Drive mechanism for pumps, including a pump rotor mounted in a pump chamber, a pump cover covering the pump chamber. The cover has an axially projecting shoulder with a housing bore passing through from the pump rotor to the outside, and a shaft passing through the housing bore. The shaft is connected in a torsion-proof manner at its inner end to the pump rotor and at its outer end by way of a coupling element to a drive wheel. The shaft is supported in an inner bearing seated in the housing bore while the drive wheel is supported on an external bearing. A plate 7 is provided, which is separate from the pump cover 5 and which can be mounted on the housing or the like in various positions. The bearing 9 for the drive wheel 10 is supported on the plate 7 in a manner to allow freedom of rotation.

Drive mechanism for pumps

A water pump having a water pump housing, a housing flange mounted on the water pump housing, and a pump rotor rotatably journaled in the housing. A hollow stud projects axially outwardly from the flange, a drive and bearing assembly for supporting the pump rotor comprising a roller bearing supported on the outer peripheral surface of the hollow stud, and a pulley rotatably supported by the roller bearing on the hollow stud of the housing flange. A shaft supports the pump rotor and passes through the hollow stud. A coupling element connects the pulley to the shaft in a torsion-proof manner and simultaneously centers the shaft whereby the roller bearing is tightened to eliminate axial play.

Drive and bearing for water pump

A drive device for pumps consists of a drive pulley to drive a shaft. The shaft assembly includes an inner bearing seated in the housing bore, an outer bearing seated on a neck of a pump cover, a cover disk with an outer edge, covering the outer bearing and the neck of the pump cover laterally from the outside and is connected to the drive pulley, and a center of the shaft, a spring for the automatic play eliminating adjustment of the radial and axial load-supporting outer and inner bearing.

Drive device for pumps

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 cage for a ball bearing, especially for an inclined ball bearing, is comprised of two side rings connected together by webs, with one of the side rings being outside of the pitch circle and the other side ring being inside of the pitch circle. Circumferentially resilient axially extending projections are provided extending from one of the side rings toward the other, radially inwardly or outwardly of the pitch circle, and recesses are formed by the webs and projections in the regions of minimum spacing between the balls.

A universal joint for rotatory drives such as are for example used in motor vehicle construction. To improve the life of the bearings, asymmetrical indentations are provided on the yoke arms, or the yoke arms have tangentially directed sections in which the bearing bores are disposed. As a result, the universal joint is subjected to load, and there is no deformation of the bearing bore or unacceptable cramping of the bearings.

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. This end face has a diameter that is equal to or greater than the diameter of the radially inner edge of the annular grooves and smaller than the diameter of the radially outer edge of the annular groove.

Support means for trunnions in fork eyes of universal joints comprising a bearing bushing consisting of a generally cylindrical sleeve section and a bottom section closing one axial end of the sleeve section adapted to axially support the trunnion and a plurality of cylindrical rollers arranged in at least two side by side rows. The rollers engage and roll between outer races in the bore of the sleeve section and inner races on the trunnion. The sleeve section has a constant uniform diameter over its entire outer peripheral surface and has outer races formed in its bore section which are offset in steps radially inward towards the bottom section. The inner races are disposed in side by side array on the trunnion and of the same diameter without offset.

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.

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.
