bearing core for maintenance purposes, for example, to replace or repair it. However, the maintenance or replacement of the bearing core in conventional bearings presents several difficulties. The multiple housing parts intended for maintenance must be reliably and robustly fixed to one another in the operating position, while simultaneously ensuring the simplest possible assembly and disassembly of these parts. Furthermore, the maintenance process—specifically, the simple sequence of disassembling the housing parts, replacing the bearing core, and then reassembling the housing parts—should ideally be achievable by a single person. Conventional bearings inadequately meet these diverse requirements. The present invention is therefore based on the objective of providing a bearing or a use of the bearing for fixing to a shaft or a use of the bearing for releasing at least a part of the bearing from a shaft, with which at least one disadvantage of generic bearings or uses is at least partially eliminated. As a solution to the problem underlying the present invention, the invention proposes a bearing with the features according to claim 1. The bearing comprises a bearing housing and a bearing core arranged in the bearing housing. The bearing core has a receptacle designed as a through-passage extending through the bearing core and along a bearing axis of the bearing. Furthermore, the bearing core has a radial outer surface with which, in an operating state of the bearing, it bears at least partially against a corresponding inner surface of the bearing housing. The inner surface of the bearing housing and the outer surface of the bearing core interlock radially and axially in the operating state of the bearing, such that a radial and axial position of the bearing core relative to the bearing housing is defined.In this way, the bearing core, apart from any possible play, for example due to tolerance deviations, is held radially and / or axially fixed relative to the bearing housing and can thus perform translational movement in the axial or radial direction relative to the bearing housing. The interlocking of the inner surface of the bearing housing and the outer surface of the bearing core can be achieved, for example, by providing corresponding projections and recesses and / or by a spherical design of the outer surface of the bearing core and a spherical design of the inner surface of the bearing housing corresponding to the spherical outer surface of the bearing core. Preferably, the bearing housing surrounds the bearing core at least partially, preferably completely, both axially and radially. The bearing housing comprises at least a first housing part and at least a second housing part.In principle, it is conceivable that the bearing housing could have more than two housing parts. However, it is preferred that the bearing housing has exactly two housing parts, namely the first and the second housing part. Such a limited number of housing parts simplifies the assembly and disassembly of the bearing. In an operating state of the bearing, the first housing part and the second housing part are arranged in an operating position relative to each other, with a fixing device provided by means of which the first housing part and the second housing part are detachably fixed relative to each other in the operating position. Because the fixing device is designed to detachably fix the housing parts relative to each other, the bearing can be converted from its operating state to a disassembly state when the fixing device is actuated. This means, in particular, that actuating the fixing device releases any connection between the first and second housing parts that is formed by a fixation present in at least one section of the housing parts during operation. "Fixed" means that the first and second housing parts are arranged in a positionally fixed relative to each other. The housing parts are only movable from their operating position relative to each other when the fixing mechanism is released by actuating the fixing device, thereby dissolving the bearing's operating state and transferring it to the disassembly state. Upon release of the fixing mechanism, the first and second housing parts are movable relative to each other in the disassembly state. "Releasable" means, in particular, that the fixing mechanism can be released non-destructively, with "non-destructively" referring to the fixing device and the bearing housing as well as all other elements of the bearing according to the invention. After the bearing has been transferred from the operating state to the disassembly state, the first and second housing parts are arranged in a disassembly position relative to each other, which may, in particular, essentially correspond to the operating position.This is the case, for example, when the housing parts remain stationary when the locking device is actuated, but the locking mechanism is released as described, so that they are movable relative to each other after the locking device is actuated as described, in particular from the disassembly position. Advantageously, the first housing part and the second housing part can be arranged in several further disassembly positions relative to each other. Furthermore, the bearing has a holding device. The first housing part and the second housing part are held together by the holding device when the bearing is disassembled. Preferably, the housing parts are also held together by the holding device, at least in part, when the bearing is in operation. Preferably, the fixing device includes the holding device, wherein, in the operating state, the housing parts are fixed together by the holding device and at least one further means or component of the fixing device, whereas in at least one disassembly position they occupy relative to each other when disassembled, they are fixed together only by the holding device. Preferably, the holding device contributes to ensuring that the housing parts are fixed in their relative positions when the bearing is in operation.In particular, the first housing part and the second housing part are connected to each other in at least one section by the retaining means in the operating state and / or in the disassembly state of the bearing. The first housing part and the second housing part are held together by the retaining means in such a way that they are movable relative to each other in the disassembly state. Preferably, the retaining means is designed such that the first housing part and / or the