Claims

[Scope of utility model registration request]

In a gear grinding machine, the grinding wheel has a grinding surface on the outer periphery and a tapered hole in the center, and the tapered hole is fitted into a tapered shaft portion protruding from the end face of a rotating shaft. A plurality of grinding surface correction mechanisms are arranged circumferentially around the hole, and this grinding surface correction mechanism includes a differential screw having first and second male threads of different pitches, and a differential screw having first and second male threads of different pitches. The first male threaded portion of the differential screw is screwed into the lock nut fixed to the grinding wheel side, and the second male threaded portion of the differential screw is screwed into the lock nut, and the differential screw is rotated. A grindstone grinding surface correction mechanism for a gear grinding machine, comprising an adjuster rod that moves in and out of the end face of the rotating shaft by the pitch difference of the male screw part.
