4.发动机试验结果上述轴瓦已在各种型式的发动机上运用了相当长的时间。下面的表2～4示出它们与用于3种典型尺寸(中速、大型高速、商用车辆)的发动机的标准双金属轴承和三层金属轴承的对比情况。 5.用油膜峰值压力和最小油膜厚度表示的现代轴承型式的应用线图对于每种规格的发动机,可在许多应用的基础上,根据所要求的使用寿命来确定一种型式轴承的容许范围。下面的图13和图14考虑了各种轴承材料和不同的轴承型式。比较的基础是各种发动
4. Engine Test Results The above bushings have been used for quite a long time on various types of engines. Tables 2-4 below show their comparison with standard bimetallic bearings and three-layer metal bearings for engines of three typical sizes (medium speed, large high speed, commercial vehicles). 5. Application Diagram of Modern Bearing Type with Oil Film Peak Pressure and Minimum Film Thickness For each engine specification, the permissible range for one type of bearing can be determined based on many applications, depending on the required service life. Figures 13 and 14 below consider various bearing materials and different bearing types. The basis of comparison is a variety of launches
