Description

Technical Field

[0001] The present invention relates to the technical field of hub bearing processing equipment, and particularly to a conveying device and a method for cross-equipment conveying of the inner ring of a hub bearing. Background Art

[0002] Currently, the production process of hub bearings mainly includes forging or stamping of raw materials, heat treatment to improve hardness and wear resistance, precision machining to ensure dimensional accuracy and surface finish, polishing and cleaning of raceways, anti-rust passivation treatment, manufacturing of cages (stamping or plastic molding), assembly of inner and outer rings and rolling elements, filling and sealing of grease, and finally strict performance testing and quality inspection to ensure that the products meet the standards.

[0003] Currently, the polishing, cleaning, anti-rust, and passivation treatment of bearing hubs are usually achieved by a polishing and cleaning machine and an anti-rust passivation device. However, the metal surface after polishing and cleaning has high activity and is prone to electrochemical corrosion, such as pitting corrosion, in a humid or salty environment. Therefore, when transferring the hub bearing between the polishing and cleaning machine and the anti-rust passivation device, it may adsorb pollutants such as dust and sweat, resulting in increased wear during subsequent installation or operation.

[0004] The existing methods for conveying the inner ring of hub bearings mostly use a combination of a conveyor belt system and a feeding chute. However, this method has the following disadvantages: the hub bearings slide in the feeding chute, and the downward sliding speed is difficult to effectively control, and they are extremely prone to collide with each other, resulting in damage to the product quality. Summary of the Invention

[0005] The present application provides a conveying device and a method for cross-equipment conveying of the inner ring of a hub bearing, which have the function of efficiently transferring the hub bearing after polishing and cleaning into the anti-rust passivation device on the premise of reducing the mutual wear and impact during feeding.

A roller is arranged at the end of the eccentric rod, and the roller is in contact with the outer surface of the flexible peristaltic sleeve. The circumferential movement of the roller causes the flexible peristaltic sleeve to perform intermittent peristalsis to slow down the sliding speed of the hub bearing.

[0007] Preferably, the peristaltic component includes a substrate, the substrate is installed on the first bottom plate, a flexible peristaltic sleeve is arranged on the substrate, the material of the flexible peristaltic sleeve is silicone, and an arc-shaped contact surface imitating the laryngeal tube is arranged on the inner surface of the flexible peristaltic sleeve; The peristaltic component further includes a driving motor and a plurality of rotating shafts that can rotate synchronously in the same direction. The driving motor is used to drive the plurality of rotating shafts, and a linkage is arranged between the output end of the driving motor and the rotating shaft for synchronously driving the rotating shaft to rotate in the same direction. Through the synchronous driving of the plurality of rotating shafts by the driving motor and the linkage, the eccentric rod arranged on the rotating shaft performs a circumferential movement. A roller is arranged at one end of the eccentric rod, and the roller is in contact with the outer surface of the flexible peristaltic sleeve, causing the flexible peristaltic sleeve to perform intermittent peristalsis.

[0008] Preferably, an internal cavity is formed between the flexible peristaltic sleeve and the substrate. A sandwich layer is arranged in the internal cavity of the flexible peristaltic sleeve. The material of the sandwich layer is the same as that of the flexible peristaltic sleeve, and both are silicone. The sandwich layer divides the internal cavity of the flexible peristaltic sleeve into independent first and second sealed cavities. The first sealed cavity is close to the roller, and a plurality of alloy support bars are wrapped inside the first sealed cavity. The alloy support bars are strip-shaped structures perpendicular to the substrate, and the alloy support bars and the sandwich layer are adhesively arranged.

[0009] Preferably, a liquid release component for releasing lubricating oil on the arc-shaped contact surface of the flexible peristaltic sleeve is arranged inside the second sealed cavity.

[0010] Preferably, the liquid release component includes a main hose parallel to the substrate. One end of the main hose is blocked, and the other end of the main hose is connected to a lubricating oil supply component for supplying lubricating oil. The main hose is distributed in a snake shape inside the second sealed cavity. A plurality of sub-hoses are arranged on the upper surface of the main hose. A plurality of drip tubes are communicated with the sub-hoses. The plurality of drip tubes are equally spaced along the longitudinal direction of the sub-hose. One end of the drip tube is communicated with the sub-hose, and the other end of the drip tube penetrates and extends to the arc-shaped contact surface of the flexible peristaltic sleeve.