second housing part has at least one degree of freedom, preferably exactly one degree of freedom, relative to the other housing part in the disassembly state. However, it is also conceivable that the first housing part and / or the second housing part has several degrees of freedom relative to the other housing part in the disassembly state. Because the first housing part and the second housing part are held together by the retaining means in the disassembly state, the loss of one of the two housing parts can be avoided.In particularly advantageous embodiments, the retaining device ensures that the housing parts are aligned relative to each other in a defined manner, both in the operating state and in the disassembly state, as well as during the transition between the two. For example, during bearing maintenance, one housing part can remain attached to the device with which the bearing is used, so that the other housing part also remains attached to the device. By simultaneously ensuring that the housing parts are movable relative to each other, they can also be separated from each other, at least section by section, to allow sufficient access to the bearing core for its repair and / or replacement. In one embodiment, the holding means is designed to guide the first housing part and / or the second housing part along a path from the disassembly position to at least one further disassembly position when the bearing is disassembled. In this further disassembly position, the housing parts are spaced further apart from each other, at least in sections, than in the disassembly position. In particular, the holding means is designed to define a further disassembly position in which the housing parts are spaced as far apart from each other as possible, at least in sections. Preferably, the holding means is designed to guide the first housing part and / or the second housing part along a defined path. This means, in particular, that the holding means provides guidance for the first and / or second housing part.In particular, the guide restricts the movement of the housing parts relative to each other in at least one degree of freedom, so that the housing parts can be guided from the disassembly position to the next disassembly position along one or more defined directions of movement and / or rotation. Specifically, the guide defines a beginning and an end of the path and thus a distance along which the housing parts can move relative to each other in the disassembly state. The guide can thus generally restrict the movement of the housing parts relative to each other in the disassembled state. In particular, the path of the housing parts is mechanically defined by the holding device, whereby the first housing part can have a first guide element and the second housing part a second guide element, which interlock in such a way that they provide a defined path for the movement of the housing parts relative to each other. Advantageously, the housing parts are guided along the same defined path during each guiding operation from the disassembly position to at least one further disassembly position, and vice versa. This has the advantage that a person servicing the bearing always knows exactly where the corresponding housing part is located. Advantageously, the path can also be defined in such a way that the risk of damage to the bearing housing during maintenance is reduced. In one embodiment, the movement of the first and second housing parts relative to each other is restricted by holding them together by the retaining means such that at least one of the first or second housing parts is displaceable and / or rotatable relative to the other of the first or second housing part when the bearing is disassembled. In particular, the housing parts can be displaceable axially or radially relative to each other. A linear guide can be formed on the first or second housing part, against which the other of the first or second housing part engages, thus enabling displaceability. Preferably, however, the first and second housing parts are rotatable relative to each other, and preferably, the housing parts are rotatable about the bearing axis. Preferably, the housing parts are rotatable but not axially translationally movable relative to each other.In particular, the holding means in one embodiment includes a bearing, preferably designed as a rotary bearing or pivot joint. A rotary bearing or pivot joint enables a cost-effective implementation of the bearing according to the invention, while maintenance allows for controlled and straightforward relative movement of the housing parts to one another. In one embodiment, the rotary bearing or pivot joint can be formed by the first housing part or the second housing part having an axially extending pin that is at least partially engaged by a hook-shaped element arranged on the other of the first or second housing part, in particular by the pin engaging in a corresponding axially extending receptacle of the hook-shaped element.Preferably, the pin can be fixedly attached to the first or second housing part, wherein the housing parts are rotatable relative to each other by means of a rotatable connection between the pin and the hook-shaped element. However, it is equally conceivable that the hook-shaped element rigidly engages the pin and rotation is enabled by a rotatable bearing of the pin on the first or second housing part. In particular, in this case, the pin and the hook-shaped element can be formed in one piece. In one embodiment, the holding means and the fixing device engage at least partially on the same first housing section of the bearing housing extending along the bearing axis, or the holding means is encompassed by the fixing device and thus forms part of the fixing device. Preferably, the fixing device comprises at least one further component in addition to the holding means. Additionally or alternatively, the holding means and the fixing device engage on the same second housing section of the bearing housing extending in a plane perpendicular to the bearing axis. For this purpose, the bearing housing is preferably elongated along the bearing axis, and in particular, the bearing housing is hollow and cylindrical. Regardless of the shape of the bearing housing, this has the advantage that the holding means and the fixing device, respectively, engage on the bearing housing.at least one other component of the fixing device can work together to fix the housing parts in the operating position in a releasable manner relative to each