Solid-liquid phase composite industrial gear oil additive

Abstract

The invention, which belongs to the field of lubricant, particularly relates to a solid-liquid phase composite industrial gear oil additive. According to the theory of solid-liquid phase composite lubrication technology, and aimed at the structure, working conditions, characteristics and the like of an industrial gear, the invention provides a technical scheme for the solid-liquid phase composite industrial gear oil additive composition and a preparation method thereof, the components of the additive include solid lubricant material, liquid medium and other auxiliary materials-dispersing agent, oxidation and corrosion inhibitor, extreme pressure and anti-wear additive, stabilizing and dispersing agent and the like, which are processed into the solid-liquid phase composite industrial gear oil additive with a stable dispersion system by high-speed shearing emulsification, ultrasonic oscillation and sanding dispersion. After being added into industrial gear oil according to a certain proportion, the additive can fill and repair the surface of an industrial gear friction pair during the running process by being attached to the surface to form a stable solid-liquid composite lubricating film. The composite lubricating film can improve the surface lubricating state of the industrial gear friction pair, increase the strength of the oil film, reduce the friction, lower the abrasion, improve the lubricating state, save energy consumption and prolong the service life of gears. The efficiency of the solid-liquid composite lubricating film cannot be reached by any single liquid lubricant or any single solid lubricant.

Description

1. Technical field: [0001] The invention belongs to the field of lubricants, in particular to a solid-liquid phase composite industrial gear oil additive. 2. Background technology: [0002] Lubrication is to add lubricant between the frictional contact surfaces in relative motion, so that a lubricating film is formed between the two contacting surfaces, and the dry friction becomes the internal friction between the molecules inside the lubricant, which has achieved reducing friction, reducing wear and extending the use of mechanical equipment purpose of life. [0003] Lubricants can be roughly divided into the following categories: [0004] 1 Liquid lubricants: including animal and vegetable oils, mineral oils, synthetic oils, water-based liquids, etc. [0005] 2 Semi-solid lubricant: It is a lubricating material - grease that is in a semi-fluid state at room temperature and pressure and has a colloidal structure. [0006] 3 Solid Lubricants: It includes metal compounds s...

Problems solved by technology

The disadvantage is that the oil film strength of the liquid lubricant is not high enough. When the boundary lubrication or the equipment stops running, the liquid lubricant returns to the oil pan (or oil tank). At this time, the thickness of the lubricating film on the friction pair is less than 1um (complete liquid lubrication The thickness of the oil film should be in the range of 2 ~ 10um, and it must be continuous), this thickness cannot completely cover the roughness of the friction surface, let alone completely separate the friction pair, when the equipment is cold started, it will inevitably lead to a sharp increase in the friction coefficient High, the result is the corresponding wear and tear

[0027] Under normal operating conditions, the mechanical efficiency of liquid-lubricated single-stage closed gear transmission is about 97%. When the lubrication is poor, the mechanical efficiency will drop sharply. For example, the efficiency of single-stage gear transmission will drop by 2% (from 97% to 95%). %), the total mechanical efficiency of the reducer with 5-stage gear transmission will drop by 8.5%, which will cause a huge waste of energy and greatly shorten the service life and maintenance cycle of the equipment
