Abstract
This invention aims to provide a method of lapping a bevel gear effectively by placing a gear-shaped tool whose axis has the same relation with the axis of the bevel gear as those of hypoid gears. In a double mode, gear-shaped tools are placed whose axes lie in a position offset with respect to the axes of the first gear and the second gear and have the same relation as those of hypoid gears. The first gear is engaged with one gear-shaped tool and the second gear is engaged with the other gear-shaped tool, while lapping liquid is supplied to engaging portions, thereby lapping engaging surfaces of toothed portions of the first gear and the second gear.
