AI Technical Summary

Technical Problem

Traditional single-row toothed sprockets have a relatively small load capacity and are not suitable for transmitting large power applications, resulting in a relatively low transmission ratio.

Method used

A powder metallurgy multi-row toothed sprocket was designed. A central fixed ring is fixedly installed on the sprocket spindle, and a left adjustment ring and a right adjustment ring are movably installed on both sides of the central fixed ring. A displacement adjustment component is set to adapt to chain meshing with different position deviations. The load capacity and transmission ratio are improved by synchronous transmission through multi-row meshing teeth.

Benefits of technology

It achieves a large load capacity, is suitable for transmitting high power, and can achieve a higher transmission ratio, adapting to chain meshing connections with different positional deviations.

Abstract

This utility model discloses a powder metallurgy multi-row toothed sprocket, including a sprocket spindle. A central fixed ring is fixedly installed on the sprocket spindle, and a left adjusting ring and a right adjusting ring are movably installed on the sprocket spindle. The central fixed ring, the left adjusting ring, and the right adjusting ring are all provided with meshing teeth. Two displacement adjustment components are provided on the sprocket spindle, and the two displacement adjustment components are respectively connected to the left adjusting ring and the right adjusting ring. This powder metallurgy multi-row toothed sprocket has multiple rows of meshing teeth on the sprocket spindle spindle. During use, the multiple rows of meshing teeth are used simultaneously, resulting in a larger load capacity of the sprocket spindle spindle, making it suitable for transmitting higher power and achieving a higher transmission ratio. The displacement adjustment components, by rotating the outer disc to drive the rotating rod, can adjust the position of the left or right adjusting ring, accommodating chains with different positional deviations for meshing connection.
