CAM-GEAR-LEVER MECHANISM FOR PERFORMING PERIODIC TURN Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: built-up crank consists of two parts: 1 and 1′; flexible member 8 located between parts of crank is used for connecting them. During rotation of crank, cam 10 acts on retainer 9, owing to which driven wheel 7 is free to rotate about its axis. When force transmitted along crank is less than force of selected preload of flexible member 8, parts 1 and 1′ of crank move as a single link. During positive stop of wheel 7, excess of preload force of flexible member 8 sets parts 1 and 1′ of crank in relative motion. EFFECT: enhanced dynamic characteristics of mechanism and improved construction. 1 dwg
