The Bearing Characteristics of Hydrostatic Gas Bearings with Hybrid Restrictor. Experimental Study.

Numerical Study on the Static Characteristics of Novel Aerostatic Thrust Bearings Possessing Elastomer Capillary Restrictor and Bearing Surface

In this paper a novel design of aerostatic thrust bearing is proposed and is analyzed numerically. The capillary restrictor and bearing disk are made of elastomer like silicone and PU. The viscoelasticity of elastomer helps the capillary expand for more air flux and at the same time, allows conicity of the bearing surface to form when the air pressure is enhanced. Therefore the bearing has the ...

Experimental Modeling of a Long Orifice-type Restrictor of High Speed Turbine Hybrid Bearing

To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...

The Critical Speeds of a Machine Tool Spindle- Bearing System with the High Stiffness Hydrostatic Journal Bearings

INTRODUCTION The ordinary hydrodynamic bearings have been replaced by the hydrostatic bearings in the application of machine tools in recent years. For the hydrodynamic bearings, the journal and the bearing surface are separated by the sliding action with a wedge pressure-generating mechanism to develop a pressure within the bearing. It has advantages of simple structure and cheap cost. However...