other. Furthermore, the invention proposes, as a further solution to the problem underlying the present invention, a bearing with the features according to claim 7. The bearing has all the features of the preamble of the bearing according to claim 1. In addition, the bearing may have one or all of the other features described herein in relation to the solution introduced above. Generally preferably, the embodiments of the various solutions described herein may advantageously have features that are described in connection with embodiments of other solutions. The fixing device of the bearing according to claim 7 comprises at least one locking means that can be actuated without tools. By means of the locking means, the first housing part and the second housing part can be fixed relative to each other in their operating position without tools, thus realizing the operating state in which the housing parts are fixed relative to each other. In particular, the fixing device comprises the locking means and the holding means, wherein the housing parts are fixed in their relative position to each other in the operating state by the interaction of the locking means and the holding means. Additionally or alternatively, the first housing part and the second housing part can be separated from each other, at least partially, without tools, to transfer the bearing from the operating state to the disassembly state, so that, in particular, the fixing of the housing parts relative to each other can be released without tools.For example, in the disassembled state, a section of the first housing part can be detached from a section of the second housing part in such a way that the housing parts are movable relative to each other, while the housing parts are connected to each other by at least one further section. For example, the further sections can be encompassed by the retaining device. Advantageously, the first housing part and the second housing part can be connected and / or detached from each other by means of tool-free actuation of the locking device. Tool-free here means in particular that the locking device can be actuated without any technical aids separate from the bearing. In particular, the locking device can be actuated by a person using only their hands, especially with just one hand.A tool-free locking device has the advantage that no tools are required to transfer the bearing from its operating state to its disassembly state during maintenance, thus simplifying maintenance and saving time. One-handed operation makes maintenance particularly easy and quick, and the additional provision of the holding device described here can be especially beneficial in this regard. In one embodiment, the locking device is configured to generate a clamping force between the first and second housing parts to establish the bearing's operating state. The housing parts are arranged and fixed relative to each other in the operating position, particularly by this clamping force. Advantageously, the first and second housing parts each have at least one radially and axially extending end face, with the end face of the first housing part facing the end face of the second housing part in the bearing's operating state. Preferably, the housing parts each have at least two end faces. The locking device is configured, in particular, to generate a clamping force between the housing parts in the bearing's operating state such that the end faces of the housing parts are pressed together by a contact force that is substantially perpendicular to the end faces. The clamping force...The contact force ensures that the position of the bearing core to the bearing housing can be reliably determined by a shaft, even under a comparatively high load on the bearing during operation. In one embodiment, the locking device comprises a lever element. Preferably, the lever element is mounted relative to and thus connected to one of the first and second housing parts, at least in the described disassembly position that the bearing assumes after transitioning from the operating state to the disassembly state, and particularly in the disassembly position and in the operating state, and especially in the subsequent disassembly position and in the operating state, particularly throughout the entire disassembly state and in the operating state. The lever element is preferably mounted relative to one of the housing parts such that it is movable relative to the first housing part and / or relative to the second housing part when the bearing is disassembled. In particular, the lever element is rotatable, preferably about an axis of rotation parallel to the bearing axis, relative to one of the housing parts.Preferably, the lever element is mounted on one of the housing parts in the operating state and, to achieve disassembly, is rotatable about an axis of rotation relative to that housing part, starting from the operating state. Preferably, to achieve disassembly, the lever element is rotatable about a first axis of rotation relative to the housing part and about a second axis of rotation relative to the other housing part or a connecting element connected to the other housing part, which preferably runs parallel to the bearing axis and thus parallel to the first axis of rotation. In particular, the lever element can be connected to the housing part and / or the other housing part without tools and, especially after the tool-free connection, can also be detached from it without tools.In particular, the lever element for transferring the bearing from the operating state to the disassembly state can be detached from one of the housing parts without tools, while remaining connected to another housing part. The leverage generated by the lever element allows the first and second housing parts to be fixed or connected to each other with high force, even without tools. Likewise, the fixation or connection can also be released again with high force using the lever element. This is particularly advantageous when the bearing according to the invention is used in conjunction with a shaft that has a large diameter and / or a long length, and correspondingly large forces act on the bearing. Advantageously, the locking device comprises a connecting element in addition to the lever element, wherein the connecting element and lever element preferably form a buckle. A buckle has the advantage of being particularly easy and quick to operate, while still providing a strong connection between the housing parts. In one embodiment, the