Patent number: 5184920Abstract: A connection element for a three-dimensional framework includes a bolt (6, 7, 8, 9) which by means of a sleeve insert (3) can be fastened rotatably to one end of a rod (11), as well as a sleeve (12) into the axial through-bore of which the bolt is partly inserted, to transmit, sliding axially, a rotary movement of the sleeve (12) to the bolt. The through-bore is only in the front part of the sleeve (12) so that it can transmit a rotary movement of the sleeve (12) to the bolt. At the rear part of the sleeve (12) the through-bore has a circumference which is larger than the circumference of the form-locking front part of the through-bore. The bolt is urged out of the sleeve (12) by a spring (13). The front end part (9) of the connection element can be fastened to a junction part (10) of the three-dimensional framework.Type: GrantFiled: September 23, 1991Date of Patent: February 9, 1993Assignee: Syma Intercontinental AGInventor: Marcel Strassle

Patent number: 5181792Abstract: A retainer embodying the concepts of the present invention is adapted for releasably securing a splined radially innermost rotatable member to a splined radially outermost rotatable member. The retainer so secures the rotatable members in order to preclude relative axial displacement therebetween. The retainer has a body portion. A first stop surface is presented from the body portion to engage one of the rotatable members and thereby preclude relative axial movement between the body portion and that rotatable member in one axial and directional frame of reference. A first dog extends outwardly from the body portion to engage the same rotatable member engaged by the first stop surface and thereby preclude relative axial movement between the body portion and that rotatable member in the opposite axial and directional frame of reference.Type: GrantFiled: March 13, 1992Date of Patent: January 26, 1993Assignee: General Motors CorporationInventor: Edwin T.

Patent number: 5180249Abstract: A thermally stressed rotary connection of two coaxially aligned shafts includes two metallic coupling sleeves which are connected with the shafts by way of elastic intermediate layers. The two metallic sleeves engage one another. A ceramic centering sleeve is provided radially around the outside of the coupling sleeves and is shrunk onto the two shafts. The arrangement has the advantage of an effective connectability of different shafts such as ceramic or metal, in which case the two shafts may be connected with one another during the mounting. This allows undivided housings to be used.Type: GrantFiled: April 11, 1991Date of Patent: January 19, 1993Assignee: MTU Motoren-und Turbinen-Union Munchen GmbHInventors: Hagen Hanser, Hubert Grieb

Patent number: 5174677Abstract: Main rotor pitch control rod assemblies on helicopters constitute means for ranslating an aviator's control impulses in the cockpit to the main rotor blades. Pitch control rod assemblies typically include means for locking the assembly into a predetermined attitude setting. The setting may be held by locking nuts. This invention provides a passive locking means using spring tension to maintain the desired setting if the locking nuts loosen due to stress loads or improper torquing during maintenance. The invention also provides passive means for maintaining expansive stress within the control rod to prevent distortion of the assembly under compressive loads.Type: GrantFiled: August 30, 1991Date of Patent: December 29, 1992Assignee: The United States of America as represented by the Department of the ArmyInventors: Leonard J.
