Abstract

The invention discloses a speed reducer which comprises a double-rotor motor. The inner rotor and the outer rotor of the double-rotor motor are matched and connected with a Simpson planet gear structure, and the Simpson planet gear structure comprises an outer gear ring. A sun wheel is arranged in the middle of the outer gear ring, four planet wheels are uniformly distributed between the sun wheel and the outer gear ring, and the planet wheels are meshed with the outer gear ring and the sun wheel. Any two of the outer gear ring, the planet wheels and the sun wheel are used as input ends respectively connected with the inner rotor and the outer rotor, and the last one is used as an output end connected with an output shaft. The speed reducer can realize high transmission ratio and multiple transmission ratios.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a reducer with a large transmission ratio. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. The reducer can be divided into two categories: general reducer and special reducer according to the purpose. The design, manufacture and use characteristics of the two are different. The reducer is used to reduce the speed and increase the torque to meet the needs of the work. In some occasions, it is also used to increase the speed. It is called a speed increaser. When selecting a reducer, it should be based on the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, compare the outer dimensions, transmission efficiency, carrying capacity, quality, price, etc. of differ...
