Abstract:
The object of the invention is a traction sheave elevator and a rope that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands laid from metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating the rope. The lubricant comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.
Abstract:
The present invention relates to a lubricating composition for forging in the form of a powder or a compacted powder including: one or more dicarboxylic acid(s) chosen among adipic acid, phthalic acid, isophthalic acid, terephthalic acid, sebacic acid, succinic acid and suberic acid; and one or more base(s) chosen among sodium carbonate, sodium bicarbonate, potassium carbonate and potassium bicarbonate, the dicarboxylic acid(s)/base(s) molar ratio ranging between 0.8 and 1.2.
Abstract:
The present invention provides a grease composition capable of effectively preventing a rolling surface from having hydrogen brittleness-caused peeling, a grease-enclosed bearing in which the grease composition is enclosed, and a one-way clutch in which the grease composition is enclosed at a sliding portion. The grease composition contains a base grease consisting of a base oil and a thickener and an additive added to the base grease. The grease composition is capable of preventing hydrogen brittleness-caused peeling from occurring on a frictionally worn surface of a bearing portion containing an iron-based metal material or a newly generated surface consisting of the iron-based metal material exposed owing to wear. The additive contains at least one aluminum-based additive selected from among an aluminum powder and inorganic aluminum compounds. The mixing ratio of the aluminum-based additive to 100 parts by weight of the base grease is set to 0.05 to 10 parts by weight.
Abstract:
A water-based lubricant for plastic working of a metallic material is obtained by adding to a water-based medium: (A) a polymer and/or a salt thereof containing a carboxylic acid or a derivative thereof as a constituent monomer; (B) an oxoacid of tungsten, of silicon, or of phosphorus, or a condensate thereof, and/or a salt thereof; (C) a hydroxide of an alkali metal; and (D) a lubricating component (D), and the solid content weight ratio (A)/[(A)+(B)+(C)+(D)] is 0.05 to 0.4.
Abstract:
Embodiments of the present disclosure provide for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles.
Abstract:
Composite particles and a method of forming composite particles are described. The composite particles comprise at least one inorganic nanoparticle covalently bound to at least one inorganic microparticle with a linking compound. Lubricant compositions and sprayable dispersion compositions comprising composite particles are also described.
Abstract:
A method of manufacturing an overbased calcium sulfonate grease comprising a reduced amount of overbased calcium sulfonate, water and at least one non-aqueous converting agent, where at least a portion of the non-aqueous converting agent is added after one or more delay periods relative to the addition of the water. A delay period may involve the period of time it takes to adjust the temperature of the mixture, a period of time during which the mixture is held at a temperature or within a range of temperatures, and multiples and any combination thereof. These calcium sulfonate greases have improved thickener yield and high dropping points compared to greases of substantially similar composition made without a delay between the additions of water and a non-aqueous converting agent, particularly when a poor quality overbased calcium sulfonate is used.
