Title: Tooth surface grinding method for helical bevel gear
Inventor: KITAHARA YOSHIMASA
IPC: B23F9/02
Filed: 1988-04-07
Abstract: PURPOSE:To prevent the occurrence of polishing burning by a method wherein control is made so that the inclination angle, the moving direction, and a moving amount of a grinding stone part situated to a rotary cutting tool are changed, and a tooth surface forming part is cut in a state that the grinding stone part is brought into point contact or line contact with the tooth surface forming part of a helical tooth bevel gear. CONSTITUTION:A rotary shaft member 14 is rotated togetherwith a rotary grinding tool 10 through running of a motor 38. The whole of a rotary part 22 is rotated based on a casingform support part 20 through running of a motor 28 in a state that a grinding stone part 12 is rotated around a main spindle extending through the central part of a body part 11 of the tool 10 surrounded with the grindings tone part 12, and an inclination angle based on the rotary shaft of the rotary part 22 is changed with the aid of the motor. Further, through the motion of an elevating cylinder 40, the length, protruded from a rotary shaft holding part 24, of the member 14 is changed to change a position where the grinding stone part 12 is separated away from a holding part 24. As a result, since the grinding stone part 12 grinds a tooth surface forming part 51 in a state that it is always brought into point contact or line contact with the tooth surface forming part 51 of a helical tooth bevel gear 50, deficiency in grinding cooling liquid is prevented from occurring.
