Abstract:
A threaded joint for steel pipe formed on a pin and a box having a contact surface including threaded parts and a non-threaded metal contact part and capable of stably assuring a galling resistance and an airtightness without applying compound grease threreto, wherein a solid lubricating film formed with lubricating powder (e.g., molybdenum disulfide) and organic or inorganic binder is formed on the contact surface of at least one of the pin and the box, the ratio of area occupied by the secondary particles of 15 to 60 µm in equi-area equivalent diameter of the lubricating powder in the cross section of the solid lubricating film in thickness direction is 5 to 90%, and fiber-like filler (e.g., inorganic substance whisker) in addition to the lubricating powder is mixed into the solid lubricating film at the mass ratio of the fiber-like filler to the binder of 0.01 to 0.5, whereby, particulary, the galling resistance at high temperatures can be improved.
Abstract:
The retainer (20) of the present invention is made of a composite material having a body made from a polymer, a layer of solid lubricant formed over the body by chemically coating the body with a porous layer of solid lubricant and impregnating the solid lubricant with another lubricant using conventional methods such as vacuum impregnation. The retainer (20) is placed between an outer raceway (32) and an inner raceway (34) to form a self-lubricating bearing (30). The bearing (30) made in this manner has high lubrication tolerance (i.e. it performs well in the absence of external lubrication). Because of its high lubrication tolerance, the bearing is suitable for use in various applications such as dental/medical hand pieces that are periodically sterilized and other applications which occasionally experience periods of lubrication starvation.

A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, and acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft copolymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed. This process includes applying the lubricant composition to at least one of the surfaces. The lubricant composition in this instance comprises a superabsorbant polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.
