TECHNICAL FIELD

[0001] The utility model relates to bearing production equipment technical field, and the specific field is a bearing ring rotating type cleaning mechanism. BACKGROUND

[0002] As a key basic part in mechanical equipment, the quality level of bearing directly affects the performance and service life of the whole equipment. In the production and processing of bearings, when the bearings are finally assembled, the two rings of the bearing, i.e. the outer ring and the inner ring, need to be cleaned, especially the raceway of the bearing ring, because these raceways are the working surface of the bearing. If there is dust or slag on the working surface of the bearing, it will directly affect the assembly speed of the bearing and the flexibility and service life of the assembled bearing. At present, in the production practice, the cleaning of the bearing ring is mostly by directly putting the bearing into the cleaning equipment and adding cleaning liquid. Since a large number of bearing rings are put in at one time, it is difficult to clean them thoroughly, especially the raceway of the bearing ring, which usually has some impurities and slag. The existing technology, such as the patent with publication number 202323610698.2, discloses a bearing ring cleaning device, which realizes batch cleaning by setting a conveying frame to convey the bearing ring below the spray head.

[0030] The driving assembly 2 comprises a motor 21, a fixing seat 22, a driving wheel and a belt 23; the motor 21 is installed on the upper side of the cleaning tank 3 through the fixing seat 22, the driving wheel is sleeved on the output shaft of the motor 21, the driving wheel is connected with the driven wheel 16 through the belt 23, and the motor 21 can drive the water spraying pipe 11 to rotate around the shaft when the motor 21 works, and the spray head 13 rotates with the water spraying pipe 11.
