Abstract: A rotating shaft of a rotating machine is supported at its both ends by bearing bushes which are held in a frame of the rotating machine. The outer periphery of the bearing bush is rounded and held with a rounded surface formed on the frame, so that the rotational axis of the shaft and the bearing are self-aligned by rotation of the bearing bush. The inner bore of the bearing bush rotatably supporting the shaft therein is shortened by forming a relief bore, the diameter of which is larger than that of the inner bore. Because of this bearing structure, a natural vibration frequency of the shaft varies less, and, therefore, the rotating machine can be easily designed so that harmful noises due to the natural vibration are sufficiently suppressed.

The bearing includes a base element and a cap element matable about the shaft to produce the bearing housing. The bearing housing when assembled includes a shaft receiving portion through which the shaft extends and a sump portion for containing a lubricant fluid.

Abstract: A process for manufacturing ball joints or other self-lubricated joints, comprising placing the inner ring of the ball joint in a heat-retractable sheath of determined thickness and shrinking the sheath on this inner ring. The inner ring is then disposed in an outer ring blank which is then deformed so that the sheath is clamped between the outer and the inner ring. After machining of the blank, the assembly is treated so as to eliminate the heat-retractable sheath and thus form between the two rings a free space whose thickness corresponds to that of the sheath. A self-lubricating resin is then injected in this space.
