  • Patent number: 9011017
    Abstract: 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 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. 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, the 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).

  • Patent number: 8956052
    Abstract: A sealed anti-friction bearing (1), including an annular sealing washer (11, 12) which seals a rolling-body chamber (7) in the axial direction, wherein the sealing washer (11, 12) has a fastening section (14) for connecting it fixedly to a bearing ring (2) of the anti-friction bearing (1) so as to rotate with it, and wherein the sealing washer (11, 12) is anchored with its fastening section (14) in a circumferential groove (22) of the bearing ring. According to the invention, it is provided that the fastening section (14) has a first clamping element in the form of a barb (19) and a second clamping element in the form of an annular bead (20), and that the barb (19) and the bead (20) enter into a non-positive connection with oppositely lying surfaces of the groove (22).

  • Patent number: 8794841
    Abstract: A toroidal bearing (1) including a multiplicity of barrel-shaped rolling bodies (7) which roll about a bearing axis (8) between an outer ring (2) having a raceway (3) and an inner ring (4) having a raceway (5) is provided. According to the invention, on a circumferential surface (9) facing away from the raceway (3, 5) thereof, the outer ring (2) and/or the inner ring (4) has at least one lubricating groove (10), wherein the lubricating groove (10) is connected to the raceway (3, 5) via at least one lubricating bore (11).

  • Publication number: 20060165333
    Abstract: A barrel-shaped bearing which comprises an external ring and an internal ring, at least one row of barrel-shaped rolling bodies arranged therebetween, the cage in the form of a disk which turns together with the rolling bodies, engages inside a peripheral groove around each rolling body and is provided with recesses corresponding to the number of the rolling bodies of the one row arranged on the external periphery of the cage. The total rolling surface of the internal ring is embodied such that the cross section thereof is concave along the entire axial length of the rolling body. The smallest distance between both sides of the cavity of the disk-shaped cage in the area of the external periphery thereof is less than the diameter of a rolling body in the area of the peripheral groove thereof.

  • Patent number: 6926446
    Abstract: Radial self-aligning rolling bearing including an outer ring, an inner ring, and balls which are arranged to roll in the raceways of the rings, and also spherical rollers together as rolling elements, which are all guided in a cage. The balls are larger in diameter than the spherical rollers, so that the balls exclusively take up the entire bearing load when the bearing load is small and both the balls and the rollers take up a larger bearing load.

  • Patent number: 6055405
    Abstract: A printer or copier has an intermediate carrier for applying toner to the recording medium. Used toner is scraped off the intermediate carrier and carried away by a conveyor helix. The conveyor helix is of a spring wire and a resistance element is provided extending between coils of the conveyor helix to intermittently catch and release the spring wire so as to cause wobbling of the conveyor helix and prevent sticking of the used toner.
