Description

Technical Field

[0001] This application relates to the technical field of bearings, and more particularly to a quick-release bearing for rolling elements. Background Technology

[0002] Belt conveyors are widely used in tobacco processing production lines. They are mainly driven by a drive shaft that rotates the conveyor belt at high speed. Each end of the drive shaft is connected and supported by a set of bearings.

[0003] During equipment use, bearings need to be disassembled periodically for performance testing. The traditional method of bearing disassembly and inspection involves first removing connecting bolts, tapered pins and other connecting parts, then lifting and disassembling the outer ring of the bearing, and then inspecting and replacing internal components such as the cage and rolling elements. This process is quite complicated and cumbersome, and inspection and replacement are often carried out in this way, resulting in low efficiency in bearing inspection and assembly. Summary of the Invention

[0004] This application provides a quick-release bearing for rolling elements, which eliminates the need to remove all components such as connecting bolts, tapered pins, and bearing outer rings when disassembling or assembling rolling elements, thereby improving or solving the problem of low inspection and assembly efficiency of bearings.

[0005] This application provides a quick-release bearing for rolling elements, comprising: a bearing body, the bearing body including a bearing outer ring, the end face of the bearing outer ring having a disassembly groove, the disassembly groove communicating with the raceway where the rolling elements are located; a retaining cover is detachably fitted into the disassembly groove, the retaining cover being used to fill the disassembly groove.

[0006] By adopting the above technical solution, when it is necessary to periodically disassemble the bearing body for inspection and replacement of internal components such as the cage and rolling elements, the housing can be removed from the disassembly slot of the bearing outer ring. This exposes the rolling elements and cage located in the raceway. The rolling elements are then removed one by one for inspection and maintenance. The inspected or new rolling elements are then installed back into the raceway of the bearing body. Finally, the housing is reinstalled into the disassembly slot of the bearing outer ring to maintain the integrity of the bearing body. This process eliminates the need to remove all connecting bolts, taper pins, and the bearing outer ring, simplifying the inspection and replacement of internal components such as the cage and rolling elements, and improving the efficiency of bearing inspection and assembly.

[0007] In the above-mentioned optional technical solution for quick assembly and disassembly of rolling element bearings, the outer surface of the housing is flush with the end face and circumferential side face of the outer ring of the bearing.

[0008] By adopting the above technical solution, after the housing is installed into the disassembly groove of the bearing outer ring, the housing and the bearing body become a complete whole. The housing and the bearing body fit together perfectly, which does not affect the aesthetic appearance of the bearing body, nor does it affect the normal operation of the bearing body.

[0009] In the above-mentioned optional technical solution for quick assembly and disassembly of rolling element bearings, both sides of the housing are set as inclined surfaces along the circumferential direction of the outer ring of the bearing.

[0010] By adopting the above technical solution, since both sides of the housing are set as inclined surfaces, the inclined surfaces on both sides of the housing and the inclined surfaces of the disassembly groove on the outer ring of the bearing press against each other, including forming a dovetail groove assembly method, which directly increases the contact area between the housing and the outer ring of the bearing, and can further increase the stability of the housing installed on the bearing body.

[0011] In the above-mentioned optional technical solution for quick disassembly and assembly of rolling element bearings, a locking mechanism is provided inside the housing. The locking mechanism includes: a central gear, rotatably connected inside the housing; a first locking rack, slidably disposed inside the housing, the first locking rack meshing with the central gear; and a first locking groove corresponding to the first locking rack is formed on the inner wall of the disassembly groove of the bearing outer ring, the first locking rack being inserted into the first locking groove and engaging with the bearing outer ring.

[0012] By adopting the above technical solution, after the housing is installed into the disassembly groove of the bearing outer ring, the central gear on the housing is rotated. The central gear drives the first locking rack to insert into the first locking groove, thereby realizing the fixed connection between the housing and the bearing body, further increasing the connection strength between the housing and the bearing body, and further improving the stability of the bearing body during daily operation.

[0013] In the above-mentioned optional technical solution for quick-release bearings of rolling elements, the locking mechanism further includes a second locking rack slidably disposed within the housing, the second locking rack also meshing with the central gear; the outer ring of the bearing has a second locking groove corresponding to the second locking rack on the inner wall of the disassembly groove, the second locking rack being inserted into the second locking groove and engaging with the outer ring of the bearing; the central gear is located between the first locking rack and the second locking rack.

