Abstract
A transmission for driving a swivel joint between two elements which are rotatable relative to each other. Cam disks are moved by means of a multiple eccentric, each such cam disk having an outer edge in the form of a closed cycloidal path and being arranged so that it can be rolled off in a central wheel in a positive engagement with a gearing formed by pins or the like. A driving element engages by means of driving pins, with the cam disks by way of bores arranged being in it, the driving element being subdivided into two driving disks which, are spaced from one another and from the cam disks at a distance of at least the central wheel and are combined by means of the driving pins, the driving disks and the central wheel being rotatably movable relative to one another.
