Dynamic Quality of an Aerostatic Thrust Bearing with a Microgroove and Support Center on Elastic Suspension

The disadvantage of aerostatic bearings is their low dynamic quality. negative impact on the characteristics bearing exerted by volume air contained in gap, pockets, and microgrooves located at outlet feeding diaphragms. Reducing flow path a resource for increasing quality bearing. This article presents an improved design axial with simple diaphragms, annular microgroove, elastic suspension movable center supporting disk. A mathematical model presented methodology calculating static indicators described. calculations were carried out using dimensionless quantities, which made it possible to reduce number variable parameters. new method solving linearized Laplace-transformed boundary value problems transformants pressure functions layer was applied, obtain numerical solution sufficient practice accuracy. optimization criteria out. It shown that use support improves its reducing compressed choosing optimal microgroove.
