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 present invention relates to a lubricating oil, in particular to a special lubricating oil for rotary kiln supporting wheel bearing pads and a manufacturing method thereof, which is applied to rotary kiln supporting wheel bearing pads with high load and low speed in industries such as alumina, cement, metallurgy, mining, and chemical industry of lubrication. Background technique [0002] Rotary kiln is an important key equipment in alumina, cement, chemical industry, metallurgy and other industries. It has heavy load, high temperature, large dust and humidity, and the operating environment is very harsh. With the current large-scale rotary kiln, the increase in production capacity makes the The pressure per unit area of ​​the bearing pad of the rotary kiln supporting wheel also increases greatly, which makes the lubrication environment of the bearing pad of the supporting wheel of the rotary kiln more harsh, so the requirements for lubricating oil ...
