On the machining of curved tooth bevel gears: Determination of set up conditions

Abstract Machining curved tooth bevel gears is one of many problems in metal cutting. Even though the initial approximate setting values for the vertical and horizontal offset of the cutter center relative to the cradle center are easily obtained, the final setting often proves difficult. Many times the final setting is left to the operator's skill in manipulating the bevel gear generator required to obtain correct bearing contact between mating gear and pinion. Bevel gear machining is thus a science as well as an art. The objective of this paper is to present existing literature in a simplified manner so as to be utility to the manufacturer. A case study of Crown Wheel and Pinion has been taken up for illustrative purposes for the calculation of setting parameters.
