Description

Technical Field

[0001] The invention relates to a reduction motor, in particular to a front output overspeed ratio reduction large torque motor. Background Art

[0002] In the prior art, the combination of a reducer and a motor can achieve a certain range of speed change, which not only achieves the effect of speed change, but also does not affect the power of the motor, and the output shaft torque increases several to dozens of times.

[0003] In the prior art, the combination of a reducer and a motor is relatively common. In order to increase the torque, the reducer housing must be designed separately. This combination looks like a reducer, and the slip ratio is extremely large when changing speed, so a large speed ratio cannot be achieved.

[0004] The motors with reduction devices designed using the existing motor standards generally use planetary reduction mechanisms to cooperate with the motors, but most of them have the following shortcomings: A. The general reduction ratio is low, and can only be reduced by several times, which cannot meet the speed ratio requirements; B. Due to the limitations of the planetary reduction structure, the output torque does not meet the requirements; C. Affected by the planetary reduction structure, the structure is relatively complex and inconvenient to maintain. The planetary reduction structure adopts a concentric sleeve shaft method between the motor shaft and the power output shaft, which has high manufacturing costs and is easy to damage. At the same time, the use of the sleeve shaft method affects the large torque output of the motor shaft and the power output shaft. Summary of the invention
