Wear-resistant motorcycle sprocket with a protection device

By setting a connection structure between the movable ring and the seat ring on the motorcycle sprocket, the problem of difficult-to-control position of the protective plate is solved, enabling adaptive adjustment of the chain thickness and stable connection of the sprocket, thus improving wear resistance and transmission efficiency.

AI Technical Summary

Technical Problem

In practical applications, the protective plate of existing wear-resistant motorcycle sprockets with protective devices tends to move away from the sprocket, making it difficult to accurately control the distance between the sprocket and the protective plate, resulting in wear of the chain due to meshing deviation.

Method used

The protective stop is designed to be fitted with a movable ring on the protective stop and a seat ring on the support. The movable ring is connected to the seat ring by a fastening bolt through a groove on the seat ring. This controls the movement of the protective stop along the axis of the support to accommodate changes in the thickness of the chain. The protective stop is also housed in the groove of the locating ring and flush with the surface of the sprocket body, thus avoiding increasing the connection thickness between the sprocket and the motorcycle wheel axle.

Benefits of technology

This invention allows for adjustment of the position of the protective stop based on the chain thickness, reducing wear, maintaining the stability of the connection between the sprocket and the motorcycle wheel axle, without affecting the existing structure, and improving the service life and transmission efficiency of the sprocket.

Abstract

The application provides a wear-resistant motorcycle sprocket with a protection device, and relates to the technical field of motorcycle sprockets.The wear-resistant motorcycle sprocket with a protection device comprises a sprocket main body, support pieces and a protective baffle.Two strip-shaped grooves are arranged in the interiors of the two support pieces.Tightening bolts are arranged in the interiors of the strip-shaped grooves, and rubber rings are sleeved on the exteriors of the tightening bolts.The support piece comprises a transition ring, which is in the shape of a circular truncated cone and has a positioning ring integrally formed at the narrow end and a seat ring integrally formed at the wide end.The protective baffle comprises a baffle ring, and the inner side of the baffle ring is integrally formed with a movable ring.The technical key points are as follows: the movable ring on the protective baffle is sleeved with the seat ring on the support piece through the strip-shaped groove, and the tightening bolt is threadedly connected with the movable ring, so that the protective baffle can be moved along the axis of the support piece to adapt to the thickness of the chain belt outside the sprocket main body, and the actual thickness of the chain belt can be adjusted.
