TWIN SLIDE-ROCKER MECHANISM Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: pivot 11 of tree-arm lever 4 with stand 1 is at the same distance from the second and third tops of three-arm lever 4. The lengths of carriers 5 and 6 are equal to the distance between the second or third tops of three-arm lever 4 and pivot 11 of connection of three-arm lever 4 with stand 1. Four counterweights are rigidly secured to carriers 5 and 6, to crank 9 and to tree-arm lever 4 respectively. When crank 9 rotates, slides 7 and 8 moves over the straight- line guides 2 and 3 toward each other, the speed of the slides being the same. Carriers 5 and 6 move in the same direction and plane. EFFECT: enhanced reliability. 1 dwg
