[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] In the surface coating process of subway bearings, although the treatment is mainly concentrated on the outer surface of the bearing outer ring, if conventional spraying equipment is used to directly carry out the spraying operation, it is very easy for the spraying powder to penetrate into the working contact area of ​​the bearing balls. After the powder solidifies, the solidified residue inside the contact surface will create significant resistance to the operation of the bearing, thereby interfering with its normal working state and even affecting the reliability of the bearing.

This allows the two storage guide tubes 301 to adjust the spacing according to different bearing widths, thus improving the applicability of the device.

[0046] Working principle:

[0047] In use, connect the inner coating nozzle 205 to the external spray pipe, connect the negative pressure external connector 409 to the external negative pressure pipe, slide the anti-detachment guide seat 206 under the outer split guide cover 203 to separate the outer split guide cover 203 from the inner split guide cover 204, then place the bearing on the surface of the storage guide tube 301 under the inner split guide cover 204, and then slide the anti-detachment guide seat 206 under the outer split guide cover 203 back to its original position so that the storage guide tube 301 under the outer split guide cover 203 is also inserted into the bearing, while ensuring that the synchronous positioning pin 211 is inserted into the synchronous positioning hole 210. At this time, the rubber sealing skirts 305 on both sides block and seal the gap between the outer rings on both sides of the bearing.

[0048] Then, the external guide cone 401 and the closed guide cone 403 are inserted from both sides of the two receiving guide tubes 301 respectively. Then, the external guide cone 401 and the closed guide cone 403 are twisted so that the negative pressure vent 407 is screwed into the docking threaded tube 405 for fixation, thereby docking the two receiving guide tubes 301. When the external guide cone 401 and the closed guide cone 403 are twisted, the first conical surface 402 and the second conical surface 404 will press the pressure inclined surface 310 on both surfaces, thereby causing the positioning slider 303 and the slider base 304 to overcome the elastic force of the reset spring plate 308 and the elastic rubber ring 311 and extend outward, thereby fixing the bearing inner ring with the positioning slider 303.

[0049] Then turn on the negative pressure switch of the external negative pressure pipe, so that the negative pressure extension hose 408 of the external negative pressure pipe can transmit negative pressure, thereby ensuring that the rubber sealing skirt 305 is attracted by the internal negative pressure and tightly adheres to both sides of the bearing outer ring. Then start the suction fan 104, and the suction fan 104 draws air so that the airflow flows downward.

[0050] Then, the switch of the external spray pipe is turned on, so that the spray paint is sprayed at high pressure from the inner tangent paint nozzle 205 onto the surface of the bearing outer ring. Since the airflow is tangent to the surface of the bearing outer ring at this time, the bearing outer ring is impacted and rotated while being sprayed, thereby achieving uniform spraying of the outer ring surface. At the same time, the paint powder scattered by the spraying is sucked into the dust collection box 101 by the suction fan 104. When the bearing outer ring rotates, it will drive the rubber sealing skirt 305 and the rotating ring 312 to rotate synchronously, ensuring that the bearing outer ring can rotate smoothly. At this time, a large amount of paint powder is blocked by the rubber sealing skirt 305, while a small amount of paint powder that can pass through the bottom gap of the rotating ring 312 will be sucked into the center of the bearing inner ring by negative pressure, and then drawn away through the mating threaded pipe 406 and the negative pressure extension hose 408, preventing the powder from entering the working surface of the bearing ball and causing blockage.
