Description

Technical Field

[0001] This invention relates to a self-lubricating bearing, and more specifically to a combined overheat-resistant self-lubricating bearing assembly. Background Technology

[0002] Self-lubricating dustproof bearing housings are bearing assemblies that integrate self-lubrication and dustproof design, suitable for harsh working environments. Through a built-in self-lubricating system and a sealed dustproof structure, the self-lubricating system automatically lubricates the bearing, while the dustproof structure effectively prevents external dust and impurities from entering. It is a key component for friction reduction and protection in modern industrial machinery. This bearing housing significantly reduces maintenance frequency, extends bearing life, and ensures the continuity and reliability of equipment operation.

[0003] Existing technologies suffer from the following drawbacks, resulting in poor lubrication: Bearing housings have numerous friction surfaces, primarily located between the inner ring and shaft, the outer ring and housing, and the rollers (or balls, sprockets) and inner / outer rings. Self-lubricating bearing housings rely on lubricant in the oil sac to gradually penetrate the friction surfaces via capillary action or pressure difference, providing continuous lubrication. However, unlike externally added lubricant, the flow rate of the lubricant is smaller, and its release is slower, failing to reach all friction surfaces promptly. Therefore, a reasonable lubrication path needs to be established to ensure the lubricant reaches each lubrication point evenly and smoothly. Furthermore, additional lubricant distribution points should be added inside the bearing housing to ensure uniform coverage of all surfaces requiring lubrication, thereby improving the overall operational quality and reliability of the equipment. Additionally, the bearing structure is simple and its function is singular, lacking a dedicated heat dissipation device. During operation, the bearing is prone to failure due to insufficient heat dissipation, reducing the service life of both the bearing and the housing.

[0004] In view of this, the present invention designs a combined overheat-resistant self-lubricating bearing assembly. Summary of the Invention

[0005] The main objective of this disclosure is to provide a combined overheat-resistant self-lubricating bearing assembly to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A combined overheat-resistant self-lubricating bearing assembly includes a bearing body and a bearing mounting base. Cross brackets are fixedly installed on both sides of the lower end of the bearing mounting base, and the cross brackets are integrally formed. The two cross brackets are arranged one in front of the other. The bearing body is movably installed between the two cross brackets. An axial mounting shaft is installed between the two cross brackets, and the axial mounting shaft passes through the center of the bearing body. The bearing mounting base has an internal lubricating oil storage chamber, and a supplementary pipe extending to the outside of the bearing mounting base is installed on the rear side of the lubricating oil storage chamber. A self-delivery drip nozzle is installed through the bottom of the bearing mounting base, and a liquid passage is opened inside the self-delivery drip nozzle. An external bearing connector is fixedly installed on the outer shell of the bearing body, and an oil passage leading to the inside of the bearing body is opened on the external bearing connector. The lower port of the liquid passage faces the upper port of the oil passage, and the upper end of the self-delivery drip nozzle is located inside the lubricating oil storage chamber. The bearing mounting base is equipped with a drive mechanism that moves the self-feeding pipe drip head. A lifting rod is fixedly connected to the bottom of the bearing mounting base, and a controller is fixedly installed at the bottom end of the lifting rod. The controller works in conjunction with the drive mechanism. Both sides of the bearing mounting base are inlaid with magnetic docking blocks, and a cavity is opened inside the bearing mounting base, in which a spiral cooling pipe is fixedly installed.

[0007] Preferably, the surface of the self-feeding pipe dropper is provided with a self-leaking hole, and the self-leaking hole is located inside the lubricating oil storage chamber.

[0008] Preferably, the driving mechanism includes a hydraulic rod support, a small hydraulic push rod, a sealing gasket, a sliding sleeve plate, and a return spring. The hydraulic rod support is fixedly installed on the top of the bearing mounting seat. The small hydraulic push rod is fixedly installed on the hydraulic rod support, and the output end of the small hydraulic push rod extends into the lubricating oil storage chamber and is fixedly connected to the sealing gasket. The self-feeding tube dripper is fixedly connected to the bottom of the sealing gasket. A sliding sleeve plate is slidably installed on the outer surface of the self-feeding tube dripper, and a return spring is fixedly connected between the sliding sleeve plate and the sealing gasket. The return spring is sleeved on the self-feeding tube dripper.

[0009] Preferably, the size of the sliding sleeve is larger than the size of the spontaneous leakage hole, and the sliding sleeve covers the spontaneous leakage hole.

[0010] Preferably, the controller has a groove on its side, and a power supply board is fixedly connected in the groove. A pressure sensor is fixedly installed on the power supply board, and both the small hydraulic push rod and the pressure sensor are electrically connected to an external computer.

[0011] Preferably, the controller also has a movable groove on its side, and a telescopic contact is slidably installed in the movable groove. One end of the telescopic contact extends out of the movable groove and is fixedly connected to a pressing plate. The size of the pressing plate is larger than the size of the movable groove, and a compression spring is fixedly connected between the pressing plate and the movable groove. The compression spring is sleeved on the telescopic contact.

[0012] Preferably, a finger pressure rod is slidably installed in the groove, with one end of the finger pressure rod facing the pressure sensor, and the moving direction of the telescopic contact is opposite to the moving direction of the finger pressure rod.

[0013] Preferably, a steering shaft is rotatably mounted inside the controller, and a conversion gear is fixedly mounted on the steering shaft. A second rack is fixedly connected to the finger pressure rod, and a first rack is fixedly connected to the pressing plate. The first rack and the second rack are uniformly engaged by the conversion gear for transmission.

