Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a damping cover. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a mechanical rotating body and reduce the friction coefficient during its movement. An electric tailgate, that is, an automatic trunk opening and closing system for an automobile, usually needs to use a lifting rod to play a role in support and buffering, ensuring that the trunk can be automatically opened or closed smoothly and safely. The key point of this design is to provide sufficient resistance to ensure that the trunk lid can stop at any position and prevent the trunk lid from sliding down randomly.

[0003] The damping effect on the traditional electric tailgate lifting rod is achieved by setting devices such as a motor air spring and a bearing damper, which have disadvantages such as high cost and large occupied space. Therefore, some designs use damping bearings to solve the above problems. Most traditional damping bearings are one-way damping and are mostly used on vertically installed ball screws. This is because the friction of the ball screw is extremely small and it is rolling friction, so it cannot be self-locking. When the slider is at a high position, if the power is cut off, its gravity will cause the ball to rotate, driving the screw to rotate and fall by itself. The one-way damping of the damping bearing is to prevent this self-rotation. When the damping bearing rotates forward, there is no resistance, and when it rotates backward, the resistance is large, or it cannot rotate backward.

[0004] The damping bearing is also called a one-way bearing. The traditional one-way bearing is also called a needle clutch. In order to achieve one-way movement or damping effect, it often sets a relatively complex structure between the fixed ring and the moving ring of the bearing, that is, between the inner and outer rings of the bearing. This design has a high cost and is relatively complex to install.

[0005] Based on this, a damping cover is proposed, providing a new solution to solve the above technical problems. Content of the Utility Model

[0006] Based on this, in view of the technical problems raised in the above background art, it is necessary to provide a damping cover that is installed between the inner and outer rings of a bearing to provide a damping force.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] The damping cover specifically includes a damping cover skeleton and a rubber part. The outer peripheral edge of the damping cover skeleton is provided with a plurality of elastic crimps. The rubber part includes a rubber ring or a rubber sleeve;

[0009] The rubber ring is bonded to the outer periphery of the inner hole of the damping cover skeleton;

[0010] The rubber sleeve is wrapped around the outside of the damping cover skeleton.

[0011] Preferably, a first clamping groove is formed on the outer periphery of the inner hole of the damping cover skeleton.

[0012] Preferably, the rubber ring is bonded to the damping cover skeleton through the first clamping groove.

[0013] Preferably, a second clamping groove is formed on the inner side of the bottom of the damping cover skeleton, and the rubber sleeve is covered on the damping cover skeleton through the first clamping groove and the second clamping groove.

[0014] Preferably, the number of the elastic curled edges is greater than [number].

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Through the arrangement of a plurality of elastic curled edges, the edge of the damping cover skeleton has a certain elasticity, so as to facilitate pressing the damping cover skeleton into the inner side of the outer ring of the damping bearing.

[0017] 2. Through the cooperation of the rubber ring and the damping cover skeleton, during use, the rubber ring is in interference fit contact with the inner ring of the damping bearing, improving its damping effect and making the damping cover stronger; by covering the rubber sleeve on the outer side of the damping cover skeleton, the damping cover can be used in cooperation with both the inner and outer rings of the bearing at the same time. At this time, the damping cover skeleton plays a supporting role, greatly improving the strength and damping effect of the damping cover, and at the same time improving the stability during use. On the other hand, when the rubber sleeve is in interference fit with both the inner and outer rings of the damping bearing at the same time, the range of its damping force can be increased.

[0026] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , a damping cover, comprising a damping cover skeleton 1 and a rubber part. The outer peripheral edge of the damping cover skeleton 1 is provided with a plurality of elastic crimps 2. The rubber part includes a rubber ring 3 or a rubber sleeve 4. By cooperating the rubber ring 3 with the damping cover skeleton 1, during use, the rubber ring 3 is in interference fit contact with the inner ring of the damping bearing, improving its damping effect and making the damping cover stronger; by covering the rubber sleeve 4 outside the damping cover skeleton 1, the damping cover can be used in cooperation with both the inner and outer rings of the bearing at the same time. At this time, the damping cover skeleton 1 plays a supporting role, greatly improving the strength and damping effect of the damping cover, and at the same time improving the stability during use. On the other hand, when the rubber sleeve 4 is in interference fit with both the inner and outer rings of the damping bearing at the same time, the range of its damping force can be increased.

