[0002] A reducer is a mechanical transmission device widely used in industrial machinery and automation equipment to reduce the speed of the motor output shaft and increase the torque. The transmission ratio is a key parameter of the reducer. It indicates the speed ratio between the input shaft and the output shaft, usually expressed in numbers. For example, 10:1 means that the speed of the output shaft is one tenth of the input shaft. The transmission ratio determines the output torque and output speed of the reducer. A reducer usually contains a set of gears for transmitting power and achieving a deceleration effect. Gears can be divided into different types, such as worm gears, bevel gears, spiral gears, etc. Each type is suitable for different applications. The reducer has an input shaft, which is usually connected to the motor to receive power, and an output shaft for outputting the reduced speed and increased torque.
