Integrated speed reducer

Abstract

The invention discloses an integrated speed reducer. The integrated speed reducer comprises a box body provided with a cavity, an input shaft and an output shaft, wherein an input shaft hole and an output shaft hole are formed in the wall surface of the box body, the input shaft penetrates through the input shaft hole and is connected with an input gear, the output shaft penetrates through the output shaft hole and is connected with an output gear, and the output gear is in transmission connection with the input gear; the box body is provided with a pump seat and an oil conveying pipe; the pump seat comprises a base and an end cover which are integrally formed with the box body, the end cover covers the base in a sealing manner to form a cavity body, a gear pump is arranged in the cavity body, and the cavity body is provided with an oil outlet hole communicating with the cavity; and the oil conveying pipe is integrally formed with the box body, one end of the oil conveying pipe communicates with the lower part of the cavity, and the other end of the oil conveying pipe communicates with the cavity body. The integrated speed reducer has the advantages of being capable of saving lubricant oil and good in lubrication effect.

Description

technical field [0001] The invention relates to a speed reducer, in particular to an integrated speed reducer. Background technique [0002] With the decline of fossil fuels and the increasing pollution, more and more attention has been paid to energy-saving and environmentally friendly new energy vehicles. China's new energy vehicle industry continues to advance strongly in accordance with the planned route and production and sales targets, according to industry data released by the China Association of Automobile Manufacturers. In 2017, the production and sales of new energy vehicles in my country were close to 800,000, reaching 794,000 and 777,000 respectively, a year-on-year increase of 53.8% and 53.3%, respectively. In 2017, the production and sales of new energy vehicles accounted for 2.7% of the overall automobile market. With the expansion of the market for electric vehicles, the market demand for electric vehicles is also gradually increasing, and the output of reduc...

Problems solved by technology

With the expansion of the electric vehicle market, the market demand for electric vehicles is also gradually increasing, and the output of the reducer used on the corresponding electric vehicle is also gradually increasing. In the prior art, a certain amount of lubricating oil usually needs to be injected into the reducer so that To lubricate each transmission gear, the lubricating oil usually needs to cover 70% to 80% of the height of the gear with a larger diameter to fully ensure the lubricating effect. Before the gear rotates to the highest point, it splashes on the inner wall of the reducer, which makes the lubrication effect poor, and the splashed lubricating oil is easy to overflow from the gap and the interface, which will cause pollution and excessive loss
