Description

Technical Field

[0001] This invention belongs to the field of bearing technology, specifically a novel assembled spherical bearing. Background Technology

[0002] Assembled spherical roller bearings are standardized bearing units composed of spherical roller bearings and prefabricated bearing housings. They feature good self-aligning performance, convenient installation and disassembly, and can be quickly deployed in assembly. They are widely used in various industrial transmission scenarios such as mining machinery, agricultural machinery, conveying machinery, fans, and textile machinery, playing an important role in rotary transmission systems.

[0003] In the existing technology, assembled spherical roller bearings have the following drawbacks: Firstly, existing mounted spherical roller bearings lack early warning capabilities regarding lubrication status. Lubrication maintenance relies entirely on manual periodic oiling, making it impossible to identify early problems such as hardening or thickening of the lubricating oil. By the time abnormal noises and high temperatures are detected on-site, the internal lubricating oil has already carbonized and clumped, and the bearing raceway and cage have suffered irreversible wear. The entire machine must be disassembled for cleaning and maintenance, or even scrapped and replaced. This not only results in high maintenance costs but also leads to long downtime for equipment equipped with mounted spherical roller bearings (hereinafter referred to as "equipment"), making preventative maintenance impossible.

[0004] Secondly, the existing bearing oil filling structure is usually a single oil filling port design, which makes it very easy for lubricating oil to flow out of proportion during oil filling. Often, oil overflows from one side of the seal ring while a large amount of old lubricating oil remains on the other side of the raceway, making it impossible to replace the old and new lubricating oil in the entire area. At the same time, if the old lubricating oil blocks the oil passage during the oil filling process, it can easily cause a sudden increase in internal pressure, directly pushing open the bearing seal ring and causing it to be damaged, resulting in seal failure. After external dust and moisture enter, they will further accelerate the deterioration of lubricating oil and bearing corrosion, forming a vicious cycle of failure.

[0005] Thirdly, regarding the problem of hardened lubricating oil, existing technologies typically use handheld hot air guns and heating coils for external heating, which requires carrying specialized tools and suffers from problems such as inaccurate heating positions and difficulty in temperature control. This can easily damage the rubber sealing rings on both sides, and uneven heating can lead to insufficient softening of the old lubricating oil inside, resulting in poor non-disassembly maintenance performance. This technology is completely unsuitable for the efficient and standardized non-disassembly maintenance needs of industrial sites. Summary of the Invention

[0006] The purpose of this invention is to address the deficiencies mentioned in the background technology by proposing a novel assembled spherical bearing that enables early and accurate warning of bearing lubrication status, precise heating and softening of old lubricating oil without disassembly, uniform oil injection and replacement with 360° no dead angle, and automatic protection against oil injection overpressure. This reduces the difficulty of bearing maintenance, extends the service life of the bearing, and avoids downtime losses caused by disassembly and maintenance from the root.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: The present invention provides a novel assembled spherical bearing, comprising a bearing housing, a bearing body, a bearing seal ring, and a folded heating and maintenance assembly disposed on the side wall of the bearing housing; The bearing housing is provided with an oil injection and drainage assembly on its side wall. The oil injection and drainage assembly includes a plurality of oil injection ports arranged in a ring. The inner cavity of the bearing housing is provided with a lubricating oil channel communicating with the oil injection ports. The bottom end of the bearing housing is provided with an oil drain port. A foldable heating maintenance assembly includes self-locking slots and self-locking heating slots on both sides of the bearing seat, and the inner cavity of each self-locking slot is hinged with a foldable heating mechanism. The bearing seal ring is provided with a pressure relief protection component, which includes an auxiliary pressure relief lip; the inner cavity of the bearing housing is provided with a high temperature warning component.

[0008] Preferably, one end of each of the plurality of oil inlets is threaded with a steel sealing cap, the plurality of oil inlets are connected through a lubricating oil channel, and an oil drain plug is threaded into the inner cavity of the oil drain port, with a sealing rubber ring fitted on the oil drain plug.

[0009] Preferably, the self-locking slot and the self-locking heating slot are interconnected, the length of the self-locking slot is shorter than that of the self-locking heating slot, and the self-locking slot and the self-locking heating slot are arranged in opposite directions in an arc shape; the inner cavity of the self-locking slot is provided with an insertion groove, and a protective insert plate is slidably inserted into the insertion groove; the inner cavity of the self-locking heating slot is provided with a rubber dustproof ring, and the inner bottom wall of the self-locking heating slot is provided with an L-shaped heat-conducting copper strip that fits against the outer wall of the bearing body.

