Simulation grinding manner and worm grinding system of worm

摘要

PPROBLEM TO BE SOLVED: To provide the optimum grinding method by performing simulation analysis of tooth contact of a worm gear, which provides preferable tooth contact without performing a tooth contact inspection several times when grinding the worm gear which is engaged with a worm wheel processed by a gear hobbing machine. PSOLUTION: The shape dimension of the hob of the gear hobbing machine is measured, the shape dimension of a virtual worm wheel cut by the hob and the shape dimension of the virtual worm ground by the worm grinding stone formed in accordance with the basic data are combined to be displayed in a display unit of a computer in two or three dimension. In the above figure, the virtual worm and the virtual worm wheel are rotated on an its rotating shaft, respectively, to find the grinding conditions of the virtual worm by the hob, which provides the optimum tooth contact between the virtual worm and the virtual worm wheel, and grinding and finishing the worm roughly cut and formed by a tapping lathe, with the gear hobbing machine according to the thus found grinding conditions.
