Description

Technical field

[0001] The following descriptions relate to an assembly device for positioning a gap seal in a gap of a bearing, in particular a blade bearing, which enables simple, quick, and reliable assembly. Furthermore, the following descriptions relate to a method for positioning a gap seal on a bearing. Technical background

[0002] German patent application DE 20 2012 104 057 U1 discloses a bicycle tire lever for assisting in the removal and installation of bicycle tires or inner tubes on / from rims. German patent application DE 10 2006 053 832 A1 relates to an element for sealing a rolling bearing, in particular a blade bearing for wind turbines. German patent application DE 10 2011 109 605 A1 deals with an assembly tool and method for attaching an elastic seal to a vehicle door frame.

[0003] From EP 2 672 133 B1 a large rolling bearing with a gap seal sealing the gap between the bearing rings is known.

[0004] The object of the invention is to provide an assembly device for improving the ease of mounting gap seals on large slewing bearings, in particular blade bearings of wind turbines. Such large slewing bearings often have diameters of several meters. Accordingly, the gap seals also have a diameter of several meters.

[0005] Based on this situation, the task at hand is to propose an assembly device that simplifies the assembly of a gap seal and reduces the required assembly time. Description - Technical Solution

[0006] The present problem is solved by the features of the independent claim. Advantageous embodiments are specified in the dependent claims, the description, and the drawings. Where technically feasible, the teachings of the dependent claims can be combined arbitrarily with those of the main and dependent claims.

[0007] In particular, the problem is solved by a mounting device for arranging a gap seal at least partially in a gap extending axially and circumferentially between an inner bearing ring and an outer bearing ring of a bearing, in particular a blade bearing, wherein the gap seal has a circumferentially extending first sealing lip with at least one first sealing edge which forms a mounting groove open towards the gap for at least partially receiving the mounting device, wherein the first sealing lip is further designed for positioning within a sealing groove open towards the gap and extending circumferentially along the inner bearing ring or outer bearing ring.wherein the assembly device has a curved base body for screwing the first sealing lip into the sealing groove and a first end section arranged on the base body with a receiving edge for positive and / or force-fit arrangement in the mounting groove of the gap seal, wherein the assembly device further has a handle element arranged on a second end section for handling and guiding the assembly device during assembly, and wherein the assembly device has a drive element extending from the base body for positive-fit contact with a sealing foot of the gap seal that can be positioned within an anchor groove, wherein the drive element is designed for positive-fit engagement of a sealing foot of the gap seal that can be positioned within an anchor groove in the direction of the gap.

[0008] The mounting device allows the gap seal to be easily and cost-effectively positioned on the bearing. In particular, the first sealing lip can be screwed into the sealing groove over the gap. This is made possible primarily by the curved base body of the mounting device, which has a substantially convex-concave cross-section.

[0009] The following sections explain advantageous aspects and subsequently describe preferred modified embodiments. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be explicitly stated.

[0010] It is preferred that the sequence of process steps can be varied, unless a specific sequence is technically required. However, the aforementioned sequence of process steps is particularly preferred.

[0011] Where ordinal numbers, such as "first," "second," etc., are used, for example to designate a component, an element, a process step, or a process action, these ordinal numbers are solely for differentiation in the designation and do not indicate any dependencies or sequences. This means, in particular, that a device does not need to have a "first component" to have a "second component." A device can also have a "first component" and a "third component" without necessarily having a "second component." Multiple units with the same ordinal number are also possible, for example, multiple "first components."

[0012] Alternatively or additionally, the assembly device may include a drive element extending from the base body for positive-locking contact with a sealing foot of the gap seal that can be positioned within an anchor groove. In particular, the drive element is designed to positively engage a sealing foot of the gap seal, which can be positioned within an anchor groove, in the direction of the gap. The anchor groove is located on a bearing ring opposite the sealing groove. For example, if the sealing groove is located on the outer bearing ring, the anchor groove is located on the inner bearing ring. The anchor groove extends along the circumferential direction of the respective bearing ring.

[0013] Alternatively or additionally, the assembly device may be provided with a marking on the base body to indicate an assembly position. In particular, the marking may be a color marking and / or a structural marking, especially a notch, groove, and / or projection. Specifically, the marking is located on the base body between the drive element and the second end section. The marking allows the operator to see that the first sealing lip of the gap seal has been correctly positioned in the sealing groove. Only a portion of the first sealing lip is screwed into the sealing groove by the assembly device. The marking, particularly in conjunction with a reference marking on the inner and / or outer bearing ring, can indicate that a predetermined arrangement or position of the first sealing lip within the sealing groove has been achieved.This allows the gap seal to be easily and securely positioned on the bearing in the correct installation position.

