GAPS FREE HINGE OF EQUAL ANGULAR SPEEDS Russian patent published in 2010 - IPC F16D3/224 F16D3/16 

FIELD: machine building.

SUBSTANCE: invention refers to hinge of equal angular speeds. The hinge consists of an external part with external paths distributed along circumference, of an internal part with internal paths distributed along circumference and of a circular-shape ball separator. Also pairs of paths expand in axial direction when the hinge is partially elongated. Balls transmitting torque are inserted in the said pairs of paths. The separator rests between the external part of the hinge and external part of the hinge and has openings for the said balls distributed along circumference. The internal part of the hinge has an axial gap relative to the ball separator. Notably, there is facilitated a device, particularly a journal, to ensure a spring support of internal part of the hinge relative to the external part of the hinge. The journal is installed coaxially to the external part of the hinge and is either movable relative to it, or is rigidly inserted into it. Additionally, an interval of contact area of mutual support of the internal part of the hinge and external part of the hinge from the centre of the hinge is less or equal to half of external diametre of the ball separator, thus ensuring maintaining moment of leading at an insignificant value.

EFFECT: design of gaps free hinge with insignificant moment of leading.