connecting element is detachable, particularly without tools, and can be connected to the lever element and / or at least one of the first or second housing parts, particularly without tools. In another embodiment, the lever element is connected to one of the first and second housing parts via the connecting element in both the operating and disassembly states, and to the other of the first and second housing parts directly or via a further connecting element.If, in the disassembled state of the bearing, the connecting element is mounted on the lever element and one of the housing parts, such that it connects the lever element to this housing part, it is rotatable about an axis of rotation parallel to the bearing axis relative to the lever element and / or about another axis of rotation parallel to the bearing axis relative to the housing part. Advantageously, the connecting element can also generate a lever effect, so that an even stronger connection or force between the housing parts can be achieved by means of the connecting element in the operating state of the bearing. In a further embodiment, the lever element and / or the housing part connected to it have a hook-shaped section that extends, in particular, axially.In this configuration, the connecting element can engage with the lever element and / or the housing part in the operating state of the bearing to establish a connection, such that the section is at least partially encompassed by the hook. Furthermore, in one embodiment, the connecting element can also engage with the lever element and / or the housing part in the disassembled state to establish a connection. This corresponding design of the connecting element and the lever element or the housing part allows for the transmission of high forces between the housing parts. In particular, the connecting element for engaging the hook-shaped section has at least one axially extending pin-shaped section.Preferably, the connecting element is designed as a substantially rectangular frame, with the pin-shaped sections forming two opposing frame parts. The features and embodiments described below relate to the bearing according to claim 1 and / or to the bearing according to claim 7, wherein the embodiments may also have individual or all of the aforementioned features of the bearings according to the invention. In one embodiment, the bearing core is designed like a spherical cap with a spherical outer surface. Thanks to its spherically shaped outer surface, the bearing core is pivotably mounted relative to the bearing housing perpendicular to the longitudinal axis, so that, in the operating state of the bearing, it can be rotated relative to the bearing housing about an axis perpendicular to the bearing axis over a certain angular range. Preferably, however, the bearing core is secured against translational movement relative to the bearing housing with respect to both the axial and radial directions. In one embodiment, the bearing core comprises at least one first core element and at least one second core element, wherein the core elements are preferably identical. In the operating state of the bearing, the core elements can face each other with their radially and axially extending end faces. Preferably, the core elements are arranged radially adjacent to each other with their end faces facing each other, without undercuts, so that their end faces do not interlock. In one embodiment, the core elements are rotatable relative to each other about an axis perpendicular to the bearing axis in the operating state and / or in the disassembly state of the bearing. Preferably, the rotatability in the operating state is ensured by fixing the housing parts relative to each other and the core elements together forming the receptacle for the bearing core, but without a shaft being arranged in the receptacle.Preferably, the core elements can be removed from the bearing housing in the operating state and / or in the disassembly state after such a rotation relative to each other about the aforementioned axis. Preferably, the core elements are secured against removal from the bearing housing in the operating state only by the arrangement of a shaft in the receptacle. In a further embodiment, the core elements are arranged in the bearing housing such that they are rotatable about the bearing axis, at least in the disassembly state of the bearing. In this way, both core elements can be removed from the bearing housing even with the shaft passing through the bearing core, namely by first removing one core element, to which access has been made possible by moving the first and / or second housing part relative to each other, and then rotating the other core element into a position in which access to it is also possible. In one embodiment, the bearing housing preferably comprises exactly the first housing part and the second housing part. In another embodiment, the bearing core comprises exactly the first and the second core element. By providing exactly two housing parts and / or exactly two core elements, the bearing can be manufactured particularly simply and, moreover, mounted radially from the outside of a shaft particularly easily. In one embodiment, the bearing core is made of plastic, in particular from exactly one or more injection-molded parts. In another embodiment, the housing parts are made of plastic, in particular each from exactly one or more injection-molded parts. In another embodiment, the bearing core is made of a sliding material. Generally preferably, the sliding material is a tribologically optimized plastic.For example, polymers can be used to create a tribologically optimized plastic; for example, thermoplastics such as polyethylene, polypropylene, polyacetal, polycarbonate, polyamide, and polyvinyl chloride can be used. Polytetrafluoroethylene and, in the case of thermosets, phenolic resins are used. To further reduce friction, these plastics can contain lubricants, especially fine-particle solid lubricants, such as polymeric solid lubricants, waxes, molybdenum disulfide, or graphite. Such lubricant-containing polymers are also called tribopolymers. The features and embodiments described below relate to a bearing according to the invention which has both the features of the bearing according to claim 1 and the features of the bearing according to claim 7, wherein the embodiments may also have individual or all of the aforementioned features of the bearings according to the invention. In one embodiment, the fixing device of the bearing according to