摘要:
The present invention describes a method for increasing the endurance of oil lubricated conical roller bearings, in which the guide surface is coated with a lubricating paint that is insoluble in oil. A coating of a molybdenum disulphide lubricating paint with a thickness of 3 to 8 .mu.m is preferred. The coated bearing also exhibits reduced friction and quieter running, even when the lubricating paint has been worn off.
摘要:
An improved lubricating oil composition comprising a major amount by weight of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount of an oxidized olefin polymer which has been reacted with an aliphatic amine or polyamine. Preferably, this reaction occurs in the presence of a formaldehyde-yielding reactant. This composition provides improved inhibition of sludge and varnish formation in use.
摘要:
Release and lubricating composition for avoiding seizure between molten glass and metal molds for forming glass articles, for minimizing wear between mold sections and for improving the pack of glassware, comprising, a dispersion of graphite in a polyphenylene sulfide, molds having such composition coated thereon, and a method of applying the composition to molten glass contacting surfaces comprising dispersing the composition containing graphite with the polyphenylene sulfide in the form of small particles in a carrier, applying the dispersed composition to the glass contacting surface and then curing the coating at an elevated temperature, including curing resulting from hot molds during glassware production.
摘要:
Dry lubricated members particularly adapted for use as cold side rubbing seals in the regenerator section of gas turbine engines, the members comprising a substrate with an initial working surface of an iron oxide matrix containing an interspersed mixture of graphite and a trapping material in the form of an inorganic compound such as salt or oxide. Subsequent to a breakin period the work surface and any mating surface therewith both acquire a substantially continuous film of high oriented iron hematite - Fe2O3.

摘要:
This invention relates to an organometallic reticulated antifriction composition comprising at least one solid epoxy resin containing terminal epoxy groups and a molecular weight in the range from about 2,000 to 4,000 having incorporated therein from about 5 to 60 percent by weight of lead and/or bismuth powder or powdered alloys containing lead and/or bismuth, said reticulation having been caused by heating the composition for a sufficient period of time and at a sufficient temperature to effect said reticulation. This invention also relates to metal bearings coated with said organo-metallic anti-friction compositions and their method of manufacture.
摘要:
A self-lubricating bearing comprising a molded composite material prepared by blending lubricating oil, polynorbornene type resin and/or expanded graphite, and a main bearing material comprising a self-lubricating and abrasive resistant synthetic resin. Metal powders may be added to the synthetic resin as the main bearing material. The inventive bearing can perform under heavy loads and have a long life time.
摘要:
A solid lubricant comprising a substantially amorphous carbon micro-sphere selected from carbon micro-beads and carbon micro-balloons having a particle size of 0.1 to 1,000.mu. and a specific gravity of the particle of 0.2 to 2.0, which has excellent low frictional coefficient and wearing resistance.
摘要:
A fire-resistant grease comprises a fire-resistant base oil and graphitic carbon or oleophilic graphite as a thickener. Suitable base oils include fire-resistant hydraulic fluids, particularly phosphorus acid esters or amides and more particularly trihydrocarbyl phosphates. The graphitic carbon may be of the type described in U.K. Pat. No. 1,252,582 (U.S. Pat. No. 3,532,625) and the oleophilic graphite as described in U.K. Pat. No. 1,168,784 (U.S. Pat. No. 3,384,583). The thickener contact may be 1-20% wt of the grease, preferably 2-10% wt, and the grease may contain conventional additives.
摘要:
An improved lubricating oil composition comprising a major amount by weight of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount by weight of at least one of certain specific polymers has been found to provide improved inhibition of sludge and varnish formation in use. The polymers useful in the present composition comprise(1) an olefin polymer, for example, an ethylene, propylene and 1,4-hexadiene terepolymer, with an dialkylaminoalkyl methacrylate grafted thereon;(2) an interpolymer prepared from a long chain n alkyl-methacrylate and a dialkylaminoalkylmethacrylate or a N (alkanone) acrylamide; or(3) mixtures thereof.