[0014] Alternatively or additionally, the assembly device may be designed as a forming tool and / or a flat tool. In particular, the base body is designed to have a convex-concave curved arc shape. The assembly tool can be manufactured by primary forming processes and / or, in particular, by forming processes. The assembly device is made primarily of sheet metal and has a base body with a curved shape. The convex-concave base body facilitates the insertion or screwing of the first sealing lip into the sealing groove. The base body can be supported and rotated against a bearing ring opposite the sealing groove by means of its convex curved surface. The convex curved surface of the base body supports the insertion movement and facilitates the insertion of the first sealing lip into the sealing groove. This allows the gap seal to be easily and securely positioned on the bearing.

[0015] Alternatively or additionally, the receiving edge can be rounded. Specifically, the receiving edge is designed to match the contour of the mounting groove, or vice versa. The rounded receiving edge prevents damage to the gap seal in the area of ​​the first sealing edge. In particular, the receiving edge has a cross-sectional profile that slopes from the outside to the inside. Furthermore, the specific design of the receiving edge facilitates engagement with the mounting groove. The rounded edge also makes it easier to move the mounting device circumferentially after the first sealing lip has reached its insertion position, thus positioning the first sealing lip in the sealing groove across its entire circumference. The rounded receiving edge also facilitates the removal of the mounting device from the gap seal once it has been correctly positioned in the sealing groove.

[0016] Alternatively or additionally, the mounting device can be made of plastic or a metal alloy. A plastic mounting device can reduce wear on the gap seal during assembly. A metal alloy mounting device can be made thinner, thus simplifying assembly.

[0017] Alternatively or additionally, the mounting device may have a width that depends on the diameter of the gap seal or one of the bearing rings. In particular, the mounting device is wider as the diameter of the gap seal or the bearing rings increases. Specifically, the width of the mounting device is 30 to 200 millimeters, and more specifically, 50 to 100 millimeters. Since the receiving edge is essentially straight, the width must also be smaller for smaller diameters.

[0018] The problem is further solved by a method for arranging a gap seal at least partially in a gap extending axially and circumferentially between an inner bearing ring and an outer bearing ring of a bearing, in particular a blade bearing, with a mounting device which can be designed and further developed as described above, comprising the following steps: - Positioning the receiving edge of the mounting device in the mounting groove of the first sealing edge of the first sealing lip; - Screwing the first sealing lip at least partially through the gap into the sealing groove; - Unscrewing the mounting device from the gap; - Pressing the sealing foot into the anchor groove.

[0019] This method allows the gap seal to be quickly and easily attached to the bearing.

[0020] Alternatively or additionally, it can be provided that, after the first sealing lip has been screwed in, the assembly device is moved circumferentially until the first sealing lip is positioned within the sealing groove along its entire circumference, with the sealing base being pressed into the anchor groove along its entire circumference. By screwing the first sealing lip into the sealing groove once and then moving the assembly device circumferentially, particularly along the sealing groove, the first sealing lip can be positioned within the sealing groove over its entire circumference. This can speed up or simplify the installation of the gap seal.

[0021] It is also conceivable to rotate the first sealing lip into the sealing groove at several positions spaced apart around the circumference of the bearing rings. This can simplify the assembly process, especially with large and very large diameters of the gap seal and bearing rings.

[0022] According to one embodiment of the inventive method, the curved base body has a convex outer surface with which it bears against the bearing ring opposite the bearing ring containing the sealing groove when the first sealing lip is screwed into the sealing gap, when the mounting device is screwed out of the gap, and when the mounting device is moved circumferentially. This ensures secure guidance of the mounting device and rapid installation of the gap seal. At the same time, damage to the gap seal caused by uncontrolled movements of the mounting device is prevented.

[0023] According to one embodiment of the inventive method, the curved base body has a concave inner surface, with a drive element extending from the inner surface for positive-locking contact of a sealing foot of the gap seal to be positioned within an anchor groove. Pre-positioning of the sealing foot relative to the anchor groove occurs simultaneously with the positioning of the first sealing lip in the sealing gap in a single operation. This enables particularly fast and efficient assembly of the gap seal. The sealing foot and the first sealing lip are positioned simultaneously in their respective assembly positions using the assembly device. After unscrewing the assembly device from the gap, the sealing foot only needs to be inserted into the anchor groove to complete the assembly of the gap seal. Brief description of the drawings

[0024] A preferred technical solution is explained in more detail below with reference to the accompanying drawings and preferred embodiments. The term "figure" is abbreviated as "Fig." in the drawings.

[0025] The drawings show Fig. 1 a schematic side view of a first embodiment of an assembly device; Fig. 2 a schematic front view of the assembly device according to Fig. 1; and Fig. 3 a sectional view of an assembly arrangement with an assembly device according to Fig. 1. Detailed description of the drawings

[0026] The described embodiments are merely examples that can be modified and / or supplemented in various ways within the scope of the claims. Each feature described for a particular embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a particular claim category can also be used accordingly in an embodiment of a different claim category.

