AI Technical Summary

Technical Problem

The protective covers of existing noise-reducing motors are inconvenient to install and remove, and vibrations during high-speed operation result in poor sound insulation, affecting the normal use of the motor.

Method used

A structure including a soundproof box and a protective box was designed. The motor body is placed inside the soundproof box, and the protective box is connected to the soundproof box. Vibration is reduced by a buffer mechanism, noise is absorbed by sound insulation material, and the motor is fixed by a clamping plate. The buffer mechanism consists of a support rod, a buffer block and a buffer spring. The support rod cooperates with the sliding groove to achieve buffering and shock absorption.

Benefits of technology

It effectively reduces the noise level of the motor when running at high speed, improves the stability and sound insulation of the motor, and ensures the normal operation of the motor.
