MECHANISM FOR CONVERTING MOTION Russian patent published in 1998 - IPC

FIELD: gear trains and leverage mechanisms for converting rotary motion into reciprocating motion; internal combustion engines and drives of working members of machines. SUBSTANCE: mechanism includes input members in form of reduction gear consisting of bevel gears; sun gear of reduction gear is secured on input shaft and side gears thrown into engagement with sun gear are mounted rotatably on one fixed shaft at right angle. Ends of shaft located at distance from side gears of reduction gear carry sun gears of planetary mechanisms which are used as transfer member; their satellites are mounted rotatably on shafts rigidly secured on outer end faces of side gears of reduction gear at distance form axis of fixed shaft equal to diameter of satellite. Pins are mounted at eccentricity on outer end face of one of satellites; they are articulated wit output members made in form of connecting rods with pistons. On opposite members, pins are mounted in counter-phase. EFFECT: enhanced efficiency of engine due to multi-member construction at periodically changing speed of output member. 2 cl, 3 dwg
