Abstract

See full text

An internal gear machining method and an internal gear machining device, are provided for grinding of a tooth profile of an internal gear using a barrel-shaped threaded grinding wheel. An NC device functions as a tooth profile error correction means and reduces a measured pressure angle error of a workpiece at a tooth face by correcting the radial position, the lateral position of the grinding wheel, the turning angle of the grinding wheel, and the helical motion; reduces a measured error in the direction of a tooth trace of the workpiece at a tooth face by correcting the helical motion; and reduces a measured tooth thickness error of the workpiece at a tooth face by correcting the radial position, the lateral position of the grinding wheel, and the helical motion.
