RESILIENT MATERIAL INERTIA CENTRIFUGAL CLUTCH Russian patent published in 1998 - IPC

FIELD: mechanical engineering; high-speed drives for transmission of high torques. SUBSTANCE: clutch has driving and driven clutch members with centrifugal lever mechanisms arranged in between symmetrically relative to axis of clutch rotation. Centrifugal lever mechanisms are hinge-connected with clutch driving member by means of pins rigidly secured on disk of driving clutch member. Each centrifugal lever mechanism has bell crank freely fitted by one end on above-indicated pin of driving clutch member, second lever freely fitted on pin rigidly secured on disk of driven clutch member and coupling pin rigidly secured in hole of second lever fork. Bell crank is freely fitted on coupling pin, and flyweight is fitted on cantilever portion of bell crank for longitudinal displacement and fixing on bell crank. Above indicated levers are connected additionally by extension spring. EFFECT: increased reliability and longevity of drive owing to improved smoothness of starting and prevention of impacts loads in drive operation. 2 cl, 5 dwg
