AI Technical Summary

Technical Problem

During use, the synchronous wheel is prone to cause the chain to jump and fall off due to excessive load, improper installation, wear and damage, which affects the stability and efficiency of riding.

Method used

A synchronous wheel with an anti-detachment structure is designed, including a driving gear and a driven gear, a limiting structure and an installation structure with an anti-detachment structure are installed. The chain is prevented from being disengaged by a press roller and a baffle. The shell composed of a vertical plate and a connecting plate is fixed to the driving gear and the driven gear. Combined with the design of the spring and slider, it ensures that the chain does not disengage when the teeth jump.

Benefits of technology

Effectively prevent the chain from falling off the gear after jumping teeth, reduce the impact on riding stability and efficiency, and improve the reliability of the synchronization wheel.

Abstract

The utility model discloses a synchronizing wheel with a function of preventing a chain from disengaging, which comprises a driving gear and a driven gear, the driving gear is connected with the driven gear through a chain, and the driving gear and the driven gear are respectively provided with a chain-disengaging-preventing structure. And the chain falling prevention structure comprises a limiting structure for preventing the chain from being separated from the driving gear and the driven gear and a mounting structure for fixing the limiting structure. By means of the mode, the synchronizing wheel with the function of preventing the chain from disengaging is provided with the chain disengaging preventing structure, the chain can be prevented from disengaging from the gear after tooth skipping occurs, and the influence of tooth skipping on riding stability and efficiency is reduced.
