摘要
对８个具有不同腹板布置的薄轮缘圆柱斜齿轮结构进行了模态实验研究。齿轮腹板布置采用航空齿轮传动中常用的三种形式：立腹板、斜腹板和一端腹板。实验结果表明，腹板厚度的改变较轮缘厚度的改变对齿轮结构固有频率的影响更大，腹板布置形式对齿轮结构各阶固有频率的影响不完全相同。文中将实验结果与三维有限元计算结果进行了比较。
Modal experiments of eight thin-rimmed helical gear structures with different web arrange-ments are carried out in this paper. Three adopted tpe of web arrangements are plain, inclined andone-side web respectively. Test results show that the influence of web size variation on natural fre-quencies of thin-rimmed gear structure is larger than the influence of rim size variation. The typesof web arrangements have different influenas on natural frequencies of gear structures. The test re-sults are compared with those obtained by 3-D FEM.
