Problems solved by technology

With the improvement of various performance parameters of motor mechanical equipment, the motor has a high test of the wear resistance of the motor bearing in the heavy-load, high-speed, high-precision working environment, and the existing lubricating oil can no longer meet the current demand. Not only will it aggravate the damage of the motor bearing, but also there is a certain risk, which affects the safe operation of the motor

Abstract

Relating to the technical field of new material processing, the invention discloses a method for improving the wear resistance of a motor running bearing. By studying the performance of a superfine nano material, a prepared lubricating oil additive is added into base lubricating oil to lubricate a motor running bearing, thus greatly improving the lubricating properties of the lubricating oil, reducing the friction coefficient, and playing a pressure-resistant and antifriction role, even under the conditions of high load and high rotating speed, the bearing anti-wear capability of a rotating shaft can be permanently guaranteed. The lubricating oil additive material can reinforce the lubricating properties of base oil, reduce the roughness of a contact surface, has good dispersity in lubricating oil and small dosage, can effectively fill micro pits, scratches and the like on a friction contact surface in a motor running process, repair a damaged friction surface and reduce wear, and evenunder an oil shortage state, the material also can form an excellent surface lubricating protection film, thus broadening the use occasion of the material.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a method for improving the wear resistance of a running bearing of a motor. Background technique [0002] Motors are divided according to the type of working power supply: they can be divided into DC motors and AC motors. Whether it is an AC motor or a DC motor, the motor bearing is a necessary component of the motor's work, and its quality directly affects the normal operation of the motor. The main function is to support the mechanical rotating body of the motor, reduce the friction coefficient in the working rotation, and ensure the accuracy of operation. [0003] At present, in order to improve the lubrication performance of the motor running bearings, various types of lubricating oils are used to reduce the coefficient of friction to achieve anti-wear and anti-pressure effects. With the improvement of various performance parameters of motor mech...
