Generation of a crowned pinion tooth surface by a plane

Abstract : The topology of a crowned spur pinion tooth surface that reduces the level of transmission errors due to misalignment is described. The geometry of the modified pinion tooth surface and of the regular involute gear tooth surface is discussed. The tooth contact analysis between the meshing surfaces is also described. Generating a modified pinion tooth surface by a plane whose motion is controlled by a 5-degree-of-freedom system is investigated. The included numerical results indicate that the transmission error remains low as the gears are misaligned. Transmission mechanical, Wear resistance.
