[0002] Gear motors are often used in industrial production because reducers play an important role in transmission equipment. There are also many types of reducers, which are basically divided into two categories: right-angle shaft reducers and parallel shaft reducers. Right-angle shaft reducers and parallel shaft reducers have their own characteristics to facilitate the application of different working environments. The characteristic of the right-angle shaft reducer is that the motor input shaft and the reducer output shaft are at a right angle of 90 degrees. The output direction can be changed while reducing speed, so it is called a right-angle shaft reducer.
[0003] However, the existing small-sized right-angle shaft reduction motors cannot replace the gears for meshing reduction, which results in almost the same value of torque increase when the speed is reduced under the same model. As a result, different models of right-angle shaft reduction motors must be replaced when different speeds need to be reduced, thereby increasing production costs.
