CLUTCH EXPANDING PLANT Russian patent published in 2008 - IPC B21D41/02 B29C43/16 B21D39/20 B21D31/04 

FIELD: mechanical engineering; manufacture of clutches.

SUBSTANCE: proposed plant contains housing, rod, pair of truncated cones, segments with guide slots, and drive. Said truncated cones are made with equal taper angles, being installed for axial displacement and pointed to each other by smaller bases. Segments with guide slots are installed for radial displacement. Truncated cones are provided with locks installed for travel in guide slots of segments and engagement with their inner surfaces. Plant is furnished with two bushings with slots and rack mechanism. Rod is made in form of drive shaft and is installed on housing for periodical demounting. One end of rod is connected with drive by splined joint. Truncated cones are installed on rod for axial displacement by means of thread. One truncated cone has right-hand thread and the other, left-hand thread. End faces of larger bases of truncated cones are provided with cylindrical projections with splines designed for fitting said projections in slots of bushings for axial displacement and engagement with inner surfaces of bushing slots. One of said bushings is rigidly secured on housing. Second bushing is secured coaxially with rod in rack mechanism for axial displacement.

EFFECT: possibility of expanding of clutch made of different materials.
