How to reduce the noise when precision machinery parts processing?

Precision machinery parts processing when will have the presence of the noise and the noise will not only interfere with the normal work of the relevant personnel, but also a kind of pollution. So how to reduce the noise when precision machinery parts processing? Below small make up to tell you! 1, civilized production: gear transmission noise has more than 30% of the causes from the burr, knock against injury. Some precision machinery parts processing factory in front of the gear box assembly, remove burrs and knocked wounded, is a passive way. 2, ensure the accuracy of gear blank: the precision requirement of the size of the gear hole in the middle of the hole deviation difference about distribution, plus or minus 0. 003~±0. 005mm; If the out-of-tolerance and within the scope of the hole design requirements, must be classified, respectively into gear cutting process. 3, the control precision of the gear, gear accuracy of basic requirements: it has been verified by practice that must be controlled in GB10995 - gear precision 887-8, linear velocity is higher than the 20 m/s gear, pitch limit deviation, ring gear tooth to radial run-out tolerance, tolerance must be stable accuracy reached level 7. Above is to reduce the precision machinery parts processing method of noise, hope can help to you!
