Tips: How to reduce the noise of worm gearbox?
- Use smooth tooth surface. Grinding, rubbing and stone grinding can achieve ideal tooth surface roughness, or warming up in oil for a period of time can also improve the tooth surface roughness, which reduces the noise of the worm gearbox.
- Choose gears with good precision. If the pitch error, tooth profile error, tooth groove deviation and tooth rib error are reduced, the noise will be reduced. Grinding the tooth surface can not only improve the accuracy of the gear, but also improve the roughness of the tooth surface. Therefore, the noise of the worm gearbox reducer can be well reduced.
- Correct tooth surface contact. The implementation of tooth surface drum processing or cutting end processing to prevent single-piece contact, the noise will naturally be reduced. Proper tooth shape trimming is also effective in reducing noise.
The 40mm D.C. worm gearbox has a large output torque of 17 N.m and a reduction ratio of 5:1, 10:1... 80:1, 100:1. 2087 N.m maximum torque, 47 rpm rated speed, IP65. It can be used with asynchronous motors, AC motors, stepper motors, brushless motors, etc. The standard equipped 120W-370W asynchronous motors are also sold at a low price on ATO.
