How to make DC gear motor noise lower?

DC motor can meet both requirements of linear movement and high torque, which decides it can be
widely used in smart devices, robotics, office, home appliance, machinery, medical, chemistry,
agriculture and other fields. Shanghai Meichu has been focus on supplying with high quality DC
motor with various gear boxes such as spur gear, bevel gear, helical gear, planetary gear, worm
gear etc.. to meet various customized requirements.
About DC gear motor, one important issue most clients are concerned about is noise. The better the
motor is more welcome the lower the noise is. Shanghai Meichu has rich experience in controlling
noise and we’d like to share some noise-reduction method with you. We can use famous branded
damping grease like Mobile. We can also improve the fit, accuracy, material, tooth profile, etc.
between gears to make noise lower. Different types of gears can reach different noise leve. For
example, worm gear can normally reach smallest noise without size restriction. Planetary gear
used for high speed part needs nylon gears with good noise reduction effect and suitable
lubricating oil to reach lower noise. We can also choose materials that ensure strength and
processes such as adjusting the clearance of gear meshing, as well as using precision rolling and
hard rolling to improve the smoothness of gear tooth surfaces, in order to improve and control
noise. Sometimes if we add a shock-absorbing pads between the motor and gearbox can also work
for lower noise.
Anyway, noise of DC gear motor has many methods to control noise but different gear motor
application environment needs special treatment of noise control, it needs both buyer and vendors
of DC motors to discuss before reach best resolution.
