一、引言人们计算油膜厚度的能力已表明预测动载荷下轴瓦承载能力的技术有所提高。即使计算中对轴与轴瓦座的变形、滑油粘度随压力的变化以及倒角范围内油膜不充分等因素在计算过程中忽略不计,油膜厚度计算值与实测值之间也有较好的一致性。各种负荷及转速工况下的油膜厚度的计算值进行比较后,设计人员就能通过预测油膜厚度的最小值来判断这些工况相对苛刻性。然而,最小油膜厚度这一个标准并不十分重要。事实上,有些最小油膜厚度更薄 I. INTRODUCTION The ability of people to calculate oil film thickness has shown that the technology for predicting the bearing capacity of bearing pads under dynamic load has increased. Even in the calculation of the shaft and bearing seat deformation, the viscosity of the oil with pressure changes and chamfering within the oil film is not sufficient and other factors in the calculation process is negligible, the calculated thickness of the oil film and the measured value is also in good agreement . By comparing calculated values ​​of oil film thickness for various loads and speeds, designers can determine the relative harshness of these conditions by predicting the minimum film thickness. However, the minimum film thickness of this standard is not very important. In fact, some of the smallest film thickness thinner
