Abstract: A sliding ball joint comprising a joint outer part having inclined ball raceways which are formed on an inner periphery and which are arranged about an axis of rotation of the joint outer part, a joint inner part having inclined ball raceways, which are formed on an outer periphery and which are arranged about an axis of rotation of the joint inner part. Ball raceways of the joint outer part and of the joint inner part face each other in pairs and have angles of inclination opposite to each other, one ball per ball raceway pair, and a cage, which is arranged between the joint outer part and the joint inner part and having windows, in which the balls are accommodated.

Abstract: A tripod joint including an outer joint member with several axially extending elongate tracks; an inner joint member with several radial axle journals distributed over the outer circumference thereof; at least a number of rollers corresponding to the number of axle journals, where the roller is respectively pivotably retained with a central bore on the associated axle journal and is in engagement with the elongate tracks, where the roller is accommodated in the associated track so as to be displaceable in the axial direction of the outer joint member; where each axle journal includes on its circumference two outer diametrically opposed spherical end faces for engagement into the bore, where the bore has a cylindrical portion for engagement with the spherical end faces in order to support the roller so as to be displaceable relative to the journal, and at least a constricted portion that is adjacent thereto in the axial direction, while forming a continuous transition, on one side of the cylindrical portion, a

Abstract: The invention relates to a tripod joint (1) comprising the following: an outer joint member (2) with several axially extending elongate tracks (4) formed therein and distributed over the inner circumference thereof; an inner joint member (3) with several radial axle journals (5) distributed over the outer circumference thereof; at least a number of rollers (6) corresponding to the number of axle journals (5), wherein the roller (6) is respectively pivotably retained with a central bore (20) on the associated axle journal (5) and is in engagement with the elongate tracks (4), wherein the roller (6) is displaceable in the associated track (4) in the axial direction of the outer joint member (2); wherein each axle journal (5) comprises on its circumference two outer diametrically opposed spherical end faces (16) for engagement into the bore (20).

Abstract: A method for configuring a drive to control the operation of a pump in a sewage system is disclosed. The method comprises measuring at least one parameter of the sewage system; using the measurement of the at least on parameter to create an algorithm for the drive to control the operation of the pump; and configuring the drive to use the algorithm to control the operation of the pump.
