Abstract
Provided is a gear matching device which performs gear matching to establish a rotational phase relationship between a grindstone () and a gear-shaped workpiece (W) in which the grindstone and the workpiece can mesh with each other, before gear machining is performed by causing the grindstone and the workpiece to mesh with each other, and by then relatively rotating the grindstone and the workpiece, the gear matching device including: a tail stock () which is supported to be movable in the axial direction of the workpiece, and by which the workpiece is pressed against a rotary table () to be rotatably held, the rotary table rotating the workpiece about the axis thereof; and a sensor () which is provided to the tail stock, and which faces the workpiece to detect the rotational phase thereof, when the tail stock holds the workpiece.
