Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing manufacturing, and specifically relates to a bearing ring cleaning device. Background Technology
[0002] In the field of precision machinery manufacturing, bearings, as core components connecting and supporting rotating parts, play a crucial role in the stability and lifespan of the entire mechanical system due to their performance and reliability. Bearing races, as the basic building blocks of bearings, have a surface cleanliness that is one of the key factors ensuring bearing performance. High-cleanliness bearing races can significantly reduce friction and wear, thereby improving assembly accuracy and effectively extending the service life of the bearing and the equipment it is assembled with.
[0003] Given the importance of bearing race cleanliness, ultrasonic cleaning technology has been widely adopted as the preferred cleaning method in the industry due to its high efficiency, environmental friendliness, and significant cleaning effect. Ultrasonic cleaning technology utilizes the cavitation, acceleration, and direct flow effects induced by high-frequency sound waves in the cleaning fluid to create powerful micro-jet impacts and vibrational energy. This energy can penetrate the tiny gaps on the surface of the bearing races, effectively decomposing and removing oil, metal shavings, and other impurities, thereby achieving a precise and comprehensive cleaning effect.
[0004] During ultrasonic cleaning of bearing races, the races are typically placed on a support rod and then transported one by one into the ultrasonic cleaning tank by a conveyor chain system. However, despite the significant advantages of ultrasonic cleaning technology in cleaning bearing races, the contact area between the bearing races and the support rod is physically obstructed, making it difficult to create sufficient liquid flow and cavitation effects. This results in oil and impurities being difficult to effectively decompose and remove, creating cleaning blind spots. This problem severely affects the cleanliness of the bearing races. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bearing ring cleaning device that solves the problem of incomplete cleaning of the contact area between the bearing ring and the hanging rod.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A bearing ring cleaning device, comprising:
[0008] A cleaning tank, wherein several ultrasonic generators are installed on one side wall of the cleaning tank, the cleaning tank contains cleaning fluid, and a top plate is provided in the middle of the cleaning tank;
[0009] A transmission mechanism is located inside the cleaning tank. The transmission mechanism includes two symmetrically arranged transmission chains. Several transmission sprockets and guide sprockets are rotatably mounted on the side walls of both sides of the cleaning tank. The transmission chains are wound around the transmission sprockets and guide sprockets, and the transmission chains are arranged in a U-shape, so that the bearing rings are submerged inside the cleaning tank when the transmission chain is in motion. The two symmetrical transmission sprockets are connected by a transmission shaft. A motor is located on one side of the cleaning tank, and the output shaft of the motor is connected to the transmission shaft. Several support plates are located on one side of the transmission chains, and each support plate has a shelf plate with a placement groove.
[0010] Hanging rod, used to hang bearing races;
[0011] It also includes a pressure roller assembly for driving the bearing ring to rotate on the hanging rod to expose the contact area between the bearing ring and the hanging rod. The pressure roller assembly includes a roller, and the two sides of the roller are connected to the top plate through connecting rods. When the bearing ring is driven to the lower end of the roller, the roller contacts the outer wall of the bearing ring.
[0012] Furthermore, a number of heating rods are provided on one side wall of the cleaning tank for heating the cleaning solution.
[0013] Furthermore, both ends of the hanging rod are provided with retaining rings, and the diameter of the retaining rings is smaller than the inner diameter of the bearing rings. The retaining rings are placed on both sides of the placement groove.
[0014] Furthermore, connecting plates are provided on the connecting rods on both sides, and a screw is rotatably connected to the upper part of the connecting plate. The screw is threadedly connected to the top plate, and a handwheel is connected to the upper end of the screw.
[0015] Furthermore, a spring is sleeved on the outside of the connecting rod, one end of the spring is connected to the roller frame, and the other end of the spring is connected to the connecting plate. The connecting rod is clearance-fitted with the connecting plate and the top plate.
[0016] Furthermore, it also includes a drying device, which includes several hot air pipes installed on one side of the cleaning tank, and several blowers installed on the hot air pipes. Hot air is blown onto the bearing rings through the blowers to dry the cleaned bearing rings.
[0017] Furthermore, a gear is provided at one end of the hanging rod, and several fixing plates are installed on the side wall of the cleaning tank. One end of the fixing plate is connected to a rack that meshes with the gear, and the rack is located in the cleaning area and the drying area.
[0018] The beneficial effects of this utility model are:
[0019] 1) This utility model sets up a pressure roller assembly inside the cleaning tank to drive the bearing ring to produce a certain displacement on the hanging rod, so as to expose the contact area between the bearing ring and the hanging rod, thus ensuring the cleaning effect of the bearing ring.
[0020] 2) A heating rod is installed inside the cleaning tank to heat the cleaning solution, which accelerates the action of the active ingredients in the cleaning agent, effectively decomposes and removes oil, impurities and residues on the surface of the bearing rings, shortens the cleaning cycle and ensures the cleaning effect of the bearing rings.
[0021] 3) The height of the roller can be adjusted by the screw, making it suitable for cleaning bearing rings of different specifications.
[0022] 4) A spring is installed on the outside of the connecting rod, and there is a clearance fit between the connecting rod, the connecting plate and the top plate. This facilitates the compensation of the roller height adjustment error and effectively avoids damage to the pressure roller assembly or bearing ring caused by the roller directly impacting or excessively pressing the bearing ring due to the roller being too low.
[0023] 5) By setting up a drying device to dry the cleaned bearing rings, corrosion, rust, or secondary pollution caused by moisture and cleaning agent residue are avoided.
