ZS cylindrical gear reducer

The ZS cylindrical gear reducer is made of environmentally friendly low-carbon alloy steel,which can reduce noise and vibration.However,sometimes noise still occurs during use,and there are different treatment methods for different types of noise.Many operators need to pay attention to the fact that the working tooth surface hardness of small gears is slightly higher than that of large gears.The noise reduction function of its ZS cylindrical gear reducer includes:

1.On the premise of meeting the bending fatigue strength,when the center distance of the ZS cylindrical gear reducer is constant,a larger number of teeth should be selected to improve the coincidence degree,ensure smooth transmission,and reduce noise.

2.When the structure allows,the use of helical gears should be given priority,as their vibration and noise are greatly reduced compared to spur gears.Generally,the helix angle should be selected between 8℃and 20℃.
3.Within the economic capacity of users,the precision level of hard tooth gears should be designed to be as high as possible.High precision gears produce much less noise than low precision gears.
4.On the premise of meeting the transmission requirements,the number of teeth of the large and small gears should be made mutually proportional as much as possible,in order to disperse and eliminate the influence of gear manufacturing errors on the transmission,and also to avoid periodic meshing of a certain tooth on the large and small gears,thereby making the transmission smooth and reducing noise.
5.In order to reduce the noise of ZS cylindrical gear reducer,when selecting the backlash,if the transmission is pulsating rotation,a smaller backlash should be chosen.
The noise reduction function of ZS cylindrical gear reducer is believed to be helpful to everyone after understanding it.That's all for the above knowledge.
