Body hydrodynamic bearing.Since frictional resistance is small, bearing capacity is strong and structure is simple, hydrodynamic bearing has in the industry is widely answered
With.
For hydrodynamic bearing using liquid (such as lubricating oil) as lubricant, bearing capacity is stronger.However work as axle journal linear speed
When degree increases, the friction loss of bearing is incrementally increased, and makes the heat dissipation problem of lubricant very prominent while increasing power consumption.It is existing
Axle journal linear velocity when stage typical hydrodynamic bearing is run is typically not greater than 60m/s, restricts hydrodynamic bearing and exists
The application of high engine speed range.
Aero dynamic bearing using surrounding air as lubricant, due to gas viscosity be about liquid viscosity thousand/
One, therefore bearing friction loss is minimum.Aero dynamic bearing is in the aircraft air circulatory system, accessory power system and turbine
It is applied in the high-speed rotating machines such as expanding machine, axle journal maximum linear velocity is up to 240m/s or more when operation.However gas
Hydrodynamic bearing, which needs rotor (that is, shaft) revolving speed to reach certain limit value, could generate dynamic pressure air film, and usual rotor takes off linear velocity
Greater than 20m/s, in the rotor start-stop stage, axle journal directly contacts to bring abrasion with bearing；In addition, steady in bearing operational process
It is qualitative relatively poor, the unstable phenomenons such as whirling motion and dry friction are easy to appear, it is even urgent to have to reduce speed for equipment after unstability
It shuts down, the severe jamming steady operation of system.
For improve aero dynamic bearing stability and reliability, there has been proposed paillon, compressed spring, wire mesh,
The support constructions forms such as bulge, the mixing of paillon-wire mesh, improve the performance of bearing to a certain extent, however above structure
The shortcomings that not overcoming gas lubrication inherently, effect is limited.
