[0002] The roll locking nut snap ring is an important component in the roll equipment. Its main function is to ensure that the roll will not loosen or fall off due to vibration or other external forces during operation.

[0003] Roller locking nut snap ring is usually composed of two semicircular snap ring bodies, one end of the two semicircular snap ring bodies is directly connected by a pin shaft, and the other end is locked by a bolt (such as Figure 1 As shown in the figure), in this connection method, since the two semicircular retaining ring bodies are directly connected by a pin shaft, they are easy to get stuck, which makes installation and disassembly inconvenient. In addition, the other ends of the two semicircular retaining rings are directly connected by bolts, which makes the threads easy to be damaged. Once the threads are damaged, the entire piece will be scrapped. Therefore, a roller locking nut retaining ring is designed to solve the above problems. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a roller locking nut clamping ring, which solves the problems of the original clamping ring being inconvenient to disassemble and assemble and the thread being easily damaged.

[0007] Furthermore, the depth of the embedding groove is equal to the depth of the connecting plate.

[0008] Furthermore, the bolt through-hole is smoothly arranged.

[0009] Furthermore, the diameter of the locking screw is smaller than the diameter of the bolt through-hole, and the diameter of the locking nut is larger than the diameter of the bolt through-hole.

[0010] Furthermore, positioning holes are provided at both inner and outer ends of the upper surface of the locking screw, and a cotter pin is provided through the positioning hole.

[0011] Furthermore, the distance between the two positioning holes is equal to the sum of the distance between the two bolt mounting grooves and the thickness of the two nuts when the bolt connection ends of the upper semicircular ring and the lower semicircular ring are in contact.

[0012] From the above technical solution, it can be seen that the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a connecting plate, so that the upper and lower semicircular rings of the clamping ring are connected indirectly instead of directly, and the rotating shaft is changed from one to two, so that the clamping ring is more convenient and quick to disassemble and assemble, and is not easy to get stuck.
