The vibration of the miniature bearing performance factors on bearing performance

The microstructure parameters such as range can keep one. Bearing vibration and noise of the design is different from the fatigue life design. 113 rolling bearing vibration performance influence factors of gray fusion qualitative analysis this section with tapered roller bearing vibration acceleration for the concrete example, based on the grey system theory, put forward the grey qualitative factors affecting performance of the rolling element bearing integration analysis method. There are many influence factors in tapered roller bearing vibration acceleration, the main consideration ring and roller processing quality parameters. Many processing quality parameters, must be targeted to seize one of the main factors, in order to effectively control the bearing vibration acceleration value. In addition, considering the experiment cost, less production field sampling number. How to under the condition of limited number of data, find out the most important factor, has become the key to the problem. According to the principle of rolling bearing lack information experiment analysis and evaluation, more reliable measures is to use a variety of mathematical method of research, many conclusions, because each has its limitations, so deal with the result of ratio analysis and integration, has the commonness of the only conclusion, the conclusion is that affect the tapered roller bearing vibration and speed of the final solution of the most important factor in the problem. 113. 1 bearing performance influence factors analysis of qualitative fusion model set by experience know that there are N independent factors ( Such as the structure parameters and lubrication conditions, etc. ) May affect the performance of the rolling bearing ( Such as vibration) P, there are factors symbol set X of X = ( X1，X2，…，X1，…，Xx) ( 11 - 12) With m kind of mathematical method to deal with the experimental data, get m factors affecting sequence set ( Factors of from big to small order, the greater the impact on the performance factors, and its symbol position to the left) X> P for performance, is what is X1; ＝2，3，…，N ( 11 - 13) So get sort factor matrix symbols: X ( 2) X ( 2) X ( 2) ( 2) X X N2N X =X X N- 1) X ( 2) X ( 2) ( 0) 14) And XCX: k = 1, 2, m; 256 = 1,2,…,N
