Device capable of increasing output torque of speed reducer

Abstract

The invention belongs to the technical field of speed reducers and particularly discloses a device capable of increasing the output torque of a speed reducer. The device comprises an output gear, a torque increasing gear, a supporting gear and a transmission gear; both the output gear and the supporting gear are respectively and fixedly mounted; the torque increasing gear is erected between the output gear and the supporting gear and is respectively meshed with the output gear and the supporting gear from the left side and the right side; the transmission gear is connected with the speed reducer on one hand and is meshed with the torque increasing gear on the other hand; the torque increasing gear is horizontally-placed cylindrical gear, and a counterweight is connected with the bottom ina cylinder and is in sliding connection with the bottom of the cylinder through a very small friction force. As the torque increasing gear is arranged between the output gear and the supporting gear,and the counterweight is arranged in the torque increasing gear, the counterweight provides always downward torque, so that the output torque of the output gear is increased. Therefore, the effect ofincreasing the output torque can be realized without increasing the power of the speed reducer.

Description

technical field [0001] The invention belongs to the technical field of reducers, and in particular relates to a device capable of increasing the output torque of a reducer. Background technique [0002] Torque is a special moment that makes an object rotate. The torque of the engine refers to the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range. The external torque is called torque or external couple moment, and the internal torque is called internal couple moment or torque. [0003] In many working conditions, there is a realistic and urgent demand for large output torque. Existing reducers still have deficiencies in providing large torque output. Generally, the size of the torque is adjusted by adjusting its own speed, and is limited by the power of the redu...

Problems solved by technology

The existing reducer is still insufficient in providing large torque output. Generally, the size of the torque is adjusted by adjusting its own speed, and is limited by the power of the reducer, so the adjustment range is narrow and the limitation is large.
