STORAGE ARRANGEMENT

Description

[0001] The invention relates to a bearing arrangement comprising a vibrating body, a base body with at least two spaced-apart supports between which the vibrating body is received, and suspension elements with which the vibrating body is suspended in the base body, wherein a vibrational movement of the vibrating body in a linear direction is enabled, according to the preamble of claim 1.

[0002] Bearing arrangements according to the preamble of claim 1 are known by way of example from the publications CN 212 055 653, CN 110 979 435 and CN 112 038 533.

[0003] Bearing arrangements for suspending a body that can be set into vibration have long been known and are widely used. They are particularly common in machines and vehicles where vibrations are generated in a body that should not be transmitted to a base body, or only in a weakened form. These arrangements typically incorporate spring-loaded bearing elements or rubber buffers.

[0004] With such a mounting using flexible bearing elements, the vibrating body is not only capable of movement in a desired linear direction, but also in other directions. To ensure the desired guidance of the vibrating body in a defined linear direction of movement, it is generally known to provide a corresponding linear guide between the vibrating body and the base body, which ensures a directed linear movement of the vibrating body during oscillation.

[0005] However, such an additional linear guide device leads to additional contact surfaces, which can result in an undesirable transmission of vibrations from the vibrating body to the base body, as well as additional friction losses during the vibrating movement.

[0006] The invention is based on the TaskThe basis is to specify a bearing arrangement in which linear movement of a vibrating body relative to a base body is ensured in a particularly efficient manner.

[0007] The problem is solved by a bearing arrangement having the features of claim 1. Preferred embodiments of the invention are specified in the dependent claims.

[0008] The bearing arrangement according to the invention is characterized in that at least two approximately rod-shaped suspension elements are arranged between the vibrating body and each support, which extend transversely to the linear direction in a suspension direction, that the rod-shaped suspension elements are pivotably connected to the vibrating body and / or the base body via a pivot bearing about a pivot axis which is directed transversely to the linear direction and to the suspension direction, and that the rod-shaped suspension elements and / or the pivot bearings are designed to be flexible, exhibiting linear compressibility and linear elongation in the suspension direction.

[0009] A fundamental aspect of the invention is to mount a vibrating body between two supports by means of at least two preferably parallel, rod-shaped suspension elements positioned transversely to the intended linear direction of vibration of the vibrating body. To enable movement in this arrangement with two lateral, parallel, rocker-like suspension elements, the suspension elements and / or the pivot bearings on the suspension elements are designed to be at least partially flexible or elastic. This allows for a certain degree of linear compression and linear elongation in the suspension direction, so that, in combination with the double arrangement of the rod-shaped suspension elements, movement of the vibrating body in the desired linear direction, which is perpendicular to the suspension direction, is ensured.

[0010] Preferably, the lateral and opposing suspension elements are arranged and designed symmetrically to each other, so that transverse forces occurring during operation cancel each other out and a defined linear movement of the vibrating body is given during vibration, even without an additional linear guide.

[0011] A preferred embodiment of the invention consists in the rod-shaped suspension element being a telescopic rod with a sleeve-shaped first rod section and a second rod section that is guided linearly within the first rod section. This design of the suspension element as a telescopic rod ensures linear displacement of the two rod sections relative to each other in the longitudinal direction of the rod. This creates a suspension element that is movable in its rod direction and thus in the suspension direction, but is rigid in a transverse direction.

[0012] According to a further development of the invention, it is particularly advantageous that the rod-shaped suspension element comprises an elastic element. The suspension element can be partially or entirely elastic.

[0013] It is particularly preferred that the elastic element is a spring and / or a rubber material. In a telescopic rod, a helical spring or an element made of a rubber material can thus be arranged between the two rod elements. For the purposes of this invention, a rubber material is to be understood broadly and basically includes any synthetic or natural material, in particular a plastic, which has a suitable modulus of elasticity for elastic behavior similar to rubber.

[0014] In principle, the rod-shaped suspension elements can only be supported at one end by a pivot bearing. According to one embodiment of the invention, a particularly reliable suspension is achieved by connecting the rod-shaped suspension elements at both ends to the base body and the vibration body via pivot bearings. This significantly reduces friction losses. The pivot bearing allows a certain degree of pivoting or rotating movement about a pivot axis.

[0015] According to the invention, the swivel bearing is elastically designed with at least one elastic bearing element. In principle, the swivel bearing can be a bushing or a rolling bearing. By partially or completely incorporating at least one elastic bearing element into the swivel bearing, the desired flexibility in the suspension direction can be achieved, even with an otherwise rigid suspension element.

[0016] In principle, the pivot bearing can be designed in any way. According to one embodiment of the invention, it is particularly advantageous for the pivot bearing to have a sleeve-shaped rubber bushing. The rubber bushing allows, on the one hand, a certain degree of pivoting of the articulated suspension element about the pivot axis of the pivot bearing, which corresponds to a central axis of the rubber bushing. At the same time, a rubber bushing also allows a certain degree of displacement transverse to the direction of the pivot axis, so that the desired flexibility in the suspension direction is achieved in the bearing arrangement according to the invention.

