本文从弹流角度分析了修形前后线载荷分布及最大压力沿接触线的变化规律。本文应用Ｎｅｗｔｏｎ—Ｒａｐｈｓｏｎ方法与Ｎｅｗｔｏｎ下山法相结合的办法，在假定刚体中心膜厚相等的前提下，首先求出了修形前斜齿轮某一时刻全接触线上的弹流润滑解。进而求解出修形后斜齿轮某时刻全部接触线各点的载荷分配、压力分布和油膜形状。在文献［４］的基础上，研制了一套微机数据采集和处理系统，测量了斜齿轮的中心油膜厚度，测量结果与计算结果基本一致。
This paper analyzes the variation of the line load distribution and the maximum pressure along the line of contact before and after the modification from the spring-flow angle. In this paper, the combination of Newton-Raphson method and Newton’s downhill method is used to calculate the EHLs on the full contact line of the bevel gear at a certain moment before assuming the equal film thickness at the center of the rigid body. Then the load distribution, pressure distribution and oil film shape at all points of contact line at a certain moment of helical gear modification are solved. Based on the literature [4], a set of microcomputer data acquisition and processing system was developed to measure the central oil film thickness of the helical gear. The measured results are in good agreement with the calculated ones.
