LINK-SLIDE MECHANISM Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: link 5 is provided with additional groove opposite to the main groove. Additional slide 12 is received in the additional groove. The additional slide is pivotally coupled with one ends of rockers 15 and 16. Connecting rods 13 and 14 are pivotally connected with the other ends of rockers 15 and 16 and rigidly secured to eccentric 3 and eccentric bushing 4. Pins are rigidly connected to slides 6 and 12. The roller bearings are mounted on the pins. The drive of slides 6 and 12 is made up as the input shaft set in the stand and ellipse race rigidly connected with the shaft and having ellipsoid rim 20. The rim is defined by ring groove 19 of ellipse-like profile made over the periphery of one of the race faces. Pins of slides 6 and 12 of the bearings are received in ring groove 19. When the input shaft is in rotation together with the race, slides 6 and 12 move in grooves of link 5 synchronously and toward each other. The transmission ratio is determined by eccentricity of eccentric 3 and eccentric shaft 4 as well as the length of rocker 7 and 8, 15 and 16 and connecting rod s 9 and 10. EFFECT: enhanced reliability and efficiency. cl, dwg
