Problems solved by technology

With the continuous development of special industries such as aerospace and military industry, people put forward higher requirements for the performance of lubricating materials, while traditional liquid lubricants require special supporting equipment, which have high cost and large consumption, and do not meet the requirements of environmental protection, energy saving, technical Innovation, the damage and blockage of the grease and oil Louis lead to insufficient lubrication of the locomotive wheel rim and different degrees of wear, which are difficult to meet the requirements. In order to obtain extreme work such as ultra-high temperature, ultra-low temperature, high pressure, high vacuum, high load and strong radiation Lubricating materials that can still function normally in the environment, solid lubricants have gradually become the first choice

Abstract

The invention discloses a railway locomotive wheel rail solid lubricating block and a preparation method thereof. The solid lubricating block comprises a lubricating rod (1), a boss (2) and a groove (3), wherein the boss (2) is arranged at one end of the lubricating rod (1), the groove (3) is formed in the other end of the lubricating rod (1), the four edge corners of the boss (2) are respectively in smooth transition, the side surface of the boss (2) is in chamfering connection with the plane of the lubricating rod (1), the four edge corners of the groove (3) are respectively in smooth transition, the side surface of the groove (3) is in chamfering connection with the plane of the lubricating rod (1), and one side surface of the lubricating rod (1) is provided with waves which are matched with a material delivery belt. The solid lubricating block has the advantages that the surface of the lubricating rod (1) is provided with the waves which are matched with the material delivery belt, and the groove is formed in one end of the lubricating rod, so the installation and replacement are convenient, and the easiness in falling is avoided; the connecting plane of the groove and the lubricating rod and the connecting plane of the boss and the lubricating rod respectively adopt the chamfering connection, and the edge corners of the groove and the boss are respectively in smooth transition, so the installation is convenient, the friction between the lubricating block and equipment is reduced, and the abrasion of equipment is decreased.

Description

technical field [0001] The invention relates to a wheel-rail lubricant, in particular to a railway locomotive wheel-rail solid lubricating block. Background technique [0002] With the large number of internal combustion and electric locomotives on the road and the development of railways in the direction of speed increase and heavy load, the side wear of curved steel rails on my country's busy main railway lines is on the rise, and the problem of wheel and rail wear is becoming more and more prominent; during the "Ninth Five-Year Plan" period of Jinan Railway Bureau A total of 185km of rails with curved wear exceeding the limit were replaced, accounting for 43.5% of the total number of damaged rails replaced. The shortest service life of small-radius curved carbon rails on busy trunk lines is only 10 months, and the total weight of passing through is 70Mt km / km, which is the normal service life of rails. The service life of rare earth rails on the R=600m curve of Jinpu Line i...
