Abstract
A Cardan shaft bearing is disclosed in which the outer ring of an antifriction bearing and a retainer ring are connected together by a rubber ring which is vulcanized in place. The outer ring and the retainer ring rest with radial elasticity against each other. The rubber ring has a U-shaped profile which is open parallel to the axis of the Cardan shaft bearing. The rubber ring is fixed on the outer ring and on the retainer ring at least in part on the axial ends of these rings. The inner ring of the antifriction bearing is provided with rubberizing on the side facing the shaft.
Claims24
A shaft bearing for a rotating shaft comprising:
- an antifriction bearing comprising an inner and an outer ring, said inner ring comprising rubberizing on a radial surface faring said shaft;
- a retainer ring;
- a rubber ring connecting said outer ring and said retainer ring, said rubber ring comprising a U-shaped profile which is open in a direction parallel to an axis of said shaft bearing, said rubber ring being fixed at least partially on axial ends of said outer ring and said retainer ring.
A shaft bearing for a rotating shaft comprising:
- an antifriction bearing comprising an inner and an outer ring, said inner ring comprising rubberizing on a radial surface facing said shaft;
- a retainer ring;
- a rubber ring connecting said outer ring and said retainer ring, said rubber ring comprising a U-shaped profile which is open in a direction parallel to an axis of said shaft bearing, said rubber ring being fixed at least partially on axial ends of said outer ring and said retainer ring,
- wherein said retainer ring rests on an elastic spring ring.
A shaft bearing for a rotating shaft comprising:
- an antifriction bearing comprising an inner and an outer ring, said inner ring comprising rubberizing on a radial surface facing said shaft;
- a retainer ring;
- an elastic spring ring connected to said retainer ring, said spring ring comprising liquid-filled cavities distributed circumferentially, said liquid-filled cavities being in communication with each other via openings;
- and
- a rubber ring connecting said outer ring and said spring ring, said rubber ring comprising a U-shaped profile which is open in a direction parallel to an axis of said shaft bearing.
