以摩擦功为准则,计算齿面上各处跑合量,与由啮合原理计算齿面上各处间隙量相结合,计算出跑合过程中齿面瞬时接触迹上的压力分布。计算结果纠正了认为跑合后压力沿齿高均匀分布的结论,为圆弧齿轮接触应力的精确计算提供了依据。还提出用涂色液灌注的方法,实测了加载啮合的静态接触迹的形状和大小,验证了本文提出的跑合计算结果。 Based on the friction work principle, the amount of running on the tooth surface was calculated and the amount of clearance on the tooth surface was calculated by the meshing principle. The pressure distribution on the instantaneous contact surface of the tooth surface during running-in was calculated. The calculation results correct the conclusion that the pressure distribution is uniform along the tooth height after running-in, which provides a basis for accurate calculation of contact stress of circular arc gear. It is also proposed to use the method of perfusion of coating liquid to measure the shape and size of the static contact track of loading engagement, which verifies the running calculation result proposed in this paper.
