Abstract
Provided are: a screw-shaped grindstone for grinding gears that has a simple configuration and is capable of grinding gears with high precision; and a method for grinding gears. The screw-shaped grindstone (20) for grinding gears, which grinds a workpiece (W1) by rotating while meshing with the workpiece (W1), comprises a screw-shaped grindstone (21) that grinds the workpiece (W1), and a screw-shaped grindstone (22) that is linked to the screw-shaped grindstone (21) on the same axis, and grinds the workpiece (W1), which has been ground by the screw-shaped grindstone (21). A plurality of grinding ranges (L1, L2) that are sectioned at prescribed lengths in the width direction of the grindstone are established with respect to the screw-shaped grindstones (21, 22), and each grinding range (L1, L2) of the screw-shaped grindstones (21, 22) serves as the range of use per workpiece (W1).