[0014] By adopting the above technical solution, since the central gear is located between the first locking rack and the second locking rack, when the central gear is rotated, the first locking rack and the second locking rack move in opposite directions. Therefore, the second locking rack and the first locking rack respectively fix the two sides of the housing to the outer ring of the bearing. The second locking rack and the first locking rack can work together to further stabilize and balance the housing and the bearing body, thereby further improving the stability of the bearing body in daily operation.

[0015] In the above-mentioned optional technical solution for quick-release bearings of rolling elements, the end face of the central gear facing the outside of the housing is provided with an exposed knob.

[0016] By adopting the above technical solution, the central gear can be rotated stably by the knob, which facilitates the disassembly and assembly of the entire housing assembly. Inserting external tools into the knob also makes it easy to rotate the central gear by the knob, thereby locking or unlocking the housing and the outer ring of the bearing.

[0017] In the above-mentioned optional technical solution for quick assembly and disassembly of bearings with rolling elements, a sliding groove is provided on the inner circumferential side of the housing, and two sets of corresponding telescopic clamping arms are provided in the sliding groove of the housing; the telescopic clamping arms include telescopic claws and support sleeves, the support sleeves are slidably connected to the housing, one end of the telescopic claws is inserted into the support sleeves and is in sliding damping cooperation with the support sleeves, and the two telescopic claws are used to jointly clamp the rolling elements in the raceway of the bearing body.

[0018] By adopting the above technical solution, the telescopic claw is pulled out from the support sleeve. By using two sets of telescopic clamping arms, the rolling elements located in the bearing body raceway can be clamped in sequence, realizing the multi-functionality of the cover. When the cover is located in the disassembly groove and the bearing body is running normally, the telescopic claw is pushed into the support sleeve, so that the telescopic clamping arms are in the retracted state. The telescopic clamping arms in the retracted state will not affect the normal operation of the rolling elements in the bearing body raceway.

[0019] In the above-mentioned optional technical solution for quick-release bearings of rolling elements, the support sleeve is provided with a vent hole.

[0020] By adopting the above technical solution, when the telescopic claw is pulled out of the support sleeve, the internal volume of the support sleeve increases. At this time, the support sleeve draws air in through the vent hole, which facilitates the smooth pulling out of the telescopic claw. When the telescopic claw is pushed into the support sleeve, the internal volume of the support sleeve decreases, and the air inside the support sleeve is squeezed out through the vent hole, which facilitates the smooth pushing of the telescopic claw into the support sleeve.

[0021] In the above-mentioned optional technical solution for quick-release bearings of rolling elements, the cover is connected to a spring on the inner wall of the slide groove, and the other end of the spring is connected to the support sleeve.

[0022] By adopting the above technical solution, the spring design enables two sets of telescopic clamping arms to stably clamp rolling bodies of different specifications.

[0023] In the above-mentioned optional technical solution for quick disassembly and assembly of rolling element bearings, an open-type guide rail is provided inside the housing, and a guide part is provided at the end of the support sleeve opposite to the telescopic claw. The guide part is located inside the open-type guide rail and slides in cooperation with the open-type guide rail.

[0024] By adopting the above technical solution, the open-type guide rail slides and guides the guide part, thereby achieving smooth guidance of the telescopic clamping arm. The open-type guide rail also provides stable support for the telescopic clamping arm through the sliding part, so that the two sets of telescopic clamping arms can slide smoothly in the enclosure and stably clamp the rolling body.

[0025] The rolling element quick-release bearing provided in this application has a disassembly groove on the end face of the bearing outer ring. A retaining cover is detachably mounted within the groove. The retaining cover contains a locking mechanism for locking the retaining cover to the bearing outer ring. Two sets of corresponding telescopic clamping arms are also located within the retaining cover, used to grip the rolling elements within the bearing raceway. When the bearing body needs to be periodically disassembled for inspection or replacement of internal components such as the cage and rolling elements, the locking mechanism is unlocked, the retaining cover is disconnected from the bearing outer ring, and the two sets of corresponding telescopic clamping arms are used to sequentially remove the rolling elements from the raceway. The removed rolling elements are then inspected and maintained. The inspected or new rolling elements are then sequentially installed back into the bearing raceway using the two sets of corresponding telescopic clamping arms. Finally, the locking mechanism is locked to maintain the integrity of the bearing body. This process eliminates the need to remove all connecting bolts, taper pins, and the bearing outer ring, simplifying the inspection and replacement of internal components such as the cage and rolling elements, and improving the efficiency of bearing inspection and assembly.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] As described in the background section, belt conveyors are widely used in tobacco processing production lines. They are mainly driven by a drive shaft that rotates the conveyor belt at high speed. Each end of the drive shaft is connected and supported by a set of bearings.

