Description

technical field [0001] The invention relates to a test system, in particular to a high-speed load dynamic pressure bearing test system. Background technique [0002] For the slewing bearings of high-speed and heavy-duty rotating shafts in industrial equipment, hydrodynamic bearings are used in many cases. Hydrodynamic bearings are sliding surfaces that are separated by a liquid film that is automatically formed by the dynamic pressure of liquid lubricants and bears loads. Bearings, however, have relatively high requirements in terms of design, materials and manufacturing processes. Therefore, in the process of product development, performance tests that simulate actual working conditions must be carried out to ensure that various technical indicators of the product meet the design requirements. [0003] Patent CN 102279105 A discloses a rolling mill oil film bearing comprehensive test bench, which is composed of mechanical system, motor drive system, hydraulic loading system...
