摘要
应用有限元法考察了齿形误差对齿轮最大接触应力和啮合刚度的影响。基于齿廓方程在ANSYS中精确建立了理想齿廓齿轮有限元模型;基于移动节点的方法,建立了误差齿廓齿轮有限元模型。通过计算啮合周期内多个啮合位置有限元模型,得到了理想齿廓齿轮和误差齿廓齿轮最大接触应力的分布状态,分析了齿形误差对最大接触应力的影响程度;得到了理想齿廓齿轮和误差齿廓齿轮啮合刚度的分布规律,证明了齿形误差降低了齿轮的啮合刚度。
The impact of the tooth profile error on maximum contact stress and meshing stiffness of gear is stud- ied by using method of finite elements. The meshing gear 3 - D finite element model with ideal tooth profile is built by ANSYS based on the tooth profile equations, and the meshing gear 3 - D finite element model with tooth profile error is built by means of moving contact zones nodes. By solving models at different meshing positions in a meshing cycle, the distribution status of maximum contact stress and meshing stiffness of two gears with ideal tooth profile and without tooth profile error are obtained, the extent of the impact of the tooth profile error on maximum contact stress and meshing stiffness is analyzed, and proves that profile error reduces the meshing stiffness.
