The present invention relates to a bearing cleaning device, and more particularly, by precisely and uniformly rotating the individual bearings assembled while holding the bearing body while rotating the bearing body when the grease injected into the bearing is finished, and washing with washing liquid and ultrasonic waves. As the grease can be changed by washing, it is possible to reduce the number of manual labors and remove the grease and detergent, which greatly reduces the waste and prevents odors, and prevents accidents. In this case, the cleaning performance is increased and doubled as the cleaning performance is maximized by using the proper arrangement of spray nozzles.

In general, grease should be added to tapered roller bearings to replenish the grease or replace the grease at the end of its service life to maintain the bearing life.

Accordingly, grease and carbonized foreign matter adhered to the bearings by long-term use of the bearings have been manually removed by a worker by hand or cleaned by a general spraying operation.

As described above, since the grease removal operation of the tapered roller bearing is performed by hand, there is a problem that the removal operation situation is difficult and the uncomfortable part cannot be properly performed, resulting in non-uniformity and precise cleaning.

In addition, since the cleaning work of tapered roller bearings is performed by the worker by hand, the cost is increased due to the supply and demand of manpower, and the waste treatment is not carried out at the same time, and the treatment is difficult and the odor is generated by the generation of volatile organic compounds. There was a problem of increasing environmental pollution causing air pollution.

In addition, there is a problem that inadvertent safety accidents because the worker moves while working to wash the large tapered roller bearing.

In addition, since the cleaning operation of the tapered roller bearing is made by the worker, there is a problem in that maintenance efficiency is low due to difficulty in regularly cleaning the bearing due to manpower supply problems.

The present invention has been proposed in order to solve the problems of the prior art presented as described above, the object of the present invention is to rotate the individual bearings while holding the bearing body when the grease injected into the bearing reaches the end of the cleaning liquid By cleaning with supersonic and ultrasonic, it is possible to change grease with precise and uniform cleaning, which can reduce the number of manual labor and separate waste and odor by removing grease and detergent. The service life of the bearing is reduced, and the cost is reduced, and by using the proper arrangement of the spray nozzle, the ultrasonic cleaning performance is maximized, so that the cleaning performance is increased and the bearing is easy to maintain.
