Dст≥Dш+δ,
Dn≤Dш-2δ,
где Dст - внутренний диаметр стакана;
Dп - наружный диаметр пяты;
Dш - диаметр шара;
Dш≥4δ,
δ- величина эксцентриситета ротора относительно статора,
а зазор между шаром и дном стакана равен максимально допустимому люфту в узле осевой опоры.A downhole hydraulic motor comprising turbine sections, a gerrotor screw mechanism with a stator fixed in the housing, and an eccentrically located rotor with a split torsion bar, characterized in that the gerotor mechanism in the upper part is equipped with a stop element in the form of a disk-shaped plate fixed relative to the stator with holes in the peripheral part and a glass in the center, periodically interacting by means of a ball placed in the glass, with a fifth, which is fixedly fixed with the upper part of the eccentric p otor, and the detachable connection of the torsion bar is located at its lower end, at the junction with the shaft of the turbine sections, and the inner diameter of the glass, the outer diameter of the heel and ball are related by the ratios
D article ≥D w + δ,
D n ≤D w -2δ,
where D article - the inner diameter of the glass;
D p - the outer diameter of the heel;
D W - the diameter of the ball;
D W ≥4δ,
δ is the magnitude of the eccentricity of the rotor relative to the stator,
and the gap between the ball and the bottom of the glass is equal to the maximum allowable play in the node of the axial support.
