An integrated structure of motor end cover and gear chamber, motor and air compressor

Abstract

An integrated structure of a motor end cover and a gear chamber, comprising: an integrated housing, one side of the integrated housing is connected with the motor housing, and the other side is connected with the supercharger housing, and a gear is arranged inside the integrated housing room; waterway structure, the waterway structure is located in the integrated housing on the side close to the motor housing, and the waterway structure is connected with the waterway system in the motor housing; oil circuit structure, the oil circuit structure is located in the integrated housing On one side close to the supercharger housing, the oil passage structure communicates with the gear chamber. Combining the gear chamber housing and the front end cover of the motor as a whole shortens the length of the entire air compressor, reduces the weight of the entire air compressor, saves a set of circulating water pipelines, reduces manufacturing costs, and improves the overall air compressor performance. aesthetic appearance.

Description

Technical field: [0001] The invention relates to an integrated structure of a motor end cover and a gear chamber, a motor and an air compressor. Background technique: [0002] The current air compressor includes a motor and a supercharger, a gear chamber is arranged between the motor and the supercharger, and a separate gear chamber housing is arranged outside the gear chamber, which is arranged between the motor front cover and the supercharger housing. There is lubricating oil in the gear chamber, so there are several oil passages in the gear chamber casing, which are used for the oil inlet, oil outlet and oil quantity monitoring of the lubricating oil in the gear chamber. The gears in the gear chamber will generate heat during high-speed rotation. After a long time, the gear chamber needs to be cooled. Therefore, a circulating water circuit is also provided in the gear chamber housing, and a water inlet and a water outlet are provided on the gear chamber housing. During ...

AI Technical Summary

Problems solved by technology

[0003] (1) There are both oil passages and water passages in the gear chamber casing, which increases the thickness of the gear chamber casing, thereby increasing the length of the entire air compressor. In the automotive field that requires very high space dimensions, it is undoubtedly reduced. The competitiveness of the product has been compromised, and it cannot meet the requirements of compressing the space inside the car as much as possible;

[0004] (2) The increase in the thickness of the gear chamber shell leads to an increase in the weight of the entire air compressor, which does not conform to the current trend of lightweight in the automotive field;

[0005] (3) The water inlet and outlet of the gear chamber housing and the motor are respectively connected with a set of circulating water pipelines, which not only increases the manufacturing cost, but also affects the appearance of the entire air compressor.
