1. Gear reducer can be divided into gear reducer according to the type of transmission system. Worm gear reducer and planetary gear reducer.
2. Single-pole and multi-level reducers can be categorized into different types of drive train classes.
3. Based on the shape of the gears can be divided into cylindrical gear reducers . Bevel gear reducer and bevel gear reducer
4. According to the planning of the transmission system, it can be divided into unfolding type. Separate type and the same tooth embedded reducer. Reducer is a closed in the rigidity of the transmission gear drive. Worm gear transmission. By the transmission gear-worm gear transmission constitutes an independent component is generally used as a speed reduction transmission system between the prime mover and the working machine.
In modern machinery, it is widely used to match speed and transmit torque between the transmission, working machine or actuator. Reducer is generally used for low-speed gear high torque motor equipment, electric motors . Gas turbine or other high-speed operation drive according to the reducer input shaft gear module smaller transmission gears and input shaft in the large gear bite, to do the effect of speed reduction. General reducer also has several sets of transmission gears with the same basic principle, so as to achieve the most ideal speed reduction effect. Transmission gear size gear module ratio gear ratio.
The German Simag reducer has planetary gear reducer, worm gear reducer, general motor, etc.
