In a drive device for pumps consisting of a pump impeller mounted in a pump chamber, a pump cover covers the pump chamber and has an extension and a bore passing from the pump chamber to the outside. A shaft is connected at its inner end to the pump impeller and at its outer end in a torsion-proof manner by way of a coupling element to a drive wheel. A bearing supports the shaft and drive wheel in the housing bore and extension respectively. The coupling element is formed by an external edge rigidly connected to the drive wheel and covers the outer bearing and the extension laterally on the outside. A cover plate with a center section connects in a torsion-proof manner to the shaft, and is adjusted to elastically adjust the cover plate relative to the pump cover either inward toward the pump chamber or outward away from the pump chamber, thereby providing for automatic adjustment of the radial and axial load-supporting bearings means to remove their play.

A method for assembling bearing rings in an elongated sleeve member consisting of the steps of forming a roller shell with three sections of varying wall thicknesses separated by angular circumferentially extending shoulders, deforming the shoulder between the middle section and one end section to form a ring-shaped radially, inwardly directed projection by axial displacement of the shoulder. A bearing ring is inserted in the interior of the shell member so that one axial end face engages the first radially oriented projection formed and deforming the shoulder between the middle section and the other end section to form a second radially inwardly directed projection by axial displacement of the shoulder which confronts the opposite axial end face of the bearing ring.

An arrangement for adjustment of a rolling bearing which is radially and axially movable inside a sleeve. A helical spring is arranged with prestress between the base of the sleeve and a side surface of the outer ring of the rolling bearing. The terminal windings of the spring are radially restrained by form-locking with projections on the base and the side surface.

A rotation-damping rolling bearing is provided with a damping element between a cover or sealing disk and a row of rolling elements. The damping element can be integrally formed with a cover disk, vulcanized on the support body of the sealing disk, integrally formed with the support, or connected to the sealing disk separate from the support. The sealing disk is provided with a flexible sealing lip. The damping element contacts the rolling bodies with axial prestress.

A method and apparatus for manufacture of a rolling body directly on a bearing, comprising a hub, a roller sleeve, an annular portion joining the hub and roller sleeve, and reinforcing ribs on either side of the annular portion. Injected material fills the recesses for forming the reinforcing ribs from two directions: a primary flow radially inwardly directed from the mold portion for forming the roller sleeve and a secondary flow radially outwardly directed from the mold portion for forming the hub. The total cross-sectional area of the recesses for forming the reinforcing ribs is adjusted with respect to the circumferential cross-sectional area of the mold portion for forming the annular portion so that the fronts of the primary and secondary flows meet in the recesses. Pressure-release openings are arranged to communicate with the recesses at points in the area at which the meeting of the flow fronts occurs. The junctures resulting from the meeting of the flow fronts are thereby formed along the reinforcing ribs.

A bearing unit for a rotating component, such as a toothed gear or guide pulley, with an integrated pump consists of a housing with a pump chamber defined therein, a pump rotor installed in the pump chamber, a support pin having an end supported in the housing, and a bearing ring rotatably mounted on the support pin. The bearing unit is mountable on a support surface of an associated machine element, such as an engine block by means of a flange on the housing. The pump rotor and the rotating component are securely mounted on the outer surface of the bearing ring in mutual abutting relationship. The pump rotor is disposed between the housing flange and a web portion of the rotating component. The rim portion of the rotating component circumscribes the pump rotor. A sliding sealing ring is provided between the housing or housing ring and the rotating component.

In a method for fixedly mounting a machine element such as a bearing on a smooth shaft, the material of the shaft is displaced by forcing a stamping tool into an outer surface of the shaft, in a direction at an angle to the axis of the shaft.

An hydraulically operated clutch release has an annular piston hydraulically moveable in an annular chamber. A felt ring is mounted on a shoulder of the piston away from the chamber, to engage the bore surface of the chamber, and a holding ring is snapped onto the end of the shoulder to hold the felt ring on the shoulder. An extension of the holding ring forms a seal with the bore on the chamber, and defines, with the felt ring a dust catching recess.

The invention relates to an hydraulic release arrangement for vehicle clutches or the like and consisting of an annular cylinder axially expanding in the application of the clutch and a release bearing that is affixed to the annular cylinder without special guidance. The annular cylinder is constructed of coaxially arranged tube-shaped spring metal bellows with lateral self-sealing connection rings. Alternatively, a spring metal bellows with a U-shaped profile is used.

Means for securing a machine element such as a bearing assembly on a shaft member or the like provided with an annular groove comprising an angular ring (14) having a radially outwardly directed leg portion (15) which abuts against an axial end face of the inner ring component to be secured and an axial leg portion (16) which is pressed into the annular groove (17) of the shaft or the like at least at a plurality of circumferentially spaced locations about its periphery.
