利用MATLAB软件算出正交面齿轮的理论齿面数据点,然后通过Pro/E三维造型软件把面齿轮的几何模型绘出及装配出整个面齿轮副,求出了面齿轮理论接触点坐标,实现了面齿轮接触轨迹的可视化,同时,以赫兹理论为基础,首先通过单对齿的接触分析确定了有限元求解收敛情况下的网格密度,然后研究了多对齿接触情况下的接触斑点;并且通过仿真分析研究了面齿轮在不同工况下的传动误差,得出结论,在设定的三种不同工况载荷下,面齿轮承受转矩载荷越大,传动误差越大,转速对面齿轮传动误差几乎没有影响,当面齿轮有0.02°轴交角安装误差的情况下,面齿轮的传动误差幅值是没有安装误差情况下幅值大小的2.0~2.3倍。
Using MATLAB software to calculate the theoretical tooth surface data points of the orthogonal gear, and then through the Pro / E three-dimensional modeling software to draw and assemble the surface gear geometry model of the entire surface gear, obtained the surface gear theoretical contact point coordinates, to achieve At the same time, based on the Hertz theory, the mesh density under the condition of convergence of the finite element solution was determined by the contact analysis of a single pair of teeth. Then, the contact spots under the condition of multiple pairs of teeth were studied. And through the simulation analysis of the surface gear transmission error in different conditions, concluded that the set of three different conditions under load, the greater the surface gear torque load, the greater the transmission error, the speed of the gear opposite Transmission error has almost no effect, face gear with 0.02 ° axis angle installation error case, the face gear transmission error amplitude is not installed error amplitude size of 2.0 to 2.3 times.
