Abstract (en)
[origin: WO2012152519A1] The invention relates to a radial rolling bearing (10) with rolling bodies (24) which are received in at least one cage (26, 28) and which are arranged between an inner ring (20) and an outer ring (22). The radial rolling bearing (12) is designed to be radially separable, and the radially multipart inner ring (20) can be fixed on a shaft (16) using two clamping rings (36, 38) which are attached to the axial ends of said inner ring. According to the invention, the inner ring (20) is designed without rims on the axially outer sides, and the clamping rings (36, 38) take on the function of inner ring rims, said rolling bodies (24) running against inner run-on surfaces (50) of the clamping rings (36, 38) in the axial direction. On the basis of the at least partial positioning of the clamping rings (36, 38) axially below the cages (26, 28) or the outer ring (22), the clamping rings (36, 38) take on two additional functions in addition to the actual clamping ring main function of fixing the inner ring (20) on the shaft (16). Firstly, the clamping rings (36, 38) form a cage guide in the radial direction, and secondly, said clamping rings assist the axial guiding of the rolling bodies (24) by means of the inclined inner run-on surfaces (50). The radial rolling bearing additionally has a reduced axial installation dimension on the basis of the special arrangement of said clamping rings (36, 38) in the radial rolling bearing.
