FRICTION COUPLING Russian patent published in 1999 - IPC

FIELD: machine engineering, namely drive mechanisms of hydraulic pulsation presses. SUBSTANCE: friction coupling includes driven friction disc, driving semicoupling mounted on shaft of motor, pressure ring, at least there balls contacting with pressure ring, spring for forcing balls to pressure ring. Driven friction disc is mounted on driven fly-wheel. Pressure ring has bead and it rests upon driven friction disc. Balls are arranged in radial grooves of driving semicoupling with possibility of sliding motion relative to pressure ring. Coupling also includes profiled ring for forcing balls to pressure ring by means of spring; said ring is mounted in such a way that balls may slide relative to it. Friction disc is mounted with possibility of sliding along inner surface of fly-wheel cavity. EFFECT: stable torque transmission from motor to fly-wheel for speeding up at predetermined time period. 3 cl, 1 dwg