[0011] Preferably, a spherical hollow sac is connected to the end of the drip tube far from the sub-hose. The spherical hollow sac is communicated with the drip tube, and a cross opening is arranged on the spherical middle sac.

[0012] Preferably, an arc-shaped guide plate is provided at the output end of the output groove. A steering groove is provided directly below the arc-shaped guide plate. The hub bearing output from the output groove is guided to the inside of the steering groove through the arc-shaped guide plate. Specifically, the steering groove includes a second bottom plate. Two second side plates are provided on the upper surface of the second bottom plate. An arc-shaped guide groove is formed between the two second side plates. A telescopic shovel plate is provided at the end of the guide groove and close to the arc-shaped guide plate. The shovel plate is driven by an electric telescopic rod. Under the action of the shovel plate, the sliding hub bearing is flipped by 90°, so that the radial surface of the hub bearing rolls inside the steering groove.

[0013] Preferably, a guiding path is formed inside the guiding groove along the rolling direction of the hub bearing. A number of flexible guiding sleeves are evenly arranged on the inner side walls of the two second side plates along the guiding path. The material of the flexible guiding sleeve is silica gel. A vibrating plate is provided inside the inner cavity of the flexible guiding sleeve. The vibrating plate is used to generate intermittent and regular vibrations. One end of the vibrating plate is blocked inside the flexible guiding sleeve, and the other end of the vibrating plate is connected to the output end of a vibrating motor.

[0014] Preferably, a guiding rail is further provided on the rust prevention and passivation device. A discharge hole is provided inside the guiding rail. An input groove inclined downward is provided between the discharge hole and the input end of the rust prevention and passivation device. The guiding end of the guiding groove faces the guiding rail. The guiding groove moves up and down inside the guiding rail. A linear motor for driving the guiding groove to move up and down is provided between the guiding groove and the guiding rail. When the guiding groove moves upward through the linear motor until the output end of the guiding groove coincides with the discharge hole, the hub bearing inside the guiding groove will be guided along the input groove into the rust prevention and passivation device. This step-by-step feeding method can avoid problems such as blockage or inaccurate positioning caused by one-time feeding.

[0015] Preferably, a method for cross-device conveying of the inner ring of a hub bearing, based on the above-mentioned conveying device, the steps of conveying the hub bearing include: S1: The polished and cleaned hub bearing is placed into the inclined trough body through the clamping assembly. Its axial end face fits against the bottom plate and slides along the inside of the trough body; S2: The driving motor synchronously drives the rotating shaft to drive the eccentric rod to perform a circular motion; the roller at the end of the eccentric rod fits against the outer surface of the flexible peristaltic sleeve, simulating the "throat swallowing" action, so that the peristaltic sleeve peristals intermittently, generating frictional force and slowing down the sliding speed of the hub bearing; S3: The roller applies pressure to form a positive pressure inside the main hose, ensuring that the lubricating oil overcomes the resistance and flows into the sub-hoses, realizing the diversion of the lubricating oil; the flexible peristaltic sleeve simulates the "throat saliva" movement, ensuring continuous lubrication of the arc-shaped contact surface and avoiding dry friction; S4: The hub bearing of the output slot slides down due to inertia or gravity, enters the guiding groove through the arc-shaped guiding plate and approaches the shovel plate; the electric telescopic rod drives the shovel plate to extend, blocks the sliding of the hub bearing, and uses the shovel plate to turn it by 90°, so that the radial surface of the hub bearing rolls in the turning groove; S5: When a certain number of hub bearings accumulate in the guiding groove, the linear motor drives the guiding groove to rise, aligns its output end with the discharge hole, and the hub bearings are introduced into the rust-proof passivation device along the input groove.