[0028] During use, the damping cover is arranged between the inner and outer rings of the damping bearing and on both sides of the steel ball cage. When the damping cover skeleton 1 and the rubber ring 3 are combined to form the damping cover, the damping effect is achieved through the interference fit between the rubber ring 3 and the inner ring of the bearing. In actual use, in order to improve the damping effect, guide grooves can be opened on the inner ring to enhance the damping effect. Through the cooperation between the guide grooves and the damping cover, during the rotation of the bearing, the damping cover slides regularly on the outer periphery of the inner ring. At the same time, due to the function of the guide grooves, a part of the rubber ring 3 is always located inside the guide grooves and cooperates with them, enabling the inner ring to rotate only under a certain torsional force, thus playing a damping role, further enhancing stability and reliability, ensuring torque stability at high and low temperatures, increasing service life, and reducing costs. When the rubber sleeve 4 and the damping cover skeleton 1 are combined to form the damping cover, the damping effect is achieved through the interference fit connection between the rubber sleeve 4 and the inner and outer rings. In actual use, the setting of the damping cover skeleton 1 makes the damping cover stronger, thereby increasing the service life. On the other hand, during actual use, guide grooves can be selectively opened on the inner side of the outer ring of the bearing, and the damping effect and the upper limit of the damping force can be improved through the cooperation between the rubber sleeve 4 and the guide grooves.

[0029] A clamping groove one 5 is provided on the outer periphery of the inner hole of the damping cover skeleton 1.

[0030] The rubber ring 3 is bonded to the outer periphery of the inner hole of the damping cover skeleton 1 through the clamping groove one 5. The setting of the clamping groove one 5 makes the cooperation between the damping cover skeleton 1 and the rubber ring 3 more stable and tight.

[0031] A clamping groove two 6 is provided on the inner side of the bottom of the damping cover skeleton 1. The rubber sleeve 4 is wrapped on the damping cover skeleton 1 through the clamping groove one 5 and the clamping groove two 6.

[0032] The number of the elastic flanges 2 is more than 10. When the number of the elastic flanges 2 is large, the length of each elastic flange 2 is small. When the damping cover skeleton 1 is pressed into the outer ring of the bearing, the deformation of the elastic flanges 2 is small, which is convenient for their recovery after being installed into the outer ring and improves their stability.

[0033] The usage process of a damping cover provided by the present utility model is as follows:

[0034] The damping cover is arranged between the inner and outer rings of the damping bearing and on both sides of the steel ball cage. When the damping cover skeleton 1 and the rubber ring 3 are combined to form a damping cover, the damping effect is achieved through the interference fit between the rubber ring 3 and the inner ring of the bearing. In actual use, in order to improve the damping effect, a guiding groove can be opened on the inner ring to enhance the damping effect. Through the cooperation between the guiding groove and the damping cover, during the rotation of the bearing, the damping cover slides regularly on the outer circumference of the inner ring. At the same time, due to the effect of the guiding groove, a part of the rubber ring 3 is always located inside the guiding groove and cooperates with it, so that the inner ring needs to rotate under a certain torsional force, thereby playing a damping role, further enhancing stability and reliability, ensuring torque stability at high and low temperatures, increasing service life, and reducing costs; when the rubber sleeve 4 and the damping cover skeleton 1 are combined to form a damping cover, the damping effect is achieved through the interference fit connection between the rubber sleeve 4 and the inner and outer rings. In actual use, the setting of the damping cover skeleton 1 makes the damping cover stronger, thus increasing the service life. On the other hand, in actual use, a guiding groove can be selected to be opened on the inner side of the outer ring of the bearing, and the damping effect and the upper limit of the damping force can be improved through the cooperation between the rubber sleeve 4 and the guiding groove.
