Stress Analysis in Double Enveloping Worm Gears by Finite Element Method

Abstract

A method and a corresponding computer program are developed for stress analysis in the worm and the gear of double enveloping worm gears by finite elements. By using this program stress distributions in the worm thread and the gear tooth are calculated, and the influence of the design parameters and of the load position on deflections and stresses is investigated. On the basis of the obtained results, by using regression analysis and interpolation functions, equations are derived for the calculation of deflections and stresses in the worm thread and in the gear tooth of double enveloping worm gears.
