CRANK MECHANISM WITH CONTROLLABLE STROKE OF SLIDER WITH OPERATING AND STOPPED MAIN DRIVE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; crank mechanisms of reciprocating drives at adjustable stroke of slider of stopped and operating mechanism. SUBSTANCE: tenon of crankshaft 5 is received by hole of bush 4 and driven wheel 3; axis of rotation of wheel 3 coincides with axis of crankshaft and is parallel to axis of tenon; tenon of crankshaft screw pair. Rotation from stem-pinion 2 is transmitted to wheel 3, crankshaft 5 and to bush 4 connected with its tenon; bush 4 sets in motion connecting rod 6 and slider 7. Proposed mechanism may be used in various industries including petrochemical and oil refining industries, manufacture of pumps, proportioning technique for liquids and gases. EFFECT: enhanced reliability. 1 dwg
