Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer with a dual-power structure. Background Art

[0002] A reducer is a power transmission mechanism that uses a gear or worm gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Its applications range from large power transmission to small loads and precise angle transmission. In industrial applications, reducers have the functions of reducing speed and increasing torque. Therefore, they are widely used in speed and torque conversion equipment.

[0003] However, in actual use, traditional reducers usually have only one output end, that is, all components in the reducer only drive and work on one output shaft. When the torque kinetic energy of a reducer is small, another reducer needs to be installed and used in conjunction with assembly equipment. This is not only inconvenient to install, but also increases production costs. It is inconvenient to arbitrarily adjust whether dual power is needed, resulting in poor flexibility. Therefore, a reducer with a dual-power structure is proposed. Utility Model Content
