Working principle of reducer.
Reducer is a relatively precise machine.
The purpose of using it is to reduce the speed and increase the torque.
Speed ratio = motor output revolution ÷ reducer output revolution.
According to the motor power, speed ratio and service coefficient, the reducer torque is calculated as follows: reducer torque = 9550 × Motor power ÷ motor power input revolutions × speed ratio × Service factor.
Torque and the output revolutions and service coefficient of the reducer, the motor power required for the reducer is calculated as follows: motor power = torque ÷ 9550 × Motor power input revolutions ÷ speed ratio ÷ service factor.
It has a wide variety, different models and different uses.
There are many kinds of reducers, which can be divided into gear reducer, worm reducer and planetary gear reducer according to the transmission type.
According to different transmission stages, it can be divided into single-stage and multi-stage reducers.
According to the gear shape, it can be divided into cylindrical gear reducer, conical gear reducer and conical cylindrical gear reducer.
According to the arrangement of transmission, it can be divided into deployable, shunt and coaxial reducers.
The following are the commonly used reducer categories: 1.
Cycloidal reducer 2.
Hard tooth cylindrical gear reducer 3.
Planetary gear reducer (currently used in the workshop): fixed ring gear, sun gear active and planet carrier passive.
It can be seen from the demonstration that this combination is speed reduction transmission, the transmission ratio is generally 2.
5 ~ 5, and the steering is the same. 4. Soft tooth surface reducer 5, three ring reducer 6, crane reducer 7, worm reducer 8, shaft mounted hard tooth surface reducer 9, CVT worm gear reducer is mainly characterized by reverse self-locking function and large reduction ratio, The input shaft and output shaft are not on the same axis or plane.
However, the general volume is large, the transmission efficiency is not high, and the accuracy is not high.
The harmonic drive of harmonic reducer uses the controllable elastic deformation of flexible elements to transmit motion and power.
It has small volume and high precision, but its disadvantages are that the flexible wheel has limited service life, is not resistant to impact, has poor rigidity compared with metal parts, and the input speed can not be too high.
Planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life, large rated output torque, but the price is slightly expensive.
