Title:
歯車とその製造方法
Document Type and Number:
Japanese Patent JP7330427
Kind Code:
B2
Abstract:
In order to prevent a spalling failure of a tooth flank (10Y) at a middle point of a tooth height and a dedendum (10Z) caused by Trochoidal interference due to meshing during operation of a gear transmission, in a gear manufacturing process, a manufacturing method is adopted in which a tooth tip edge part is softened more than the tooth flank at the middle point of the tooth height and the dedendum by performing a tempering or annealing treatment on the tooth tip edge part (10X), more preferably by a local tempering or annealing treatment. As a result, it is possible to dramatically improve ease of manufacturing control, quality control, and safety control of a gear while preventing breakage of the gear.