[0024] 6) A gear is installed on one side of the hanging rod, and a rack is installed on the side wall of the cleaning box. When the hanging rod is driven to the cleaning area and the drying area, the gear and the rack mesh. When the hanging rod continues to be driven, the hanging rod rotates under the action of the gear and rack, changing the contact point between the bearing ring and the hanging rod, which further ensures the cleaning and drying effect of the bearing ring.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0035] like Figure 1 , Figure 2 As shown, a bearing ring cleaning device includes a cleaning tank 1, a transmission mechanism 2, a hanging rod 3 and a pressure roller assembly 4. Several ultrasonic generators (not shown in the figure) are installed on one side wall of the cleaning tank 1. The cleaning tank 1 is filled with cleaning fluid. A top plate 14 is provided in the middle of the cleaning tank 1.
[0036] like Figure 2 As shown, the transmission mechanism 2 is located inside the cleaning tank 1. The transmission mechanism 2 includes two symmetrically arranged transmission chains 25. Several transmission sprockets 21 and guide sprockets 22 are rotatably mounted on the side walls of both sides of the cleaning tank 1. The transmission chains 25 are wound around the transmission sprockets 21 and guide sprockets 22, and the transmission chains 25 are arranged in a U-shape, so that the bearing rings are submerged inside the cleaning tank when the transmission chain 25 is in motion. The two symmetrical transmission sprockets 21 are connected by a transmission shaft 23. A motor 24 is provided on one side of the cleaning tank 1, and the output shaft of the motor 24 is connected to the transmission shaft 23. Figure 3As shown, a plurality of support plates 26 are provided on one side of the transmission chain 25, and a frame plate 27 is provided on the support plate 26, and a placement groove 28 is provided on the frame plate;
[0037] The hanging rod 3 is used to hang the bearing ring 6;
[0038] The pressure roller assembly 4 is used to drive the bearing ring to rotate on the hanging rod 3, so as to expose the contact area between the bearing ring and the hanging rod 3, such as Figure 5 As shown, the pressure roller assembly 4 includes a roller 41. The two sides of the roller 41 are connected to the top plate 14 through connecting rods 42. When the bearing ring is driven to the lower end of the roller 41, the roller 41 contacts the outer wall of the bearing ring. When the bearing ring continues to be driven, under the interference of the roller 41, the bearing ring and the hanging rod 3 are displaced, exposing the contact area between the bearing ring and the hanging rod 3, thus ensuring the cleaning effect of the bearing ring.
[0039] like Figure 2 As shown, a number of heating rods 11 are provided on one side wall of the cleaning tank 1 to heat the cleaning liquid, which accelerates the action of the active ingredients in the cleaning agent, effectively decomposes and removes oil, impurities and residues on the surface of the bearing ring, shortens the cleaning cycle and ensures the cleaning effect of the bearing ring.
[0040] like Figure 4 As shown, both ends of the hanging rod 3 are provided with retaining rings 31, and the diameter of the retaining rings 31 is smaller than the inner diameter of the bearing ring 6. The retaining rings 31 are placed on both sides of the placement groove 28 to prevent the hanging rod 3 from moving and falling off during the cleaning of the bearing ring.
[0041] like Figure 5 As shown, connecting plates 44 are provided on the connecting rods 42 on both sides. A screw 45 is rotatably connected to the upper part of the connecting plate 44. The screw 45 is threadedly connected to the top plate 14, and a handwheel 46 is connected to the upper end of the screw 45. The height of the roller 41 can be adjusted by rotating the handwheel 46, which is suitable for cleaning bearing rings of different specifications.
[0042] like Figure 5 As shown, a spring 43 is sleeved on the outside of the connecting rod 42. One end of the spring 43 is connected to the roller 41 frame, and the other end of the spring 43 is connected to the connecting plate 44. The connecting rod 42, the connecting plate 44, and the top plate 14 are all clearance fit. The spring 43 is convenient for compensating for the height adjustment error of the roller 41, and effectively avoids the roller 41 from directly hitting or excessively pressing the bearing ring due to the roller being too low, which would cause damage to the pressure roller assembly 4 or the bearing ring.
[0043] like Figure 2 , Figure 7As shown, it also includes a drying device 5, which includes several hot air pipes 51 installed on one side of the cleaning box 1. Several blow nozzles 52 are installed on the hot air pipes 51. Hot air is blown onto the bearing rings 6 through the blow nozzles 52 to dry the cleaned bearing rings, thus avoiding corrosion, rust or secondary pollution caused by moisture and cleaning agent residue.
[0044] like Figure 2 , Figure 4 , Figure 6 As shown, one end of the hanging rod 3 is equipped with a gear 32, and several fixing plates 12 are installed on the side wall of the cleaning box 1. One end of the fixing plate 12 is connected to a rack 13 that meshes with the gear 32. The rack 13 is set in the cleaning area and the drying area. When the hanging rod 3 is driven to the cleaning area and the drying area, the gear 32 meshes with the rack 13. When the hanging rod 3 continues to be driven, the hanging rod 3 rotates under the action of the gear 32 and the rack 13, changing the contact point between the bearing ring and the hanging rod 3, and further ensuring the cleaning and drying effect of the bearing ring.
[0045] During the cleaning of bearing rings, multiple bearing rings 6 are first placed on the hanging rod 3, and then the hanging rod 3 is placed in the placement groove 28, with the retaining ring 31 locking on both sides of the placement groove 28. As the transmission chain 25 drives, the bearing rings are gradually transported into the cleaning fluid and cleaned under the action of ultrasonic waves. During the cleaning process, the pressure roller assembly 4 and the gear 32 rack 13 drive the contact point between the bearing rings and the hanging rod 3, thereby ensuring the cleaning effect of the bearing rings. After cleaning, the bearing rings are transported to the drying area, where hot air blows away the moisture and cleaning agent carried on the bearing rings, preventing corrosion or rust. After the bearing rings are dried, they can be removed to complete the cleaning operation.
[0046] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