the invention comprises at least the holding means and the locking means. The holding means, in particular, has at least one degree of freedom. It is conceivable, in principle, that the holding means has several degrees of freedom. Preferably, however, the holding means has exactly one degree of freedom. Advantageously, the first housing part and the second housing part are movable relative to each other in the disassembled state of the bearing by means of the at least one degree of freedom of the holding means. In particular, the holding means has at least one degree of freedom such that the first housing part and / or the second housing part are rotatable relative to each other about the bearing axis.In one embodiment, the locking device and the holding device are designed to interact in such a way that the at least one degree of freedom of the holding device can be locked in the operating position when the locking device is actuated without tools. This lock enables the bearing to operate and fixes the housing parts relative to each other. "Lockable" means that after locking the at least one degree of freedom, the housing parts can no longer move relative to each other, so that the bearing is in the operating state. In another embodiment, the locking device and the holding device are additionally or alternatively designed to interact in such a way that the locking of the at least one degree of freedom of the holding device in the operating state can be released when the locking device is actuated without tools to move the bearing from the operating state to the disassembly state.In particular, the first housing part and the second housing part are movable relative to each other after the locking mechanism is released. The bearing according to the invention can be designed more simply and cost-effectively by means of a previously described interaction between the holding means and the locking means, since no additional means is required to lock or release the degree of freedom, but this can be achieved using the locking means that is already present. Furthermore, assembly and disassembly efforts can be reduced by only having to actuate the locking means. In one embodiment, the locking means and the holding means are arranged at least partially opposite each other in a direction perpendicular to the bearing axis. This advantageously ensures an optimal force flow for locking the at least one degree of freedom of the holding means by the locking means. The invention further relates to the use of a bearing for fixing the bearing to a shaft. Fixing the bearing to a shaft means that the radial position of the bearing and the shaft relative to each other is fixed. The bearing comprises a bearing housing with at least a first housing part and at least a second housing part. The bearing also comprises a bearing core having a receptacle designed as a through-hole extending along a bearing axis through the bearing core. Furthermore, the bearing core has a radial outer surface with which, in an operating state of the bearing, it at least partially bears against a corresponding inner surface of the bearing housing. In an operating state of the bearing, the inner surface of the bearing housing and the outer surface of the bearing core engage radially and axially, thus fixing the radial and axial position of the bearing core relative to the bearing housing.In the first step of use, the first housing part and the second housing part are positioned relative to each other in a disassembly position in the disassembled state of the bearing, particularly starting from a further disassembly position. Specifically, the disassembly position in which the housing parts are positioned relative to each other can already correspond at least substantially, and in particular completely, to the operating position of the housing parts in the operating state. In a second step of use, the first housing part and the second housing part are fixed to each other without tools in an operating position in the operating state of the bearing. It is also conceivable that the housing parts are moved from the disassembly position to the operating position by this tool-free fixing. This can be the case, for example, if the disassembly position does not already correspond substantially to the operating position.However, the housing parts can also be positioned relative to each other in a disassembly position that essentially corresponds to the operating position. In this case, the disassembly position becomes the operating position by fixing the housing parts to each other, without the housing parts changing their relative positions. In one embodiment of the application, the bearing has a holding means that may have some or all of the features described above with respect to the holding means. Preferably, the holding means is designed such that the first housing part and the second housing part are positioned in the disassembly position by a rotation relative to each other, in particular about the bearing axis, preferably exclusively about the bearing axis. Preferably, the housing parts are rotated at an angle of at least 90°, in particular at least 120°, in particular at least 150°, in particular at least 180° relative to each other. Preferably, the housing parts are positioned in the disassembly position by a rotation along a defined path. In one embodiment of the application, the bearing has a fixing device with a locking means, which may have some or all of the features described above with regard to the locking means. Preferably, the locking means is actuated without tools, so that, in particular, the first housing part and the second housing part can be fixed to each other in the operating position without tools by actuating the locking means. In one embodiment, the locking means comprises a connecting element and a lever element, wherein the connecting element and lever element preferably form a buckle. Preferably, the buckle is in an open state when the bearing is disassembled. This means that it is connected to the first housing part or the second housing part at one end and is unconnected at the other.Preferably, the housing parts are fixed to one another without tools by actuating the buckle, in particular its lever element, without tools and thereby closing it, especially by detachably connecting its second buckle end to the other end of the first or second housing part. Preferably, the first buckle end is formed on the lever element and the second buckle end on the connecting element, or