The two ends of the first retaining frame 1 are respectively fixedly connected with connection blocks 42. The connection grooves 41 and the connection blocks 42 are adapted in size. During installation, the two connection blocks 42 can be respectively inserted into the corresponding connection grooves 41 to connect the first retaining frame 1 and the second retaining frame 2 together. When the first retaining frame 1 or the second retaining frame 2 is damaged, it is only necessary to separate the connection grooves 41 and the connection blocks 42 and replace the damaged parts, thereby avoiding Since the retaining frame of the existing automobile bearing is mostly a complete circular ring, it needs to be replaced as a whole when replacing, which increases the replacement cost. Two circular grooves 43 are provided on the connecting block 42, and a telescopic rod 44 is fixedly connected in the circular groove 43. A round ball 45 is fixedly connected to one end of the telescopic rod 44. Two limiting grooves 46 are provided in the connecting groove 41. When the connecting groove 41 is connected to the connecting block 42, the two telescopic rods 44 can be stretched so that the two round balls 45 are respectively stuck in the corresponding limiting grooves 46, so that the connection between the first retaining frame 1 and the second retaining frame 2 is more stable. A first spring 47 is sleeved on the telescopic rod 44, and one end of the first spring 47 is fixedly connected to the round ball 45. The first spring 46 is provided on the telescopic rod 44. The other end of 7 is fixedly connected to the inner wall of the circular groove 43. When the connecting groove 41 and the connecting block 42 are connected, the round ball 45 will be squeezed to shrink into the circular groove 43. At this time, the first spring 47 is in a contracted state. Therefore, when the round ball 45 contacts the limiting groove 46, the round ball 45 is clamped into the limiting groove 46 under the action of the rebound elastic force of the first spring 47, making the connection operation more convenient. A clamping groove 48 is provided on the connecting block 42, a through groove 414 is provided on the second retaining frame 2, and a sliding groove 410 is provided on the first retaining frame 1.

The positioning rod 49 is connected to the clamping groove 48 and the through groove 414. The sizes of the grooves 414 are adapted to each other. When the connecting groove 41 is connected to the connecting block 42, the slide bar 411 is slid downward so that the locking rod 49 is inserted into the groove 48 and the through groove 414 at the same time, which can further enhance the stability of the connection between the connecting groove 41 and the connecting block 42. A second spring 413 is fixedly connected to the inner bottom wall of the slide groove 410, and one end of the second spring 413 is fixedly connected to the slide bar 411. When the slide bar 411 is slid upward, the second spring 413 is in a stretched state. Therefore, when the connecting groove 41 is connected to the connecting block 42, the connecting rod 412 is released, and the locking rod 49 is locked into the groove 48 and the through groove 414 under the action of the rebound elastic force of the second spring 413, further improving the convenience of the connection operation.

[0033] Embodiment 3

[0034] Reference Figure 4On the basis of the first and second embodiments, the present embodiment provides a lubrication structure 5 which is commonly provided on the first retainer 1 and the second retainer 2. The lubrication structure 5 is mainly composed of a plurality of oil injection holes 51 which are equidistantly provided on the first retainer 1 and the second retainer 2, respectively. The plurality of oil injection holes 51 are connected one by one with the plurality of mounting grooves 6. Lubricating oil can be injected through the plurality of oil injection holes 51 so that the lubricating oil flows into the mounting groove 6 to lubricate the roller 3, thereby improving the service life of the product. An annular groove 52 is commonly provided on the first retainer 1 and the second retainer 2, and the annular groove 52 is connected with the plurality of oil injection holes 51. When lubricating oil is injected into the annular groove 52, the lubricating oil will enter the plurality of oil injection holes 51 along with the annular groove 52, thereby improving the efficiency of lubrication.

[0035] Working principle: during installation, the two connecting blocks 42 can be respectively inserted into the corresponding connecting grooves 41 to connect the first retaining frame 1 and the second retaining frame 2 together. When the first retaining frame 1 or the second retaining frame 2 is damaged, it is only necessary to separate the connecting groove 41 and the connecting block 42 and replace the damaged parts, thereby avoiding the situation where the retaining frame of the existing automobile bearing is mostly a complete circular ring, so the entire ring needs to be replaced during replacement, which increases the replacement cost. After the connecting groove 41 and the connecting block 42 are connected, the two telescopic rods 44 can be stretched so that the two round balls 45 are respectively inserted into the corresponding limiting grooves 46, so that the connection between the first retaining frame 1 and the second retaining frame 2 is more stable. When the connecting groove 41 and the connecting block 42 are connected, the round balls 45 will be squeezed and contracted into the circular groove 43. At this time, the first spring 47 is in a contracted state. Therefore, when the round balls 45 contact the limiting groove 46, the round balls 45 are inserted under the action of the rebound elastic force of the first spring 47. When the slide bar 411 is slid upward, the second spring 413 is in a stretched state. Therefore, when the connecting groove 41 is connected to the connecting block 42, the connecting rod 412 is released, and the locking rod 49 is inserted into the locking groove 48 and the through groove 414 under the action of the rebound elastic force of the second spring 413, which further improves the convenience of the connection operation. Lubricating oil can be injected through the plurality of oil filling holes 51, so that the lubricating oil flows into the mounting groove 6 to lubricate the roller 3, thereby improving the service life of the product. When the lubricating oil is injected into the annular groove 52, the lubricating oil will enter the plurality of oil filling holes 51 along the annular groove 52, thereby improving the efficiency of lubrication. During the rotation of the roller 3, the lubricating oil will flow between the rollers 3 through the plurality of oil passages 53, thereby improving the lubrication effect.