[0014] Preferably, a permanent magnet ball is fixedly installed on the outer side of the bearing outer joint, and the permanent magnet ball and the pressing plate are magnetically repelled.

[0015] In view of this, compared with the prior art, the beneficial effects of the present invention are: (I) In this application, the bearing mounting base can be installed on the working lathe, enabling the application of self-lubricating bearings. The bearing body is installed between two cross supports, protecting it from external interference and reducing power consumption. If the bearing body lacks lubricating oil, the small hydraulic push rod is activated, causing the sealing gasket to move downward in the lubricating oil storage chamber. This causes the self-delivery pipe dropper to move downward, with its lower end aligning with the bearing's external connector, connecting the hydraulic and oil circuits. The sliding sleeve plate then moves downward, blocking the lower end of the lubricating oil storage chamber. This compresses the return spring, exposing the self-draining hole, allowing the lubricating oil in the storage chamber to enter the self-delivery pipe dropper through the self-draining hole, and then enter the bearing body through the hydraulic and oil circuits, thus achieving the purpose of adding lubricating oil and ensuring its long-term smooth operation.

[0016] (II) In this application, if the bearing body becomes dull during rotation, the rotation speed will be affected, and the movement speed of the bearing external joint and the permanent magnet ball will decrease. The magnetic induction between the permanent magnet ball and the pressing plate will change accordingly. That is, when the permanent magnet ball slowly approaches the pressing plate, under the action of its magnetic repulsion, the telescopic contact slides into the movable groove, the compression spring is compressed, the first rack drives the conversion gear to rotate, and the second rack drives the finger pressure rod to slide in the groove until the finger pressure rod contacts the pressure sensor. The pressure sensor transmits the detected pressure signal to the peripheral computer, and the peripheral computer controls the small hydraulic push rod to work automatically, thereby completing the automatic delivery of lubricating oil and avoiding the drawbacks of inaccuracy caused by human monitoring.

[0017] (iii) In this application, the magnetic mating blocks on both sides of the bearing mounting base are used to assemble adjacent bearing bodies, so that the self-lubricating bearings can be combined, thereby facilitating layout and application. The spiral cooling pipe inside the bearing mounting base can be activated when the temperature is high and reduce the temperature during use, maintaining a relatively good operating condition and achieving the purpose of preventing overheating.

[0022] Specifically, the surface of the self-feeding pipe dripper 6 is provided with a self-leaking hole 11, which is located inside the lubricating oil storage chamber 5. The driving mechanism includes a hydraulic rod support 8, a small hydraulic push rod 9, a sealing gasket 10, a sliding sleeve plate 12, and a return spring 13.

The self-feeding pipe dripper 6 is fixedly connected to the bottom of the sealing gasket 10. The sliding sleeve plate 12 is slidably installed on the outer surface of the self-feeding pipe dripper 6, and a return spring 13 is fixedly connected between the sliding sleeve plate 12 and the sealing gasket 10. The return spring 13 is sleeved on the self-feeding pipe dripper 6. The size of the sliding sleeve plate 12 is larger than the size of the self-leaking hole 11, and the sliding sleeve plate 12 covers the self-leaking hole 11.

[0023] Specifically, the controller 15 has a groove on its side, and a power board 16 is fixedly connected in the groove. A pressure sensor 17 is fixedly installed on the power board 16.

The bearing body 1 is installed between two cross brackets 3 to protect it and prevent interference from external factors. The power consumption is low. If the bearing body 1 lacks lubricating oil, the small hydraulic push rod 9 is opened, which drives the sealing gasket 10 to move downward in the lubricating oil storage chamber 5. Then the self-delivery pipe dropper 6 moves downward and its lower end is connected to the bearing external connector 7, so that the liquid passage and oil passage are connected.

Then the self-draining hole 11 will be exposed, so that the lubricating oil in the lubricating oil storage chamber 5 enters the self-delivery pipe dropper 6 through the self-draining hole 11, and then enters the bearing body 1 through the liquid passage and oil passage, thereby achieving the purpose of adding lubricating oil and ensuring its long-term smooth operation. If the bearing body 1 becomes dull during rotation, the rotation speed will be affected, and the moving speed of the bearing outer connector 7 and the permanent magnet ball 25 will decrease. The magnetic induction of the permanent magnet ball 25 and the pressing plate 19 will change accordingly. That is, when the permanent magnet ball 25 slowly approaches the pressing plate 19, under the action of its magnetic repulsion, the telescopic contact 18 slides into the movable groove, the compression spring 20 is compressed, the first rack 21 drives the conversion gear 23 to rotate, and the second rack 24 drives the finger pressure rod to slide in the groove until the finger pressure rod contacts the pressure sensor 17. The pressure sensor 17 transmits the detected pressure signal to the peripheral computer. The peripheral computer controls the small hydraulic push rod 9 to work automatically, thereby completing the automatic delivery of lubricating oil and avoiding the drawbacks of inaccuracy caused by human monitoring. The magnetic mating blocks 26 on both sides of the bearing mounting base 2 are used to assemble adjacent bearing bodies 1, such as... Figure 8As shown, the self-lubricating bearings can be combined, which facilitates layout and application. The spiral cooling pipe 27 in the bearing mounting base 2 can be activated when the temperature is high and reduce the temperature during use, maintaining a better operating condition and achieving the purpose of preventing overheating.
