Problems solved by technology
In addition, in summer, the instantaneous temperature of the wheel-rail friction point in some sections reaches 400-800°C, and the traditional lubricating grease is burned or evaporated instantly, making it difficult to exert a lasting lubricating effect
At the end of the last century abroad, the solid lubrication technology of wheel flanges has been applied, and the solid lubrication work of wheel rails in relevant domestic units has also entered the application stage. However, due to the immobile nature of solid materials, they cannot meet the requirements of pipeline transportation, so they are limited to vehicle lubrication methods. See applications in the field of ground-mounted rail lubrication

Embodiment 1
[0017] Heat 50 parts of paraffin wax, 20 parts of polyethylene wax and 5 parts of ethylene-propylene copolymer to 160°C-165°C, and stir continuously for 60 minutes until the materials are uniform. Cool to 115°C, add 10 parts of molybdenum disulfide, 3 parts of calcium fluoride, 6 parts of sulfurized olefin cottonseed oil, and 6 parts of nitrogen-containing derivatives of phosphoric acid sulfur, stir evenly, and inject into a mold with an inner cavity size of 220mm×150mm×10.5mm ,forming.
[0018] See the attachment for the on-site coating effect of the above samples figure 2 .
[0019] In summary, the wheel-rail lubricating block involved in the present invention has strong bearing capacity, high temperature resistance, good coating effect, and eliminates the defect of traditional grease that accelerates the growth of wheel-rail fatigue cracks due to the oil wedge effect. Ideal ground rail lubrication material.

Abstract
The invention relates to a lubricating block for a wheelrail. The lubricating block is fixedly arranged on a lubricating device on the lower part of a steel rail and extends upward along the side face of the steel rail from the lower part of the steel rail. When a train passes, the lubricating block is contacted with the rim of the wheel, a lubricating material is smeared on the surface of the rim of the wheel and is carried to the side face of the next curved steel rail through the rim of the wheel, and a mixed lubricating film is formed on the side face of the steel rail to lubricate the wheelrail. The invention relates to formation of the lubricating block, a manufacturing process and a key dimension.
Description
Technical field: [0001] In the field of modern rail transportation, solving the friction problem between wheels and rails and implementing effective lubrication are related to a series of important contents such as locomotive traction energy consumption, driving safety, wheel and rail material consumption and maintenance costs, so it has always been subject to the railway departments of various countries. attention. With the further increase of railway operating speed, the problem of wheel-rail lubrication becomes more and more prominent. If wheel-rail lubrication is an important factor related to operating costs and maintenance costs for existing lines, then for high-speed railways, wheel-rail lubrication is already an important issue related to driving safety and high-speed operation; The problems that must be solved in operation have been paid attention to by designers of heavy-duty express railways in various countries. Background technique: [0002] The wheel-rail lub...
