A New Type of Air Bearing for Air-Driven High Speed Centrifuges

Abstract

Described in this article are the two latest types of drive mechanisms for the well-known air-driven centrifuges. The advantages claimed are greatly improved damping of vibration, and the elimination of troubles due to variations in the air supply pressure. The drawings and description are sufficiently detailed to permit construction without further information, although they are notably difficult to follow in detail. The essential novelties in these new designs are a new type of air support bearing which is not critical of the air supply pressure, and a very ingenious system by which the lubricating oil acta to damp out vibration without interfering with the sealing and lubricating functions.
