[0007] Wherein, the inner wall of the outer ring of the bearing is provided with two groups of grooves, the inner wall of each groove is slidably connected with a movable block, and the outer surface of each movable block is connected to the outer surface of the conical movable ring.

[0008] Wherein, a group of threaded holes are provided on the upper surface of the bearing outer ring and the bottom surface of the bearing outer ring, and a bolt is threadedly connected to the inner wall of each threaded hole.

[0009] Wherein, the ends of the two groups of bolts that are close to each other are respectively in contact with the side surfaces of the two conical movable rings that are away from each other.

[0010] Wherein, a bearing inner ring is arranged inside the bearing outer ring.

[0011] Wherein, a group of rolling bodies are rotatably connected inside the retaining frame body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides an adjustment component and utilizes a conical movable ring to fix the retainer body. By adjusting the position of the conical movable ring, the retainer body can be controlled to be pressed tightly, thereby adjusting the tightness of the retainer body to meet different usage requirements.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a bearing with a cage tension adjustment structure, including a bearing outer ring 1, a cage body 4 is arranged inside the bearing outer ring 1, an adjustment component 3 is arranged inside the bearing outer ring 1, and the adjustment component 3 includes two conical movable rings 303 movably installed inside the bearing outer ring 1.

[0022] The outer surfaces of the two conical movable rings 303 are in contact with the outer surface of the retainer body 4 , and the conical movable rings 303 can be used to fix the retainer body 4 .

[0023] Among them, two groups of grooves 304 are opened on the inner wall of the bearing outer ring 1, and the inner wall of each groove 304 is slidably connected with a movable block 305. The outer surface of each movable block 305 is connected to the outer surface of the conical movable ring 303. The grooves 304 and the movable blocks 305 can limit the conical movable ring 303, thereby improving its reliability in use.
