JOINT UNIT Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: joint unit has flanges with spherical recesses, insert arranged between flanges and equipped with spherical surfaces having different centers, and tightening member. Insert has three annular rings, i.e., middle and two outer rings interconnected through elastic deformation member providing deformation of insert under the action of axial force. Annular rings and elastic deformation member are equipped with longitudinal slots. Such construction allows precision requirements in manufacture of contacting spherical surfaces of joint unit to be reduced and occurrence of gaps between them being eliminated. Joint unit is preferably used in production of large-sized parts. EFFECT: simplified construction and enhanced reliability in operation. 3 dwg
