AI Technical Summary

Technical Problem

The existing gear reducer's lubrication structure cannot be flexibly adjusted according to the actual lubricating oil temperature, resulting in poor lubrication effect, high energy consumption, and affecting the service life of the reduction gears.

Method used

A lubrication structure including a guide tube, an electromagnetic pump, a refrigeration component, and a temperature sensing component was designed. The temperature sensing component monitors the temperature, controls the refrigeration component to cool down the oil in a timely manner, and adjusts the lubricating oil flow through a valve column to achieve active regulation and cooling of the lubricating oil.

Benefits of technology

It improves lubrication, reduces energy consumption, and extends the service life of the speed reducer.
