AI Technical Summary

Technical Problem

Existing synchronous pulleys are prone to generating heat and noise during rapid rotation, leading to accelerated wear and environmental pollution. Furthermore, traditional designs suffer from uneven heat distribution, resulting in uneven impact force and easy breakage during use.

Method used

A stamped synchronous wheel was designed, which adopts a structure with annular support plate, reinforcing ribs, wear-resistant plate and heat dissipation holes. Noise is reduced by sound-absorbing grooves, heat dissipation grooves and heat dissipation holes improve heat dissipation efficiency, and trapezoidal reinforcing ribs enhance support, thus achieving lightweight and stable transmission.

Benefits of technology

It effectively reduces vibration, noise, and heat during operation, improves the overall strength and service life of the synchronous pulley, and reduces weight and energy consumption, making it suitable for mass production.

Abstract

The utility model discloses a punch-formed synchronizing wheel, and relates to the technical field of transmission assemblies. Comprising an annular supporting plate, a plurality of equidistant silencing grooves are formed in the top of the annular supporting plate in a penetrating mode, at least two equidistant reinforcing ribs are fixedly connected to the inner side of the inner wall of the supporting plate in the radial direction, and a connecting ring is fixedly connected to one side of each reinforcing rib. Through the arrangement of the supporting mechanism and the heat dissipation mechanism, in the using process, firstly, the power shaft penetrates through the clamping boss and is fixed, then the power shaft drives the teeth to rotate and drives a component meshed with the teeth to move to achieve power transmission, main loads are borne through the annular supporting plate in the rotating process, stress is dispersed through the reinforcing ribs, and therefore the power transmission efficiency is improved. And then the teeth of the wear-resisting plate are in contact with a matching part, abrasion is reduced, meanwhile, the heat dissipation holes and the heat dissipation grooves accelerate air flowing, the device can effectively reduce vibration noise in the operation process, meanwhile, the weight is reduced, the energy efficiency is improved, meanwhile, an air convection channel is formed, and the heat dissipation efficiency is further improved.
