RODLESS MECHANISM FOR CONVERTING RECIPROCATION INTO ROTATION AND VISE VERSA Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism has gears 13 and 14 mounted on cranks 11 and 12, respectively. The diameter of the pitch circle of the gears is the sane. One of the gears is interposed between crankpin 5 of the crank shaft and gear 21 mounted on main journal 7 of the crank shaft that are mounted inside the housing for permitting rotation parallel to the axis of rotation of cranks. The mechanism also has connecting shaft 17 provided with gears 15 and 16 that engage gears 13 and 14 of cranks 11 and 12 and output shaft 18 and additional gear 20 of internal engagement that engages one of the gears of the connecting shaft. EFFECT: improved design. 1 dwg
