HYDRAULIC SYSTEM FOR SYNCHRONIZING OPERATION OF TWO SERVOMECHANISMS Russian patent published in 2002 - IPC

FIELD: systems for synchronization of operation of two servomechanisms. SUBSTANCE: hydraulic system is in the form of two hydraulic cylinders whose cavities through throttling flow divider and reversing hydraulic distributor are communicated with pump and drainage. Hydraulic system includes apparatus for realizing mechanical feedback according to motion of rods of hydraulic cylinders. Said apparatus engages with throttling flow divider and it includes gear-rack transmissions whose toothed racks are mounted on rods of hydraulic cylinders and gear wheels are kinematically joined one with another through safety coupling in such a way that gear wheel at side of one hydraulic cylinder is mounted on stationary support and gear wheel of other hydraulic cylinder is arranged in housing movably mounted on toothed rack and engaging with throttling flow divider. Gear-rack transmission at least of one hydraulic cylinder is in the form of worm pair, namely: worm mounted on rod of hydraulic cylinder with possibility of rotation by action of its own drive unit and worm gear that is kinematically joined through clutch coupling with gear wheel of gear-rack transmission arranged at side of second hydraulic cylinder. EFFECT: simplified design, enhanced reliability of system. 4 dwg
