Abstract
A rotary dressing roller of the generating type and a method and apparatus for dressing a substantially cup-shaped grinding wheel for longitudinally curved tooth gears. The rotary dressing roller 40 is provided with a base portion 42 which is rotatable mounted to the dressing motor 38 of a dressing apparatus 15. The dressing apparatus 15 is used to dress a grinding wheel 50. At the other end of base portion 42 there is provided a working portion 44 having an outer concave surface 45, an inner convex surface 46 and an outer cutting rim portion 47. The outer concave surface 45 and inner convex surface 46 of working portion 44 are shaped so as to allow dressing of the inside working surface 52 and outside working surface 54 of grinding wheel 50 by rotation of the rotary dressing roller 40 in a single direction.
