How many kinds of reducers can be divided into?
Generally speaking, there should be three kinds of worm reducer, harmonic reducer, cycloidal pinwheel reducer and planetary reducer.The worm strength is maximum, but the efficiency is low, the precision is not high, but it has a self-locking function, can have a larger reduction ratio, large volume, the input speed is above 3000, the main characteristics of harmonic reducer is small. The accuracy is not high, not a limited life, impact resistance, rigidity and metal parts compared poor, the input speed is not too high, the input speed is below 2000, planetary reducer structure is compact, small backlash, high precision, long service life, rated output torque can be large, but the price is a little expensive. This is my experience in the industry. I wonder if it will help you.
3) planetary reducer has the advantages of compact structure, small return clearance, high accuracy and long service lifeThe output torque can be done a great deal. But the price is slightly expensive.
2) harmonic drive of harmonic reducer is to transfer the motion and power by means of elastic deformation controlled by flexible elementsSmall, high precision, but the disadvantage is that flexible wheel life is limited, not shock resistant, rigid and metal parts are relatively poor. Input turnSpeed can not be too high.
Types of common reducers1) the worm gear reducer's main characteristic is to have the reverse self-locking function, may have the bigger reduction ratio, the input shaft andThe output shaft is not on the same axis, nor on the same plane. But the general volume is large, the transmission efficiency is not high, the accuracyNot high.
