Problems solved by technology

[0002] With the rapid development of the times, my country's rail locomotives rank among the top in the world. Today's green travel rail locomotives are the first choice. The efficiency, high speed, energy saving, and environmental protection of rail locomotives cannot be replaced by other means of transportation. Existing The running speed of the rail locomotive has reached the aircraft standard, but the high-speed operation of the rail locomotive brings higher challenges to various friction parts, one of which is the wear of the locomotive wheel rim and the rail. Extended service life, reduced maintenance frequency, and reduced transportation costs are essential for continuous and efficient lubrication of locomotive wheels and rails to reduce wear and tear. Only a lubricant with ideal lubricating effect can solve the above defects

Embodiment approach

[0022] A rail locomotive rim lubricating dry-type continuous lubrication rod: raw materials include 40% flake graphite powder, 8% molybdenum disulfide powder, 20% polytetrafluoroethylene particles, 8% polyethylene wax particles, ethylene-vinyl acetate grease 10% granules, 14% tin powder, after mixing and stirring, heating and granulating, making shells, filling and shaping to make dry continuous lubrication sticks;

[0023] The production method of dry continuous lubrication stick is as follows:

[0024] Flake graphite powder: take the leftovers and wastes of flake graphite originals processed by the factory and grind them into granules. In the crushing workshop enclosed by glass curtain walls, workers pour graphite particles into spherical mills through electronic control facilities outside, according to 30-40r / The speed of min is used for impact crushing, and the dust reaching more than 100 meshes is pumped from the inside of the mill to the dust recovery system by the exha...

Abstract

The invention relates to a railway vehicle wheel flange lubrication dry-type continuous lubricating rod, and belongs to the field of lubricants. Efficient lubricity of scale graphite is utilized, molybdenum disulfide serves as a lubricating additive, polytetrafluoroethylene is low in high temperature friction coefficient, polyethylene wax has cold resistance, heat resistance and abrasion resistance, ethylene-vinyl acetate is a viscosity modifier, and the auxiliary material is tin powder with the repair function; the six materials can be prepared into the environmentally-friendly, abrasion-resistant, high-temperature-resistant, deformation-resistant, fluid-free and efficiently-lubricating railway vehicle wheel flange dry-type continuous lubricating rod through special processing, continuous efficient lubricating can be effectively conducted on a railway vehicle wheel flange and a railway, abrasion is reduced, and the maintenance frequency is decreased.
