When we operate large machines, the sound of the machine is generally relatively large, so that there will be noise, so that other staff, will also cause some trouble, precision machining is the same, so how to reduce the noise of precision mechanical parts processing? What are the treatment methods?
1, Civilized production.
Gear transmission noise has more than 30% of the reasons from the burr, bump injury. Some precision mechanical 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 is required to be distributed around the middle difference of the deviation value of the hole, set at ±0.003~±0.005mm; if the difference is exceeded but within the design requirements of the hole, it must be classified and transferred to the gear cutting process respectively.
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.
