FIELD: mechanical engineering. SUBSTANCE: device has housing with two sleeves mounted movably inside it; sleeves are provided with retainers which keep them from axial displacement. Mounted in sleeves are crank and slider which are provided with gear wheels forming internal gearing. Crank is made in form of shaft. Slider is made in form of barrel. Shaft of crank is hollow. Mounted eccentrically in crank for axial displacement is bush with main and additional pins. Connected with pins are main and auxiliary connecting rods which are eccentrically secured by means of hinges: main connecting rod is secured on slider and additional connecting rod is secured on cap of crank shaft. EFFECT: increased amplitude of reciprocating motion of output member by two times due to introduction of additional pin and auxiliary connecting rod. 1 dwg
