Precision mechanical parts processing will inevitably have noise, 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 of precision mechanical parts processing? The following editor to tell you!
1. Civilized production.
Gear transmission noise has more than 30% of the reasons from the burr, bump injury. Some precision machinery parts processing factory in the gear box assembly before the removal of burrs and bump injuries, is a passive practice.
2, to ensure the accuracy of the tooth blank.
The accuracy of the size of the gear hole requirements in the hole deviation value of the middle difference around the distribution, set at ± 0.003 ~ ± 0.005mm; if the excess difference and within the design requirements of the hole, must be classified, respectively, transferred to the gear cutting process.
3、Control the accuracy of gears.
The basic requirements of gear accuracy: proven by practice, gear accuracy must be controlled in GB10995-887 ~ 8 levels, linear speed higher than 20m / s gear, tooth pitch limit deviation, tooth ring radial runout tolerance, tooth tolerance must be stable to 7 levels of accuracy.
