CONNECTION OF DEVICE OF BALL HINGE WITH ANGULAR TRANSMISSION PLUG TYPE, CONTROL SYSTEM OF STRAIGHTENER BLADE WITH ADJUSTABLE BLADE SETTING ANGLE, WHICH CONTAINS SUCH CONNECTION, AND AIRCRAFT ENGINE EQUIPPED WITH SUCH SYSTEM Russian patent published in 2012 - IPC F16C11/04 F01D17/14 F04D29/56 

FIELD: machine building.

SUBSTANCE: connection of angular transmission fork and device of ball hinge type includes unthreaded connection bar, the first sleeve and the second sleeve. Angular transmission fork includes the first and the second eyes with holes made along the connection axis. Device of ball hinge type includes inner ring and outer ring installed with possibility of rotation on inner ring. Bar comprises a head including a flat face. The first eye of fork includes a cut on outer surface of the first eye so that flat face of bar head is borne against it in order to prevent bar rotation. The first sleeve is located in hole of the first eye; at that, its body is inserted in hole of the first eye in order to prevent rotation of the first sleeve relative to angular transmission fork. The second sleeve is located in hole of the second eye. Each of sleeves includes a rim with end surface which is borne against inner ring and with opposite surface which is borne against the first eye and the second eye respectively. Each of the first and the second sleeves includes eyes projecting from end surface of the rim and inserted in projection of inner ring in order to prevent its rotation relative to sleeves. The first end of bar is located closer to bar head than the second one is; at that, the other bar end is inserted in inner diameter of the second sleeve in order to prevent its rotation.

EFFECT: invention allows reducing overall dimensions of connection.
