Design of Miter Conical Involute Gears Based on Tooth Bearing

Abstract

Miter gears are the most often used of all bevel gears. Now that cutting and grinding methods of conical involute gears with a cone angle of 45 degrees have been established, miter conical involute gears may become the most useful of conical involute gears. However, in the former design of the miter conical involute gear, tooth bearing has not been taken into consideration ; thus, the desired tooth bearing has not been obtained. In this study, first a new design for miter conical involute gears is developed, making it possible to locate the tooth bearing at the central part of the tooth width. Second, test gears are designed and made. Finally, tooth bearing tests are performed, and the design applicability is proven.