vice versa. The buckle can also be designed such that, when the buckle is actuated, the housing parts are moved from the disassembly position to the operating position. In one embodiment of the application, the bearing core comprises at least one first core element and at least one second core element, wherein the core elements are preferably identical. The core elements and the bearing housing are preferably designed to correspond to each other such that the core elements arranged in the bearing housing are rotatable about the bearing axis, at least when the bearing is disassembled. If the first and / or second core element has been removed from the bearing housing, i.e., is not arranged in the bearing housing, then, in this embodiment, before positioning the housing parts in the disassembly position relative to each other, either the first core element or the second core element can be arranged in the first housing part or the second housing part by inserting it into the housing part from outside by means of a rotation about the bearing axis.Advantageously, the core element can be arranged in the bearing housing without having to remove a shaft passing through the bearing. The other core element can then be joined to the first or second core element, so that the core elements face each other with their radially and axially extending end faces. In particular, when joining the other core element, the first and / or the second core element is rotated around the bearing axis by the first or second core element. Specifically, the first and / or the second core element is rotated around the bearing axis at an angle of at least 90°, in particular at least 120°, in particular at least 150°, and in particular at least 180°.Preferably, only after joining both core elements to the shaft are the housing parts, starting from a further disassembly position which they particularly occupy while the core elements are arranged on the shaft, are moved into the disassembly position and then, by transferring the bearing from the disassembly state to the operating state, are placed in the operating position. The invention further relates to the use of a bearing that is fixed to a shaft in an operating state for releasing at least a part of the bearing from the shaft. The bearing comprises a bearing housing with at least a first housing part and at least a second housing part. The bearing also comprises a bearing core having a receptacle designed as a through-passage extending along a bearing axis through the bearing core. Furthermore, the bearing core has a radial outer surface with which, in an operating state of the bearing, it bears at least partially against a corresponding inner surface of the bearing housing. In the operating state of the bearing, the inner surface of the bearing housing and the outer surface of the bearing core engage radially and axially, thus defining a radial and axial position of the bearing core relative to the bearing housing.The first and second housing parts are fixed relative to each other in an operating position during the bearing's operation, particularly by means of a fixing device. In a first step of use, the first and second housing parts are separated without tools. This tool-free separation transforms the bearing from an operating state, in which the housing parts are in an operating position, to a disassembly state, in which the housing parts are in a disassembly position. The disassembly position can, in particular, essentially correspond to the operating position. In a second step of use, the first and second housing parts are moved relative to each other from the disassembly position to at least one further disassembly position, while the housing parts remain connected. In one embodiment of the application, the bearing has a fixing device with a locking means, which may have some or all of the features described above with regard to the locking means. In particular, the first housing part and the second housing part are fixed in their operating position relative to each other by means of the locking means when the bearing is in its operating state. Preferably, the locking means can be actuated without tools, so that the housing parts can be released from each other by actuating the locking means without tools. In one embodiment, the locking means comprises a connecting element and a lever element, wherein the connecting element and the lever element in particular form a buckle.Preferably, the buckle is in a closed position during the bearing's operating state, meaning that one end of the buckle is connected to the first or second housing part, and the other end of the buckle is connected to the first or second housing part. Preferably, the housing parts can be separated without tools by actuating the buckle, particularly its lever element, without tools, thereby opening it. Specifically, the buckle is opened by releasing the connection between its second end and the other end of the first or second housing part. In particular, the first end of the buckle is formed on the lever element and the second end on the connecting element, or vice versa. In one embodiment of the application, the bearing has a holding means that may have some or all of the features described above with regard to the holding means. Preferably, the holding means is designed such that the first housing part and the second housing part can rotate relative to each other, particularly around the bearing axis, preferably exclusively around the bearing axis, after the housing parts have been released. Preferably, the housing parts are moved from the disassembly position to at least one further disassembly position by a rotation relative to each other at an angle of at least 90°, particularly at least 120°, particularly at least 150°, particularly at least 180°. Preferably, the housing parts are moved from the disassembly position to at least one further disassembly position by a rotation along a defined path relative to each other. In one embodiment of the application, the bearing core comprises at least one first core element and at least one second core element, wherein the core elements are preferably identical. In the operating state of the bearing, the core elements can face each other with radially and axially extending end faces. The core elements and the bearing housing are preferably designed to correspond to each other such that the core elements arranged in the bearing housing are rotatable about the bearing axis, at least when the bearing is disassembled. In