Hydrostatically gas lubricated slide bearing

摘要

A hydrostatically gas-lubricated plain bearing arrangement has as bearing elements, which accommodate a wheel body in a rotatable manner, two bearing cones (2) which are rigidly fixed on a fixed axle (1) made up of two halves (1a, 1b). Lubricating-air pockets (7) with counterbores (9) and air-supply bores (8) are provided on the external conical surfaces of the bearing cones. The lubricating air is supplied into the air-supply bores (8) through the hollow axle (1) via air-distribution channels (28). For setting the bearing gaps, the mutual distance of the two bearing cones (2) can be changed by a threaded sleeve (18) inside one axle half (1b) in interaction with a threaded spigot (17) of the other axle half (1a).
