Problems solved by technology

[0003] The motor is an important device that converts electricity generated by new energy into mechanical energy. The reliability and efficiency of the motor directly affect the utilization of new energy. Due to the short maintenance time of the existing motor, the failure rate is high for a long time, and the reliability is not good. Strong and other reasons have increased the failure rate of new energy vehicles during driving and reduced people's desire to buy new energy vehicles

Abstract

The invention discloses a rolling bearing system of an automobile motor. The system comprises a housing of the motor, bearing components and a motor shaft provided with a first oil path along an axisdirection. The two opposite surfaces of the housing are provided with the bearing components, the motor shaft and the bearing components are in fitting installation to form a support for the motor shaft, and upper parts of the two bearing components are provided with oil inlet holes. The bottom of one bearing component is provided with an oil groove connected to an oil pool, and the oil inlet holeof the upper part is connected to a liquid out port of the first oil path. The oil inlet hole of the upper part of the other bearing component is connected to the oil pool, the lower part of the bearing component is also provided with an oil groove which is connected to a liquid in port of the first oil path, and an oil liquid loop is formed between the two bearings of the motor through the firstoil path in the motor shaft. The invention aims to provide the rolling bearing system of the automobile motor with the prolongation of the maintenance period of the motor bearings and the increase ofthe reliability of the bearings.

Description

technical field [0001] The invention relates to the field of electromechanical equipment, in particular to a rolling bearing system of an automobile motor. Background technique [0002] my country has been developing at a high speed for a long time in the past, which consumes a lot of energy and has caused a lot of damage to the environment, including air quality. Therefore, in recent years, my country has vigorously promoted clean and sustainable new energy. [0003] The motor is an important device that converts electricity generated by new energy into mechanical energy. The reliability and efficiency of the motor directly affect the utilization of new energy. Due to the short maintenance time of the existing motor, the failure rate is high for a long time, and the reliability is not good. Strong and other reasons have increased the failure rate of new energy vehicles during driving and reduced people's desire to buy new energy vehicles. Contents of the invention [00...
