AI Technical Summary

Technical Problem

Existing geared motors rely on the oil stored in the lubrication box for lubrication, which can easily lead to oil loss, resulting in poor lubrication and affecting the stability and service life of the equipment.

Method used

A geared motor with optimized lubricating oil sealing structure was designed, including a supply pump, an oil storage tank, a filter assembly, and a compensation assembly. The supply pump drives the lubricating oil in the oil storage tank to circulate to the lubrication tank. The filter assembly filters impurities, and the compensation assembly is set in the lubrication tank to automatically replenish the oil and ensure lubrication effect.

Benefits of technology

It enables automatic compensation and recycling of lubricating oil, avoids lubrication failure caused by insufficient oil, ensures continuous lubrication of equipment, reduces the frequency of manual intervention, and improves the operational stability and service life of equipment.
