Description

[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to match the shaft and rotate with the shaft; the outer ring is used to match the bearing seat and play a supporting role; the rolling element is evenly distributed between the inner and outer rings with the help of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; the cage can make the rolling element evenly distributed, guide the rolling element to rotate and play a lubricating role.

[0003] After long-term use, existing bearings will wear and deform, which will cause the balls inside the bearings to shift. The shifting of the balls will cause the bearings to rotate unsteadily and produce abnormal sounds and vibrations during operation, affecting the quietness and stability of the equipment and shortening the service life of the entire bearing.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] Reference Figure 1-Figure 5 A ball anti-drift anti-shake silent bearing comprises a bearing body 1, an outer ring 2 is arranged on the outer wall of the bearing body 1, a ball 4 is arranged inside the bearing body 1, the number of the ball 4 is set to be multiple, and a plurality of anti-drift components are arranged inside the bearing body 1;

[0029] Each set of anti-deviation components includes a mounting block 3, the number of mounting blocks 3 is set to be multiple, and multiple balls 4 are arranged corresponding to the multiple mounting blocks 3. Two driving blocks 13 are provided on one side of each mounting block 3, and a clamping block 10 is provided inside each mounting block 3. Every two driving blocks 13 are used to drive the corresponding two clamping blocks 10 to fix the position of the balls 4.

[0030] Reference Figure 1-Figure 5, multiple mounting blocks 3 and multiple balls 4 are distributed in a circular array along the axis of the bearing body 1, each mounting block 3 is provided with a through hole 6, each mounting block 3 is provided with a cavity 9, each through hole 6 is connected with the corresponding cavity 9, the inner wall of each clamping block 10 matches the outer wall of the ball 4, both ends of each clamping block 10 are fixedly connected with a fixing block 11, each fixing block 11 is slidably connected with the inner wall of the corresponding cavity 9, one side of each driving block 13 is fixedly connected with a threaded rod 12, each threaded rod 12 is threadedly connected with the corresponding two fixing blocks 11, two springs 14 are fixedly connected between each two fixing blocks 11, each ball 4 is located between the corresponding two clamping blocks 10, one side of each mounting block 3 is provided with a groove 5, each driving block 13 is located inside the corresponding groove 5, and each mounting block 3 is threadedly connected with the corresponding threaded rod 12.

[0031] The anti-deviation component can play a limiting role when installing the ball 4, preventing the ball 4 from deviating during use. The specific operation method is that by rotating the two driving blocks 13, since the heights of the fixed block 11 and the clamping block 10 match the height of the cavity 9, the two clamping blocks 10 will clamp toward the ball 4 when the driving block 13 is rotated. Since the clamping position of the clamping block 10 is located in the middle and upper position of the ball 4, the ball 4 will be limited when the clamping block 10 is clamped, avoiding the deviation of the ball 4 during use, ensuring that the ball 4 always remains in the correct position during use, ensuring the rotation stability of the bearing body 1, and extending the service life of the entire bearing body 1. When the ball 4 is damaged and needs to be replaced, it only takes one to reversely rotate the driving block 13, and the two clamping blocks 10 will loosen and the ball 4 can be taken out for replacement.

[0032] Reference Figure 2 and Figure 4 , each mounting block 3 is fixedly connected to one side close to the bearing body 1 with two mounting strips 15, the outer wall of the bearing body 1 is provided with multiple groups of slide grooves 8, the number of each group of slide grooves 8 is set to two, each slide groove 8 is slidably connected to the corresponding mounting strip 15, each slide groove 8 is interference fit with the corresponding mounting strip 15, each mounting strip 15 is made of elastic material, the outer wall of the bearing body 1 is provided with multiple circular grooves 7, one side of each rolling ball 4 is located inside the corresponding circular groove 7, and the inner wall of each circular groove 7 is provided with a friction sponge.

[0033] The sliding connection and interference fit between the mounting strip 15 and the slide groove 8 help ensure the stability of the connection between the mounting block 3 and the bearing body 1, reduce the possibility of loosening, and facilitate quick installation and removal of the mounting block 3. The mounting strip 15 is made of elastic material and can provide a certain buffer during installation and use. The provision of the friction sponge can reduce the noise generated by the ball 4 during use.

[0034] Working principle: When limiting the ball 4, by rotating the two driving blocks 13, since the heights of the fixed block 11 and the clamping block 10 match the height of the cavity 9, the two clamping blocks 10 will clamp the ball 4 when the driving block 13 is rotated. Since the clamping position of the clamping blocks 10 is located in the middle and upper part of the ball 4, the ball 4 will be limited when the clamping blocks 10 are clamped. When the ball 4 is damaged and needs to be replaced, the ball 4 can be taken out for replacement by simply rotating the driving block 13 in the opposite direction and loosening the two clamping blocks 10.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
