Patent number: 5447376Abstract: A self contained, "package", bearing system, has relatively rotating and sliding, precisely formed, truncated spherical, journal and bearing surfaces with a high hardness and with a low surface roughness, that operate on a thin hydrodynamic film of pressurized lubricant, when the bearing system is operated under any combination of axial and radial loads. It optionally contains either a supply of dry lubricant, or normally a capillary supported, self-contained reserve of fluid lubricant, and a system of "internally discharging" throwers, for keeping the fluid lubricant within the system, to promote a long operating life.Lubricant re-circulation channels at the ends of the bearing and the inherently lower rates of flow of lubricant from the ends of truncated spherical bearings facilitates achieving long operating life. Grooves and recesses are optionally included in the bearing surfaces for enhancing the axial load capacity.Type: GrantFiled: December 13, 1993Date of Patent: September 5, 1995Inventors: Eldon R. Cunningham, deceased, Shirley J. Cunningham, personal representative

Patent number: 5439203Abstract: The vibration-damping bushing is provided having an outer cylinder and an inner cylinder which are coaxially arranged with each other. A ring-shaped insert which is made of a resin material having good slidability is inserted between the outer cylinder and the inner cylinder so that the inner peripheral surface of the insert is closely disposed to the outer peripheral surface of the inner cylinder. A pair of ring-shaped vibration-damping rubber members are press-fitted between the outer cylinder and the inner cylinder on both sides of the ring-shaped insert with metallic sleeves joined to the inner and outer peripheral surfaces of said ring-shaped vibration-damping rubber members, respectively. The inside axial end of the inner peripheral surface of each vibration-damping rubber member is spaced apart from each axial end surface of the insert by a predetermined distance.Type: GrantFiled: October 26, 1992Date of Patent: August 8, 1995Assignee: Toyoda Gosei Co., Ltd.Inventor: Katsuya Hadano

Patent number: 5364191Abstract: A guiding ring (4) having a spherical inside surface is supported inside an annular rubber cushion (3) which in turn is supported inside a metal case (1). A body (2) having a spherical outer surface cooperates with the inner surface of the ring to permit rotational movement. Bellows (5) attached to axial abutments (6,7) of the case protect the joint from abrasive elements. The case is preferably in two parts which are press fit together, the rubber cushion being fixed inside one of the parts.Type: GrantFiled: March 9, 1993Date of Patent: November 15, 1994Assignee: Firma Carl FreudenbergInventor: Walter Gruber

Patent number: 5342128Abstract: An annular body (2) having a spherical outside surface is fixed coaxially on an annular rubber cushion (3) which in turn is fixed coaxially on a mounting rod (10). A guiding ring (4) is supported inside a case (1) and has a spherical inside surface which cooperates with the spherical outside surface of the annular body to permit rotational movement. The case has axial abutments (6,7) which limit rotational movement and serve as fixing points for bellows which protect the joint.Type: GrantFiled: March 9, 1993Date of Patent: August 30, 1994Assignee: Firma Carl FreudenbergInventor: Walter Gruber

Patent number: 5293784Abstract: The invention relates to a drive device for a vehicle rearview mirror, the positioning of which is achieved by means of a worm gear mounted by means of a coupling part in a single bearing, which is provided with an annular collar that engages in an upper annular slot of the coupling part. The intention is to improve the retaining force of the bearing.Type: GrantFiled: September 3, 1992Date of Patent: March 15, 1994Assignee: Gebruder Buhler Nachfolger GmbHInventors: Richard Guttenberger, Werner Seichter

Patent number: 5110221Abstract: A track-roller bearing assembly is disclosed which includes a fixed inner ball race member having an outwardly facing arcuate peripheral bearing surface; an annular body of self-lubricating bearing material affixed to the outwardly bearing surface of said inner race; and a coaxial outer race which is rotatable about an axis of the inner race and anguarly displaceable relative to the axis of the inner race so as to accommodate track deflections or irregularities. The track-roller further includes a resilient element disposed between respective ends of the inner and outer races so as to bias the races back into axial alignment after they have been angularly displaced relative to each other.Type: GrantFiled: December 16, 1988Date of Patent: May 5, 1992Assignee: Kamatics CorporationInventors: Glennwood H. Narkon, Stanley S. Orkin

Patent number: 5085520Abstract: A nose cone bearing arrangement for securing an axle box to a frame cross-tube of an off-road machine is provided. The axle box has an internal cylindrical bearing cavity therein. A metal double truncated spherical bearing surface is formed on and encompasses a truck frame cross-tube. A toroidal oil impregnated plastic bearing member having an external cylindrical surface is received within and conforms to the axle box internal bearing cavity. The plastic bearing has an internal concave bearing surface that engages the cross-tube spherical bearing surface.Type: GrantFiled: December 10, 1990Date of Patent: February 4, 1992Assignee: Terex CorporationInventor: Steven J. Fujan

Patent number: 5073038Abstract: A ball and socket bearing having a spherical ball member positioned within a non-metallic, molded bearing material which is in turn molded within a socket formed in a socket member. The socket provides openings on either side of the equator of the ball member having a radius less than the radius of the equator of the ball member so that a metal-to-metal interference prevents lateral separation of the members even in the event of bearing material failure. Further, the bearing material is relatively thin, at least between the ball member and socket adjacent to the lateral opening, so that the bearing material can support high lateral loads.Type: GrantFiled: July 12, 1990Date of Patent: December 17, 1991Assignee: Tuthill CorporationInventor: Timothy B. O'Connell
