Radially mobile bearing for a shaft pertaining to a steering system
A radially movable bearing for a shaft of a gear in a steering system includes a bush or outer ring that is supported in a receiving element of a mount or housing for the gear. In order to create a radially flexible bearing for the shaft of the gear, which movable bearing enables quiet operation for the entire service life of the gear, the outer ring or the bush is held by at least one support element that is inserted in a gap between the receiving element and the outer ring, and that is made of a material with elastomer behavior.
1. A radially movable bearing for a shaft of a gear in a steering system, comprising:
an outer ring which is retainable in a receiving element of a mount or housing for said gear with a gap being defined between said outer ring and said receiving element;
a support element that is inserted in the gap between said receiving element and said outer ring, said support element being made of a material with elastomeric characteristics, said outer ring being held by said support element, said support element being embodied as a pivot bearing having a pivot axis that runs approximately parallel to a longitudinal axis of said shaft;
a pivot bush including an inner ring and a support ring, said inner ring and/or said support ring including a passage in a radial direction of said radially movable bearing; and
a pressing device for said shaft, said passage receiving said pressing device therethrough.
2. A radially movable bearing for a shaft of a gear in a steering system, comprising:
an outer ring which is retainable in a receiving element of a mount or housing for said gear with a gap being defined between said outer ring and said receiving element;
a support element that is inserted in the gap between said receiving element and said outer ring, said support element being made of a material with elastomeric characteristics, said outer ring being held by said support element, said support element being embodied as a pivot bearing having a pivot axis that runs approximately parallel to a longitudinal axis of said shaft;
an inner ring being fixed on said outer ring, said inner ring being comprised of a material with elastomeric characteristics; and
a support ring which is comprised of the material with elastomeric characteristics, said support ring being fixed in said receiving element of said mount or said housing for said gear;
said inner ring, said support element, and said support ring are formed in a single piece from the material with elastomer behavior and comprise a single-piece pivot bush for said radially movable bearing, said support element extends approximately across an entire axial length of said pivot bush.
3. A radially movable bearing for a shaft of a gear in a steering system, comprising:
an outer ring which is retainable in a receiving element of a mount or housing for said gear with a gap being defined between said outer ring and said receiving element;
a support element that is inserted in the gap between said receiving element and said outer ring, said support element being made of a material with elastomeric characteristics, said outer ring being held by said support element, said support element being embodied as a pivot bearing having a pivot axis that runs approximately parallel to a longitudinal axis of said shaft;
a support ring which is comprised of a material with elastomeric characteristics, said support ring being fixed in said receiving element of said mount or said housing for said gear, said support element being supported on said support ring, at least one of said support ring or said inner ring of said pivot bush has varying wall thicknesses.
4. A radially movable bearing according to claim 3 , wherein at least one of said support ring or said inner ring of said pivot bush includes at least one area having greater wall thickness which acts as a stop for said inner ring.
