一般都认为润滑油的清洁度对轴承寿命有直接影响。过去,对润滑油中的微小异物会引起轴承损伤,或者影响轴承寿命的问题虽然也有所了解,但实际上在设计轴承时或在使用轴承过程中做寿命计算时就很少定量地考虑这个问题了。 近年来,在轴承的修正寿命计算公式中,制造厂家多以系数的形式来考虑轴承滚动体与内外圈滚道接触面的润滑油粘度和清洁度的影响。润滑油的清洁度只 Generally agreed that the cleanliness of lubricants on the bearing life has a direct impact. In the past, tiny foreign particles in the lubricant can cause bearing damage, or affect the bearing life Although the understanding of the problem, but in fact the design of bearings or bearing life calculation in the use of very few quantitative consideration of this issue It’s In recent years, in the revised bearing life calculation formula, the manufacturer mostly in the form of coefficients to consider the bearing rolling elements and inner and outer raceway contact surface of the lubricant viscosity and cleanliness. Cleanliness of lubricants only
