A system for preloading the bearing of a cooling water pump for motor vehicles. The pump comprises a shaft and an impeller mounted on one end of the shaft and, an outer bearing ring surrounding the shaft. An axial face seal is mounted on one projecting end of the shaft operable bearing ring and to tension spring-loaded sliding rings with a predetermined contact pressure against each other. The outer axial end face of the axial face seal is aligned with the axial end face of the shaft to simplify and insert the same preloading of the bearing for assemblies put together by mass production techniques.

System for preloading the bearing of a pump assembly

Bearing design for the drive gear and the pump impeller of a cooling water pump for motor vehicles, with a shaft, which is installed so that it can rotate by means of two rows of balls in an outer bearing ring, and which projects on both sides beyond the outer bearing ring, characterized in that the shaft (12) is produced by the extrusion method and has a wall (20) separating chambers or compartments extending inwardly from opposing ends of the shaft, the wall is located on the drive side outside the rows of balls (24).

Bearing assembly and method for making a component thereof

Liquid pump assembly comprising a pump housing having a pump chamber, a drive shaft in the pump chamber mounting a pump rotor, a pump chamber cover and a molded member (12,18) partially defining the shape of the pump chamber (8) located on the inside surface of the pump cover (1).

Liquid pump

Pulley for driving the shaft of a water pump, especially a pump for the cooling system of an internal combustion engine, the shaft being designed to be integral with a pulley body carrying the rim of the pulley, characterized in that the rim (15, 25, 31, 37) is designed as a sleeve and is attached to the pulley body (13, 22, 29, 39) in a form-locking or friction-locking manner.

Pulley for drive shaft for a water pump and method for making the same

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.

Drive mechanism for pumps

A bearing on a shaft is separated from the bore of a housing by an intermediate sleeve. The sleeve has an annular recess in its end surface, the end surface being spaced from the shaft. A sealing element extends radially in the annular recess and axially between the shaft and the intermediate sleeve. The axially extending arm of the sealing element has a flange extending behind a radially extending surface of the intermediate sleeve to axially hold the sealing element, with play, to the intermediate sleeve. The sealing element is mounted with prestress on the shaft, to rotate therewith during operation.

Contact free seal for a bearing

A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.
