Title:
HEAT REVERSIBLE GEL-LIKE LUBRICATING COMPOSITION, PROCESS FOR PRODUCING THE SAME, AND BEARING LUBRICANT AND BEARING SYSTEM USING SAID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2006/051671
Kind Code:
A1
Abstract:
This invention provides a heat reversible gel-like lubricating composition having such properties that, in a service bulk temperature region, the composition is in a semi-solid gel form as with grease, but on the other hand, in a local high-temperature region such as a sliding contact site, the composition is homogeneously melted, is free from a drawback of grease, i.e., the precipitation of foreign materials, exhibit excellent low frictional characteristics unrealizable by grease, and exhibits significant energy saving properties. The heat reversible gel-like lubricating composition comprises a mineral oil and/or synthetic liquid lubricating base oil and a bisamide and/or a monoamide and has heat reversible gel properties. Preferably, the heat reversible gel-like lubricating composition contains a triamide and further contains, based on 100 parts by weight of the liquid lubricating base oil, 0.01 to 500 parts by weight in total of a bisamide and a monoamide and 0.05 to 10 parts by weight of a friction regulator.
