Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of all-season long-term self-sealing composite solid lubricant for gearboxes, which overcomes 1: there is no lubricant specially applied to gearboxes in the prior art, which causes serious oil leakage, The service life of each part is reduced, the amount of maintenance work is large, and the pollution of groundwater resources is large; 2: The existing various adhesives are used to seal the leaks, but the effect is not ideal; 3: The existing plugging of the leaks Once the adhesive enters the lubricant, it will cause damage to the friction surface and other problems

Abstract

The invention discloses an all-season long-acting self-sealing composite solid lubricant for a gear box. The composite solid lubricant is prepared from base oil, a thickening agent, an antioxidant, atackifier and a composite solid lubricating material, the composite solid lubricating material is composed of flaky graphite, colloidal molybdenum disulfide, polytetrafluoroethylene and yellow lead oxide. The composite solid lubricant comprises the following components in percentage by weight: 10-40% of the thickening agent, 0.2-1.6% of the antioxidant, 4-12% of the tackifier, 8-25% of the flaky graphite, 0.5-5% of the colloidal molybdenum disulfide, 0.5-2% of the polytetrafluoroethylene, 0.5-2% of the yellow lead oxide and the balance of the base oil.

Description

technical field [0001] The invention belongs to the technical field of special lubricating grease and solid lubrication engineering, and in particular relates to an all-season long-acting self-sealing composite solid lubricant for gear boxes. Background technique [0002] Gearbox is a basic transmission device widely used in many industries, and its level and performance directly determine the level and performance of the supporting host. In industries such as mines, ports, wind power and new energy, and metallurgy, gearboxes are often subjected to harsh environments such as extreme temperature differences, wind loads, and high-temperature baking. Oil leakage in these areas is a common contamination and fault in gearbox transmission systems. Oil leakage will increase the amount of lubricating oil used, causing environmental pollution and affecting the lubrication effect of gears, bearings and other boxes, which will intensify the friction between the parts of the motion pai...
