AI Technical Summary

Technical Problem

Existing motor lubrication methods require manual hand-held injection, which is time-consuming, labor-intensive, and difficult to control the injection volume, resulting in high labor intensity.

Method used

An automatic lubrication motor shaft was designed, which uses an automatic lubrication system consisting of a storage tank, an electric push rod, and a one-way valve. The electric push rod drives a piston block to automatically inject lubricating oil into the motor, and the lubricating oil is replenished by negative pressure when it is used up, thus achieving automatic replenishment.

Benefits of technology

It reduces the intensity of manual labor, realizes the automatic injection and replenishment of lubricating oil, and improves the efficiency and accuracy of lubrication operations.
