Abstract
Provided are a gear machining apparatus and a gear machining method with which the surface roughness, in a tooth profile evaluation range, of the surfaces of the teeth of a gear can be improved. This gear machining apparatus (1) machines shapes a gear (4) by machining a workpiece (4) with a grinding wheel, and comprises: a threaded grinding wheel (32) that shapes a gear (4) by machining a workpiece (4); and a disc-shaped dresser (36) that shapes the threaded grinding wheel (32) while rotating with the threaded grinding wheel (32) in a meshed state. A pressure angle (a) of the dresser (36) is designed to be dislocated such that a reference pitch circle diameter (PCD) of the gear (4) shaped by the threaded grinding wheel (32) is outside the tooth profile evaluation range of a tooth surface (5).
