LINK MECHANISM Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: link mechanism has crankshaft and rocker arm, which are mounted on column and coupled with connecting rod, and two slides. One slide is pivotally positioned on rocker arm in guide mounted on other slide, which is, in its turn, positioned in column guide. Mechanism for converting reciprocating progressive motion into reciprocating rotary motion has balls with retainers fixed on sides of first slide and adapted for engagement with slots in guides of second slide. Link mechanism is further provided with auxiliary crankshaft, connecting rod and two slides, which are arranged in opposed relation and in symmetry with respect to main crankshaft, connecting rod and two slides. Crankshafts are provided with toothed gears, between which drive gear is positioned. Third slide is positioned on other end of rocker arm. Both auxiliary slides are arranged similar to main slides. Usage of two crankshafts in construction allows torque value and number of output kinematic circuits to be increased. EFFECT: simplified construction and enhanced reliability in operation. 1 dwg