[0010] Preferably, the foldable heating mechanism includes a plurality of interlocking arc-shaped heating strips, and the arc shape of the arc-shaped heating strips matches the arc shape of the self-locking slot and the self-locking heating groove. One end of the arc-shaped heating strip is provided with a steering component, and the outer side wall of the steering component is provided with a vertical anti-slip groove. The other end of the steering component is hinged to the connection between the self-locking slot and the self-locking heating groove.

[0011] Preferably, the arc-shaped heating strip is connected to a power supply slot via a wire, and the power supply slot is located on the side wall of the bearing seat.

[0012] Preferably, the auxiliary pressure relief lip is protruding and connected to the bearing seal ring, and the inner cavity of the auxiliary pressure relief lip is provided with multiple mutually fitted and inclined one-way rubber guide plates.

[0013] Preferably, the high temperature warning component includes a temperature sensing module and a warning light. The temperature sensing module includes a bearing-specific annular temperature probe arranged in a ring shape close to the outer ring of the bearing body. The warning light is electrically connected to the annular temperature probe.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through its built-in high-temperature early warning component and the use of a ring-shaped temperature probe closely attached to the outer ring of the bearing body, can comprehensively and in real time monitor the abnormal temperature rise of the bearing caused by early hardening and thickening failure of the lubricating oil in 360°, triggering early warning reminders in advance. It guides maintenance during critical periods when the bearing experiences irreversible wear and lubricating oil carbonization and agglomeration, transforming traditional passive fault repair into proactive preventive maintenance, and avoiding bearing failure due to lubricating oil carbonization and agglomeration.

[0015] 2. This invention, through a folding heating and maintenance component integrated with the bearing housing, combined with a self-locking heating groove precisely corresponding to the outer ring of the bearing body and an L-shaped heat-conducting copper strip, can achieve precise directional heating after shutdown. The heat is quickly and evenly transferred to the lubrication area of ​​the bearing raceway and cage, fully softening the hardened old lubricating oil. At the same time, the heating area avoids the bearing seals on both sides, preventing aging and deformation of the seals. No additional heating tools are required, making it suitable for on-site maintenance without disassembly and reducing the difficulty of maintenance operations.

[0016] 3. This invention achieves 360° uniform oil injection through multiple annularly arranged oil injection ports and a fully interconnected lubricating oil channel. Combined with the oil drain port at the bottom of the bearing housing, it can squeeze out softened old lubricating oil and internal impurities, leaving no dead corners. At the same time, the bearing seal ring has an auxiliary pressure relief lip and a one-way rubber guide plate. During the oil injection process, when the internal pressure exceeds the safety threshold, it can automatically slightly expand to relieve pressure and automatically reset after the pressure recovers. This solves the defect of traditional oil injection that easily damages the seal ring and ensures the sealing and protection performance of the bearing.

[0017] 4. The oil injection and drainage components, folding heating and maintenance components, pressure relief and protection components, and high temperature warning components of this invention are all integrated into the bearing housing and bearing body. They do not change the installation dimensions, center height, and interchangeability of the standard assembled external bearing body. They can directly replace the existing general-purpose UCP, UCF, UCT and other series of mounted external bearing bodies without modifying the original installation structure of the equipment. They have strong adaptability and take into account the convenience of assembled installation and the practicality of maintenance without disassembly.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] like Figures 1-10As shown, a novel assembled spherical bearing includes a bearing housing 1, a bearing body 2, a bearing seal ring 3, and a foldable heating and maintenance assembly 5 disposed on the side wall of the bearing housing 1. The side wall of the bearing housing 1 is provided with an oil injection and drainage assembly 4, which includes multiple oil injection ports 41 arranged in a ring. The inner cavity of the bearing housing 1 is provided with a lubricating oil channel 42 communicating with the oil injection ports 41, and the bottom end of the bearing housing 1 is provided with an oil drain port 43. The foldable heating and maintenance assembly 5 includes self-locking slots 51 and self-locking heating grooves 52 opened on both sides of the bearing housing 1. The inner cavity of each self-locking slot 51 is hinged with a foldable heating mechanism 53. The bearing seal ring 3 is provided with a pressure relief protection assembly 6, which includes an auxiliary pressure relief lip 61. The inner cavity of the bearing housing 1 is provided with a high-temperature warning assembly 7.

