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. |
