Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 and Figure 2 As shown, Figure 1 Structural layout diagram of the bearing cage cleaning equipment provided in this application; Figure 2 for Figure 1 A schematic diagram of the cleaning structure of the cleaning unit.

[0027] This application provides a bearing cage cleaning device, including a lower cleaning housing and an upper cleaning housing. The lower cleaning housing has a lower cleaning slope corresponding to the slope of the bearing cage, and the upper cleaning housing has an upper cleaning slope corresponding to the slope of the bearing cage. The upper and lower cleaning slopes form a cleaning channel for a portion of the bearing cage to pass through. For large-sized bearing cages, the upper and lower cleaning housings enclose a portion of the bearing cage inside the housing. The upper and lower cleaning slopes correspond to the slope of the bearing cage, creating a cleaning channel within the housing. During the rotation of the bearing cage, localized cleaning is performed on the bearing cage inside the housing. This segmented, localized cleaning method reduces the difficulty of cleaning.

[0028] Specifically, the cleaning unit 3 includes a lower cleaning housing 32 and an upper cleaning housing 31. Both the lower cleaning housing 32 and the upper cleaning housing 31 have a lower cleaning slope and an upper cleaning slope corresponding to the slope of the bearing cage 1. The lower cleaning housing 32 and the upper cleaning housing 31 are arranged opposite to each other through the lower cleaning slope and the upper cleaning slope, and the upper cleaning slope and the lower cleaning slope form a cleaning channel 33 for part of the bearing cage 1 to pass through.

[0029] Both the lower cleaning housing 32 and the upper cleaning housing 31 are hollow structures. In the rotation direction of the bearing cage 1, the bearing cage 1 is rotated into the cleaning inlet 331 of the cleaning channel and rotated out from the cleaning outlet 332. The upper cleaning housing 32 and the lower cleaning housing 31 surround part of the inner ring of the bearing cage 1 inside the housing. Through the interval arrangement of the cleaning inlet 331 and the cleaning outlet 332, part of the arc section of the bearing cage 1 is accommodated.

[0030] A lower cleaning nozzle 321 is arranged inside the lower cleaning housing 32 to spray and clean the inner side of the bearing cage, and an upper cleaning nozzle 311 is arranged inside the upper cleaning housing 31 to spray and clean the outer side of the bearing cage 1.

[0031] Multiple sets of air-drying knives for blowing air onto the bearing cage 1 are also arranged near the cleaning outlet 332 on the lower housing 32 and the upper housing 31. Each air-drying knive includes a strip-shaped air outlet arranged along the width direction of the bearing cage 1, and two sets arranged in parallel along the rotation direction of the bearing cage 1. The two sets of air-drying knives include a lower air-drying knive 341 located on the inner side of the bearing cage 1, and an upper air-drying knive 342 located on the outer side of the bearing cage 1.

[0032] The cleaning unit 3 also includes a cleaning platform 35, with an upper cleaning housing 31 and a lower cleaning housing 32 arranged on the cleaning platform 35. The cleaning platform 35 is also equipped with a circulation pump 37 that connects the upper cleaning nozzle 311 and the lower cleaning nozzle 321 and supplies cleaning fluid. The circulation pump 37 is connected to a cleaning fluid recovery tank inside the cleaning platform 35. The cleaning platform 35 is provided with a cleaning fluid recovery port that connects the interior of the upper cleaning housing 31 and the lower cleaning housing 32 and recovers the liquid sprayed from the cleaning unit.

[0033] The cleaning unit is also equipped with an air knife supply fan 36 connected to the drying air knife. The air knife supply fan 36 has an adjustable air speed and is equipped with a peak-shaving valve to control the air pressure supplied by the drying air knife, thus blowing away moisture and oil stains from the surface of the bearing cage 1. To prevent the spread of the blown oil mist, an oil mist filter is installed on the cleaning platform 35. The oil mist filter is connected to the inside of the axial flow fan to simultaneously extract the blown oil mist, separating and filtering the oil mist and moisture to ensure environmental safety.

[0034] Based on the above-mentioned bearing cage cleaning equipment, this application also provides a bearing cage cleaning oil spraying system using the above-mentioned bearing cage.

[0035] like Figure 3 As shown, Figure 3 This is a system layout diagram for a bearing cage cleaning device.

[0036] The bearing cage cleaning and oil spraying system using bearing cage cleaning equipment further includes a cage support platform 2, arranged radially at the center of the bearing cage 1, and having a rotating seat 21 for suspending the bearing cage 1 radially inward; a cleaning unit 3 located on the first side of the cage support platform 2, the cleaning unit 3 having a cleaning channel for accommodating and cleaning a portion of the bearing cage 1; and an oil spraying unit 4 located on the second side of the cage support platform 2, the oil spraying unit 4 having an oil spraying channel for accommodating the cleaned portion of the bearing cage and for locally spraying oil onto the cleaned bearing cage. The bearing cage 1 is suspended by the cage support platform 2, the bearing cage 1 is arranged laterally in the radial direction, and is rotated by the rotating seat 21. A cleaning unit 3 and an oil spraying unit 4 are installed on the first and second sides of the cage support platform 2. During the rotation of the bearing cage 1, cleaning and oil spraying are performed on it. The cage support platform 2 supports the bearing cage 1 and drives it to rotate synchronously. The cleaning unit 3 and the oil spraying unit 4 perform synchronous cleaning and oil spraying on the rotating bearing cage 1. By supporting the large bearing cage by rotation, the bearing cage is cleaned by local cleaning and oil spraying to meet the cleaning requirements.

[0037] In a preferred embodiment of this invention, the cleaning process and the oil spraying process are respectively located on the first and second sides of the bearing cage's radial direction. The cleaning process involves cleaning unit 3 cleaning the hoisted bearing cage 1. The oil spraying process involves oil spraying unit 4 spraying oil onto the cleaned and dried bearing cage 1. Both cleaning unit 3 and oil spraying unit 4 perform processing on the bearing cage 1 by performing localized machining.

[0038] For large bearing cages 1 with a large radial dimension span, the cleaning of bearing cages 1 and the oil spraying of the cleaned bearing cages 1 are carried out simultaneously.

[0039] From the structural layout of the cleaning and oil spraying system, to accommodate the radial span of the bearing cage 1, the bearing cage 1 is treated by localized cleaning and oil spraying. Specifically, the bearing cage 1 is supported by a cage support platform 2, which includes a platform body and a rotating seat 21 located on top of the platform body. Multiple lifting arms 22 extend evenly from the rotating seat 21. The extended ends of each lifting arm 22 clamp and support the inner ring of the bearing cage 1. At the same time, the rotating structure of the rotating seat 21 allows the bearing cage 1 to rotate according to a predetermined cycle.

[0040] Meanwhile, the cleaning and oiling processes are arranged independently and set on the first and second sides of the bearing cage 1 circumferentially after the bearing cage 1 is installed on the cage support platform 2. The cleaning and oiling processes are set sequentially. After the bearing cage 1 is cleaned, the subsequent oiling process is carried out to spray oil on the bearing cage.
