| Summary: | 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 rollers undertaking the loads begins to decrease and the load of the roller 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. |
