Abstract

The invention discloses special lubricating oil of a bearing bush of a supporting roller of a rotary kiln and a manufacturing method thereof. The special lubricating oil contains the following components according to the content by mass percent: 49 to 69 percent of liquid paraffin chlorination and condensation synthetic oil, 15 to 35 percent of poly-alpha-alkene synthetic oil, 0.5 to 1.5 percent of tackifier, 2 to 4 percent of nano colloid molybdenum disulphide powder, 3.5 to 5.5 percent of organic molybdenum complex additive, 2.5 to 4.5 percent of borate complex additive, 1 to 3 percent of additive T406, 0.4 to 0.6 percent of antioxidant T203, 0.7 to 0.9 percent of antioxidant T531 and 0.6 to 0.8 percent of antioxidant T512. The invention has the favorable performances of extreme-pressure resistance, abrasion resistance, high-temperature resistance, water sprinkling resistance and oxidation resistance, can fully act as the functions of repairing the wire drawing of the bearing bush, decreasing the abrasion and lowering the temperature of the bearing bush, prolongs the use period of the bearing bush of the supporting roller and realizes the aims of energy saving and consumption reduction.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a special lubricating oil for a rotary kiln supporting roller bearing bush and a manufacturing method thereof. lubrication. Background technique [0002] Rotary kiln is an important key equipment in alumina, cement, chemical, metallurgy and other industries. It has heavy load, high temperature, large dust, humidity, and a very harsh operating environment. With the current large-scale rotary kiln, the increase in production capacity makes The pressure on the rotary kiln supporting roller bearing per unit area also increases greatly, which makes the lubrication environment of the rotary kiln supporting roller bearing more severe, so the requirements for lubricating oil are also getting higher and higher. At present, most of the rotary kiln supporting roller bearing bushes are lubricated by general cylinder oil or gear oil. Because cylinder oil and gear oil are easy to oxidize, emulsify and det...
