Abstract
The present invention relates to a tightening device for cone belts and the like for use in cone belt transmissions, including at least one preferably driven cone belt pulley which is axially or substantially axially displaceable relative to at least one other, preferably driven cone belt pulley, and a cone belt interconnecting said cone belt pulleys, said tightening device engaging one run of the cone belt by means of a rotary member. The novelty of the invention is that the tightening means includes a preferably spring-loaded support lever arranged adjacent one of the cone belt pulleys and adapted to pivot about a first axis situated substantially parallel with the cone belt pulley shaft and also about an axis oriented generally perpendicular to the first axis, and that a tightening pulley preferably provided with a cone belt groove is fitted at a free end of said support lever in order to maintain the engagement of the tightening pulley independently of any displacement of the cone belt runs caused by the relative displacement of the cone belt pulleys.
