(1) gear accuracy: if pitch error, tooth shape error, tooth groove deviation and tooth rib error are reduced, the noise of planetary gear reducer will decrease naturally. Grinding tooth surface, in addition to improve the internal accuracy of the gear, can also improve the tooth surface roughness. NEWGEAR super precision integrated series planetary gear reducer, simplified structure, reduced internal parts assembly, higher accuracy, good noise control effect.

(2) gear smoothness: grinding, rubbing and wheting-grinding can all reach the ideal tooth surface roughness. In addition, warm-up operation in oil for a period of time can also improve the tooth surface roughness, which can reduce the noise of planetary gear reducer. NEWGEAR planetary gear reducer imported gear selection with high precision, good finish, can effectively reduce the noise of planetary gear reducer.

(3) lubrication: high viscosity, shear stability, good low temperature performance and thermal oxidation stability, gear oil viscosity, the tooth surface suffered from a variety of damage to protect the ability of the stronger, mechanical wear is smaller, high viscosity lubricating oil on the planet gear reducer noise reduction is better. NEWGEAR planetary gear reducer is selected with imported lubricating oil, which is strictly controlled from purchase to application to ensure low noise.

(4) tooth surface contact: perform tooth surface drum processing or cutting end processing to prevent single piece contact and reduce noise. Proper gear modification is also effective in reducing the noise of planetary gear changes. To remove abrasions or scratches on the surface of teeth.

(5) rotation and backlash: pulsating rotation, small backlash is beneficial to reduce the noise of planetary gear reducer. Balanced load, gear gap slightly larger on the planet gear reducer noise reduction benefits.

(6) occlusal rate: the higher the occlusal rate, the lower the noise, and the reduction of pressure Angle or the increase of tooth depth can increase the occlusal rate. Higher overlap ratio also reduces noise, so helical gears are less noisy than spur gears.

(7) rigidity: high rigidity shape is good for reducing the noise of planetary gear reducer. Strengthen the rigidity of gearbox and shaft.

(8) material: light load and low rotation gear, plastic gear is a good choice, but pay attention to the temperature rise. Cast iron gears are more effective at noise reduction than steel gears.
