Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically, to a bearing cage oil spraying device. Background Technology

[0002] During bearing operation, there is relative movement between the cage and components such as rolling elements, inner and outer rings. After oil spraying, the oil forms a film on the surface of the cage, reducing the coefficient of friction between the cage and other components, reducing wear, and thus extending the service life of the cage and the entire bearing.

[0003] Large bearing cages are typically exposed to air and are susceptible to corrosion from moisture, oxygen, and other corrosive substances. Oil spraying creates an oil film that isolates the cage from these corrosive substances, preventing rust and maintaining its good appearance and performance.

[0004] However, due to the large radial dimensions of the large bearing cage, it is impossible to spray paint the entire structure. Using segmented spraying makes it difficult to guarantee the coating effect.

[0005] Therefore, how to meet the lubrication and protection requirements of large bearing cages is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a bearing cage oil spraying device to meet the lubrication and protection requirements of large bearing cages.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bearing cage oil spraying device includes a lower oil spraying housing and an upper oil spraying housing, wherein the lower oil spraying housing and the upper oil spraying housing form an oil spraying channel through which a portion of the cleaned bearing cage rotates.

[0009] The oil injection channel is equipped with a spray gun that simultaneously sprays oil onto the inner and outer surfaces of the bearing cage.

[0010] Preferably, in the above-mentioned bearing cage oil spraying equipment, the oil spraying channel is further provided with an oil spraying air knife for blowing air onto the bearing cage after oil spraying.

[0029] This application provides a bearing cage oil spraying device, including a lower oil spraying housing 42 and an upper oil spraying housing 41. The lower and upper oil spraying housings 42 and 41 form an oil spraying channel 43 through which a portion of the cleaned bearing cage 1 rotates. A spray gun is arranged within the oil spraying channel 43 to simultaneously spray oil onto the inner and outer surfaces of the bearing cage. After cleaning, the bearing cage 1 requires surface lubrication and protection through oil application. The oil spraying channel 43, formed by the upper and lower oil spraying housings 41 and 42, allows a segmented portion of the large-sized bearing cage to rotate through the channel, completing oil spraying simultaneously with rotation. The use of a spray gun to simultaneously spray oil onto both the inner and outer surfaces of the bearing cage ensures synchronized oil spraying of the inner and outer rings, forming a uniform oil film and guaranteeing protective capabilities.

[0030] The oil injection unit is also provided with a lower oil injection housing 42 and an upper oil injection housing 41. The lower oil injection housing 42 and the upper oil injection housing 42 form an oil injection channel 43 for the passage of the partially cleaned bearing cage 1. An oil injection area and a drying area are arranged sequentially in the oil injection channel 43, and a partition baffle is provided between the oil injection area and the drying area.

[0031] The oil spraying area is equipped with a lower spray gun 421 for spraying oil onto the inner surface of the bearing cage 1 and an upper spray gun 411 for spraying oil onto the outer surface of the bearing cage 1. The upper spray gun 411 and the lower spray gun 421 simultaneously spray oil onto both the inner and outer surfaces of the bearing cage 1. The cleaning angle of the lower spray gun 421 relative to the inner surface of the bearing cage 1 is set, and the tilt angle of the upper spray gun 411 relative to the outer surface of the bearing cage 1 is set. The spray width and height of the upper spray gun 411 and the lower spray gun 421 are controlled to maximize the spraying area and achieve the best spraying effect on the bearing cage.

[0032] Preferably, the spraying distance between the upper spray gun 411 and the lower spray gun 421 is 130mm to 280mm, more preferably 170mm to 230mm. The spray width of the upper spray gun 411 and the lower spray gun 421 is 120mm to 250mm, more preferably 140mm to 230mm. Both the upper spray gun 411 and the lower spray gun 421 also have adjusting rods supporting the spray gun head 4214. The adjusting rods include a vertically arranged height adjusting rod 4211, a lockable slider 4212 slidably arranged on the height adjusting rod 4211, and a laterally extending angle adjusting rod 4213 extending from the slider 4212. The spray gun head 4214 on the upper spray gun 411 and the lower spray gun 421 is rotatably connected to the angle adjusting rod 4212.

[0033] By setting a height adjustment rod 4211 and an angle adjustment rod 4213 connected by a slider 4212, the oil spraying height and oil spraying angle of the upper spray gun 41 and the lower spray gun 42 are controlled to meet the oil spraying requirements of different types of bearing cages.

[0034] The drying area is also equipped with two sets of oil spraying air knives 44, arranged side by side, with the two sets of oil spraying air knives 44 spaced apart in the rotation direction of the bearing cage 1. Each set of oil spraying air knives 44 includes two knives arranged opposite each other on the inner and outer sides of the bearing cage. Simultaneously, each oil spraying air knife 44 has a strip-shaped air outlet extending along the width direction of the bearing cage 1, allowing for overall air blowing along the width of the bearing cage 1. By using two sets of oil spraying air knives 44 to blow air along the thickness of the bearing cage 1 in two directions, the surface of the bearing cage is simultaneously blown, resulting in a more uniform oil film.

