    摘要: The present invention relates to a copper base alloy suitable for use in bearing structures. The copper base alloy consists of from about 15 wt % to about 90 wt %, preferably from about 50 wt % to about 60 wt %, silver and the balance essentially copper. The copper base alloy is advantageously applied to a surface of a component used in the bearing structure such as a surface of a bushing.

    摘要: An aluminum thrust washer that has a wrought aluminum matrix that includes from 2 to 20 weight percent silicon, 0.1 to 4 weight percent of copper, with the remainder pure aluminum. The aluminum thrust washer is formed of a mono-metal structure without a backing layer. The wrought aluminum matrix has mechanical properties such that the aluminum matrix wears away, leaving silicon particles exposed at a thrust face of the washer, such that the density of silicon particles is continually increasing as the thrust washer is utilized.

    摘要: A rolling cutter drill bit comprises a body and three legs, each leg having a cantilevered bearing spindle, a rolling cutter rotatably mounted on the bearing spindle, lubricant delivering means within the bearing spindle, and a floating thrust bearing element configured to carry onward thrust loads from the rolling cutter onto the bearing spindle. Each floating thrust bearing element is formed of a wrought alloy material consisting primarily of chromium carbide and cobalt and having a yield strength of less than 120,000 psi and a ductility of at least 4%, both at room temperature.

    摘要: A self-acting air bearing wherein an abrasion-generated substance is generated by rotation of a shaft and a bearing and is used as a lubricant. As a result, a motor of low cost and stable rotation in which it is not necessary to insert special lubricant into the shaft or the bearing previously can be achieved. Moreover, in a polygon motor having such a lubrication structure, since polluting of a writing system is not feared, reliability for a long time period can be obtained.

    摘要: A cam follower apparatus includes at least a roller and a supporting shaft for supporting the roller freely rotatably. Unevenness is formed equally on the surface of at least one of the roller and supporting shaft by corrosion by manganese phosphate salt and the manganese phosphate salt film is formed on the corroded surface. Good-quality oil film can be formed stably without interruption thereof under even a strict working condition with a small amount of lubricant due to the unevenness formed on the film. Therefore, direct contact between metals is prevented, thereby improving lubricity.

    摘要: The present invention is intended to provide a pressed retainer which can meet requirements for operation at high temperature and high speed, can sufficiently retain lubricant, does not allow ceramic balls, if used, to cut away track surfaces and is superior in wear resistance, and also intended to provide a ball bearing comprising the pressed retainer.In order to solve problems, in the pressed retainer, wherein two ring-shaped retainer plates, having ball retaining portions and flat portions at predetermined intervals in the circumferential direction thereof, are combined to face with each other so as to form pockets for accommodating balls, a first spherical concave portion and a second spherical concave portion having a curvature radius smaller than that of the first spherical concave portion are formed at the ball retaining portions, and a nitrided layer is formed on the surfaces of the ring-shaped retainer plates. The ball bearing of the present invention uses the pressed retainer and ceramic balls.
