ABSTRACT:
A universal or ball pivot-link chain is guided in two substantially tubular-shaped guide channels and is deflected or turned between such guide channels by means of a driven chain or sprocket wheel. At its circumference the chain wheel possesses a profiled structure formed by recesses or depressions which substantially correspond to the profile or outer contour of the universal link chain. The guide channels extend to the circumference of the chain wheel and form in conjunction therewith a respective transfer or transition region. At each such transfer region the chain wheel protrudes by an amount, essentially corresponding to the depth of the recesses, into the interior of the related guide channel. At such transfer or transition regions the chain links are guided both by the chain wheel and the guide channels. Consequently, there is ensured for a gentle and jerk-free transfer of the chain links from the chain or sprocket wheel to the guide channels and vice versa.