[0035] The oil injection unit also includes an oil injection platform 45, an upper oil injection housing 41 and a lower oil injection housing 42 fixedly mounted on the oil injection platform 45, and an oil injection cabinet 46 arranged on the oil injection platform 45. The oil injection cabinet 46 is located on the side of the oil injection unit away from the bearing cage 1. The upper oil injection housing 41 has ventilation holes 49, specifically arranged on the back side of the upper oil injection housing 41. Correspondingly, the side of the oil injection cabinet 46 is connected to the interior of the upper oil injection housing 41.

[0036] The fuel injection cabinet 46 has multiple layers of mesh 48 inside, with oil filter cotton filling the spaces between adjacent meshes 48. The bottom of the fuel injection cabinet 46 is connected to the ventilation holes 49 on the upper fuel injection housing 41, and a fan 47 is installed on the top of the fuel injection cabinet 46. Preferably, the fan 47 is an axial flow fan, and a conical suction channel is provided on the top of the fuel injection cabinet 46. The axial flow fan provides airflow to the fuel injection channel. During the fuel injection process, the oil mist in the fuel injection channel is extracted and enters the fuel injection cabinet 46 through the ventilation holes 49 of the upper fuel injection housing 41. The oil mist is then filtered by the oil mist filter cotton inside the fuel injection cabinet 46, achieving oil mist recovery.

[0037] A fuel supply system, including a fuel tank and fuel injection pipes connecting the fuel tank to the upper and lower spray guns, is installed on one side of the fuel injection platform 45. The fuel injection platform also has a fuel collection trough 431, located at the bottom of the upper and lower fuel injection housings 41 and 42, to collect fuel mist falling from the bearing cage. An air knife blower is installed on the other side of the fuel injection platform to provide the airflow for the fuel injection air knife.

[0038] The bearing cage oil spraying equipment provided in this application is needed to provide cleaning and rotational support for large-sized bearing cages. Furthermore, this application also provides a bearing cage oil spraying system.

[0039] like Figure 4 As shown, Figure 4 This is a structural layout diagram of the bearing cage oil injection system provided in this application.

[0040] This application provides a bearing cage oil spraying system, including 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 a first side of the cage support platform 2, the cleaning unit 3 having a cleaning channel for accommodating a portion of the bearing cage 1 and cleaning that portion of the bearing cage 1; and an oil spraying unit 4 located on a second side of the cage support platform 2, the oil spraying unit 4 having an oil spraying channel for accommodating a portion of the cleaned bearing cage and spraying oil onto that portion of 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.

[0041] This embodiment provides a bearing cage cleaning and oil spraying device. For large bearing cages 1 with a large radial dimension span, the device simultaneously performs the cleaning of the bearing cage 1 and the oil spraying of the cleaned bearing cage 1.

[0042] From the structural layout of the cleaning and oiling equipment, to accommodate the radial span of the bearing cage 1, the bearing cage 1 is treated by localized cleaning and oiling. 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.

[0043] 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.

[0044] The lifting radius of the cage rotation platform is adjustable, and bearing cages of different inner diameters can be lifted via the support arm. Therefore, the positions of the cleaning unit and the oil injection unit need to be adjusted. In this embodiment, a linear guide rail 5 is also provided at the bottom of the cleaning unit and the oil injection unit. The bottom of both the cleaning unit 3 and the oil injection unit 4 has traveling wheels that cooperate with the linear guide rail. The cleaning unit and the oil injection unit also have brake casters for walking and moving support.

[0045] When adjusting the positions of cleaning unit 3 and oil injection unit 4, release the brake casters of cleaning unit and oil injection unit, push cleaning unit and oil injection unit to move on linear guide rail 5, adjust cleaning unit and oil injection unit to the predetermined position according to the size of bearing cage, and then brake cleaning unit and oil injection unit.

[0046] Then, adjust the lifting arm 22 on the cage rotation platform 2 to extend to the predetermined length, hang the bearing cage 1 to be processed on the hook of the lifting arm, and adjust the bearing cage 1 to fall into the cleaning channel 33 and the oil spraying channel 43, so that the bearing cage 1 can enter the subsequent cleaning process and oil spraying process to process the bearing cage 1.

[0047] In one specific embodiment of this case, a leak-proof tray 6 is also included. The leak-proof tray 6 is laid flat on both sides of the linear guide rail 5 and distributed below the cleaning unit 3 and the oil spraying unit 4. Although the bearing cage 1 is dried by the blower and the oil spraying knife, water droplets or oil may still remain on the bearing cage. By setting up the leak-proof tray, the dripping water droplets and oil are collected, thereby improving the cleanliness of the environment.

[0048] In one specific embodiment of this case, a demagnetizer is also included. The demagnetizer has a demagnetizer frame, and a demagnetizer head is provided on the demagnetizer frame. The demagnetizer head has an inner demagnetizing end face and an outer demagnetizing end face that face the inner and outer sides of the bearing cage. The demagnetizer head is used to perform local demagnetization on the bearing cage, so as to avoid the inability to remove iron filings carried on the surface of the bearing cage.

[0049] Iron filings are removed from the surface of the bearing cage by a demagnetizer. A local cleaning machine is set up to spray the product with 360° high pressure through precision transmission to remove oil and impurities from the product surface. Local air cutting and heating are set up. The product is first air cut to avoid leaving marks due to heating, and then heated to evaporate water stains on the product surface. Oiling is set up to prevent the cage from rusting.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
