SU1395656A1 - Oil for lubricating ridges of railway stock wheels - Google Patents

Abstract

The invention relates to lubricating oils, in particular for lubricating the crests of railway wheels. The composition of the oil includes, wt.%: Zinc dialkyldithiophosphate 3-5; 2-mercaptobenzothiazole trichloramine ester 6.5-8.5; isobutylene copolymer with styrene (mol. May. 600) 6.5-8.5; polymethacrylate 1-2; oil product - the rest. As the latter, base oil based on the salt fraction and fuel oil is used. This compound improves anti-wear and anti-wear properties and reduces cold weather temperature. Thus, the mass wear rate of the wheel roller and the rail roller is 0.0087-0.0092 mg / s No. km and 0.015-0.0161 mg / cm-kg, and the setting temperature is (-46) ° C. 2 tab. i (L

This invention relates to a liquid bleaching material used to lubricate the crests of railway rolling stock.

The purpose of the invention is to improve the antiwear, extreme pressure and low temperature properties of the oil.

The oil according to the invention has the following composition, wt.%:

Dialkyldithiophosphate

zinc (DF-P) .3-5

Trichloromethyl I 2-mercapto- ester: benzothiazole

j (LZ-318) 6.5-8.5

I A copolymer of isobutylene i-styrene with a molecular weight of 600-6.6-8-8.5: Lol in vacrylate 1-2; Nefteprodztst Up to 100

The oil used is axial, the base oil is a mixture, the salt fraction (80%) and fuel oil 1 (20%).

: A study of the lubricity of the oil and additives to it was carried out on a serial SMT friction machine using mathematical planning of the experiment. Friction row; wheels on a rail model a roller pair. Duration of experience 7-10 hours

Lubricant to the wheel roller is served in the form of drops.

In tab. 1 shows the content of the components of the proposed and known oils.

In tab. 2 shows the main indicators of manufactured samples.
