Application of Fuzzy Statistics Evaluation Theory for Analyzing the Performance of Rolling Bearings

Xintao Xia, Liang Ye, Zhen Chang

This paper discusses the basic process of fuzzy statistics evaluation, which is based on fuzzy system theory. A type of deep groove ball bearing (type 6203) and two types of tapered roller bearings (type 32210 and 30204 ) are used as examples in this work; the statistical analysis results are derived using classical methods and compared with the results from fuzzy statistics. The method is proven to be scientific and reasonable based on the results of the experimental investigation. The evaluation method reduces the influence of subjective factors, improves the accuracy of the economic conclusions and provides a method for determining the performance of rolling bearings and other products.
