Power and Strength Calculations of Wave Gear with Ball Intermediate Bodies

Lazurkevich A.V., Aliev F.R., An I.

Abstract


Wave planetary gears with ball intermediate bodies are simpler and more technological than similar gears with roller intermediate bodies. Now such gears find broad application in various industries: oil, mountain, aviation, space and other. However, now there are no general methods for geometrical, power and strength calculations of gears with the difference between tooth numbers for a gearwheel and balls, equal to ±1. This task is important not only within the strength analysis of meshing elements and support units but also at gear design as the direction of rotation of the driven element changes to the opposite one. In this paper, the original method for power and strength analysis of the wave gear with ball intermediate bodies based on the solution of a problem of static indetermination with application of contact tasks is considered. Some difficulties of the task are connected with solutions of systems of transcendental equations, and with calculation of curvature of tooth profiles. In this regard, the program for the personal computer in the environment of Delphi has been developed for numerical implementation of the task. At the same time the radius of curvature of tooth profiles for the gearwheel is determined using chords between three points on the profile and the theorem of sines.
