Gear reducer is generally used for transmission equipment with low speed and large torque. The ratio of the number of teeth of big and small gears is the transmission ratio. With the continuous development of the reducer industry, more and more enterprises have applied the reducer.

The gear reducer can be used in a variety of harsh environments with high reliability. Because it can be mass produced, it is cheaper than other similar products in terms of price, which is one of the reasons why many users choose this equipment.

The gear reducer is an independent component composed of gear transmission, worm transmission and gear worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuating mechanism. It is a relatively precise machine, with the purpose of reducing speed, and is widely used in modern machinery.

① Gear reducers can be divided into cylindrical gear reducers, bevel gear reducers and bevel and cylindrical tooth inducer reducers according to the gear shape.

② According to different transmission stages, it can be divided into single-stage and multi-stage reducers.

③ According to the arrangement form of transmission, it can be divided into spread type, split type and shaft type reducers.

The size and specifications of gear reducer are complete. Only after understanding its working principle, scope of application and parameters, can it be more convenient to use and improve its service life.
