COMPOSITE SOLID GREASER FOR RAIL WHEEL FLANGES Russian patent published in 2013 - IPC B61K3/00 C10M169/00 C10M101/00 C10M125/00

Abstract RU 2501693 C1

FIELD: transport.

SUBSTANCE: invention relates to lubricant compositions to be used in operation of rail-mounted vehicles, particularly, to lubing wheel flange-wail pair friction surfaces. Greaser for rail wheel flanges comprises shell filled with composition composed of grease Litol-24 and additives. greaser shell consists of MG-1-grade graphite and filled with lubing composition containing zinc powder with particle size of 0.3-0.5 mcm, graphite powder, autoscoring additive, sulfur-containing lubricant-coolant emulsion and paraffin as a binder at the following ratio of components, wt %: Litol-24 - 42.3±1.5; zinc powder - 33.3±1.5; graphite powder - 3.0±1.0; lubricant-coolant emulsion - 1.6±1>0, paraffin making the rest.

EFFECT: decreased wear and friction factor.