[0024] By integrating the oil injection and drainage component 4, the folding heating and maintenance component 5, the pressure relief and protection component 6, and the high temperature warning component 7 into the bearing housing 1 and the bearing body 2, a maintenance-free closed loop is formed. The bearing lubrication status can be monitored and maintained without external monitoring and maintenance equipment. This avoids the problems of cumbersome maintenance and poor adaptability caused by the independent functional structures of traditional bearings, simplifies the overall bearing structure, improves the stability of bearing operation and the convenience of maintenance, and extends the service life of the bearing.

[0025] One end of each of the multiple oil filling ports 41 is threaded with a steel sealing cap 44. The multiple oil filling ports 41 are connected through a lubricating oil channel 42. The inner cavity of the oil drain port 43 is threaded with an oil drain plug 45, and a sealing rubber ring 46 is fitted on the oil drain plug 45. The oil filling ports 41 and the oil drain plug 45 with the sealing rubber ring 46 achieve sealing protection. The annularly arranged oil filling ports 41 are connected through the lubricating oil channel 42 to achieve 360° uniform oil filling, preventing dust and moisture from entering the oil circuit and bearing interior during daily operation, thereby preventing lubricating oil leakage and contamination. At the same time, it achieves seamless replacement of old and new lubricating oil, solving the problems of uneven oil filling and old lubricating oil residue in the traditional single oil filling port 41, and improving the maintenance effect of oil filling.

[0026] The self-locking slot 51 and the self-locking heating slot 52 are interconnected. The length of the self-locking slot 51 is shorter than that of the self-locking heating slot 52, and the self-locking slot 51 and the self-locking heating slot 52 are arranged in opposite directions in an arc shape. The inner cavity of the self-locking slot 51 has an insertion slot 54, and a protective insert plate 55 is slidably inserted into the insertion slot 54. The inner cavity of the self-locking heating slot 52 is provided with a rubber dustproof ring 56, and the inner bottom wall of the self-locking heating slot 52 is provided with an L-shaped heat-conducting copper strip 57 that fits against the outer wall of the bearing body 2. The arc-shaped groove matches the outer ring curvature of the bearing body 2 to achieve precise heating positioning. The L-shaped heat-conducting copper strip 57 improves the heat conduction efficiency. The protective insert 55 and the rubber dustproof ring 56 provide dust protection for the groove and the heating structure, allowing the heating area to avoid the bearing seal ring 3, preventing high temperature from burning the seal. At the same time, it accelerates the heat conduction to the inside of the bearing, quickly softens the hardened lubricating oil, and prevents dust and moisture from entering the groove and affecting the heating effect, protecting the foldable heating mechanism 53 from damage.

[0027] The foldable heating mechanism 53 includes multiple interconnected arc-shaped heating strips 531, the arc shape of which matches the arc shape of the self-locking slot 51 and the self-locking heating groove 52. One end of the arc-shaped heating strip 531 is provided with a steering component 532, and the outer side wall of the steering component 532 is provided with a vertical anti-slip groove. The other end of the steering component 532 is hinged to the connection between the self-locking slot 51 and the self-locking heating groove 52. The folding and unfolding of the multi-segmented arc-shaped heating strips 531 are achieved. The steering component 532, in conjunction with the anti-slip groove, enables the heating mechanism to be flexibly flipped. In the non-maintenance state, the heating mechanism can be stored in the self-locking slot 51 without interfering with the normal operation of the bearing. During maintenance, it can be quickly unfolded and tightly fitted with the self-locking heating groove 52. The anti-slip groove provides an anti-slip function when gripped, meeting the needs of quick and non-disassembly maintenance on site.

[0028] The arc-shaped heating strip 531 is connected to a power supply slot 58 via a wire. The power supply slot 58 is located on the side wall of the bearing housing 1. The power supply slot 58 provides a convenient power supply interface for the arc-shaped heating strip 531, enabling quick connection between the heating mechanism and the power supply, simplifying the power supply operation of the heating mechanism, eliminating the need for complicated wiring procedures, improving maintenance efficiency, and integrating the power supply structure into the bearing housing 1 to ensure the overall compactness and aesthetics of the bearing.