[0016] In summary, the present application has the following beneficial effects: 1. By adjusting the power of the driving motor, the rotation speed of the rotating shaft is adjusted, so that the discharge speed of the hub bearing can be accurately controlled, avoiding the impact caused by too fast speed. By controlling the discharge speed, the distance between adjacent hub bearings can be increased, reducing or avoiding their collision during sliding. Reducing impact and wear helps to maintain the polishing quality of the hub bearing and ensure the effect of subsequent rust-proof passivation treatment. Although the sliding speed of a single hub bearing is reduced, through smoother and more controllable transportation, the downtime caused by problems such as impact and jamming can be reduced, and the transportation efficiency can be improved as a whole. In short, this peristaltic component simulates the action of the throat swallowing, realizing the buffering, deceleration and separation of the hub bearing, thus improving the transportation quality and efficiency; 2. The setting of the sandwich layer divides the built-in cavity into independent areas, realizing the precise control of the pressure in different areas. The first sealing cavity wraps the alloy support bar, directly receives the acting force of the roller, and transmits the force through the alloy bar. Imitating the "muscles of the pharynx": the goal of the whole device is to imitate the peristalsis of the pharyngeal muscles through the above structure and movement mode. The guiding function of the hub bearing will be realized.

[0017] 3. By imitating the "throat saliva", the function of the "throat saliva" is to lubricate the esophagus, making it easier for food to pass through and reducing friction and resistance. Here, following this principle, lubricating oil is released on the arc-shaped contact surface of the flexible peristaltic sleeve, aiming to reduce the friction between the flexible peristaltic sleeve and the hub bearing. Through lubrication, the dry friction on the surfaces of the peristaltic sleeve and the hub bearing can be effectively reduced or even eliminated. Dry friction will lead to an increase in resistance, resulting in jamming. The addition of lubricating oil changes the dry friction into liquid friction, greatly reducing the friction coefficient and making the movement smoother.

[0018] 4. "Peristalsis" and "lubrication" are synchronized: the "peristaltic" action of the flexible peristaltic sleeve is synchronized with the release of "lubricating oil" from the dropping point tube. This means that while the flexible peristaltic sleeve is moving, the arc-shaped contact surface of the flexible peristaltic sleeve can always obtain lubrication, avoiding dry friction.

[0019] 5. The vibration motor drives the vibration plate to generate intermittent and regular vibrations. The regular vibrations will finely adjust the position of the hub bearing to avoid the hub bearing hitting the inner surface of the second side plate when turning in the arc-shaped guiding groove, reducing wear and enabling them to be more evenly distributed on the guiding path, improving the load-bearing capacity and service life.

Detailed Embodiments

[0021] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following detailed embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Embodiment 1. The present invention discloses a conveying device and a method for cross-device transportation of the inner ring of a hub bearing. Among them, the conveying device is used to transfer the hub bearing in the polishing and cleaning machine 1 to the inside of the rust prevention and passivation device 2. The output end of the polishing and cleaning machine 1 is located below the input end of the rust prevention and passivation device 2. Through the conveying device, on the premise of reducing the mutual wear and impact of the hub bearings during feeding, the polished and cleaned hub bearings are efficiently transferred to the inside of the rust prevention and passivation device 2, as Figure 1As shown, it includes an output groove 3 provided at the output end of the polishing and cleaning machine 1 and an input groove 4 provided at the input end of the rust prevention and passivation device 2.

[0023] As Figure 2 shown, further, the output groove 3 includes a first bottom plate 301 with an angle of 15° with the horizontal plane and two first side plates 302 fixed on the upper surface of the first bottom plate 301. A downwardly inclined groove body 303 is formed between the two first side plates 302 and the first bottom plate 301. The hub bearing polished and cleaned by the polishing and cleaning machine 1 will have its internal clamping assembly placed inside the groove body 303. At this time, the axial end face of the hub bearing fits the upper surface of the first bottom plate 301, and under the action of the inclination of the groove body 303, the hub bearing slides downward along the internal space of the groove body 303.

[0024] As Figure 2 shown, during the downward sliding process of the hub bearing, adjacent two hub bearings will collide with each other during the discharging sliding process, and the sliding discharging speed is difficult to control, affecting the transfer quality of the hub bearing after polishing. Therefore, a peristaltic component 5 is provided on the inner side surfaces of the two first side plates 302, which is used to imitate the "throat swallowing method" to control the sliding discharging speed of the hub bearing and avoid the collision between the hub bearings.

