Abstract
The hinge clutch of drill string has hollow body with profile surface in its lower section, the lower and the upper bearings installed in the body, those form the inner spherical surface, support toe with spherical section being in contact with the spherical surface formed by the bearings and profile section that is kinematically connected to the profile surface of the body, and tightening rings for sealing the body with respect to the upper bearing and the last one with respect to the spherical section of the support toe. The profile surface on the body is arranged in the lower section of its opening. The last one, similarly to the surface of the profile section of the support toe, is formed by three flat spots, two of those are parallel to the plane of curving, the third flat spot on the surface of the profile section of the support toe is normal to the plane of curving. The third flat spot on the profile surface in the opening of the body is arranged with wedge reboring along the axis of the clutch, there wedge is installed with gap with respect to the third flat spot on the profile section of the support toe, this determines the angle of curving of the clutch.
