Abstract
An antifriction bearing with an outer ring having a main groove in its periphery. The groove has sharp edges which engage the interior of a housing surrounding the outer ring. Alternately, a secondary groove may adjoin an axial side or both axial sides of the main groove. A deformable material ring having its own radially outwardly facing deformation remitting groove may be disposed in the main groove in the outer ring. The deformable ring protrudes radially out of the main groove to be deformed by the internal wall of the housing around the bearing.
Claims19
An antifriction bearing having an outer ring, an inner ring inside the outer ring, two axially spaced rows of rolling bearing elements between the outer and inner rings;
- the outer ring have a radially outer periphery;
- a main groove defined in the periphery of the outer ring axially between the rows of rolling elements, the main groove having and being defined by edges of the main groove at the periphery of the outer ring;
- a secondary groove axially adjoining the main groove and defined in the periphery of the outer ring;
- the secondary groove having the shape of a circular segment opening wider toward the periphery of the outer ring;
- the secondary groove having a cross section of about one-third the size of the cross section of the main groove.
An antifriction bearing having an outer ring, an inner ring inside the outer ring, two axially spaced rows of rolling bearing elements between the outer and inner rings;
- the outer ring have a radially outer periphery;
- a main groove defined in the periphery of the outer ring axially between the rows of rolling elements, the main groove having and being defined by edges of the main groove at the periphery of the outer ring;
- a deformable material ring in the main groove, the deformable material ring being shaped to protrude beyond the periphery of the outer ring of the bearing.
