The main causes of noise in the gear system are as follows:
(1) The gear design parameters are improperly selected, the overlap is too small, the tooth profile is improperly modified or not modified, the gear box structure is unreasonable, etc.
(2) gear processing base pitch error and tooth profile error is too large, tooth side clearance is too large, surface roughness is too large.
(3) The assembly of the gear train and gear box is eccentric, the contact accuracy is low, the parallelism of the shaft is poor, the rigidity of the shaft, bearing and support is insufficient, the rotation accuracy of the bearing is not high and the clearance is improper.
(4) other aspects of the input torque. The fluctuation of load torque, the torsional vibration of the shaft system, the balance of the motor and other transmission pairs, etc.
