The invention belongs to the technical field of lubricants; and the provided lubricant for the open gear has good adhesion performance, extreme pressure wear resistance, rust resistance, oxidation resistance and foam resistance.

Description

technical field [0001] The invention belongs to the technical field of lubricants, in particular to an open gear lubricant. Background technique [0002] The transmission form of the open gear transmission mechanism belongs to the involute gear transmission. Among them, the open gear is mainly used in the ball mill in the steel mill, the rotary kiln in the cement plant and the rotary ring gear of the large electric shovel in the mine. At the same time, it is widely used in the gear Rails, chains, cables, rollers, rails and slide rail grooves and other components. The main characteristics of open gear transmission are: heavy load, low speed, large structure size, high tooth surface roughness, and harsh working conditions. Due to the high torques that can be transmitted by open gears, they are often in a state of mixed friction during start-up, normal operation and shutdown, resulting in extremely high stress on the tooth flanks and a shortened service life. In order to exte...
