AI Technical Summary

Technical Problem

During operation, the bearings in the speed reducer generate a lot of heat due to friction, which leads to an increase in temperature, affects service life and lubrication performance, and thus reduces transmission efficiency.

Method used

Design a transition flange structure with built-in cooling function, including flange body, bearing, rotating shaft, refrigeration mechanism, spiral tube, temperature sensor and controller. Through the cooling system composed of cooling chamber and spiral tube, combined with temperature sensor and electric flow valve, real-time monitoring and regulation of temperature near bearing can be achieved, and the flow rate of cooling water can be controlled to keep the temperature within a reasonable range.

Benefits of technology

It effectively reduces bearing temperature, extends its service life, maintains the good performance of lubricating oil, prevents lubricating oil leakage, and improves the working efficiency of the reducer.
