Publication number: 20130084186Abstract: The centrifugal force bearing includes a plurality of tapered metal shims such that the thicker end of each tapered metal shim near the inner portion of bearing. The bearing can include a plurality of tapered elastomeric members that are consequently tapered so that the inner portions are narrower than the outer portions. The tapered metal shims can increase the axial stiffness in the direction of the centrifugal force, thereby reducing the axial deflection under loading, as compared to non-tapered shims. Further, reducing axial deflection reduces clearance issues that may arise when the rotor blade is allowed to axial deflect significant distances. As such, the tapered metal shims can increase the capacity of the bearing. Tapering the metal shims can decrease the compression induced shear strain near the outer portions of the elastomeric member, where loads are typically higher.Type: ApplicationFiled: August 29, 2012Publication date: April 4, 2013Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Daniel P.

Patent number: 7870913Abstract: Various aspects of the present invention relate to bearing assemblies configured to accommodate non-uniform loading and misalignment with an adjacent bearing assembly. In one aspect of the present invention, a bearing assembly is disclosed. The bearing assembly comprises a compliance ring including a plurality of beams. Each of the beams is circumferentially spaced apart from each other. The bearing assembly further comprises a plurality of bearing elements, with each of the bearing elements positioned adjacent to a corresponding beam of the plurality of beams. Each of the bearing elements deforms one of the corresponding beams when loaded. An additional aspect of the present invention is directed to a bearing assembly in which bearing elements thereof may be mounted to a support element without using a brazing process.Type: GrantFiled: July 18, 2007Date of Patent: January 18, 2011Assignee: US Synthetic CorporationInventors: Timothy N. Sexton, Craig H. Cooley

Publication number: 20100260448Abstract: Disclosed is a radially movable floating bearing for a shaft of a gear of a steering system, comprising a bushing or an inner ring or a rolling bearing, which is supported in a seat of a frame or housing of the gear. The inner ring or the bushing or the rolling bearing is held by at least one support element made of material having elastomeric properties which is inserted into a gap between the seat and the inner ring, the support element being designed as a pivot bearing. In order to provide a radially movable floating bearing for a steering system gear shaft, which is low-noise, easy to pivot and highly resilient, the pivot bearing cooperates with a damping stop disposed tangentially at a distance thereto, the stop being disposed at a radial distance from the inner ring or the seat.Type: ApplicationFiled: April 26, 2010Publication date: October 14, 2010Applicant: ZF Lenksysteme GmbHInventors: Jens-Uwe Hafermalz, Dennis Fuechsel

Patent number: 7784830Abstract: A telescoping steering column assembly has an inner jacket and an outer jacket telescopically engaged with a sleeve between the inner and outer jackets. The sleeve has internal and external ribs which run parallel to a longitudinal axis of the sleeve, the internal ribs contacting an outer surface of the inner jacket, and the external ribs contacting an inner surface of the outer jacket. The internal and external ribs are circumferentially offset to allow the wall of the sleeve to flex relative to the opposing surfaces of the jackets, resulting in smooth telescoping action of the assembly without lash. In addition, the system provides a constant collapsing force and provides guidance for a controlled collapse of either a telescoping or non-telescoping column assembly in a vehicle crash impact.Type: GrantFiled: October 23, 2003Date of Patent: August 31, 2010Assignee: Chrysler Group LLCInventor: Peter J. Ulintz

Publication number: 20100192893Abstract: A bearing device includes a plurality of pairs of bearing parts for supporting shafts to each of which a plurality valves are attached and connecting parts for connecting the bearing parts. Each connecting part is elastically deformable and includes a bent portion in a bent shape to absorb the force that will act in at least one of an axial direction and a radial direction of the shafts when the shafts are rotated.Type: ApplicationFiled: December 17, 2009Publication date: August 5, 2010Applicant: AISAN KOGYO KABUSHIKI KAISHAInventors: Shinji Iwata, Naotaka Yoshikawa

Patent number: 7766550Abstract: An exemplary spring for positioning a turbocharger bearing in a housing includes a free standing inner diameter, a free standing outer diameter and a substantially sinusoidal shape to provide an inward radial bias and to provide an outward radial bias wherein the spring balances the inward radial bias with the outward radial bias to thereby position a turbocharger bearing in a housing. Various exemplary springs, bearings, housings, assemblies, etc., are also disclosed.Type: GrantFiled: August 6, 2009Date of Patent: August 3, 2010Assignee: Honeywell International Inc.Inventor: Gerald D.

Publication number: 20100160138Abstract: A mounting means is provided for mounting a device comprising at least one mounting shield, a pivot bearing arranged in the mounting shield and a rotor mounted perpendicularly in the pivot bearing, an axis of rotation of the rotor being oriented substantially perpendicularly when the device is mounted on the mounting means, and the mounting means having resilient properties. In one embodiment, the resilient properties of the mounting means are direction-dependent, in particular orthotropic. As a consequence of the direction-dependent resilient properties of the mounting means, oscillations excited by a rotary movement of the rotor strike a mounting, the pivot point of which does not coincide with the axis of rotation of the rotor, but is set apart therefrom. This makes it much more difficult to excite the mounting means to form unstable oscillations, so that such oscillations are effectively damped.Type: ApplicationFiled: December 15, 2009Publication date: June 24, 2010Applicant: THERMO ELECTRON LED GMBHInventor: Sebastian Henne

At least one compliant member may be positioned between at least one selected bearing element of the at least one bearing element mounted to the rotor and the at least one bearing element mounted to the stator. Mechanical systems including such a bearing apparatus are disclosed, such as, for example, a motor for use in subterranean drilling. A method of assembling a bearing apparatus is disclosed. More specifically, a rotor and a stator each including at least one bearing element may be provided and a compressive force may be applied to the rotor and the stator to compress the bearing surfaces of the rotor and the stator against one another.
