(English) Zbl 0979.74053 Comput. Methods Appl. Mech. Eng. 188, No. 1-3, 363-390 (2000). Summary: An asymmetric spur gear drive is considered. The asymmetry means that larger and smaller pressure angles are applied on driving and coast sides, respectively. The conventional design of such a drive is based on the application of involute profiles. We propose a modified geometry of an asymmetric spur gear drive, designed as a combination of an involute gear and a double crowned pinion that enables to localize and stabilize the bearing contact and to obtain a favorable shape of transmission errors of reduced magnitude. We develop the computerized design of spur gears of proposed geometry, and perform the simulation of their meshing and contact. A method of generation of a double-crowned pinion has been developed together with the stress analysis of symmetric and asymmetric spur gears, that confirms reduction of contact and bending stresses for an asymmetric spur gear drive. The theory is illustrated with numerical examples.
