在力的平衡和断面法原理的基础上,本文提出了用一种新的方法——锥面法来分析确定向心推力滚动轴承所受的轴向载荷,并将此法归纳为三个计算步骤,简称为三步法。锥面法不仅扩大了平面断面法原理的应用范围,尤其是当向心推力滚动轴承组合不同,以及轴上作用的径向力和轴向力的大小、方向、作用位置出现不同情况时,用锥面法来确定轴承所受的轴向载荷,既简单叉准确。 Based on the balance of force and the principle of cross-section method, this paper presents a new method - the cone method to analyze and determine the axial load on the thrust ball bearings, and this method is summarized into three calculation steps , Referred to as three-step method. Conical surface method not only expands the scope of the application of the principle of plane section method, especially when the combination of radial thrust roller bearing is different, as well as the shaft radial force and axial force size, direction, the role of the position of different situations, the cone Surface method to determine the bearing axial load, both simple and accurate fork.
