HYDRAULIC RESOLVER FOR STABILIZING SUMMED SPEED VECTOR OF TWO LINEAR MUTUALLY NORMAL HYDRAULIC DRIVES Russian patent published in 2003 - IPC

FIELD: machine engineering, namely hydraulic drives of adaptive robots with control servosystems. SUBSTANCE: hydraulic resolver is arranged on all three axes of gyroscope of adaptive robot and it is in the form of pair of angular hydraulic throttles being speed pickups and having hydraulic resistances whose values change proportionally from minimum one corresponding to cos= 1 until infinity corresponding to sin=0 and vice versa in each quarter of one revolution of gyroscope axis. Pair of hydraulic throttles of each hydraulic resolver is combined of different hydraulic pickups connected with mutually normal linear hydraulic drives. Axis of hydraulic resolver as third axis of Decart space is turned to projection plane of two stroke directions of said linear hydraulic drives. Values of hydraulic resistances of pair of hydraulic throttles of one hydraulic resolver are phase shifted by quarter of its axis revolution. Pair of hydraulic throttles is provided with one slide valve with casing. Slide valve has two mutually parallel rectangular openings; in its casing there are two through mutually normal round openings of the same diameter. Slide valve is arranged in casing with possibility of simultaneously closing one round opening according to sine law from 0 to 1 and other round opening according to cosine law from 1 to 0 and vice versa. EFFECT: possibility for automatically stabilizing speed of feeding working tool simultaneously by means of two or three linear hydraulic drive units. 3 dwg
