  • Patent number: 4438989
    Abstract: A ball bearing has inner and outer raceways, and a row of balls mounted to roll between said raceways. The outer raceway is defined by an outer ring axially held in position by flanges of an outer sleeve. An axially extending space is provided between the outer ring and one of the flanges of the outer sleeve, for receiving a bearing element determined by the use in which the bearing will be placed. Examples of the bearing function-defining element are an annular seal, a corrugated annular spring, and the combination of a corrugated annular spring and a rigid washer.

  • 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: 4435889
    Abstract: A process and apparatus for forming a cage part, for a ball bearing, wherein the cage parts are annular with alternate flat portions and ball receiving recesses. The cage parts are formed by pressing the rings from cage material such as steel. The flat portions are formed with axially extending rivet pins or holes for receiving the rivet pins of another cage part, in order to enable fastening of the cage parts together. The rivet pins are formed by pressing operation at the time as forming the cage part, by the flowing of the material of the cage part into recesses in a die.

  • Patent number: 4419901
    Abstract: A device for measuring axial force in a shaft journalled or mounted with two roller bearings arranged side by side in a housing, such measuring occurring by means of wire strain gauges or the like. The inner ring of the roller bearing on the shaft side engages a shaft shoulder, and the end faces of the roller bodies of the roller body row facing the bearing cover are supported by the flangeless inner ring of the adjoining roller bearing against a flanged ring or angle ring which is disengageably arranged on the shaft. This device is especially intended for wheel-set shafts of rail vehicles during travelling operation. Those end faces of the roller bodies of the two roller body rows facing each other are supported on a central flanged ring which transfers force and is movable in the direction of force when force is applied.
