Represents the number of times that the friction torque of the set of bearings is greater than that of other bearings. This method can effectively solve the effect of different numerical sequence on the friction torque of rolling bearings. 3.1. The larger the value, the worse the lubrication and operational flexibility of the set of bearings compared with other bearings.
This method synthesizes the overall situation of the two sets of bearing friction torque to judge the timing characteristics of the bearing friction torque, which can avoid the influence of individual larger or smaller data in the data, can reflect the specific comparison of the rolling bearing friction torque, and then characterize the timing characteristics of the rolling bearing friction torque .
Obviously, the two comprehensively reflect the sensitive performance and stability of bearing friction torque, which lays the foundation for the preliminary analysis of bearing friction torque. A small value of s and a larger value indicate The bearing has good sensitivity performance but unstable performance; A.05. Finally, the results of the above three methods are summarized to comprehensively judge the characteristics of the friction torque of rolling bearings, and the bearing with the best performance is selected from a few sets of rolling bearings.
The higher the rank sum R(X) value, the lower the order of the friction torque of the set of bearings, the worse the state characteristics, that is, the poor friction performance of the bearing.01 and 0. C is the standard value under the significance level a in the specific sample space, which represents a benchmark value, and greater than this value indicates that the level of difference has reached a certain degree. 4. Judgment method of the basic characteristics of rolling bearings The basic characteristics of rolling bearings are reflected by the sensitivity coefficient 4 and the stability performance coefficient S.
The smaller the value, the greater the difference in comparison results, and the larger the value, the smaller the difference in comparison results. The smaller the value, the better the sensitivity of the bearing; s, the smaller the value, the better the stability of the bearing: a large value of 4 and a small value of Si indicate poor sensitivity of the bearing but stable performance. Rolling bearing state feature evaluation method The rolling bearing state feature evaluation method adopts the rank sum evaluation method.
Generally, the significance level a takes the values 0. Evaluation method of rolling bearing timing characteristics Clutch Release Bearing In the evaluation of rolling bearing timing characteristics, the significance level a is a state parameter that measures the level of friction torque of rolling bearings. 2. For general equipment, the confidence level of friction torque is 95%; for important equipment, the confidence level of friction torque is 99%~100%.. and s, both large values indicate that the bearing has poor sensitivity performance and unstable performance
