Development of a Grinding System for Sharpening the Cutter of Gear Shape and Evaluation of its Performance. 2nd Report. Construction of Gear Tooth Grinder and Examination of its Principle.

Abstract

A grinding machine for involute helical gears is constructed that can generate arbitrarily three-dimensionally corrected tooth flank forms by using a grinding disc without transverse movement. Basic structures such as the coordinate system and the axes of the grinding machine are designed and a new antibacklash speed reducer using involute worm gears is invented to raise the Computer Numerical Control (CNC) performance for synchronous action between the axes for generating tooth flanks. An integrated procedure of action of the computer to simulate the tooth flank form to be generated and that of the actual grinding machine is proposed. This grinding system shows a good performance for achieving the intended three-dimensionally corrected tooth flank form.
