INTERNAL GEAR-SHAPED DIAMOND DRESSER HAVING CLEARANCE, TRUING OF GRINDSTONE FOR GEAR MACHINING, DRESSING METHOD, AND GRINDING METHOD OF INTERNAL GEAR

摘要

PPROBLEM TO BE SOLVED: To provide an internal gear-shaped diamond dresser capable of truing and dressing highly accurately and highly efficiently a grindstone for use in highly accurately grinding an internal gear which has been tempered. PSOLUTION: The internal gear-shaped diamond dresser being designed by the almost same specification as that of the internal gear of a workpiece, having a tooth shape at an inner diameter part of a ring shaped metal substrate, and having a clearance at both ends of the tooth shape in a tooth width direction is used. The clearance is set by chamfering or providing a step. Preferably, module, pressure angle, torsion angle, tooth thickness and the like which are main specifications of the gear are each made to be the same as those of the workpiece. A tooth width and a tooth depth are designed to be larger than those of the workpiece to ensure meshing with the grindstone. The number of teeth is increased and decreased according to the specification of the diamond dresser. PCOPYRIGHT: (C)2010,JPO&INPIT
