Abstract

The invention discloses a gear lubricant, which is prepared from the following raw materials in parts by weight: base oil comprising 5-15 parts of esters, 30-50 parts of hydrocarbon and 30-40 parts of three-type base oil, an additive comprising 3-10 parts of an extreme pressure antiwear agent, 2-4 parts of a cleaning agent, 4-6 parts of an oxidation and corrosion inhibitor and 3-8 parts of an anti-friction agent. The esters is one or more of NP343, NP372 and P81, the hydrocarbon is one or more of PA08, PA010 and PA012, the three-type base oil is one or more of 150NN, 100N, 75N and 250N, the extreme pressure antiwear agent is one or more of T323, T321 and T306, the cleaning agent is one or more of T101, T104 and T105, the oxidation and corrosion inhibitor is one or two of T203 and T204, and the anti-friction agent is boron nitrogen compound. The invention has excellent high temperature stability, antioxidation stability, wear-resistance, corrosion resistance and rust resistance. The gear lubricant is added into various gear oil according to the proportion, the viscosity or the viscosity index of the gear oil is slightly changed or not changed, so that the wear resistant, high temperature resistant and press resistant boundary lubricating oil film is formed rapidly when an apparatus is at high speed, low speed, heavy load or impact load.

Description

technical field [0001] The invention belongs to the field of lubricants, in particular to a novel gear lubricant and a preparation method thereof. Background technique [0002] The classification of lubricants are: solid lubricants, liquid lubricants, gas lubricants and semi-solid lubricants. Although there are so many types of lubricants, due to the different types, structures, and operating conditions of equipment, the lubrication methods of equipment and the requirements for lubricants are also different. Especially for the lubrication of all kinds of gear transmission machinery, which was once regarded as a symbol of industrialization, it not only requires that the lubricating oil has good viscosity-temperature properties, but also can maintain a sufficient lubricating oil film under the condition of high temperature friction on the tooth surface, so as not to cause wear. Moreover, it must have sufficient fluidity at low temperature, and there is enough gear oil in the ...
