Abstract:
A transmission has a housing having a main axis with a retaining element fixed in the housing and forming a set having a predetermined number of radially extending and angularly equispaced guides. An output element rotatable in the housing about the axis is formed with an array having a number smaller than the predetermined number of radially inwardly open recesses axially adjacent the guides. An input element rotatable in the housing about the axis has a radial outer and generally circular peripheral surface centered on an axis radially offset from the main axis. Respective transmission elements radially displaceable in the guide grooves between inner and outer positions each have a shaft extending substantially parallel to the axis with a guide section engaged and radially shiftable in the respective guide groove, a driven section engageable in the recesses, and a drive section radially engageable with the input-element surface.

Abstract:
A process and apparatus for producing metal balls from a cylindrical strand material, with two rolling jaws which are displaceable relative to one another and of which each forms a shaping groove which extends in a direction of displacement, wherein the jaws are located displaceably relative to one another such that U-grooves, which are located opposite one another on the opening side, form a shaping channel, a blank being rolled, as a result of displacement of the channel walls relative to one another, on its passage through said shaping channel. The blank is fed by a feed device, via a feed channel, to an opening of the shaping channel and is cut off from the strand, by a cutting tool, beforehand, wherein the wire (1) is inserted through a shearing opening (2), which opens transversely into the feed channel (7), until it reaches a stop (3), which is located opposite the shearing opening (2), and is cut off by a shearing cutter (5), which is associated with the shearing opening (2), in the direction in which the feed channel (7) progresses. The stroke of the shearing cutter (5) advances a plurality of wire sections (6), which are located parallel to one another in the direction of a mouth opening of the shaping channel, wherein once the shearing stroke has ended, the foremost wire section (6) is fed to a shaping operation.
