The micro reducer is a device composed of a motor and a reduction gear box. It is a mechanical device that can reduce speed and increase torque. There are also many names, such as reduction motor, gear reducer, reduction motor, etc.
In addition to many names, there are many kinds of miniature reducers. Generally speaking, helical gear reducers include parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, planetary gear reducers, cycloidal pin gear reducers, worm gear reducers, planetary friction mechanical stepless transmissions, etc.
The reducer is generally used for transmission devices with low speed and high torque. The engine, internal combustion engine or other high-speed working power is used to engage the big gear on the gear output shaft with a small number of teeth on the reducer input shaft. For the purpose of reducing speed, ordinary reducers also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth in the big and small gears is the transmission ratio.
Micro reducer
1. It can be divided into micro DC reducer and micro AC reducer according to current.
2. Divided by voltage: there are high-voltage miniature reducer and low-voltage miniature reducer.
3. According to the shape, it can be divided into planetary gear reducers, which are round in shape; The other is spur gear reducer with parallel shaft, which is non-circular in shape.
4. According to the size, there are large reducers and small reducers or mini reducers.
5. According to the transmission gear, it can be divided into: cylindrical gear reducer, worm gear reducer, harmonic reducer, bevel gear reducer, cycloidal gear reducer, and stepless speed reducer.
When selecting the reducer, the load, installation size, speed, power, noise, accuracy and working conditions shall be considered. If it is used in massagers, electric curtains, sweeping robots and other products, it must be a miniature reducer.
