Abstract

The invention belongs to the field of lubricants, and in particular relates to a gear oil additive, a gear lubricating oil and a preparation method and application thereof. The gear oil additive includes the following components in parts by mass: 1-3 parts of nano-scale copper powder, 2-5 parts of nano-scale silicon dioxide, 3-6 parts of nano-scale alumina, 2-3 parts of nano-scale graphite 5 parts, 1 to 4 parts of micron lead oxide and 3 to 6 parts of micron molybdenum disulfide. The present invention also provides a gear lubricating oil containing the above-mentioned gear oil additive. The gear lubricating oil can not only reduce the starting wear of the friction pair and the hard friction under the boundary lubrication state, but also reduce the pits or protrusions on the gear meshing surface. Mechanical micro-repair and polishing can increase the hardness of the gear tooth surface by about 15%, reduce the roughness Ra of the meshing surface by 5-10%, and reduce the vibration noise by 6-11%.

Description

technical field [0001] The invention belongs to the field of lubricants, and in particular relates to a gear oil additive, a gear lubricating oil and a preparation method and application thereof. Background technique [0002] With the rapid development of the machinery industry, along with the improvement and optimization of lubricating oil quality, it is essentially the result of the development of additives. The quality of most lubricating oils is improved by adding a variety of organic or inorganic, liquid or solid additives to improve the performance of lubricating oils, and achieve good lubricating effects through physical or chemical adsorption and chemical reactions with the help of additives. [0003] With the development of micro-nano technology, in the field of lubrication, micro-nano particles have been widely valued in the field of new materials due to their high specific surface area and unique chemical and physical properties, such as the graphene nano-additive...
