Abstract

The invention belongs to the field of lubricants and particularly relates to a gear-oil additive, gear lubricating oil, a preparation method and application thereof. The gear-oil additive is preparedfrom the following components in parts by mass: 1-3 parts of nanoscale copper powder, 2-5 parts of nanoscale silicon dioxide, 3-6 parts of nanoscale alumina, 2-5 parts of nanoscale graphite, 1-4 partsof micron-order lead oxide and 3-6 parts of micron-order molybdenum disulfide. The invention also provides the gear lubricating oil containing the gear-oil additive. The gear lubricating oil has thebeneficial effects that not only can the starting wear of a friction pair and the hard friction under the boundary lubricating state be reduced, but also mechanical microrepair and polishing are carried out on pits or bulges on the meshing surface of a gear, the hardness value of the tooth surface of the gear can be increased by about 15%, the value of roughness Ra of the gearing surface is reduced by 5-10% and the vibration noise is reduced 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...
