| 摘 要： | 齿间载荷分布系数的确定一直是齿轮强度计算中一个复杂的问题,实际工程计算采用经验数据常常不尽人意,本文在利用接触强度有限元的基础上,采用双齿模型,主动轮绕其轴心转动,固定被动齿轮,将主动轴上的扭矩处理成圆弧边界上的分布载荷,将制造安装误差考虑成初始间隙而得到符合轮齿啮合齿间载荷分布的有限元模型,通过计算并与传统公式比较得到符合实际的齿间载荷分配系数,从而解决了设计中的实际问题,为齿间载荷分配系数的确定开拓了新的思路。

| Abstract: | The determination of load share between teeth is a complex problem in gear strength calculation.On the basis of contact finite element method this paper considers the production-assembly error as initial gap to get the finite element model which meets load share between teeth in gear meshing.Through calculating and comparing the result with that from ISO formula to get the load share between teeth which meets the requirements in actual usage. |
