摘要
滚动轴承在运转过程中,其振动特性会受到各零件表面波纹度的影响。以滚动轴承为研究对象,建立内圈、外圈和球的表面波纹度模型,并将模型计算结果与试验结果进行对比以验证模型的正确性。基于表面波纹度模型分析了深沟球轴承内圈、外圈和球表面波纹度对轴承振动特性的影响,结果表明:在低频段,内圈表面波纹度对轴承振动特性的影响最大;中、高频段,球表面波纹度对轴承振动特性的影响最大;在低、中、高频段,轴承振动速度有效值均随着内、外圈表面波纹度的增大而增大。
During operation of rolling bearings,their vibration characteristics are affected by surface waviness of each part.Taking rolling bearings as research object,the surface waviness models of inner ring,outer ring and balls are established,and the calculation results of these models are compared with test results to validate their accuracy.Based on surface waviness models,the effects of surface waviness of inner ring,outer ring and balls on vibration characteristics of deep groove ball bearings is analyzed.The results show that in low frequency band,the surface waviness of inner ring has the most significant impact on vibration characteristics of the bearings;in medium and high frequency bands,the surface waviness of balls exerts the greatest influence;in low,medium and high frequency bands,the RMS vibration velocity of the bearings increase with the increase of surface waviness of inner and outer rings.
