Description
Technical Field

According to statistics of related enterprises, phenomena such as main bearing abrasion and backward movement of a transmission chain occur in a 1.5MW double-fed wind generating set of a certain new energy company in China within 2-3 years of grid-connected operation, the phenomena do not cause enough attention of an owner to follow-up, major equipment faults such as main bearing roller falling, bearing outer ring fracture and the like occur after the wind generating set continues to operate for a few years, and the wind generating set is stopped.
If the faults are repaired, a crane needs to be hired to replace the transmission chain assembly in the air, the field construction is influenced by various aspects such as weather, environment, personnel quality and the like, and the assembly quality is difficult to ensure. If the newly replaced transmission chain assembly and the speed increasing box cannot meet the design requirements, the assembly processes of doping impurities on the installation surface of the main shaft and the speed increasing box, misalignment of the axis of the main shaft and the axis of the locking disc, forced large-torque installation of the locking disc and the like are not controlled, the fault of damage of the main bearing is easily reoccurred in the continuous service process of the fan, secondary faults such as tooth breakage fault inside the speed increasing box and breakage of an elastic supporting rubber body of the speed increasing box can be caused, a huge amount of maintenance cost can be generated in the 20-year service period of the fan, the shutdown time is long, the power generation capacity of the wind power plant is reduced, and the benefit of an owner is lost.
The backward movement phenomenon of a gearbox of a certain domestic fan is mainly caused by the fact that lubricating grease in the main bearing is concentrated on the lower portion of the bearing and is blackened and hardened, the amount of lubricating grease on the upper portion is obviously insufficient, and metal particles exist. The bearing is not well lubricated in the operation process, the blackened lubricating grease can not provide a lubricating protective film for the roller raceway when the bearing operates, the roller is in steel-to-steel contact with the raceway at the film breaking position, a large amount of friction heat is generated during movement, so that the contact surface material is quenched and accompanied with microscopic protrusions, and after the bearing continues to operate, the protrusions are continuously increased to form hard particles which fall into the bearing, so that the bearing is subjected to morphological analysis of early wear of the bearing. If the grease is not cleaned and replaced in the state, the hard metal particles are mixed in the running bearing, the hard particles are pressed into the raceway by the roller, the surface of the raceway is raised, more metal particles fall off, the bearing runs for a long time, and finally the contact surface abrasion of the roller raceway is formed.
