一般文献中所称的滾动軸承寿命,通常即为軸承的計算寿命、基准寿命或保証寿命的同义略語,它是指受試驗的一批軸承在相同条件下运轉时,有90%以上軸承的工作表面不出現金属疲劳現象而达到的工作小时数。疲劳現象的特征,是在軸承零件的工作表面上出現了点状的或局部的金属剝落痕迹。国內外的試驗都表明,同一型号的一批軸承,即使在严格保持一致的条件下进行試驗,其結果往往也会
Rolling bearing life in the literature generally referred to as the calculation of bearing life, reference life or synonymous with guaranteed life, it refers to a group of tested under the same conditions when the operation of the bearings, more than 90% Working surface of the bearing metal fatigue does not appear to reach the number of working hours. Fatigue is characterized by the appearance of punctate or localized metal flaking marks on the working surfaces of bearing components. Domestic and foreign tests have shown that the same type of a number of bearings, even if strictly consistent test conditions, the results will often
