MACHINE-ROCKER WITH COMBINATION BALANCING Russian patent published in 2000 - IPC

Abstract RU 2153102 C2

FIELD: oil production through boreholes. SUBSTANCE: machine has pillar, double-arm balancer, cross-piece, connecting rod, cranks and drive. Balancing is performed by means of counterweights positioned on every crank and loads. Loads are arranged on cross-piece so that its mass center is not aligned with axis of hinge connection of cross-piece and balancer. With cranks in vertical position, balancing load on cross-piece creates moment relative to axis of crank rotation different from zero. Machine makes it possible to reduce number of variations of resulting moment signs per turn of crank from two to one. EFFECT: extended service life of drive. 2 dwg