[0025] As Figure 2 and Figure 3 shown, specifically, the peristaltic component 5 includes a substrate 501. Among them, the substrate 501 is installed on the first bottom plate 301, and a flexible peristaltic sleeve 502 is provided on the substrate 501. The substrate 501 is used to fix the flexible peristaltic sleeve 502 to ensure the stability of the peristalsis of the flexible peristaltic sleeve 502. The material of the flexible peristaltic sleeve 502 is silicone. The flexible peristaltic sleeve 502 is a key component, and the silicone material endows it with good elastic deformation ability. And an arc-shaped contact surface imitating the laryngeal tube is provided on the inner surface of the flexible peristaltic sleeve 502, which is the part in direct contact with the hub bearing. The arc design fits the surface of the hub bearing better, increases the contact area, thereby providing more uniform friction force. The relatively soft flexible silicone material can reduce the wear on the surface of the hub bearing. The arc-shaped contact surface imitating the laryngeal tube can also disperse the pressure more evenly and avoid local stress concentration. Moreover, the thickness of the arc-shaped contact surface of the flexible peristaltic sleeve 502 is greater than the thickness of other parts of itself. By increasing the thickness of the contact surface, the wear resistance and strength of the flexible peristaltic sleeve 502 at the arc-shaped contact surface part are improved to bear the pressure and friction of the hub bearing. At the same time, the thickness difference may also affect the deformation mode of the peristaltic sleeve, making it easier to produce a swallowing-like action.

[0026] As Figure 4As shown, the peristaltic swallowing component 5 further includes a driving motor and several rotating shafts 503 that can rotate synchronously in the same direction. The driving motor is used to drive the several rotating shafts 503, and a linkage is provided between the output end of the driving motor and the rotating shafts 503. Specifically, the linkage includes a pulley provided at the bottom of the rotating shaft 503 and coaxially connected thereto. The several pulleys are connected by a belt, and the output end of the driving motor is connected to the center point at the bottom of any one of the pulleys. By synchronously driving the several rotating shafts 503 by the driving motor, the eccentric rod 504 provided on the rotating shaft 503 performs a circular motion. A roller 505 is provided at one end of the eccentric rod 504, and the roller 505 fits against the outer surface of the flexible peristaltic sleeve 502, causing the flexible peristaltic sleeve 502 to perform intermittent peristalsis, so that the flexible peristaltic sleeve 502 can generate frictional force on the hub bearing and slow down its sliding speed. By adjusting the power of the driving motor and the rotation speed of the rotating shaft 503, the discharging speed of the hub bearing can be precisely controlled to avoid the impact caused by too fast a speed. By controlling the discharging speed, the distance between adjacent hub bearings can be increased, reducing or avoiding their collision during the sliding process. Reducing collisions and wear helps to maintain the polishing quality of the hub bearing and ensure the effect of subsequent anti-rust passivation treatment. Although the sliding speed of a single hub bearing is reduced, through a smoother and more controllable transfer, the downtime caused by problems such as impact and jamming can be reduced, improving the transfer efficiency as a whole.

[0027] Briefly speaking, this peristaltic swallowing component 5 realizes the buffering, deceleration and separation of the hub bearing by simulating the action of throat swallowing, thus improving the transfer quality and efficiency.

[0028] As Figure 4As shown, a built-in cavity is formed between the flexible peristaltic sleeve 502 and the substrate 501, and an interlayer 506 is arranged in the built-in cavity of the flexible peristaltic sleeve 502. The material of the interlayer 506 is the same as that of the flexible peristaltic sleeve 502, and both are silicone. The interlayer 506 separates the built-in cavity of the flexible peristaltic sleeve 502 into a first sealed cavity and a second sealed cavity that are independent of each other. The silicone interlayer 506 separates the built-in cavity into a first sealed cavity and a second sealed cavity that are independent of each other; this allows independent control of different areas and more finely simulates the movement of the "throat muscles". Among them, the first sealed cavity is close to the roller 505, and the interior of the first sealed cavity is wrapped with a plurality of alloy support bars 507. The alloy support bar 507 is a long strip structure perpendicular to the substrate 501. The alloy support bar 507 and the interlayer 506 are bonded. When the roller 505 swings, the alloy support bar 507 is subjected to pressure to provide support for the interlayer 506. This support can be understood as the role of "skeleton", which enables the flexible structure to maintain a specific shape and direction when subjected to force, rather than deforming randomly. The intermittent swing of the roller 505 is the driving mechanism. By applying pressure to the alloy support bar 507, directional pressure is applied to the flexible peristaltic sleeve 502. This simulates the thrust generated by the contraction of the throat muscles.

[0029] like Figure 4 As shown, the roller 505 provides power, and the alloy support bar 507 converts the power into directional pressure, which together realizes precise peristaltic motion.

