Description

technical field [0001] The invention relates to the technical field of overall performance measurement of dynamic pressure sliding bearings, in particular to a double-span dynamic pressure sliding bearing test bench capable of applying dynamic loads. Background technique [0002] Fluid lubricated sliding bearings are divided into dynamic pressure sliding bearings, static pressure sliding bearings and dynamic and static pressure sliding bearings according to the lubrication mechanism. The advantages of dynamic pressure sliding bearings are low cost, long life, simple lubrication, high radial positioning accuracy, good running stability, low noise, good absorption of external vibration and low power consumption, and are mostly used in high-speed and high-precision machinery among the equipment. [0003] Research on sliding bearings has always been valued by people. At present, most of the test benches for dynamic pressure sliding bearing research are aimed at the research of...
