  • Patent number: 4437214
    Abstract: In a non-machining method for manufacturing a solid-bottomed or internally flanged bearing race, especially for rolling contact bearings, the starting material is in the form of a band. For the economical manufacture of this bearing race with an annular groove of extremely precise cross-sectional shape which reduces the wall thickness of the bearing race, and which is situated at the transition from the bottom or flange portion to the race portion, a flat roundel is first stamped from the band. Then a concentric annular groove is worked into one of the planar surfaces of the roundel, while the opposite planar surface thereof is supported on a planar supporting surface. Lastly, the roundel is deep-drawn in a die to form a bearing race having a solid bottom. The end face of the drawing punch concentrically engages the roundel's planar surface that is encompassed by the annular groove.

  • Patent number: 4435890
    Abstract: A method for making complementary pairs of race rings for rolling bearing assemblies from a unitary metallic base component formed with the raceways for the rings consisting of the steps of:a. forming at least one annular separation seam in the metallic base component defining a bridge which can be severed to form the paired bearing race rings;b. hardening the metallic base component;c. machining the raceways of the rings simultaneously or successively;d. plastic coating the base component to form housing sections adjacent the bearing and side surfaces of the race rings exposing the raceways and separation seam; ande. separating the base component at the bridge to form the finished race rings.

  • Patent number: 4423911
    Abstract: A rolling bearing assembly for lengthwise movement with respect to a shaft has an outer sleeve with internal races, and a cage guiding endless rows of rolling bodies in the bore of the outer sleeve. The cage has a slit extending axially and radially therethrough, and the cage portion aligned with the slit is radially moveable, so that an entire row of rolling bodies adjacent said slit may be radially moved into a race formed in a shaft in the bearing. The sleeve may have a second slit spaced from the first slit. The second slit may be only partial, to define a region of bending, or may extend completely through the outer sleeve to define a segment, with the first slit, that is radially moveable.

  • Patent number: 4421363
    Abstract: A rolling bearing for lengthwise movement between a sliding element and a rail element has a cage arranged between the sliding element and the rail element, and at least one endless row of rolling bodies in the cage. The loaded rolling bodies of each row roll between longitudinal races of the slide element and the rail element, and the cage has longitudinal guides for loaded rolling bodies and unloaded rolling bodies, as well as turnaround guides for interconnecting the loaded and unloaded guides at each end. An elastic guide element is mounted on at least one side of one of the guide tracks to resiliently urge the rolling against the guide tracks.

  • Patent number: 4412372
    Abstract: The present invention is a method for the manufacture of bearing rings ruptured along an arrow-shaped partition line for antifriction bearings or similar devices. According to the invention a radial bore is introduced through the middle of the ring transversely of the bearing axis, and in the opposite end faces are introduced V-shaped notches which are displaced in relation to the radial bore in a circumferential direction. The bearing ring is supported on one end and ruptured first on that end by a force directed against the opposite end. The ring is turned over and again ruptured similarly until an arrow-shaped partition line extends from the radial bore to the notches.

  • Patent number: 4411478
    Abstract: A rolling bearing for lengthwise movement along a shaft comprised of an outer sleeve having a plurality of races therein for rolling bearings, a cage being provided to guide the rolling bearings. A sealing ring is provided at each end of the assembly, the sealing ring having lips extending radially inwardly to contact the shaft. The sealing lips are thin and elastically bendable, and are mounted to enable bowing thereof into free spaces on opposite sides thereof, depending upon direction of lengthwise movement of the shaft. As a consequence, for small movements of the shaft, the sealing lips cling to the shaft and become bulged, rather than sliding along the shaft.

  • Patent number: 4399898
    Abstract: The present invention is a device for securing a shaft or the like in a hub, wherein an annular groove is provided on the shaft or in the hub to accommodate an elastic securing ring of round cross-section. A shoulder is provided on the hub or shaft radially facing the annular groove and the hub or shaft has an adjusting member displaceable in axial direction with a conical face axially facing the shoulder. This face together with the shoulder forms an annular recess widening towards the opening of the groove. The floor of the annular groove on the side of the adjusting member is at a radial distance from the shaft or hub at least as great as the thickness of the securing ring.

  • Patent number: 4397802
    Abstract: A ball bearing adapted for axial movement on a shaft is comprised of a cage having guideways defining endless paths having axially extending portions for loaded and unloaded balls, and semicircular end portions. An outer sleeve surrounds the central portion of the bearing and defines races for balls in the endless paths. End rings on the axial ends of the bearing radially outwardly cover the semicircular quideway portions. The semicircular guideway portions have outwardly convex bottoms, and the end rings have concave recesses in their inner surfaces aligned with the semicircular guideways. The convex portions of the guideways and the concave portions of the recesses have common centers of curvature extending parallel to the bearing axis and displaced outwardly therefrom.
