This mainly depends on the gears used in what machinery and the hardness of the gear itself. If the accuracy of the gear itself is 7 or more and grinding is the finishing method, it is necessary to consider the small letter tolerance group, usually base section or tooth profile and other problems, first measure base section, such as base section need to pass through the improvement Tooth surface roughness to noise reduction; if the hobbing for the finishing method, the best plus grinding can be resolved. In addition, the parallelism of the two bearing holes can also cause tooth contact to produce noise.
