Title: Gear grinding method
Inventor: FUKUMOTO HIROSHI
IPC: B23F5/06
Filed: 1987-12-11
Abstract: PURPOSE:To carry out grinding with high precision by the gear grinding method consisting of cutting-in zero grinding, gear grinding method consisting of dividing grinding, and a rough grinding process and finishing grinding process. CONSTITUTION:The number of times of intermediate zero grinding, number of times of rough final zero grinding, and the number of times of finishing grinding are set into the setting parts 31-33, and when the dividing grinding is carried out, the number of teeth corresponding to the starting point of the unit process is set into a setting part 34. In the rough grinding process, grinding is carried out at an ordinary grinding feed speed. Since the cut-in quantity is set to zero in the intermediate zero grinding and the final zero grinding, each deflection of the grindstones 21 and 22 is nearly zero, and grinding is carried out in the state where the chattering due to the elastic vibration of the grindstones 21 and 22 is nearly zero. Since the starting point of the unit process is deflected in the dividing grinding, the backlash of the rotary mechanism of a gear 1 and the influence due to the delicate tendency of a grinding machine or grindstone dresser are dispersed and diluted onto each gear surface of the gear 1. The finishing grinding is carried out at a low grinding feed speed, and the deflection of the supporting shaft for the grindstones 21 and 22 is reduced and the chattering due to the elastic vibration can be reduced.
