reducer housing (4)

With the rapid development of the automobile industry and the increasing number of car ownership, pollutant emissions are increasing, environmental problems are becoming more and more prominent, and the development of new energy vehicles has become the main trend of the future development of the automotive industry.com. Reducer is one of the core components of electric vehicle transmission system, which directly bears the impact of motor and wheel rotation, and its life span directly affects the reliability and economy of electric vehicles. Therefore, it is important to research and develop the reducer for new energy vehicles. Planetary gear reducer, also known as planetary reducer and Ho-Service reducer, is widely used. As an alternative to fixed drive shaft transmission, multiple planetary wheels share the load between them thus making rational use of the internal gear unit to improve efficiency. Compared with other reducers planetary reducers have the advantages of small size, high efficiency, large ratio range and low influence by load.

Cylindrical gear reducer is produced by carburizing, quenching and grinding, etc. It has high load carrying capacity and low noise level, so it is commonly used in mechanical conveying and also used in the transmission mechanism of other general machinery. It has the advantages of high load carrying capacity, long life, small size, high efficiency and light quality. The classification of gears mainly includes helical, straight and herringbone teeth. Straight gears are mainly used in the field of low speed and low load transmission; helical gears are often used in automobile reducers because they can have relatively high transmission speed. After comprehensive consideration, this paper selects helical gear as the main transmission gear of this reducer.