[0030] like Figure 4 As shown, the muscles in the throat push food or liquid downward by rhythmic contraction and relaxation, which is peristalsis. The device controls the pressure changes in the first and second sealed chambers to make the flexible peristaltic sleeve 502 produce similar peristaltic motion. Among them, the role of the alloy support bar 507 is crucial. When the rotating shaft 503 swings and applies pressure to the alloy support bar 507 in the interlayer 506, the support bar disperses the pressure and transmits it to the flexible peristaltic sleeve 502 in a directional manner. This directional pressure simulates the directionality of the throat muscle contraction.

[0031] like Figure 4 As shown, the function of the interlayer 506 is to divide the built-in cavity into independent areas to achieve precise control of the pressure in different areas. The first sealed cavity wraps the alloy support bar 507, which is directly subjected to the force of the roller 505 and transmits the force through the alloy bar. Imitation of "throat muscles": The goal of the entire device is to imitate the peristalsis of the throat muscles through the above structure and movement mode. The guiding function of the hub bearing will be realized.

[0032] like Figure 4As shown, there is a liquid release component 6 inside the second sealing cavity for releasing lubricating oil on the arc-shaped contact surface of the flexible peristaltic sleeve 502. The liquid release component 6 is used to release lubricating oil on the arc-shaped contact surface of the flexible peristaltic sleeve 502. By imitating "throat saliva", the function of "throat saliva" is to lubricate the esophagus, making it easier for food to pass through, reducing friction and resistance. Here, following this principle, lubricating oil is released on the arc-shaped contact surface of the flexible peristaltic sleeve 502, aiming to reduce the friction between the flexible peristaltic sleeve 502 and the hub bearing. Through lubrication, the dry friction on the surface of the peristaltic sleeve and the hub bearing can be effectively reduced or even eliminated. Dry friction will lead to an increase in resistance, resulting in a jamming phenomenon. The addition of lubricating oil transforms the dry friction into liquid friction, greatly reducing the friction coefficient and making the movement smoother.

[0033] As Figure 4 shown, moreover, the function of the liquid release component 6 is to evenly distribute the lubricating oil on the surface of the hub bearing. An even lubricating film can provide a more effective friction reduction effect and avoid wear or oxidation caused by insufficient local lubrication. The surface of the hub bearing is very clean after polishing and cleaning, but it is also more vulnerable to oxidation. The lubricating oil can form a protective film to isolate oxygen and moisture, thus effectively preventing the surface of the hub bearing from rusting due to oxidation.

[0034] As Figure 4 shown, in short, this design improves the performance and lifespan of the device by reducing friction through lubrication, preventing jamming, and providing oxidation protection.

[0035] As Figure 4 shown, the liquid release component 6 includes a main hose 601 parallel to the substrate 501. One end of the main hose 601 is blocked, and the other end of the main hose 601 is connected to a lubricating oil supply component for supplying lubricating oil. The main hose 601 is serpentinely distributed inside the second sealing cavity. A number of sub-hoses 602 are arranged on the upper surface of the main hose 601. A number of drip tubes 603 are connected to the sub-hoses 602. The number of drip tubes 603 is equally spaced along the longitudinal direction of the sub-hose 602. One end of the drip tube 603 is connected to the sub-hose 602, and the other end of the drip tube 603 penetrates and extends to the arc-shaped contact surface of the flexible peristaltic sleeve 502.

[0036] As Figure 4As shown, the main hose 601 is serpentinely distributed, increasing the flow path of the lubricating oil and facilitating the stability of the oil pressure. Under the pressure of the alloy support bar 507, a positive pressure is formed inside the main hose 601, ensuring that the lubricating oil can overcome the resistance and smoothly flow from the main hose 601 to the branch hoses 602. The branch hoses 602 are branched from the main hose 601, acting as multiple branches to disperse the lubricating oil in the main hose 601, providing a basis for uniform oil dripping. The equally spaced drip tubes 603 are the final link for the release of the lubricating oil. The outlets of the drip tubes 603 directly face the arc-shaped contact surface of the flexible peristaltic sleeve 502, enabling the precise dripping of the lubricating oil onto the parts that need lubrication.

