以30204型圆锥滚子轴承试验数据为基础，利用灰色模糊聚类分析方法对影响圆锥滚子轴承振动的 因素进行了综合分析，将圆锥滚子轴承各项参数按其对振动的影响分为三类：第一类对振动的影响最大，其 中包括滚子凸度、滚子直径偏差D_w 等参数；第二类对振动的影响较大，其中包括内滚道圆度，内滚道直线性 L_i 等参数；第三类对振动的影响最小，其中包括内滚道波纹度，内滚道的角度偏差Δ２β 等参数。根据分类可 知，试验中圆锥滚子轴承的大部分参数都会对振动产生较大的影响。

By using the fuzzy cluster analysis of grey system theory to analysis the test data of type-30204 tapered roller bearing, the parameters can be classed into three groups by their effects on the vibration. The parameters in the first group have big effect on the vibration ; this group is composed of the convexity of the roller, deviation of the roller diameter, etc. The parameters in the second group have less effect on the vibration,include:the roundness of the inner race, the linearity of the inner ring, etc. The parameters in the last group have the least effect on the vibration of the tapered roller bearing, including the waviness of the inner race, the angle deviation of the inner ring. It can be concluded in this paper that, most parameters of tapered roller bearing have big effect on the vibration.
