Cyclic symmetric analysis of fabricated gear wheels

A computer aided method of analysis of the web portion of a spur gear is presented The cyclic symmetric concept is used for solving the problem of the steady state stress analysis (asynmetric loading) when the gear is subjected to a concentratd edge load due to the mating tooth The effect of cut-outs in the web is studied The response of the web to a moving load is investigated• The ratio of the forcing frequency to the fundamental frequency of the gear wheel being small, the moving load is approximated as a static load acting at different points. The influence of radial ribs on the behaviour of the gear is also studied.