[0037] As Figure 4 shown, "peristalsis" and "lubrication" are synchronized: the "peristaltic" movement of the flexible peristaltic sleeve 502 is synchronized with the release of "lubricating oil" from the drip tubes 603. This means that while the flexible peristaltic sleeve 502 is moving, the arc-shaped contact surface of the flexible peristaltic sleeve 502 can always be lubricated, avoiding dry friction.

[0038] As Figure 4 shown, through the design of the serpentine main hose 601, branch hoses 602, and equally spaced drip tubes 603, the lubricating oil can be evenly distributed on the entire arc-shaped contact surface of the flexible peristaltic sleeve 502. Compared with direct spraying or immersion, this method is more precise and controllable, avoiding waste of lubricating oil and insufficient local lubrication.

[0039] As Figure 4 shown, specifically, one end of the drip tube 603 far from the branch hose 602 is connected to a spherical hollow capsule 604. The spherical hollow capsule 604 is interconnected with the drip tube 603, and a cross-shaped opening is provided on the spherical capsule. The spherical hollow capsule 604 serves as a micro-oil reservoir and can store a small amount of lubricating oil. At the same time, the elastic deformation of the spherical hollow capsule 604 can play a buffering role, absorbing the pressure fluctuations in the main hose 601 and maintaining the stability of the pressure at the outlet of the drip tube 603. The cross-shaped opening forms four small release channels on the surface of the capsule. Under the action of pressure, the lubricating oil slowly and evenly seeps out through these four channels. This design avoids a large amount of lubricating oil dripping at once, ensuring the continuity and uniformity of lubrication. Even if there are tiny impurities entering the drip tube 603, the structure of the spherical hollow capsule 604 and the cross-shaped opening can reduce the possibility of blockage. The impurities may be captured by the capsule or washed away through the cross-shaped opening.

[0040] Embodiment 2, as Figure 5As shown, an arc-shaped guide plate 7 is provided at the output end of the output groove 3. A turning groove 8 is provided directly below the arc-shaped guide plate 7. The hub bearings output from the output groove 3 are guided by the arc-shaped guide plate 7 into the interior of the turning groove 8. Specifically, the turning groove 8 includes a second bottom plate 801. Two second side plates 802 are provided on the upper surface of the second bottom plate 801. An arc-shaped guide groove is formed between the two second side plates 802. A telescopic shovel plate 803 is provided at the end of the guide groove and near the arc-shaped guide plate 7. The shovel plate 803 is driven by an electric telescopic rod. Under the action of the shovel plate 803, the sliding hub bearing is flipped by 90°, so that the radial surface of the hub bearing rolls inside the turning groove 8. Specifically, the hub bearings coming out of the output groove 3 will slide down at a certain speed due to inertia or gravity. When the hub bearing falls near the shovel plate 803, the shovel plate 803 extends under the drive of the electric telescopic rod to block the continued sliding of the hub bearing. Due to the certain angle or arc of the shovel plate 803, the hub bearing will be forced to tilt upward or sideways while being blocked. The design of the shovel plate 803 enables the hub bearing to no longer slide on its end face, but the radial surface on the side contacts the inner wall of the turning groove 8, thereby realizing the change of the rolling direction. The flipped hub bearing can continue to roll along the new direction.

[0041] As Figure 5 shown, the function of the arc-shaped guide plate 7 is to gently change its movement direction and convert the original linear movement into a movement along an arc. This process avoids the direct impact of the hub bearing on the turning groove 8, reducing the impact and possible damage. The turning groove 8 provides a clear movement path to constrain the hub bearing to roll along a specific arc. The second bottom plate 801 and the side plates form a groove to ensure that the hub bearing always remains on the predetermined track without deviation or tipping.

[0042] As Figure 5 shown, this design realizes the automatic adjustment of the attitude of the hub bearing without manual intervention. This is crucial on an automated production line, which can improve production efficiency and reduce labor costs.

[0043] As Figure 5As shown in the figure, a guiding path is formed inside the guiding groove along the rolling direction of the hub bearing. A number of flexible guiding sleeves 804 are evenly arranged on the inner side walls of the two second side plates 802 and along the guiding path. The flexible guiding sleeves 804 are made of silica gel, and a vibrating plate is arranged inside the inner cavity of the flexible guiding sleeve 804. The vibrating plate is used to generate intermittent and regular vibrations. One end of the vibrating plate is blocked inside the flexible guiding sleeve 804, and the other end of the vibrating plate is connected to the output end of a vibrating motor 805. The guiding groove defines a guiding path in the rolling direction, and the flexible guiding sleeves 804 provide additional flexible support and restraint. The flexible guiding sleeves 804 made of silica gel itself have a certain buffering and shock-absorbing effect. The vibrating motor 805 drives the vibrating plate to generate intermittent and regular vibrations. The vibrating plate is located in the inner cavity of the flexible guiding sleeve 804. Therefore, the vibrations will be transmitted to the guiding sleeve and then affect the rolling elements.

