Motor gearbox to provide quality cheap, welcome the masses of friends to come to the choose and buy, can also custom design, gear box is an important part of a widely used in mechanical transmission, a pair of gear meshing, because there are inevitably, pitch and tooth profile error produces in the process of operation in the gear mesh frequency corresponding to the meshing impact and noise, noise due to the relative sliding friction between tooth surfaces.As the gear is the basic part of gearbox transmission, it is necessary to reduce the noise of gear box.Generally speaking, the causes of gear system noise mainly include the following aspects:
1. Gear design.Improper selection of parameters, too small overlap, improper or no modification of tooth profile, unreasonable gear box structure, etc.In gear processing, the errors of base and tooth shape are too large, the clearance of tooth side is too large, and the surface roughness is too large.
2. Gear system and gearbox.Eccentric assembly, low contact accuracy, poor parallelism of the shaft, insufficient stiffness of the shaft, bearing and bearing, low rotary precision of the bearing and improper clearance, etc.
3. Input torque in other aspects.Fluctuation of load torque, torsional vibration of shafting, balance of motor and other transmission pair, etc.
