摘　　要：游隙是影响滚动轴承性能的一个重要参数。研究了游隙对单排四点接触球转盘轴承载荷分布的影响规律。首先,建立轴承的静力模型并得到一组平衡方程;然后,以两套具有不同几何参数及外部载荷的轴承为例,利用静力模型计算了轴承的载荷分布。结果表明:随着游隙的增大,承担载荷的滚动体数目逐渐减少,受载最大的滚动体载荷也逐渐增大。当游隙往小处取值时,有利于提高轴承的承载能力。Clearance is an important parameter influencing on the performance of the rolling bearings. The influence law of clearance on load distribution of single row four-point contact ball slewing bearings is researched. Firstly, the statics model of the bearing is established and a set of equilibrium equations are obtained. Then, two bearings having different geometrical parameters and external loads are used as cases, the loads distributions are computed by using the statics model. Results show that with the increase of the clearance, the number of milers undertaking the loads begins to decrease and the load of the miler undertaking the maximum load begins to increase gradually. If a smaller value is selected for the clearance, it is propitious to improve the carrying capacity of the bearing.
