The reducer is a relatively precise machine, whose function is to reduce speed and increase torque. It has a wide variety of models, and different types have different uses. According to the transmission type, it can be divided into gear reducer, worm reducer and planetary gear reducer; According to different transmission stages, it can be divided into single-stage and multi-stage reducers; According to the shape of gear, it can be divided into cylindrical gear reducer, bevel gear reducer and bevel - cylindrical gear reducer; According to the layout of the transmission, it can be divided into deployable, split and coaxial reducers.
The structure of a planetary reducer includes: connecting plate, coupling, lower cover plate, sun gear, planetary gear, inner gear ring, upper cover plate, and planetary bogie.
1) Coupling: transfer the power of the motor to the reducer.
2) Upper cover plate and inner gear ring group: they are important parts for planetary reducer operation.
3) Planetary gear: it is an important transmission part of planetary reducer, which can be divided into straight teeth and helical teeth.
4) Planetary turret: the planet wheel fixed frame and the turret are designed and formed in an integrated way. The planet carrier can be divided into single support and double support. The planet gear reducer with single support is economical, and the planet gear reducer with double support is cage-type planet carrier.
5) Connecting plate: connecting motor and reducer, which can be perfectly matched with servo motor and stepper motor of various brands.
Role of planetary reducer
1. Increase the torque, the planetary reducer can enlarge the torque of the motor, and the motor with smaller power can be selected to realize the output of large torque.
2. The variable speed function of the planetary reducer can convert the high speed of the motor into the low speed required by the equipment, and the reduction ratio is an accurate positive integer.
3. Precise positioning. After the planetary reducer is also a servo motor combination, the precise positioning, quantitative feeding, angle measurement and other functions of the equipment can be realized through pulse control.
