摘要

为了研究齿廓误差对斜齿轮接触特性的影响,推导出含齿廓形状误差和齿廓倾斜误差的渐开线方程,并在ANSYS中建立了含齿廓误差的有限元模型,基于该模型获得了齿廓误差对最大接触应力、弯曲应力、载荷分布的影响规律。结果表明,齿廓形状误差和齿廓倾斜误差降低了齿轮的接触强度和弯曲强度,改变了齿轮的载荷分配状况,当齿廓形状误差大于5μm或齿廓倾斜误差等于0.5°时,齿轮由三齿啮合逐渐变为双齿啮合,双齿啮合逐渐变为单齿啮合,影响了齿轮的承载能力。

Abstract

In order to study the influence of profile deviations on the contact characteristic of the helical gear,the involutes equation containing the profile form deviation and profile slope deviation is deduced.On the meanwhile,a finite element model containing tooth profile deviations is established.Based on this finite element model,the effect law of the profile form deviation and profile slope deviation on the maximum contact stress,bending stress and load distribution is obtained.The result suggests that the contact strength and bending strength of gears is reduced by the profile form deviation and profile slope deviation and the load distribution status is changed.When the profile form deviation is larger than 5μm or the profile slope deviation equals to ±0.5°,the gearwill gradually change tooth meshing number from three to two,then two to one,which brings certain impact on the carrying capacity of gear.
