Title:
GEAR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/123715
Kind Code:
A1
Abstract:
In order to prevent separation damage of a tooth base surface (10Z) caused by trochoid interference, or damage of a tooth surface (10Y) of a tooth-height center portion caused by meshing during operation of a gear device, this manufacturing method for a gear has employed a tempering or annealing process on a tooth-tip edge portion (10X), or more preferably, a local tempering or annealing process, to soften the tooth-tip edge portion more than the tooth surface of the tooth-height center portion and the tooth base surface. As a result, the easiness in a gear manufacturing management, quality control, and safety management has been dramatically improved, while preventing damage to gears.
