automatic grinding machine
Multi-blade saw gear grinding machine to reduce machine noise
should take the following measures:
1,Gear parts that have a greater impact on noise (focusing on
several pairs of high-speed transmission gears Z 45/ Z 20, Z 26/ Z
60, etc.) are modified and some weight reduction holes are made to
make the tooth shape curve of the gear teeth convex and reduce the
sound propagation area. Experiments show that gear noise is mainly
caused by end-face radiation. The larger the surface area, the
larger the radiated noise value. The drilling can reduce the
radiated area of noise, so the noise reduction effect can be
achieved.
2,When machining gears, controlling the base of the pinion to make
it slightly larger than the base of the big gear can reduce noise.
Because the base of the pinion is slightly reduced due to the
deformation of the force when meshing. This can be controlled by
sharpening the hob front Angle, usually increasing the hob front
Angle of the hob cutting pinion.
3,Machine tool noise is a system engineering caused by many
factors, and gear noise is only one of them. Gear accuracy is also
an aspect of causing gear noise, other factors such as motors,
shafts, bearings, boxes, etc., are factors that can not be ignored.
At present, the research is continuing to make the noise of the
milling machine stable at 81d B (A) level to meet the export level
requirements.