this embodiment, either the first core element or the second core element or both core elements can be rotated about the bearing axis after the housing parts have been detached without tools and moved from the disassembly position to at least one further disassembly position, with the first and / or second core element then being removed from the bearing housing.Advantageously, the rotation of the core elements allows both core elements to be removed from the bearing for maintenance purposes without having to first remove a shaft running through the bearing. Specifically, the first or second core element is removed first, and the other is then rotated around the bearing axis by the first or second core element until sufficient access to the core element is ensured, and then also removed. It is also conceivable that the first or second core element is rotated around the bearing axis before its removal, in which case the first and second core elements are rotated together. Specifically, the first and / or second core element is rotated around the bearing axis at an angle of at least 90°, in particular at least 120°, in particular at least 150°, and in particular at least 180°. The bearing in both of the aforementioned uses according to the invention may have some or all of the aforementioned features of the bearings according to the invention. The invention is explained in more detail below with reference to figures and exemplary embodiments. Figure 1 shows various exploded views of an embodiment of a bearing according to the invention in various schematic diagrams; Figure 2 shows various views of the embodiment of the bearing according to the invention in a disassembled state in various schematic diagrams; Figure 3 shows various views of the embodiment of the bearing according to the invention in an operating state in various schematic diagrams. Figure 1, comprising Figures 1a and 1b, shows various views of an embodiment of a bearing 1 according to the invention. Figures 1a and 1b each show an exploded view of the bearing 1, with Figure 1a showing a view from the upper left oblique angle and Figure 1b showing a view from the upper right oblique angle. The embodiment of a bearing 1 according to the invention shown in Figures 1a and 1b is explained below with reference to all the figures mentioned. The bearing 1 according to the invention comprises a bearing housing 2 with exactly two housing parts, a first housing part 2.1 and a second housing part 2.2. Furthermore, the bearing has a bearing core 3 with exactly two identically designed core elements, a first core element 3.1 and a second core element 3.2. The core elements 3.1, 3.2 each have two radially and axially extending end faces 3.3, the end faces 3.3 of the first core element 3.1 not being shown in Fig. 1. In the operating state of the bearing 1, the end faces 3.3 face each other and are in complete contact with one another. The core elements 3.1, 3.2 thus provide, with their inner surfaces 3.4, a receptacle for a shaft (not shown) which may pass through the bearing. In the operating state of the bearing 1, the receptacle is designed as a passage extending along a bearing axis X through the bearing core 3.The bearing axis X passing through the bearing core 3 is shown in Fig. 3, with further detailed reference to Fig. 3 below. The first housing part 2.1 and the second housing part 2.2 each have two radially and axially extending end faces 2.3 and 2.4, the end faces of the first housing part 2.1 being not shown in Fig. 1. In the operating state of the bearing, the end faces 2.3 and 2.4 are oriented towards and corresponding to each other such that they at least partially abut one another. Furthermore, the bearing housing 2 has an inner surface 2.5, with each of the housing parts 2.1 and 2.2 forming an angular segment of the inner surface 2.5. The inner surface 2.5 of the bearing housing 2 encloses the bearing core 3 in the operating state of the bearing 1. The inner surface 2.5 abuts a corresponding outer surface 3.5 of the bearing core 3, with each of the core elements 3.1 and 3.2 forming an angular segment of the outer surface 3.5. The outer surface 3 is the one currently in use and is generally preferred.5 is designed as a spherical outer surface, so that the bearing core 3 is shaped like a spherical cap. The inner surface 2.5 also has a corresponding spherical inner surface. Due to the spherical shape of outer surface 3.5 and inner surface 2.5, the surfaces 2.5 and 3.5 have a cross-sectional shape resembling a segment of a circular arc on their radially opposite sides in a cross-section extending radially along the bearing axis X. The circular arc segments formed by inner surface 2.5 and outer surface 3.5 are parallel to each other. Furthermore, the outer surface 3.5 of the bearing core 3 and the inner surface 2.5 of the bearing housing 2 interlock radially and axially in the operating state of the bearing, thus defining an axial position of the bearing core 3 relative to the bearing housing 2. The bearing 1 has a retaining element 4 integrally formed in the bearing housing 2, which is preferably designed as a rotary bearing. The retaining element 4 comprises an axially extending pin 4.1 fixedly arranged in a recess of the first housing part 2.1, and a hook-shaped element 4.2 integrated into the second housing part 2.2 and fixedly arranged to the remaining part of the second housing part 2.2, which has a receptacle corresponding to the pin 4.1 and also extending axially. The pin 4.1 is engaged by the hook-shaped element 4.2 in such a way that the pin 4.1 and the hook-shaped element 4.2 are rotatable relative to each other, thereby allowing the housing parts 2.1 and 2.2 to be moved relative to each other when the bearing 1 is disassembled. In this case, the holding means 4 only allows the two housing parts 2.1, 2.2 to rotate relative to each other about an axis of rotation parallel to the bearing axis X, so that the housing parts 2.1, 2.2. The holding means 4 allows the housing parts 2.1, 2.2 to be guided along a defined path from the disassembly position to at least one further disassembly position. Furthermore, in the disassembled state of the bearing 1, the holding means 4 holds the housing parts 2.1, 2.2 directly against each other, so that advantageously neither of the housing parts 2.1, 2.2 has to be placed at a location remote from the other housing part 2.1, 2.2 during maintenance. The bearing 1 has a fixing device with a locking means 5 that can be actuated without tools. The locking