Abstract
The present invention relates to a kind of existing lubrication has the solid friction agent between wheel ﹠ rail that increases the effect of rubbing again, is 5～30% Graphite Powder 99, molybdenum disulphide powder and boron nitride to be mixed sneak into curing molding in 40～90% tetrafluoroethylene, vibrin and the Resins, epoxy after a certain amount of terra alba, talcum powder and the unslaked lime blending evenly.The present invention has improved the locomotive wheel adhesion factor, prevents that rain, snow, greasy weather locomotive wheel from starting and skids during upper and lower slope, has reduced the wearing and tearing of Wheel Steel rail level simultaneously again, reduces train through the out of date noise.
Description
The present invention relates to the lubricated of train wheel rail system, particularly a kind of soft solid friction agent that promptly has lubrication to have again to increase the effect of rubbing.
Metal to-metal contact working order between the train wheel track, not only increase the wearing and tearing of wheel track, and generation harsh noise, and the increase of The friction coefficient travel speed and reducing, when train is static, can be difficult to start because of skidding, particularly can be difficult to because of skidding during descending brake, what address this problem present employing is that the stucco means improve adhesion factor, and this kind method can cause the heavy wear of wheel track.
The objective of the invention is a kind of adhesion factor that can increase locomotive wheel of proposing at above-mentioned deficiency, prevent that rain, snow, greasy weather locomotive wheel from starting and skid when going up a slope, can reduce the solid friction agent between wheel ﹠ rail of wheel and rail surface wear again.
The concrete scheme that realizes the object of the invention is: get Graphite Powder 99, molybdenum disulphide powder and boron nitride are mixed a certain amount of terra alba, talcum powder and unslaked lime, sneak into curing molding in tetrafluoroethylene, vibrin and the Resins, epoxy after the blending evenly, general Graphite Powder 99, molybdenum disulphide powder and boron nitride account for 5～30%, tetrafluoroethylene, vibrin and Resins, epoxy account for 40～90%, in 20～90 ℃ of moulding.
The present invention can make the locomotive wheel adhesion factor improve 8%, and the effective control when having guaranteed train startup, braking, upward slope, descending also can make the abrasion of wheel and rail tread reduce 50% simultaneously, and can reduce train greatly through the out of date noise.
Claims (2)
1, a kind of solid friction agent between wheel ﹠ rail is characterized in that it is with Graphite Powder 99, and molybdenum disulphide powder and boron nitride are sneaked into curing molding in tetrafluoroethylene, vibrin and the Resins, epoxy after mixing a certain amount of terra alba, talcum powder and unslaked lime blending evenly.
2, friction agent according to claim 1 is characterized in that molybdenumdisulphide, Graphite Powder 99, and boron nitride accounts for 5～30%; Tetrafluoroethylene, vibrin and Resins, epoxy account for 40～90%, in 20～90 ℃ of moulding.
