摘要:研究圆锥滚子轴承在预紧状态下轴向载荷与预紧力矩及最小预紧力的关系。首先,对受载的圆锥滚子轴承的滚子进行受力分析,推导轴向载荷和滚子的内、外滚道,内圈挡边法向接触载荷的关系;其次,通过对滚动体的内、外滚道,内圈挡边的法向接触载荷与预紧力矩的分析,推导轴向载荷与预紧力矩的关系;并且,针对一对圆锥滚子轴承,讨论其轴向载荷与最小预紧力的关系。通过以上分析,最后得出圆锥滚子轴承在预紧状态下轴向载荷与预紧力矩的线性关系和最小预紧力的表达式。

Abstract:The purpose of this paper is to research the relationship between axial loading and tightening torque and the minimum preload of the tapered roller bearings under the preload condition .Fristly,through analysing the roller's stress state of the loaded tapered roller bearings,I would derive the relationship between axial loading and the normal contact force which exist in the roller's inner raceway,outer raceway and the inner wall.Secondly,I would investigating the relationship between the inner raceway and outer raceway and the inner wall and tightening torque of the rolling elements in order to get the relationship of axial loading and tightening torque.In addttion,for a pair of tapered roller bearings,the relationship between axial loading and minimumpreload would be discussed.Finally,given the above analysis,it would to come to the conclusion that there is a linear relationship between axial loading and tightening torque of tapered roller bearing.The expression of the minimumpreload will also be obtained.
Key wordstapered roller bearings;axial loading;tightening torque;minimum preload
