Patent number: 5971617Abstract: A self-lubricating bearing is fabricated as a laminate of a metallic substrate and a series of raised structures formed integrally therewith and extending orthogonally therefrom. A fluoropolymer sliding or bearing layer is superposed with the substrate, with the raised structures embedded therein. The raised structures serve to hold the bearing layer in place to help prevent it from sliding along the surface of substrate during bearing operation. This anchorage to the substrate enables a relatively thick bearing layer to be utilized to relatively reduce tendency to creep. Alternatively, the structures provide a bearing having a relatively thin load bearing layer with a relatively constant friction coefficient over its life, with the structures acting as thermal and electrical bridges for relatively high heat and electrical conductivity between the substrate and a supported article such as a rotating shaft. The structures also may be in direct contact with the supported article to help prevent bedding-in.Type: GrantFiled: July 24, 1997Date of Patent: October 26, 1999Assignee: Norton Pampus GmbHInventors: Peter Woelki, Dominique Petit, Friedrich Harig

The inner race is swaged to form the inclined axial bearing surfaces on the inner race after the races are assembled. A self-lubricating material is bonded to the inner race, including the axial bearing inclined surfaces thereof, after the inner and outer races are assembled and the axial bearing surfaces are formed.Type: GrantFiled: December 10, 1993Date of Patent: March 14, 1995Assignee: Kamatics CorporationInventor: Glenwood H. Narkon

Patent number: 5388915Abstract: A bearing bush for supporting the end of a shaft in a wall has a bush body with a through bore and a collar which projects radially at one end of the bush body and bears against the wall when the bearing bush is fitted into a bore in the wall. The length of the bush body is greater than the thickness of the wall. The inside surface of the bore of the bush body has a peripherally extending radial recess whose spacing from the collar is equal to the thickness of the wall. When the bush is installed in the bore in the wall the bush body can be compressed in the axial direction, undergoing plastic deformation, such that the bush body is upset to form on the side of the wall opposite the collar a radially projecting bulge portion which with the collar positively lockingly and immovably connects the bearing bush to the wall.Type: GrantFiled: May 6, 1993Date of Patent: February 14, 1995Assignee: Bavaria Cargo Technologie GmbHInventor: Thomas Huber

Patent number: 5319851Abstract: A method for manufacturing a bearing for a wiper arm structure includes the steps of: a) forming the bearing by sintering so that the outer peripheral surface of the bearing includes rough sintered surfaces of protruding ridges and recessed portion; b) sizing only the sintered surfaces of the protruding ridges without processing the recessing portions to smooth only outer peripheral surfaces of the protruding ridges so that the outer peripheral surfaces define a circular cross-section for the bearing, the sintered surfaces of the recessed portions remaining in a rough sintered condition relative to the outer peripheral surfaces of the protruding ridges which are sizing-processed; and c) forming a resin material on the outer peripheral surface of the bearing by insert molding.Type: GrantFiled: January 12, 1993Date of Patent: June 14, 1994Assignee: Mitsuba Electric Manufacturing Co., Ltd.Inventors: Ryu Ikezawa, Hironobu Kishi

Patent number: 5279018Abstract: A rotary bearing is disclosed for pivotably connecting a journal to a similar cylindrical saddle formed in a chassis member. The rotary bearing is provided with an annular sleeve having inner surface sides to freely rotatably cooperate with the journal. The annular sleeve outer surface has affixed to it an arcuate flange extending radially outward and about a limited portion of the sleeve periphery. The flange includes a relatively thin web section and a thicker head portion spaced radially outward therefrom to enable the flange to interconnect with the arcuate slot formed in a semi-cylindrical saddle surface. The rotary bearing can be quickly installed and removed without the use of fasteners or installation tools and is particularly suitably adapted for use in mounting an upright vacuum motor/fan assembly to the cleaner head chassis.Type: GrantFiled: January 10, 1992Date of Patent: January 18, 1994Assignee: Ryobi Motor Products Corp.Inventor: William K. Glenn, III

Patent number: 5263778Abstract: The elastic sliding bearing for chassis parts in motor vehicles has a rigid inner bushing, an outer bushing, and an elastomeric body surrounding them. The inner bushing and the outer bushing are provided at both ends with axial bearing surfaces on radially extending flange projections (8, 9), and a seal surrounding the flange projections (8) on the outer bushing (2) is provided. The seal acts against the axially outer flange surface of the outer bushing (2) with at least one sealing lip. A plastic layer (5) possessing good sliding properties, whose outer contact surface with the outer bushing has lubricant pockets (6) for receiving a grease filling, is provided on the outer jacket of the inner bushing (1).Type: GrantFiled: October 10, 1991Date of Patent: November 23, 1993Assignee: Lemforder Metalwaren AGInventors: Ernst-Gunter Jordens, Helmut Kammel

Patent number: 5232342Abstract: A high pressure multi-stage centrifugal pump with an axially split casing (10) and a number of impellers (14) carried by a drive shaft (12) has inter-stage bushings (24) and rings (22) for sealing each side of each impeller. Each bushing (24) or ring (22) is conventionally prevented from rotating by a radial pin protruding from the lower half of the casing (10) into an axial slot in the periphery of the bushing or ring. The pin is necessarily small and is liable to shear, difficult to engage in the slot and, in cases where the bushing (24) or ring (22) is diametrically split, does not allow rotation of the lower half for its removal without lifting the shaft (12). To avoid all these disadvantages, without introducing any risk of leakage, a tangential pin (32) is fitted in a blind hole (34) in the casing (10) so that its exposed end (37) is flush with the joint face (28) of the casing and abuts against a shoulder ( 44) formed by a recess (38) in the periphery of the bushing (24) or ring (22).Type: GrantFiled: November 13, 1992Date of Patent: August 3, 1993Assignee: David Brown Engineering LimitedInventor: Peter Thompson
