The invention discloses a spraying device for rust prevention of a bearing, which has the following working principle: firstly, the door plate 209 is opened, the driving roller wheel 103 is driven to be far away from the clamping table 301, then the bearing 4 is placed on the clamping rods 303 (the inner ring of the bearing 4 is sleeved on the outer sides of the three clamping rods 303), then the contraction of the telescopic rods of the clamping electric cylinders 308 is controlled, so that the stirring rod 307 drives the stirring disc 305 to swing, then the three clamping rods 303 are driven to expand outwards, the bearing 4 is clamped (the three clamping rods 303 are contracted inwards during disassembly), then the adjusting motor 121 is controlled according to the thickness of the bearing 4, the output shaft of the adjusting motor 121 drives the driving gear 122 to rotate, the driving gear 122 rotates to drive the driven gear 120 to rotate, the driven gear 120 rotates to drive the spraying pipe 118 to rotate, the spraying pipe 118 rotates to incline relative to the position shown in fig. 3, when the spraying pipe 118 inclines, the distance between the two ends of the spraying pipe 118, which are close to the bearing 4, and the upper surface and the lower surface of the bearing 4 is reduced, of the spraying pipe 118 and the spraying platform 101 are the largest in the vertical distance between the spraying pipe 118 and the spraying pipe 118 (fan-shaped nozzles are arranged at the two ends of the spraying pipe 118, which are close to the bearing 4). After the bearing 4 is clamped on the clamping rod 303, the driving roller wheel 103 is in contact with the outer ring of the bearing 4, because the traveling permanent magnet 106 and the adjusting permanent magnet 109 repel each other, the traveling permanent magnet 106 applies force to the swing arm 117 through the traveling permanent magnet bracket 107, the swing arm 117 applies force to the driving roller wheel 103, a user can rotate the screw rod 112 by rotating the hand wheel 114, the hand wheel 114 drives the screw rod 112 to rotate and then linearly move on the screw rod bracket 113, at the moment, the screw rod 112 can drag the adjusting slide plate 110 on the adjusting slide rail 116 through the connecting block 111, so that the distance between the traveling permanent magnet 106 and the adjusting permanent magnet 109 is changed, the distance between the traveling permanent magnet 106 and the adjusting permanent magnet 109 is increased, the contact force between the driving roller wheel 103 and the bearing 4 is reduced, and the contact force between the driving roller wheel 103 and the bearing 4 is increased.

When the bearing 4 with the diameter of the outer ring being enlarged or reduced is replaced, the stop positions of the driving roller wheel 103 and the bearing 4 are different when the driving roller wheel is in contact, at the moment, the swing arm 117 swings to drive the input shaft of the gear box 108 to rotate, the output shaft of the gear box 108 drives the spraying pipe support 123 to swing through the belt transmission assembly 124, the spraying pipe support 123 swings to drive the spraying pipe 118 to swing, and the purpose is that the two ends, close to the bearing 4, of the spraying pipe 118 are always located on the upper side and the lower side of the bearing 4, so that spraying uniformity is guaranteed.
