  • Publication number: 20090044409
    Abstract: Methods for manufacturing bearings and wear resistant surfaces usable in various downhole tools are described herein. A housing is provided. A laser configured for insertion into the housing, such as an inner diameter laser, is used to connect a fusible material to the inner surface of the housing or an insert disposed therein to form a hard facing layer on the inner surface. Simultaneously or independently, the laser can be used to connect the fusible material to the outer surface of a mandrel within the housing to form a second hard facing layer. The present methods thereby produce durable radial bearings having extended operational life, which can be produced within a bearing housing, or externally for transport and installation in existing bearing housings.

  • Publication number: 20090028477
    Abstract: Bearing arrangement for a creel for holding a wind-on bobbin for winding on an elongate textile strand, wherein the bearing arrangement has a bushing, which surrounds a pin, wherein alternatively either the bushing or the pin is non-rotatably connected to the creel, and wherein the pin and bushing can be rotated relative to one another, so the creel is pivotable. According to the invention, the bushing (15, 15A) is fixed by means of a press ring (16, 16A) positioned with a press fit on the bushing (15, 15A).

  • Publication number: 20090003740
    Abstract: The invention relates to a slide bearing material comprising a metallic supporting layer and a metallic lead-free porous carrier layer which is sintered on the supporting layer and used to receive a sliding layer material based on a polymer, said carrier layer consisting of a tin bronze with bismuth additives. The aim of the invention is to achieve a higher scoring resistance. To this end, the carrier layer consists of a sintering powder consisting of powder particles containing between 9.5 and 11 wt. % of tin and between 7 and 13 wt. % of bismuth and copper, and the powder particles have a bulbous shape deviating from the regular spherical shape but without edges and undercuts.

  • Publication number: 20080317393
    Abstract: A bushing assembly is disclosed and includes a bushing that can have an outer surface and an inner surface that can define an opening. The bushing can be configured to fit into a bore and receive a shaft through the opening. An engagement torque, T, between bushing and the shaft does not increase more than twenty-five percent as an interference fit between the bushing and the bore increases. The interference fit can be quantified by a reduction in outer radius, I, by at least 0.025 mm.

  • Publication number: 20080269880
    Abstract: Rotary hydrodynamic blood pumps have been used to treat over a thousand patients. The Jarvik 2000 has supported a patient for seven years and uses blood immersed bearings washed by high flow to avoid excessive thrombus formation. This permits the pump to be very simple and small. Nonetheless, the present Jarvik 2000 bearings and all other mechanical blood immersed bearings of the prior art have a supporting structure that predisposes to thrombus adjacent to the bearings. The present invention provides a bearing structure that eliminates this predilection site for thrombus formation, and may provide indefinite thrombus free operation. The rotor of the preferred embodiment includes a tapered hub fabricated of wear resistant material supported by three posts at each end of the rotor, upon which the rotor rotates. Blood washes the unobstructed spaces between the posts to prevent the accumulation of a torus of thrombus that could enlarge excessively.
