摘要

针对ANSYS中建立斜齿轮啮合实体模型困难的问题,提出了一种基于APDL参数化建立斜齿轮啮合实体模型的方法。基于齿廓曲线方程,建立位于基准位置的主、从动轮实体模型;以接触线总长最小时的啮合位置为初始啮合位置,确定主、从动轮由基准位置到初始啮合位置的转动相位,将主、从动轮旋转至初始啮合位置,建立斜齿轮初始啮合实体模型;建立一个接触线分布变化周期内斜齿轮副的啮合相位变化方程,通过对方程中啮合相位系数的控制,实现对接触线分布变化周期内斜齿轮副任意啮合位置的捕捉。数值实验的结果表明,基于该建模方法生成的斜齿轮啮合实体模型具有良好的几何精度,能够保证斜齿轮啮合仿真结果真实可信。

Abstract

To solving the problem that it is difficult to build an accurate solid model of meshing helical gears in ANSYS,a new parameterized approach to building an accurate solid model of meshing helical gear based on APDL is presented. The solid model of helical gear pair is built at the reference position based on the equations of the tooth profile curve equation. Taking the meshing position that helical gear pair has the minimum total length of contact lines as the initial meshing position,the rotational phase from the reference position to the initial meshing position of helical gear pair is determined,the initial solid model of meshing helical gears is built by rotating the helical gear pair based on the rotational phase. The equation of phase change in one contact lines distribution change cycle of meshing helical gears is established,then,the every meshing position of meshing helical gears in one contact lines distribution change cycle can be caught by the control of the meshing phase factor in the equation. The results of numerical experiment show that the meshing solid model of helical gear generated by the presented method has a good geometric precision,which can guarantee that the simulation results is credible.
