ROLLER-TYPE OVERRUNNING CLUTCH Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention is designed for stepless regulation of speed and it can be used in impulse transmissions, drives of starters of internal combustion engines and similar devices. Proposed clutch contains concentrically arranged sprocket and race and spring-loaded rollers with screw grooves placed in between. Novelty is that cylinder generating surfaces on ends of rollers are flanked to curve corresponding to load distribution law over length of contact line when rigid roller is pressed into elastic body whose support length is greater than length of roller. EFFECT: increased load bearing capacity and service life of clutch. 1 dwg
