Description

technical field [0001] The invention relates to the technical field of industrial lubricating oil, in particular to an environment-friendly gear lubricating oil and a preparation method thereof. Background technique [0002] Gear transmission is one of the most important transmission methods in machinery. In order to prevent gears from being worn and damaged during work, lubricants (industrial gear oil) are required to separate their working surfaces to maintain the efficiency of the gear mechanism and prolong its service life. According to relevant information, about 54% of mechanical failures are caused by lubrication problems, of which insufficient lubrication and improper lubrication account for 34.4% and 19.6% respectively. The development of industrial gear oil depends on the improvement of base oil processing depth and the improvement of additive performance. The early industrial gear oil in foreign countries is to add fatty oil to the residual oil of the kettle or ...