[0017] Particularly good bearing properties are achieved through further development by providing the rubber bushing with a metal sleeve on its inner and / or outer surface. The resulting swivel bearing can thus be reliably inserted into corresponding mounting bores, and bolt-shaped elements can also be inserted into the bushing to hold the suspension elements. This is achieved by metal sleeves on the inner or outer surface of the rubber bushing.

[0018] The bearing arrangement according to the invention can be used in a variety of ways. A preferred embodiment consists in at least one bearing arrangement being mounted on a vehicle. In particular, the bearing arrangement according to the invention allows a motor or drive unit of a vehicle to be mounted on the vehicle chassis with minimal vibration. This can result in particularly good driving comfort for a car, train, or other vehicle.

[0019] A further advantageous embodiment of the invention consists in at least one bearing arrangement being arranged in a machine, in particular a machine tool or a power tool. This allows vibrations occurring during operation of the machine to be directed and dampened relative to a machine body. The machine can, in particular, be a soil compactor with a vibratory plate, wherein a vibration drive with a vibratory plate is mounted with low vibration relative to the rest of the machine body, thus enabling particularly gentle operation, for example, during manual operation of a vibratory plate.

[0020] The vibratory drive can also be mounted on an excavator arm, so that the vibrations resulting from the vibratory operation are not transmitted to the excavator arm, or only to a limited extent. In a machine tool, vibrations resulting from a press or punch press, in particular, can be absorbed in a particularly advantageous manner relative to a base body.

[0021] The invention is explained in more detail below with reference to a preferred embodiment, which is shown schematically in the drawings. In the drawings show: Fig. 1 a first schematic side view of a bearing arrangement according to the invention with a vibration body in an upper position; Fig. 2 a second schematic side view of the bearing arrangement according to the invention. Fig. 1 with the vibrating body in a central position; and Fig. 3 a schematic side view of the bearing arrangement of Fig. 1 and Fig. 2with the vibrating body in a lower vibration position.

[0022] A bearing arrangement 10 according to the invention comprises a vibration body 20, which is received between two supports 32 of a base body 30 and is suspended on each side by two rod-shaped suspension elements 40 so as to oscillate freely in a linear direction of movement. The linear direction of movement is Fig. 1 The position is indicated by a double arrow. The vibrating body 20 can, in particular, be a vibration-generating device or a drive, especially an unbalanced drive, such as that used to drive a vibratory plate compactor. Accordingly, the base body 30 with the brackets 32 can be designed or attached to an excavator arm.

[0023] To achieve a largely linear oscillation of the vibrating body 20, the four suspension elements 40 are rod-shaped, with their longitudinal extension corresponding to a suspension direction. The suspension direction is perpendicular to the defined linear oscillation of the vibrating body 20.

[0024] The swing-like suspension elements 40 are pivotally or deflectibly connected at their two free ends to the support 32 on one side and to the vibration body 20 on the other via pivot bearings 14. Each pivot bearing 14 has a central rubber bushing 16 made of an elastically deformable rubber material. An inner metal sleeve 17 is arranged on the inside of the rubber bushing 16, and an outer metal sleeve 18 on the outside. The pivot bearing 14 thus enables a certain pivoting or rotating movement of the suspension elements 40 about the respective pivot axis, which in the illustrated embodiment is perpendicular to the plane of the drawing.

[0025] The elasticity of the pivot bearings 14 thus achieved enables a linear oscillatory movement of the vibrating body 20 in the direction of the arrow shown between the two parallel and spaced-apart supports 32, even when using rigid rod-shaped suspension elements 40.

[0026] From the in Fig. 1 In the upper vibration position of the vibrating body 20 shown, the vibrating body 20 can move via an internal vibration or oscillation drive to a middle vibration position according to Fig. 2 to a lower vibration position according to Fig. 3 The suspension elements 40 move. The suspension elements 40 perform a certain rotational movement about their respective pivot axis on the bracket 32. Due to the rigid design of the suspension elements 40 in the illustrated embodiment, the following occurs when approaching the mean oscillation position according to Fig. 2In the pivot bearings 14, due to their elasticity, a certain displacement of the inner metal sleeve 17 and thus of the pivot axis relative to the outer metal sleeve 18 occurs, as schematically shown in Fig. 2 This is illustrated by arrows on the lower pivot bearings 14. This allows the swing-like suspension elements 40 to pivot downwards.

[0027] During a further downward movement of the vibrating body 20 from the central position, the inner metal sleeve 17 can move back into its central position relative to the rubber bushing 16 and the outer metal sleeve 18, as shown in Fig. 3 shown.

[0028] Preferably, the Figure 1 and 3 The maximum deflection position in the linear direction of movement of the vibrating body 20 is shown, whereby in these two positions the pivot bearings 14 can each assume the same relaxed position.

[0029] By designing the suspension elements 40 and the pivot bearings 14 identically on both sides of the vibration body 20, symmetrical guidance and suspension of the vibration body 20 can be achieved. This allows a defined linear vibration motion of the vibration body 20 to be achieved without additional linear forced guidance.