[0044] As Figure 5 shown, the regular vibrations will finely adjust the position of the hub bearing to avoid the hub bearing hitting the inner surface of the second side plate 802 when turning in the arc-shaped guiding groove, reduce wear, make them more evenly distributed on the guiding path, and improve the load-bearing capacity and service life.

[0045] As Figure 5 shown, the included angle between the vibrating plate and the second side plate 802 is 15 - 20°. After testing, it is found that this angle can more effectively transmit the vibration energy to the hub bearing to achieve the purposes of vibration reduction, lubrication improvement, or prevention of jamming.

[0046] Example 3, as Figure 6 shown, a guiding rail 9 is arranged on the rust prevention and passivation device 2. A discharge hole is arranged inside the guiding rail 9. An input groove 4 inclined downward is arranged between the discharge hole and the input end of the rust prevention and passivation device 2. The guiding end of the guiding groove faces the guiding rail 9. The guiding groove moves up and down inside the guiding rail 9, and a linear motor 10 for driving the guiding groove to move up and down is arranged between the guiding groove and the guiding rail 9. When the guiding groove moves upward through the linear motor 10 until the output end of the guiding groove coincides with the discharge hole, the hub bearing inside the guiding groove will be guided along the input groove 4 into the rust prevention and passivation device 2. This step-by-step feeding method can avoid problems such as blockage or inaccurate positioning caused by one-time feeding.

[0047] Example 4, a method for transporting the inner ring of a hub bearing across devices, based on the above-mentioned transporting device, the steps of transporting the hub bearing include: S1: The hub bearing polished and cleaned by the polishing and cleaning machine 1 will have its clamping component inside placed inside the trough body 303. At this time, the axial end face of the hub bearing fits the upper surface of the first bottom plate 301, and under the action of the inclination of the trough body 303, the hub bearing slides downward along the inner space of the trough body 303.

[0048] S2: By turning on the power supply of the driving motor, synchronous driving of a plurality of rotating shafts 503 is achieved, causing the eccentric rods 504 provided on the rotating shafts 503 to perform circular motion. A roller 505 is provided at one end of the eccentric rod 504, and the roller 505 fits the outer surface of the flexible peristaltic sleeve 502. By simulating the action of "throat swallowing", the flexible peristaltic sleeve 502 undergoes intermittent peristalsis, so that the flexible peristaltic sleeve 502 can generate frictional force on the hub bearing and slow down its sliding speed.

[0049] S3: Through the pressure exerted by the roller 505, a positive pressure is formed inside the main hose 601, ensuring that the lubricating oil can overcome the resistance and smoothly flow from the main hose 601 to the branch hoses 602; the branch hoses 602 are branched from the main hose 601, equivalent to multiple branches, dispersing the lubricating oil in the main hose 601 and providing a basis for uniform oil dripping; by imitating "throat saliva", while the flexible peristaltic sleeve 502 moves, the arc-shaped contact surface of the flexible peristaltic sleeve 502 can always obtain lubrication to avoid dry friction.

[0050] S4: The hub bearing coming out of the output trough 3 will slide down at a certain speed due to inertia or gravity. When the hub bearing falls into the guiding trough through the arc-shaped guiding plate 7 and is near the shoveling plate 803, the shoveling plate 803 extends under the drive of the electric telescopic rod to block the continuous sliding of the hub bearing. Due to the certain angle or arc of the shoveling plate 803, the sliding hub bearing is flipped by 90°, causing the radial surface of the hub bearing to roll inside the turning trough 8.

[0051] S5: When a certain number of hub bearings are arranged inside the guiding trough, the guiding trough moves upward through the linear motor 10 until the output end of the guiding trough coincides with the discharge hole. At this time, the hub bearings inside the guiding trough will be guided along the input trough 4 into the rust prevention and passivation device 2.

[0052] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