means 5 is generally preferably at least partially, and in particular completely, a means manufactured separately from the housing parts 2.1, 2.2. The locking means 5 comprises a lever element 5.1 and a connecting element 5.2, which together form a buckle. The lever element 5.1 has a first hook-shaped section 5.3 at a lower end, with which it engages a pin 2.6 provided on the second housing part 2.2 and fixedly arranged to the remaining part of the housing part 2.2, and extending axially, such that the lever element 5.1 is rotatable relative to the bearing housing 2 about an axis of rotation parallel to the bearing axis X in at least some disassembly positions in which the bearing 1 is in the disassembled state. At an upper end, the lever element 5.1 has a second hook-shaped section 5.4, which encompasses a first pin-shaped and axially extending section of the connecting element 5.2, which is essentially designed as a rectangular frame, such that connecting element 5.2 and lever element 5.1 are rotatable relative to each other about a rotational axis parallel to the bearing axis when the bearing 1 is in the disassembled state. The connecting element 5.2 has a second pin-shaped and axially extending section, which is arranged opposite the first pin-shaped section. The second pin-shaped section of the connecting element 5.2 is encompassed by a hook-shaped section 2.7 of the first housing part 2.1 such that connecting element 5.2 and first housing part 2.1 are rotatable relative to each other about a rotational axis parallel to the bearing axis X in at least some disassembly positions in which the bearing 1 is in the disassembled state. Furthermore, the second pin-shaped section of the connecting element 5.Section 2 and the hook-shaped section 2.7 of the first housing part 2.1 are designed to correspond to each other in such a way that the connection between the two sections can be easily and without tools. Furthermore, the lever element 5.1 is designed so that it can be gripped by a person and the locking device 5 can therefore be operated without tools. The combination of lever element 5.1 and connecting element 5.2, and the resulting leverage, allows the locking element 5 to advantageously apply a comparatively large force to secure the housing parts 2.1 and 2.2. Figure 2, comprising Figures 2a, 2b, and 2c, shows various views of the embodiment of the bearing 1 according to the invention, as depicted in Figure 1, in its disassembled state. Figure 2a shows a top view, Figure 2b a front view, and Figure 2c a sectional view of the front view. Reference is made below to all of the figures mentioned in Figure 2. In particular, the sectional view in Figure 2c shows how the retaining means 4 and the locking means 5 each engage the bearing housing 2 and connect the housing parts 2.1 and 2.2. In the disassembled state shown in Figure 2, the housing parts 2.1 and 2.2 are in a relative position to each other, which is subsequently referred to as the further disassembly position.The bearing can be in its disassembled state either before maintenance and after being returned to the operating state, or after maintenance and before being returned to the operating state. A shaft (not shown) may be guided through the bearing core 3 and along the bearing axis X. In this case, the second pin-shaped section of the connecting element 5.2 is already or still engaged by the hook-shaped section 2.7 of the first housing part 2.1, so that the rotation of the housing parts 2.1 and 2.2 relative to each other by an angle α, and thus other possible disassembly positions, are restricted by the locking device 5. If connecting element 5.2 and the first housing part 2.1 and / or lever element 5.1 and the second housing part 2.2 and / or connecting element 5.2 and lever element 5.1 are not yet or no longer connected to each other, the housing parts 2.1, 2.2, and 2.2 can be disassembled.2 are rotated to each other by a significantly larger angle α around the bearing axis X, which allows the housing parts 2.1, 2.2 to be advantageously moved into other further disassembly positions, thus ensuring better accessibility of the bearing core 3. In the further disassembly position shown in Fig. 2, in which the bearing 1 is in the disassembly state, the buckle formed by locking means 5.1 and connecting element 5.2 is not closed, so that the housing parts 2.1, 2.2 are not fixed relative to each other. Fig. 2 merely illustrates by way of example that the first core element 3.1 of the bearing core 3 is received in the first housing part 2.1 in the disassembly state of the bearing. Preferably, at least after the bearing 1 has been transferred from the operating state to the disassembly state and the housing parts 2.1, 2.2 have rotated relative to each other, the first core element 3.1 remains in contact with the second core element 3.2, so that relative movement occurs between the first housing part 2.1 and the first core element 3.1. The first core element 3.1 can then be easily removed from the shaft for maintenance. Alternatively or additionally, the second core element 3.1 can be...To wait 2, this can be manually rotated around the bearing axis X in the second housing part 2.2 so that it can be removed from the bearing housing 2 and taken off the shaft. Figure 3, comprising Figures 3a, 3b, and 3c, shows various views of the embodiment of the bearing 1 according to the invention, as depicted in Figures 1 and 2, in its operating state. Figure 3a shows a top view, Figure 3b a front view, and Figure 3c a sectional view of the front view. Reference is made below to all of the figures mentioned in Figure 3. Figure 3 shows the bearing 1 in an operating state after the housing parts 2.1 and 2.2 have been moved from the further disassembly position to a disassembly position, which essentially corresponds to the operating position of the housing parts 2.1 and 2.2, by means of the holding means 4, compared to the disassembly state shown in Figure 2. The buckle was then closed by rotating lever element 5.1 and connecting element 5.2 counterclockwise in the plane of the drawing by means of a tool-free actuation of lever element 5.1 about the bearing axis X.The closed buckle generates a clamping force between the end faces 2.3, 2.4 of the housing parts 2.1, 2.2 during operation, thus fixing them relative to each other in the operating position. This also fixes the position of the core elements 3.1, 3.2 relative to each other, enabling the bearing 1 to absorb forces from a shaft passing through the bearing core 3.
