Abstract

The invention relates to a special gear oil synergist for rolling mills, the components of which are calculated in parts by weight, including 2-30 parts of solid lubricating material composition, 1-10 parts of high-efficiency dispersant, and 1-15 parts of extreme pressure and anti-wear agent , 1-10 parts of high-temperature antioxidant, 35-95 parts of base oil. When in use, add this product to the gear oil of the rolling mill in a relatively small amount to save electricity, extend the service life of the oil, reduce the vibration of the equipment, reduce the mechanical noise, prolong the service life of the equipment, and improve The purpose of mechanical efficiency.

Description

technical field [0001] The invention relates to a gear oil additive, in particular to a special gear oil synergist for rolling mills in large steel mills. Background technique [0002] The lubrication of rolling mills in large steel mills is mainly realized by closed industrial gear oil, and the liquid lubrication of closed industrial gear oils cannot completely solve the poor conditions for the formation of oil film in gear transmission in rolling mills. The contact stress of the tooth surface of the gear is high, and the friction mode Complicated, gear transmission environment temperature is high, dusty, moisture and other conditions caused serious wear and waste of energy and other issues. Contents of the invention [0003] In order to overcome the above-mentioned problems that closed industrial gear oils cannot solve, the present invention adds a synergist containing a solid lubricating material composition to the finished closed industrial gear oil to form a layer of ...
