Abstract

The invention relates to the technical field of foil gas bearing load loading experiment devices, and specifically relates to a foil gas bearing comprehensive experiment table device that comprises anaxial load loading unit, a radial load loading unit, a rotor system experiment table main body unit, a sensor unit and a base; the axial load loading unit, the radial load loading unit, the rotor system experiment table main body unit and the sensor unit are fixedly connected with the base; a rotating shaft penetrates through the rotor system experiment table main body unit, the rotating shaft isrotatably connected with the rotor system experiment table main body unit, and the axial load loading unit and the radial load loading unit respectively apply axial and radial loads to the rotating shaft. The invention also provides a fail gas bearing comprehensive experiment method. The characteristics of the foil gas bearing under different loads and different medium environments are researchedby changing the loads and the gas medium. The loading process is free of friction, small in vibration, stable and reliable in static load and controllable in dynamic load size and frequency.

Description

technical field [0001] The invention belongs to the technical field of a foil gas bearing load loading experiment device, and in particular relates to a foil gas bearing comprehensive test bench device and an experimental method. Background technique [0002] Rotating machinery has important applications in various fields. With the continuous growth of China's economy, the development of rotating machinery equipment is paying more and more attention to environmental impact and energy efficiency. As a key component in rotating machinery equipment, bearings play a vital role in the development trend of energy equipment. Currently commonly used bearing types are oil-lubricated sliding bearings, rolling bearings, ceramic bearings, electromagnetic bearings, gas bearings, etc. As a high-tech product rapidly developed in the bearing industry, foil gas bearings have many advantages compared with traditional rolling bearings or oily sliding bearings, such as non-contact support duri...
