How to reduce the noise during precision parts processing?

1. Civilized production:

More than 30% of gear transmission noise is caused by burrs and bumps. Some precision machinery parts processing plants remove burrs and bumps before the gearbox is assembled, which is a passive approach.

2. 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 hole deviation value, set at ±0.003~±0.005mm; if it is out of tolerance and within the range of the hole design requirements, it must be classified and transferred to the gear cutting process.

3. The precision of the control gear:

The basic requirements of gear accuracy: verified by practice, the gear accuracy must be controlled at GB10995-887~8, the linear speed is higher than 20m/s gear, the pitch limit deviation, the radial runout tolerance of the gear ring, and the tooth direction tolerance must be stably achieved Level 7 accuracy.
