  • Patent number: 7060199
    Abstract: The invention relates to a water-based biodegradable and non-toxic functional fluid for mechanical drives, preferably for use in steam engines. The object of providing such functional fluids for use in mechanical drives, particularly for the hydrodynamic lubrication of plain bearings, preferably for crankshafts of superheated steam engines, having customary bearing play which is not overly precise, is achieved. It should be capable of being used in closed power plant systems also at sump temperatures higher than 120° C., e.g. in the crankcase under a crank shaft, and should be water-based or water-dilutable. According to the invention, this is achieved by addition of a low percentage of polyaspartic acid to water or to water/glycol mixtures, preferably polyaspartic acid having a molar mass of from greater than 1 000 to 10 000 g/mol being used.

  • Publication number: 20040094743
    Abstract: The invention relates to a water-based biodegradable functional fluid for mechanical drives, preferably for use in steam engines. The aim of the invention is to create functional fluids for use in mechanical drives, particularly for hydrodynamically lubricating plain bearings, preferably for crankshafts of superheated steam engines having customary non-overly precise bearing play. The inventive fluids should be able to be used in closed power pack systems also in the existence of sump temperatures exceeding 120 ° C., e.g. in the lubricant pan located under a crank drive and be water-based or able to be diluted with water. According to the invention, this is achieved by a percentually low addition of polyaspartic acid to water or to water-glycol mixtures, whereby polyaspartic acid having a molar mass greater than 1,000 and up to 10,000 g/mol is preferably used.

  • Patent number: 6450594
    Abstract: A hinge assembly for a vehicle track, conveyor chain or the like has at least one bearing lacquer coated onto at least one of the mutually contacting surfaces of the pin or bushing and having a binder or carrier of the polyamide/polyimide type or of a molecular structure with alternating amide and imide monomers. A filler of molybdenum disulfide, molybdenum oxides and/or hydroxides and graphite is provided in the carrier or binder. Other lubrication is not required and the bearing lacquer has a long life.
