| Abstract: | Based on 2 D finite element analysis method,considering some factors of modification on addendum and tool round angle, a parametric general 2 D finite element analysis model and its pre processing and post processing program are put forward in this paper. The tooth root stress of cylindrical gear has been calculated and analyzed in detail, and compared with the result obtained by the load bearing capacity computing method of cylindrical gear (GB3480 83).The influences on tooth root stress caused by variations of load point and tool round angle are also analyzed. |
