The testing system comprises a testing table, a cooling system, a lubricating system, and an electric control system, wherein the testing table comprises a motor, a dynamic pressure bearing, a flywheel, a shaft coupler and a testing base; the cooling system and the lubricating system are connected through a pipeline testing table and are used for respectively providing the cooling function and the lubricating function for the testing system; the electric control system is connected with the testing table through a cable; the remote control can be realized through a programmable controller and a frequency converter, the starting speed, the stopping speed and the rotating speed of the motor can be changed; various possible working conditions in actual use are systematically simulated and analyzed, and the system can be monitored in real time through a temperature sensor and a vibration sensor; and therefore, the reliability of product research and development is guaranteed, the research and development time is shortened, and the research and development progress is accelerated.

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 a mechanical system, a motor drive system, a dynamic pressure l...
