FIELD: oil producing industry: testing facilities.
SUBSTANCE: proposed stand contains one fixed clamping device and at least two self-aligning clamping devices, all coupled with mounting bases. Self-aligning devices are made for mounting under weight of downhole hydraulic motor at angle equal to angle of deflection of moving section relative to spindle section of downhole hydraulic motor in deflector assembly. Self-aligning devices consist of three plates, namely main, intermediate and turnable ones. Main plate is coupled with mounting base of stand, being provided with at least three longitudinal slots on its surface. At least three bushings are installed in intermediate plate. Bushings are pressed on by flat springs by means of which intermediate plate is lifted over main plate for displacement on ball bearings along slots in main plane along main plate. Turnable plate is installed on axle secured in intermediate plate, being lifted over intermediate plate by means of spring installed on axle for free turning relative to intermediate plate.
EFFECT: enlarged testing capabilities of stand for downhole hydraulic motors including tests in deflector assembly.
