LEVER-GEAR MECHANISM FOR CONVERTING ROTARY MOTION INTO COMPOUND MOTION Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed invention relates to converters of rotary motion of driving member into vibratory motion with displaced trajectory and into rotary reciprocating motion. Mechanism has housing ands bevel planetary gear train consisting of central wheel and hollow carrier installed in housing for rotation. One planet pinion is installed on carrier. Planet pinion comes into meshing with central wheel. Crank rigidly connected with planet pinion is connected by one end with connecting rod. Other end of connecting rod is coupling with output slider installed in carrier space. Rocker is installed on crank shaft. Additional connecting rod is provided which is hinge coupled with crank and rocker. Mechanism has driven shaft and bevel gear train. Driving member of gear train is made in form of gear sector and is installed on rocker hub through overrunning clutch. Main connecting rod is made in form of two forks interconnected by slider. Output slider and connecting rod slider can be rigidly connected with forks by means of two control pins. Two additional control pins connect driven shaft with driven wheels of bevel gear train, rocker axle-shaft and gear sector hub. EFFECT: enlarged kinematic capabilities. 1 dwg
