摘要
对气流纺高速纺杯球轴承系统的力学问题提出了一种数值方法,并且描述了相应的求解过程。该方法以拟静力学分析方法为基础,依据一般动力学方程,分析了轴承内部的几何关系、钢球运转速度和接触变形的相互影响,并建立起一组相应的非线性方程组。通过采用离散型牛顿叠代法求解,导出了该纺杯球轴承的接触应力、钢球与内外沟道的接触变形量、动态接触角等方面的参数。此外,对最佳静态接触角的计算也进行了公式推导与估值。
This paper provides a numerical method to solve the mechanical problems in high speed ball bearing system of open-end spinning, and describes the whole related process of such a method.
On the basis of quasi-static analytic method and the general dynamical equations, this paper attempts to analyse the interaction between the internal geometrical relation of the bearing, the ball revolving speed and the contact deformation,and a set of relevant non-linear equations are established. Then, by using discrete Newton iterative method, some parameters e.g. the contact stress of the ball bearing, the degree of contact deformation between ball and inner or outer race,and the dynamic contact angle are derived. Besides, this paper has also derived some formula and made some estimates for calculation of the best static contact angle.
