Device for mounting a radial rolling bearing

A device for mounting in a bore of a support a radial rolling bearing having rolling elements, comprising an elastically yieldable collar in which is engaged a thin sleeve which serves as a raceway for the rolling elements and has an elasticity enabling it to deform radially under the action of forces transmitted by the rolling elements, said sleeve being preformed in accordance with an irregular profile which defines circumferentially of the sleeve alternately cylindrical segments having an inside radius for defining a passage with an inner raceway for the rolling elements affording a usual radial clearance for the rolling elements and inwardly offset cylindrical segments for defining a passage with said inner raceway of reduced radial width for the rolling elements, said elastically yieldable collar comprising an elastically yieldable thin-walled ring, the elasticity of the thin-walled ring being due to the presence in the ring wall of at least one curved portion which defines at least one inwardly convex surface bearing on the outer surface of the sleeve and at least one outwardly convex surface bearing against the inner surface of the bore of the support.
