Why does our gear motors have noise?
12v geared motors are used in home automation transmission, industrial intelligent transmission, and automotive transmission.Geared motors are an important part of the application in mechanical transmission.When a pair of gears are meshed, due to the inaccuracy of the pitch, the tooth shape, etc., corresponding noise is generated during the operation, and friction noise occurs between the tooth surfaces due to relative sliding.
As geared motor is the basic part of gear box transmission, it is necessary to reduce gear noise to control gear motor noise.12v geared motor is no exception.
Generally speaking, the main causes of gear system noise are as follows:
1.Gear of 12v geared motor design is improper. Parameter selection is  Improper, coincidence is too small , improper or no shape modification, and unreasonable gearbox structure. In the gear processing, the base section error and the tooth profile error are too large, the flank clearance is too large, and the surface roughness is too large.
2.Gear train and gearbox. low contact accuracy, poor parallelism of the shaft, insufficient rigidity of the shaft, bearing and support, and the rotation accuracy of the bearing is not as good as the gap. These problems can make your 12v geared motors have noise.
3.Other aspects-input torque,Load torque fluctuation, torsional vibration of shafting, balance of motor and other transmission pairs, etc. You can check  whether these aspects of the 12v geared motors are nomal.
The above is the reason about 12v geared motors i know from my teachers and learn from internet.if this page is helpful for you, we will be very happy.