[0029] The auxiliary pressure relief lip 61 is protruding and connected to the bearing seal ring 3. The inner cavity of the auxiliary pressure relief lip 61 is provided with multiple mutually fitted and inclined one-way rubber guide plates 62. The one-way rubber guide plates 62 form an automatically opening and closing pressure relief structure. When the pressure is over-pressurized, the lubricating oil pushes open the guide plates and is discharged. After the pressure is restored, the guide plates close and reset. This solves the problem of oil circuit blockage during the oil injection process causing a sudden increase in internal pressure that damages the bearing seal ring 3. It realizes automatic pressure relief for over-pressure, and the normal sealing and protection performance of the bearing is not affected after pressure relief, avoiding the leakage of lubricating oil and the intrusion of impurities due to seal failure.

[0030] The high-temperature warning component 7 includes a temperature sensing module 71 and a warning light 72. The temperature sensing module 71 includes a bearing-specific annular temperature probe 711 that is arranged in a ring shape close to the outer ring of the bearing body 2. The warning light 72 is electrically connected to the annular temperature probe 711. The annular temperature probe 711 is close to the outer ring of the bearing to achieve real-time temperature monitoring. When the temperature is abnormal, the warning light 72 is triggered to alarm, accurately detecting the abnormal temperature rise of the bearing caused by the early hardening of the lubricating oil. The warning is issued before the bearing experiences irreversible wear, reserving maintenance time for maintenance without disassembly, and transforming traditional passive fault repair into proactive preventive maintenance to avoid bearing failure.

[0031] Working principle: I. Daily Operation and Temperature Anomaly Early Warning Phase Under the stable operating conditions of normal rated speed and rated load, the working temperature of the bearing body 2 remains within a stable range and there will be no abnormal high temperature. When the lubricating oil inside the bearing body 2 experiences early hardening and thickening failure, it will lead to increased internal friction of the bearing. During normal operation, the bearing body 2 will experience an abnormal temperature rise. At this time, the ring temperature probe 711 will detect the abnormal temperature change of the bearing and then transmit the abnormal signal to the warning light 72 through the signal conversion terminal of the temperature sensing module 71 and the high-temperature resistant connecting wire. The warning light 72 will continuously flash red warning light to remind on-site personnel to stop the machine in time for non-disassembly maintenance. This early warning stage can accurately monitor early signs of lubricating oil hardening. It triggers a reminder before irreversible wear occurs in the bearing body 2 and before the lubricating oil carbonizes and clumps, leaving ample room for subsequent maintenance without disassembly.

[0032] II. Shutdown Preparation and Heating / Softening Stage Upon receiving the warning, the staff first shut down the equipment and disconnected the main power supply, locked the equipment's operating status, located the bearing body 2 corresponding to the warning, and carried out pre-maintenance preparation and heating operations: First, remove the protective insert plate 55 inside the self-locking slot 51 and the insertion slot 54 to release the protection of the foldable heating mechanism 53; Push the steering component 532 to rotate the interlocking arc-shaped heating strip 531 about the hinge center of the steering component 532, and move it out of the inner cavity of the self-locking slot 51. Then, fully unfold the folded arc-shaped heating strip 531 and push it into the self-locking heating groove 52 that is connected to the self-locking slot 51, so that the heating surface of the arc-shaped heating strip 531 is tightly attached to the inner bottom wall of the self-locking heating groove 52. At this time, the positioning self-locking buckle in the self-locking heating groove 52 will lock and fix the arc-shaped heating strip 531 to prevent displacement or loosening during the heating process. Connect the matching wire of the arc heating strip 531 to the power supply slot 58 on the side wall of the bearing seat 1. The anti-drop self-locking buckle in the power supply slot 58 automatically locks the wire connector to prevent the wire from coming loose during the heating process. Then connect the power supply circuit to start the arc heating strip 531. During the heating process, because the opening position of the self-locking heating groove 52 corresponds perfectly to the axial position of the stationary outer ring of the bearing body 2, and with the precise heat conduction of the L-shaped heat-conducting copper strip 57, the heating area is limited to the bearing lubrication area of ​​the outer ring of the bearing body 2, avoiding the bearing seals 3 on both sides. This prevents the bearing seals 3 from being deformed by high temperature, resulting in a loose seal. The heat generated by the arc-shaped heating strip 531 is quickly and accurately conducted to the outer ring of the bearing body 2 through the metal bearing seat 1, and then penetrates into the lubrication area of ​​the bearing raceway and cage, fully softening the hardened lubricating oil inside. At the same time, the temperature control module of the heating system will stably control the heating temperature within a safe range of 65-70℃, which can fully restore the fluidity of the hardened old lubricating oil without causing the lubricating oil to carbonize or the bearing seals 3 to age and be damaged, thus making full preparations for the subsequent replacement of old and new lubricating oil.

