Title:
ねじ状研削ホイール及びその目立て方法
Document Type and Number:
Japanese Patent JP4451564
Kind Code:
B2
Abstract:
A method of dressing a threaded grinding wheel such that twisting of workpiece tooth flanks does not occur during grinding. The grinding wheel is preferably dressed with a circular arc hollow-crowned generating front with the generating front being described by a radius, Rb, and dressed into an axial plane of the grinding wheel. The workpiece is then relatively shifted across the grinding wheel along a feed shift vector which is oriented perpendicular to the axis of the workpiece. With this method, the effects of flank twist can be eliminated, or, a controlled amount of flank twist can be introduced not only in helical gears, but also in spur gears. The grinding wheel may also be dressed with a circular arc barrel-shaped generating front. The principles of the present invention may also be applied to hobbing tools.
