<p>Stageless, adjustable, cone disc-torsional gear for the transmission of positive and negative torques with a tractive circulating fitment over drive and driven cone disc pairs, and control levers for the adjustment and maintenance of the gear conversion. These levers engage either directly or indirectly with the axially displaceable cone discs, and are swivelable around pins of a tension dog adjustable on a spindle located between the cone disc pairs, and are also supported and operable via a position spindle rotatably located outside the cone disc pairs. On the position spindle, dogs are displaceable by means of counter-running threads, and which engage either directly with a pin or indirectly via pins in fork-shaped cut-outs in the control lever. The pins are located by means of slide rings in the fork-shaped cut-outs, the slide rings are centrally divided in the longitudinal direction of the control lever, their respective parts being at a counterposed clearance from each other, and a slit formation running in the longitudinal direction of the control lever connects with the cut-out. The control levers are tightened in next to the cut-outs by a cross-ways running tightening screw, whereby the counterposed distance between the parallel jaws of the cut-outs is adjustable. Next to each dog two draw screws provided with nuts, axial to the position spindle, are unrotatable relatively to the dog, and the tension is so deviced that the axial force they produce is at least 30% of the maximum torque-produced axial force component between the cone discs and the position spindle.</p> |
