A pendulum tensioner, comprising a first and second tensioning arm, and a bearing sleeve configured to attach to a generator housing, wherein the bearing sleeve forms a sliding channel together with a locking sleeve, in which one of the tensioning arms is rotatably positioned with axial play.

A nut () for a planetary roller screw drive is provided. A sleeve () which is produced by metal forming is provided, and two rings () that lie at a fixed distance with respect to each other in the axial direction are provided in this sleeve. In order to engage planets (), the one ring () has the one groove profile (), and the other ring () has the other groove profile ().

Nut of a planetary roller screw drive, and method for producing such a nut

Method for the production of a spindle nut () of a spherical thread drive mechanism, whereby the spindle nut () has at least one screw-shaped track () formed as a single piece on its inner circumference, whose threads () are limited by shoulders (). The shoulder () is interrupted by a deflecting recess () at at least one deflecting position, in order to deflect balls () out of one thread into an adjacent thread (). The method includes locating a tool arbor () in a hollow blank (), whereby the tool arbor () has on its outer circumference a counter profile of the screw-shaped track () and a projecting part () for each deflecting recess. A tool operates on and reshapes the blank () from the exterior by exercising radial forces (F), whereby during the reshaping process the inner circumferential surface of the blank () is shaped according to the counter profile and to the projecting part () of the tool arbor () such that the screw-shaped track () and the deflecting recess () are formed.

A device for the angular adjustment of a camshaft relative to a crankshaft of an internal combustion piston engine, particularly a vane-type adjuster comprising a stator and a rotor arranged coaxially to the stator, vanes of the rotor being pivotable by oil pressure in pressure chambers defined by radial walls of the stator. Fabrication work is reduced compared to stators and rotors made by sinter pressing by the fact that the stator and the rotor are comprised respectively of a stack of stator blanks ( &prime;) and a stack of rotor blanks ( &prime;), said blanks are made preferably by punching and are firmly connected to one another.
