The manufacturing index values can then be used to construct a manufacturability window for each lubricant product. The manufacturability windows for each lubricant product can then be analyzed to determine regions of overlap, if any, where a proposed blending component can be used with an increased likelihood to formulate each of the desired products. Alternatively, manufacturability windows can be used to determine suitability of pre-existing blending components for formulation of desired products.

  • Publication number: 20140274838
    Abstract: A method for improving thermo-oxidative stability and elastomer compatibility in an apparatus lubricated with a lubricating oil by using as the lubricating oil a formulated oil including a lubricating oil base stock. The lubricating oil base stock includes a di-alkylated aromatic base stock of the formula: (R1)—(R2)—(R1) wherein each R1 is the same or different and represents a C10-C30 alkyl group; R2 represents an aromatic moiety. The di-alkylated aromatic base stock includes at least 44 wt % dialkylate product. Thermo-oxidative stability and elastomer compatibility are improved as compared to thermo-oxidative stability and elastomer compatibility achieved using a lubricating oil base stock other than the di-alkylated aromatic base stock. A lubricating oil including the di-alkylated base stock of the above formula, and the di-alkylated aromatic base stock of the above formula.

  • Patent number: 8795112
    Abstract: An oil-free chain is constructed by alternately connecting a pair of outer link plates connected using pins and a pair of inner link plates connected using oil-impregnated bushings into which the adjacent pins of the outer link plates adjacent to the inner link plates are fitted. The oil-impregnated bushings are impregnated with a lubricant having a kinematic viscosity in the range of ISO-VG grade 46 to 460, the weight % of an ingredient having the highest content among the elution ingredients obtained by the GPC method is 95 wt % or more, Mn is 800 or more and 2300 or less, and the ratio of Mw to Mn is 1.0 or more and 1.3 or less. Oil film breakage at the sliding portions of the bushings is suppressed from occurring and the oil film strength is high such that an oil-free chain has a sufficiently long abrasion elongation-resistant life.
