What is the structure of the reducer?

1.The main components of the reducer structure are: gear box, transmission motor, transmission shaft, output shaft.

1). Gear box: composed of gear set, transmission shaft, box body and washer.

2). Gear stages: The reducer has single stage, double stage, and third stage, but some of the large reduction ratios can reach four stages. The larger the stage number, the lower the reduction transmission efficiency.

3). Transmission motor: The reducer can use with DC brush motor, DC brushless motor, stepper motor, hollow cup motor, motor, permanent magnet motor .

4). Drive shaft: sintered bearing, rolling bearing.

5). Output shaft: metal output shaft and plastic output shaft.

2.The role of a reducer:

1). The reducer is installed between the prime mover and the working machine to reduce the speed and increase the torque. It is widely used in production. Common gear reducers, worm gear reducers, etc. The components of this survey are first-level Cylindrical gear reducer.

2). The reducer converts the higher speed to a lower speed.

Since the gear teeth of the input gear shaft mesh with the large gear on the output shaft, and the number of gear teeth of the input gear shaft is less than that of the large gear on the output shaft, the gear ratio is inversely proportional to the speed ratio. When the power source(like motor) or high-speed motion of other transmission mechanisms, after being transmitted to the output shaft through the input gear shaft, the output shaft will get a low-speed motion lower than the input shaft, so as to achieve the purpose of deceleration. Although the shape of the reducer is various, the basic structure is composed of shafting parts, box and accessories.
