Anti-oxidation gear oil

Abstract

Disclosed anti-oxidation gear oil is prepared from the following raw materials in parts by weight: 15-22 parts of sodium lauryl polyoxyethylene ether sulfate, 10-17 parts of mineral mixed oil, 2.5-7.3 parts of maleic anhydride, 2.3-6.5 parts of triethanolamineoleate, 2.3-4.6 parts of hendecanedioic acid and 1.2-6.3 parts of potassium borate. Compared with conventional gear oil, the anti-oxidation gear oil has the characteristics of being good in anti-oxidation anti-corrosion property and antirust property, long in oil changing period, capable of reducing discharge of waste oil, exhaust gas and particles, good in biodegradability, relatively low in price compared with conventional lubricating oil; also the anti-oxidation gear oil helps heavy-load industrial gear with high-speed, low-speed, heavy-duty, high-torque or impact load to form a wear-resistant high-temperature-resistant extrusion-resistant boundary lubricating oil film, helps to prevent gear surface from wearing, scratching, gumming, pitting and the like, and helps to prolong the service life of the heavy-load industrial gear.

Description

Technical field [0001] The invention involves an antioxidant gear oil, which is the field of industrial chemical industry. Background technique [0002] At present, the external meshing gear pump, especially the high -pressure gear oil pump at home and abroad, mostly uses cast iron shells and DU bearings.The sealing method of automatic compensation of the axial gap is mainly based on completely isolation of high -pressure oil.MM2 · m / s, the maximum line speed V reaches 10m / s, and due to the insufficient lubricating oil volume, the performance of the DU bearings is not fully utilized, which will cause the bearings to destruct or reduce the service life.short. Invention content [0003] In response to the lack of existing technology, the technical problem to be solved by the present invention is to provide a kind of antioxidant gear oil, which has good antioxidant anticorrosive and anti -rust resistance, long oil replacement cycle, reducing waste oil, waste gas and particulate mat...

AI Technical Summary

Problems solved by technology

[0002]At present, most of the external gear oil pumps at home and abroad, especially high-pressure gear oil pumps, adopt cast iron shells and DU bearing structures, and the DU bearings supporting the journals of the main and slave gear shafts It is an important part that determines the rated pressure and life of the gear pump. However, due to the sealing method of automatic axial clearance compensation, it is mainly to completely isolate the high-pressure oil from the low-pressure bearing chamber. Even if the new DU bearing (carbon steel-based gear pump self-lubricating Bearing) under the condition of oil lubrication, the highest PV value reaches 60N / mm2 m / s, and the maximum linear velocity V reaches 10m / s. Also due to insufficient lubricating oil, the performance of DU bearings cannot be fully utilized, making the bearing Destruction or reduced service life due to ablation, resulting in short service life of high pressure gear pumps
