由于结构紧凑,加工方便,配合精度高,密封性较好,压力高,易于实现变流量等许多优点,而广泛应用的轴向柱塞泵,在转子和配油盘之间、滑覆与斜盘之间存在着大压强的端面滑动摩擦。测量运转状态下的油膜厚度,对研究其润滑状态,设计、维修轴向柱塞泵有很大的意义。由于受工作状态的限制,油膜厚度的测量必须采用非接触式测量,但又不能用光学测量仪器。我们应用
Due to its compact structure, easy processing, high precision, good sealing, high pressure, easy to achieve variable flow and many other advantages, and widely used axial piston pump, between the rotor and the oil pan, sliding and oblique There is a big pressure between the disk sliding friction. Measuring the operating condition of the film thickness, the study of its lubrication, design, maintenance of axial piston pump has great significance. Due to the working conditions of the restrictions, the film thickness measurement must be non-contact measurement, but can not use optical measuring instruments. We apply