[0027] Fig. 1 and Fig. 2 show a schematic side view ( Fig. 1) and front view ( Fig. 2) a first embodiment of a mounting device 10 for arranging a gap seal 12 at least partially in a gap 18 of a bearing 20, in particular a blade bearing for supporting a rotor blade of a wind turbine, extending axially and circumferentially between an inner bearing ring 14 and an outer bearing ring 16, wherein the gap seal 18 has a circumferentially extending first sealing lip 22 with at least a first sealing edge 24, which forms a mounting groove 26 open towards the gap 18 for at least partially receiving the mounting device 10, wherein the first sealing lip 22 is further designed for positioning within a sealing groove 28 open towards the gap 18 and extending circumferentially along the inner bearing ring 14 or outer bearing ring 16, wherein the mounting device 10 has a curved base body 30 for screwing the first sealing lip 22 into the sealing groove 28 and a [missing element] on the base body 30The mounting device 10 has a first end section 32 with a receiving edge 34 for positive and / or force-fit assembly in the mounting groove 26 of the gap seal 12, wherein the mounting device 10 further has a handle element 38 arranged on a second end section 36 for handling and guiding the mounting device during assembly. The mounting device 10 also has a drive element 40 extending from the base body 30 for positive-fit contact with a sealing foot 44 of the gap seal 12, which can be positioned within an anchor groove 42. By means of the drive element 40, the sealing foot 44 is carried along when the first sealing lip 24 is screwed into the sealing groove 28 and pre-positioned in an area in front of the anchor groove 42. From this pre-position, the sealing foot can be easily inserted into the anchor groove 42 after removal of the mounting device 10. For secure assembly of the gap seal 12, the mounting device 10 has a handle element 38 arranged on the base body 30.The arranged marking 46 indicates a predefined mounting position. The width 48 of the mounting device 10 depends on the diameter of the gap seal 12 or the diameter of the bearing rings 14, 16. A wider mounting device 10 enables quick mounting of the gap seal 12 along its entire circumference.

[0028] Fig. Figure 3 shows a sectional view of an assembly arrangement with an assembly device 10 according to Fig. 1, wherein the mounting device 10 acts upon the gap seal 12 in the direction of the gap 18. The receiving edge 34 is arranged within the mounting groove 26 of the first sealing lip 22. Additionally, the drive element 40 rests on the sealing base 44 of the gap seal 12, whereby the gap seal 12 is acted upon by the mounting device 10 in the direction of the gap 18. By rotating the mounting device 10, the first sealing lip 22 is moved or inserted into the sealing groove 28. The marking 46 arranged on the base body 30 ensures that the first sealing lip 22 has reached a predetermined position within the sealing groove 28. Subsequently, the mounting device 10 can be moved circumferentially to position the first sealing lip 22 over its entire circumference in the sealing groove 28.Once the first sealing lip 22 is positioned in the sealing groove 28 over its entire circumference, the mounting device 10 is unscrewed. The sealing base 44 is positioned in the area of ​​the anchor groove 42 in such a way that it can be pressed into the anchor groove 42, for example, by an operator of the mounting device 10. This enables quick and secure installation.

[0029] Advantageously, the concave-convex curved shape of the base body 30 of the mounting device 10 supports the turning motion for inserting the first sealing lip 22 into the sealing groove 28. This allows for a predetermined insertion motion for the first sealing lip 22, enabling its secure positioning in the sealing groove 28 in a simple manner. Uncontrolled movement during the insertion of the first sealing lip 22 and any resulting potential damage to the gap seal 12 are thus effectively prevented. Similarly, the concave-convex curved shape of the base body 30 also supports a controlled unscrewing motion of the mounting device 10 after the first sealing lip 22 has been positioned in the sealing groove 28 across its entire circumference. Here, too, damage to the gap seal 12 is avoided.

[0030] Even while the mounting device 10 is moved circumferentially to position the first sealing lip 22 over its entire circumference in the sealing groove 28, the support of the base body 30 with its convexly curved surface on the bearing ring, which is opposite the bearing ring with the sealing groove 28, enables a controlled and guided movement of the mounting device 10 in the circumferential direction, thereby enabling safe and quick assembly without damage to the gap seal 12.

[0031] In the Fig.In the embodiment shown in Figures 1 to 3, a handle element 38 is depicted which is angled towards the convex outer surface of the base body 30. It is understood that this is only one of many possible configurations of the handle element 38 on the second end section 36. The angled handle element 38 shown facilitates the screwing in, unscrewing, and circumferential movement of the mounting device 10.

[0032] It is also conceivable (though not shown in the figures) not to angle the handle element 38. In this case, the handle element 38 is simply formed by the curved end section 36 of the base body 30 itself. It is also conceivable to angle the handle element 38 towards the concave inner surface of the base body 30. Furthermore, it is conceivable to provide several handle elements 38 instead of a single handle element 38, which are, for example, designed as lever-shaped handle elements 38 that can be grasped by the operator, thus facilitating operation. It is also conceivable to angle several handle elements 38 from the base body 30 at different angles.
