<P>PROBLEM TO BE SOLVED: To provide a dressing gear for allowing easy confirmation of a replacing time for the dressing gear due to damage to the tooth tip part and the reuse with the re-electrodeposition of abrasive grains even when continuous dressing without finding the fall-off of the abrasive grains causes damage to base metal areas at both ends of the tooth tip part of the gear body where loads are concentrated, in particular. <P>SOLUTION: The dressing gear includes the gear type gear body 1 having a plurality of teeth formed on the outer periphery, and an abrasive grain layer 5 is formed on the surfaces of the teeth. The plurality of teeth include a replacement index tooth 3A at least tooth-trace-direction both ends 6A of which have larger outer diameters. <P>COPYRIGHT: (C)2013,JPO&INPIT |
