Abstract
A roller seating for swivel motions includes an outer ring, an inner ring and roller rolling in between which are inserted individually between spacers of a flectionally elastic cage. On at least one end of the spacers, one or more projections directed radially outward and/or radially inward have been formed which face, radially and/or axially, a revolving shoulder surface of the outer ring or the inner ring. In order to keep the play of the rollers between the spacers on the circumferential side as small as desired, each projection of the cage is arranged in such manner that it pushes against the circumference of the corresponding shoulder surface of the outer ring or the inner ring and brings the holding surfaces of the spacers against the rollers due to the elastic deformation of the cage.
Claims11
A bearing seating arrangement comprising an outer ring, an inner ring, a bendable elastic cage and rolling elements between said inner and outer rings and positioned to roll in a circumferential direction, each rolling element being installed between essentially axially extending spacers of said cage, the spacers having holding surfaces partially surrounding the rolling surfaces of the rolling elements, at least one of the two ends of the spacers being solidly attached to at least one radially inward and/or radially outward extending projection of the cage, said projection(s) facing a respective revolving shoulder surface(s) of the inner or outer ring, said projection(s) being mounted to be pushed with a directed pre-tensioning force against the circumference of the respective shoulder surface of one of said inner ring or the outer ring, said pre-tensioning force being in a direction to elastically radially dislocate said holding surfaces against said rolling elements.
In a bearing seating arrangement for a bearing having inner and outer bearing rings, a cape having axially extending spacers, and rolling elements positioned to roll between said inner and outer rings and be separated by said spacers, the improvement wherein said spacers are bendably elastic and have holding surfaces engaging said rolling elements, and further comprising means for elastically concentrically flexing said cage about its circumference to hold said holding surfaces against said rolling elements.
