将一透平机械中的中型推力轴承通过相似模型化得到模型试验小型轴承，对其承载能力进行了实验，得到了轴瓦的进、出油温度和支点处的油膜厚度。实验表明，可用支点处的油膜厚度来代替最小油膜厚度的测量，为工程实际提供了一种新的测量思路 A medium-sized thrust bearing in a turbine is simulated by a similar model to obtain a miniature bearing. The bearing capacity of the bearing is tested, and the temperature of the oil in and out of the bearing and the thickness of the oil film at the fulcrum are obtained. Experiments show that the thickness of the oil film at the fulcrum can be used to replace the measurement of the minimum oil film thickness, which provides a new measuring idea for engineering practice
