Posouzeni napjatosti pruzneho kola harmonickeho ozubeneho prevodu komparacni metodou

Abstract

This study deals with a state of stress of a flexspline of harmonic drive. The principle, function and utilization of the harmonic drive are briefly described in Chapter 2. Examples of construction of those with segmental wave generators are presented. Discussion of the state of stress of a shell of flexspline based on linear elasticity is presented in Chapter 3. The study is focused on evaluation of it in the harmonic drive based on a comparative method. Possibilities of it for optimalization of a design of highly stressed parts are described in Chapter 4 devoted to method oy. This chapter precedes both experimental and calculation both the study. In the former part finding out of a stress in a given point of the shell of flexspline by a tenzometrical measuring is given. In the latter one a model constructed by a finite elements method is described. It is evaluation with regard to global quantities is described in comparison with the results of the experiment. Results of computation of the shell of flexspline based on the finite elements method are presented. There are also a discussion and comparison of results obrained both in computation and experiment presented in the frame of the comparative methodAvailable from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
