Motor bearing lubrication system

Abstract

The invention relates to a motor bearing lubrication structure, in particular to a motor bearing lubrication system. The motor bearing lubrication system solves the problem that lubricating grease always leaks and throws out, and is always accumulated in an outer bearing cover and external foreign matters are easy to enter the bearing when the traditional motor bearing lubrication structure is used. The motor bearing lubrication system comprises an end cover, a sealing ring, an inner bearing cover and an outer bearing cover, wherein the outer bearing cover is provided with a grease discharging hole; the inner side of the end cover is sheathed with a bearing chamber; the end surface of the outer side of the bearing chamber is provided with an oil deflector ring; a second O-shaped seal ringis installed between the end surface of the inner side of the oil deflector ring and the end surface of the outer side of the bearing chamber; and a labyrinth seal is arranged between the end surfaceof the outer side of the seal ring and the end surface of the inner side of the outer baring cover. According to the motor bearing lubrication system, the problem that the lubricating grease always leaks and throws out, and is always accumulated in the outer bearing cover and the external foreign matters are easy to enter the bearing when the traditional motor bearing lubrication structure is used can be effectively solved, and the motor bearing lubrication system is suitable for the motor bearing lubrication.

Description

technical field [0001] The invention relates to a motor bearing lubricating structure, in particular to a motor bearing lubricating system. Background technique [0002] The operating conditions of wind turbines are usually harsh. If the generator shuts down or replaces the generator due to bearing problems, the resulting economic loss is quite huge, so it is required to grease the bearings without shutting down, and while ensuring lubrication, the working temperature of the bearings must be guaranteed kept below a certain temperature. Such as figure 1 As shown, the existing motor bearing lubrication structure generally includes an end cover 1 , a sealing ring 2 , an inner bearing cover 3 , and an outer bearing cover 4 . The outer bearing cover 4 is provided with a grease outlet 5 . When the motor is working, the bearing 12 is assembled on the motor shaft 13, and the motor rotor is supported by the end cover 1. During grease lubrication, the grease lubricates the bearin...
