When the gear hobbing machine, gear hobbing cutting depth increases, the cutter shaft transmission box a gala Gala of the strange sound, returned from the new start roll disappears, each gear case, open the inspection found no gear hob shaft breakage, pressure bearing clearance, from the new installation and debugging after the situation remains the same, this is what's the matter?

The gear grinder is out of order and the gap is a bit too big
The pressure has increased
