Description

Special solid lubricating rod for subway locomotive

Technical Field

The utility model relates to a solid lubricating rod special for a subway locomotive, in particular to a solid lubricating rod special for a subway locomotive.

Background

At present, 1435mm standard rails are mostly adopted in urban subway rails in China, the weight of each meter of rail is more than 60kg, and 4-8 vehicles are grouped, and the axle weight is more than 13 tons. At present, liquid or semi-fluid lubricant is used as a lubricant for wheel rims of subway rolling stock in China, the lubricant is blown to the wheel rims of the rolling stock by electric power or compressed air serving as power, but airflow generated when a subway train runs at high speed causes the lubricant sprayed by the liquid or semi-fluid lubricant to scatter, so that the train body, train tracks, wheel treads and steel rail treads of the subway train are polluted, the lubricating efficiency between the wheel rims and the steel rails and the traction and braking effects of the rolling stock are reduced, and the liquid and semi-fluid lubricant sprayed by the lubricating device for the wheel rims of the rolling stock are easily positioned inaccurately due to the shaking of the wheels of the rolling stock during running, so that the lubricating effect is influenced, and the working efficiency is reduced. The contact stress of the train wheel rim and the steel rail can reach more than 4000MPa, so that the liquid lubricating oil is easy to generate an oil wedge, and the generated oil wedge accelerates the micro-crack expansion and stripping of the locomotive wheel rim and the locomotive wheel tread due to the action of the oil wedge, thereby seriously influencing the running safety of the subway train. Meanwhile, because the subway is in a relatively closed environment, the traditional liquid lubrication and semi-fluid lubrication have large influence on the environment in the subway, so that the fire prevention difficulty and the maintenance difficulty in the subway are increased, noise is easy to generate, and serious troubles are caused to the relatively closed subway environment. Namely, the solid lubricating rod solves the problems of environmental pollution and oil wedge effect caused by liquid lubrication and semi-fluid lubrication, and prevents the phenomenon of locomotive traction force reduction and slippage caused by 'indiscriminate spraying' of oil mist generated by a liquid lubricant spray head.

However, when the existing solid lubricating rod is not used, a large amount of dust is easily accumulated on the rod core, the time for melting the rod core by the heat generated by the rod core and the wheel rim is increased, the rod core is easily oxidized after being exposed outside for a long time, and when the tail end of the solid lubricating rod is used, the whole solid lubricating rod needs to be disassembled and replaced, so that manpower and material resources are wasted.
