Mechanical interference structure may also be provided to act on the trunion pins to prevent their rotation and thus removal once installed.Type: ApplicationFiled: April 17, 2001Publication date: November 7, 2002Inventor: Richard Kremer Riefe

Patent number: 6428418Abstract: A universal joint yoke with two parallel yoke legs, which have a partial area for a bearing eye hole, is presented, in which the inner sides of the yoke legs facing one another have areas of thickened material in the unfinished state in the areas of the bearing eye holes. Due to this feature according to the present invention, it is possible to obtain a sufficient mounting overlap for the needle bearings arranged in the bearing eye holes, on the one hand, and a maximum possible passage is obtained at the same time for a through hole necessary for the connection to connection profiles in the universal joint yoke.Type: GrantFiled: October 30, 2000Date of Patent: August 6, 2002Assignee: Nacam Deutschland GMBGInventors: Herbert Appelt, Sonja Winsel

Patent number: 6390927Abstract: An improved universal joint device for socket wrenches. The improved device is constructed with non-slip spring retaining surfaces on the handle and socket portions of the device for receiving the ends of a coil spring which can maintain the universal joint in alignment during both tension and compression. The device is otherwise free of grooves or apertures for mounting the spring to the handle and socket portions.Type: GrantFiled: March 29, 2000Date of Patent: May 21, 2002Assignee: Cleveland Tool CorporationInventor: Orison Cleveland, III

Patent number: 6375577Abstract: A coupler for connecting a drive shaft to a driven member and accommodating a substantial misalignment between the drive shaft and the driven member, while minimizing audible noise and vibration. The coupling includes a hollow core nest element having a plurality of slots formed in one end, two substantially identical elongate body elements, and a plurality of spring elements. Each elongate body element has two ends, a first end being adapted to couple with either the drive shaft or the driven member, and a second end that includes a plurality of posts that engage the slots of the hollow core nest.Type: GrantFiled: October 27, 1999Date of Patent: April 23, 2002Assignee: Abbott LaboratoriesInventors: Thomas L. Smith, Peter A. Holst

Patent number: 6318923Abstract: A coupling comprises blade flexures that connect two end members through which control rods extend to cross members that are attached near the mid-points of the blade flexures, providing stable-linear load reaction means for use as end pivots for linkages where stick-slip motion is undesirable. The blade flexures are housed in a rigid cage comprising four separators that are attached to end members, and the flexures are attached to the end members by the separators.Type: GrantFiled: March 14, 2000Date of Patent: November 20, 2001Assignee: Honeywell International Inc.Inventor: Toren S.

Patent number: 6293167Abstract: A universal joint is provided having a generally cup-shaped yolk. The yolk includes a base and a generally cylindrical wall projecting therefrom. The wall partially defines a cavity in the yolk. A shaft extends a longitudinal axis and has a ball on the first end thereof. The ball is receivable within the cavity and the yolk. Mounting structure is provided for pivotably supporting the ball in the cavity of the yolk.Type: GrantFiled: January 11, 2000Date of Patent: September 25, 2001Assignee: IMO Industries, Inc.Inventors: Frederick E. Latz, Ronald C. Singleterry, Andrew K. Stiteler, Terry W. Craftchick

Patent number: 6244966Abstract: A torsionally-rigid compensating coupling between first and second shaft ends has a ball bearing element positioned on the first shaft end and a ball socket element with grooves positioned on the second shaft end, with the ball bearing element including a ball bearing and a drive pin extending through the ball bearing. Pin ends of the drive pin extend out of the ball bearing into the grooves of the ball socket element. The grooves and ball socket of the ball socket element, in a longitudinal direction of the second shaft end, open out into a cylindrical recess that has a guide chamfer. The ball bearing element includes an elastic-force creating member and stops, with the elastic-force creating member driving the drive pin against the stops to fix the drive pin in its working position by elastic force, the drive pin being moveable against the elastic force in a longitudinal direction of the second shaft end.Type: GrantFiled: September 9, 1999Date of Patent: June 12, 2001Assignee: Preh-Werke GmbH & Co. KGInventors: Thomas Ofenhitzer, Oliver Zegula

Patent number: 6200224Abstract: This slidable constant velocity universal joint comprises an outer joint member 1, and a tripod member 4 having a plurality of axially extending leg shafts 5 and outer rings 3 which are rotatably fitted on the leg shafts 5 and whose outer peripheries 3b are spherical. The tripod member 4 is received inside the outer joint member 1, and the outer rings 3 of the tripod member 4 are fitted in track grooves 2 in the outer joint member 1 so that they are slidable axially of the outer joint member. A sliding contact region S where relative sliding between the outer ring 3 and the leg shaft 5 in the leg shaft direction occurs is defined between the outer ring 3 and the leg shaft 5, and the outer ring 3 is allowed to swing around the axis of the leg shaft 5. The center of curvature O of the outer periphery of the outer ring 3 coincides with the sliding contact region S, thereby preventing the outer ring 3 from exhibiting unstable behavior before and after specific phases (0°, 180°).Type: GrantFiled: June 30, 1999Date of Patent: March 13, 2001Assignee: NTN CorporationInventors: Tatsurou Sugiyama, Shigeyoshi Ishiguro, Hisaaki Kura
