The design and production system of the conical involute gear is developed. This system is composed of gear cutting method, gear grinding method, over-ball measurement for control of finishing dimensions, tooth surface measurement, tooth surface analysis, tooth action and normal allowable load between two mating gears, and the design of a pair of gears. As a result, the conical involute gears came to be used in a wide range of applications. This paper presents the research and development of the conical involute gears for more than 25 years, many applications, and a new possibility for tomorrow.
