Description

Lubricant film forming paste for railway track and wheel hub
The present invention has narrated a kind of lubricant film forming paste for the railway track and wheel hub use.Belong to novel lubricant.
The weight-carrying capacity of train is big, speed is fast, during motion, can produce high frictional force and intensive rigid shock between the train wheel track, cause the rapid wearing and tearing of wheel track, when train moves on bend, because action of centrifugal force, except above-mentioned interaction, take turns right torsional oscillation, the right transverse excursion of wheel, tread and tread shape the sliding of producing after causing contact at 2 etc. that do not match in addition between wheel track, make that the wearing and tearing between wheel track are more violent.According to statistics, in the wheel of all scrapping, rail, because of wearing and tearing cause useless accounting for more than 55%.The Dearden of early sixties Britain proposes to solve the wearing and tearing of curved steel rail, mainly is line design and adopts lubricated.At present, states such as Japan and the United States, Soviet Union, West Germany all at wheel, adopt that lubricated these countries not only adopt lubricated to reduce wearing and tearing on the rail on curve, and on straight line, also gradually adopted lubricatedly, for example, 90% of Japanese National Railways has all used lubricant.The FAST evidence of experimental centre of transportation of North America railway association (AAR), the oily sufficient lubrication of path curved steel rail is compared with unlubricated, and wearing and tearing are average to improve 80 times, can make wearing and tearing improve more than 20 times to the lubricated of wheel rim.
The wheel-rail lubrication that adopts roughly has two big classes both at home and abroad, and a class is a lubricating oil, and another kind of is lubricating grease.Because the working condition of wheel track is very harsh (the interaction except between wheel track, also be subjected to climatic influences), though oil, lipid lubricant part have been improved the wearing and tearing of wheel track, but under every square centimeter of load and rigid shock, polarization, torsional oscillation, effect of sliding etc. up to several tons, the lipid lubricant is difficult to form good lubricating oil film, even the formation oil film also can be destroyed by the interaction between wheel track very soon.In summer, daylight can make the very fast loss of the grease that remains on the rail again, and thin oil adheres to sand grains easily simultaneously, produces abrasive wear, and, the supporting capacity of lipid lubricant is also lower, generally is no more than 3920N, USP3 for example, 262,679, GB 2,043,684A.Therefore, because the defective of lipid lubricant itself and the harshness of applying working condition condition, the use of lipid lubricant has run into difficulty, the mode that solves increases the oiled number of times often, obviously this will increase expense, even it is believed that increase oiled number of times is still feasible economically, the necessity of wheel-rail lubricating also be described.
The purpose of this invention is to provide a kind of lubricated lubricant-lubricant film forming paste of railway track and wheel hub that adapts to, it also goes for the lubricated of similar railway track and wheel hub working condition, this film forming paste should have low frictional coefficient, high bearing capacity, shock resistance, vibration resistance, the anti-attrition performance is good, regeneration and complementary capabilities also should be arranged, can on wheel track, form good lubricant film, and this film forming paste does not influence its use with the variation of season and temperature.
Content of the present invention:
Lubricant film forming paste for railway track and wheel hub provided by the invention is base oil with the oil petroleum refined by naphthenic, and metallic soap is a viscosifying agent, adds multiple solid lubricant, extreme-pressure additive, friction membrane-forming agent, tackifier etc., presses scientific formula, and the high temperature refining forms.Film forming paste of the present invention adopts grease to make initial lubricant, utilize the synergistic effect between the solid lubricant, and the friction polymerization of superpolymer, make film forming paste very fast formation under frictional force between wheel track and squeezing action contain the solid lubricant film of solid lubricant and polymkeric substance, the solids MoS in this solid lubricant film 2, graphite, boron nitride etc. can partly embed the metallic surface, and the friction polymer in the lubricant film forming paste can make the lubricant particle through the orientation that rubs form even successive high strength solid lubricant film, topped on friction surface, like this, both reduce intermetallic friction, improved its wear resistance again.Another characteristics of lubricant film forming paste of the present invention are that it can constantly form new lubricant film and replenishes the part that is worn in friction process, so it has good friction durability, are particularly useful for lubricated under the similar railway track and wheel hub operating mode.
The preparation of lubricant film forming paste of the present invention:
About 1/3rd and the stearic acid of getting the base oil total amount place reactor, be heated to about 90 ℃, the lithium hydroxide aqueous solution that under constantly stirring, adds 2.5mol slowly, carry out saponification, after finishing, saponification makes that free alkali remains on 0.05-0.15%(weight in the reactant), be warming up to 145-155 ℃ then, add remaining base oil.When temperature reaches 160-170 ℃, add solid lubricants such as molybdenumdisulphide, stir, continue to be warming up to 190-210 ℃, from still, emit reactant, be cooled to about 100 ℃, add tackifier such as Resins, epoxy, the friction membrane-forming agent, extreme-pressure additives etc. stir evenly, and grind.
Base oil during lubricant film forming paste of the present invention is formed can be selected gear oil, locomotive oil or the machinery oil of medium viscosity for use, and it is MoS that metallic soap can be selected lithium soap, soda soap, calcium soap or compound soap, solid lubricant for use 2, graphite, MCA(Dyhard RU 100-cyanogen urea amine complex), PTFE, BN, PbO etc., tackifier are softening temperature less than low-molecular-weight Resins, epoxy or modified epoxy in 50 ℃, the friction membrane-forming agent is Cu 2O, rare earth fluorine, (NH 4) 2HPO 4, Sb 2O 3Deng, by weight, base oil accounts for 50-68%, and metallic soap is 6-15%, solid lubricant 16-31%, tackifier 2-8%, friction membrane-forming agent 3-10%.
Ratio among the present invention between the each component can be by the listed range of table 1, and this variation is a prerequisite with above-mentioned proportionlity.The fundamental property of lubricant film forming paste of the present invention is listed in table 2.

Compared with the prior art the outstanding feature of lubricant film forming paste of the present invention is, has good film forming properties, high supporting capacity and competent work-ing life.Its sintering load on four-ball tester is greater than 7840N, and the lipid lubricant generally is no more than 3920N, on the ring of Timken trier, smear one deck film forming paste, very fast formation one deck solid lubricant film under rubbing effect, this film has the friction durability more than 600 minutes, the lipid lubricant must constantly replenish just can keep operation, and why Here it is will make wheel track keep good lubricating, and the lipid lubricant need increase the reason of smearing number of times.The formed solid lubricant film of film forming paste of the present invention can constantly be replenished in friction process, and dry-film lubricant can not replenish.
Lubricant film forming paste of the present invention was once on probation on four 300 meters sharp radius curves of Longhai Railway track division administration, and result on trial is listed in table 3.