[0033] III. Oil filling without disassembly and replacement of old and new lubricating oil stage After heating and maintaining a constant temperature for 20-30 minutes, the old lubricating oil inside the bearing body 2 will be completely softened. First, unscrew the oil drain plug 45 with sealing rubber ring 46 inside the oil drain port 43 at the bottom of the bearing housing 1 to open the oil drain channel. Then, unscrew the steel sealing caps 44 of the multiple oil filling ports 41 on the side wall of the bearing housing 1 one by one, and add lubricating oil to the multiple oil filling ports 41 in a ring. After the new lubricating oil is injected, it will enter the raceway and cage area of ​​the bearing body 2 evenly in 360° through the lubricating oil channel 42 that is interconnected in the inner cavity of the bearing housing 1. The softened old lubricating oil and internal impurities closest to the oil injection port 41 will be squeezed out along the inner cavity of the bearing towards the bottom oil drain port 43. When clean new lubricating oil is observed to flow out steadily from the oil drain port 43, it indicates that the old lubricating oil inside the bearing body 2 has been completely replaced, and the oil injection can be stopped. During the oil filling process, to avoid the problem of insufficiently softened old lubricating oil partially blocking the lubricating oil channel 42, causing a sudden increase in internal pressure of the bearing body 2 and opening the main sealing port of the bearing seal ring 3, this invention is equipped with a safety pressure relief mechanism: when the pressure inside the bearing body 2 and the lubricating oil channel 42 is higher than the preset safety threshold (0.08-0.12MPa), the excess lubricating oil will push open the auxiliary pressure relief lip 61 on the bearing seal ring 3, pushing the one-way rubber guide plate 62 of the main sealing structure to open slightly, safely discharging the overpressure lubricating oil; after the internal pressure returns to the normal range, the one-way rubber guide plate 62 and the auxiliary pressure relief lip 61 will automatically reset, without affecting the sealing performance of the main sealing structure throughout the process, thus preventing damage and failure of the bearing seal ring 3; All of the above operations are performed in the early stage when the lubricating oil has just hardened. The lubricating oil can be completely replaced without disassembly, avoiding failures such as complete carbonization of the lubricating oil, wear and jamming of the bearing body 2, and the need to disassemble the entire machine to clean and replace the bearing. This extends the service life of the bearing body 2, reduces the downtime maintenance cost of the equipment and the difficulty of manual operation, and realizes preventive maintenance of the bearing without disassembly.

[0034] IV. Maintenance Completion and Structural Repositioning and Storage Phase First, confirm that the replacement of old and new lubricating oil inside the bearing body 2 is complete. Then, screw the oil drain plug 45 with the sealing ring 46 back into the oil drain port 43 at the bottom of the bearing housing 1 and tighten it to ensure that the oil drain port 43 is tightly sealed. Then, tighten the steel sealing caps 44 of all oil filling ports 41 one by one to prevent external dust and moisture from entering the lubricating oil passage 42 and the interior of the bearing body 2, and restore the bearing's sealing and protective structure. Disconnect the heating power supply circuit, unlock the anti-drop self-locking buckle of the power supply slot 58, and pull out the connecting wire of the arc heating strip 531; then release the positioning self-locking buckle of the arc heating strip 531 in the self-locking heating groove 52, push the steering component 532 in the opposite direction, and drive the interlocked arc heating strip 531 out of the self-locking heating groove 52. Fold and store the arc heating strip 531 in the reverse order of unfolding, and insert it into the inner cavity of the self-locking slot 51. Finally, push the protective insert 55 back into the insertion slot 54 of the self-locking slot 51 to close and lock the protective insert 55, providing full protection for the foldable heating mechanism 53 after it is stored. The entire maintenance process is now complete, and the equipment can be restarted for normal operation.

[0035] Furthermore, the latches mentioned in this article, such as the latches in the self-locking slot 51, the anti-drop self-locking latches in the electrical slot, and the positioning self-locking latches in the self-locking heating slot 52, are all common spring latches, not shown in the text, and belong to the prior art, so they will not be described in detail here.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