[0043] During equipment use, bearings need to be disassembled periodically for performance testing. The traditional method of bearing disassembly and inspection involves first removing connecting bolts, tapered pins and other connecting parts, then lifting and disassembling the outer ring of the bearing, and then inspecting and replacing internal components such as the cage and rolling elements. This process is quite complicated and cumbersome, and inspection and replacement are often carried out in this way, resulting in low efficiency in bearing inspection and assembly.

[0044] To address the aforementioned technical problems, this application provides a quick-release bearing for rolling elements. A disassembly groove is provided on the end face of the bearing outer ring. A retaining cover is detachably mounted within the groove. The retaining cover contains a locking mechanism for locking the retaining cover to the bearing outer ring. Two sets of corresponding telescopic clamping arms are also provided within the retaining cover, used to jointly grip the rolling elements within the bearing raceway. When it is necessary to periodically disassemble the bearing body for inspection or replacement of internal components such as the cage and rolling elements, the locking mechanism is unlocked, the retaining cover is disconnected from the bearing outer ring, and the two sets of corresponding telescopic clamping arms are used to sequentially remove the rolling elements from the raceway. The removed rolling elements are inspected and maintained, and then the two sets of corresponding telescopic clamping arms are used to sequentially install the inspected or new rolling elements back into the bearing raceway. Finally, the locking mechanism is locked to maintain the integrity of the bearing body. The above process eliminates the need to remove all components such as connecting bolts, tapered pins, and bearing outer rings, simplifying the inspection and replacement of internal components such as cages and rolling elements, and improving the efficiency of bearing inspection and assembly.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The following will be combined with the appendix... Figure 1-4 The embodiments of this application will be described below.

[0046] Figure 1 This is a three-dimensional structural diagram of the rolling element quick-release bearing provided in an embodiment of this application. Figure 2 This is a partial structural diagram of the rolling element quick-release bearing after the cover has been removed, as provided in an embodiment of this application. Figure 3 This is a schematic diagram of the cover and its auxiliary mechanism on the quick-release bearing for rolling elements provided in an embodiment of this application. Figure 4 This is a cross-sectional view of the housing on a quick-release bearing for rolling elements provided in an embodiment of this application.

[0047] Please refer to Figure 1 and Figure 2 This application provides a quick-release bearing for a rolling element 120, comprising: a bearing body 100, the bearing body 100 including a bearing outer ring 110, and a disassembly groove 111 formed on the end face of the bearing outer ring 110, the disassembly groove 111 communicating with the raceway where the rolling element 120 is located, and the disassembly groove 111 extending to the inner circumference of the bearing outer ring 110. A retaining cover 200 is detachably fitted into the disassembly groove 111, the retaining cover 200 being used to fill the disassembly groove 111.

[0048] Specifically, when it is necessary to periodically disassemble the bearing body 100 to inspect and replace internal components such as the cage and rolling elements 120, the housing 200 is removed from the disassembly slot 111 of the bearing outer ring 110. This exposes the rolling elements 120 and the cage located in the raceway. The rolling elements 120 are then removed one by one for inspection and maintenance. The inspected or new rolling elements 120 are then installed back into the raceway of the bearing body 100. Finally, the housing 200 is reinstalled into the disassembly slot 111 of the bearing outer ring 110 to maintain the integrity of the bearing body 100. This process eliminates the need to completely remove connecting bolts, taper pins, the bearing outer ring 110, and other components, simplifying the inspection and replacement of internal components such as the cage and rolling elements 120, and improving the efficiency of bearing inspection and assembly.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments provided in this application, for example, the outer surface of the housing 200 is flush with the end face and peripheral side face of the bearing outer ring 110. Specifically, after the housing 200 is installed into the disassembly groove 111 of the bearing outer ring 110, the housing 200 and the bearing body 100 become a complete unit, and the housing 200 and the bearing body 100 fit together perfectly, which does not affect the aesthetic appearance of the bearing body 100, nor does it affect the normal operation of the bearing body 100.

[0050] Please refer to Figure 2 and Figure 3 In some embodiments provided in this application, for example, both sides of the housing 200 are set as inclined surfaces along the circumferential direction of the bearing outer ring 110. This includes at least the following situations: First, the two sides of the housing 200 are arranged parallel to each other. Second, the inclination directions of the two sides of the housing 200 are inconsistent, that is, the extended surfaces of the two sides of the housing 200 intersect in the space outside the housing 200, including two situations: First, viewed from the inner circumference of the housing 200, the housing 200 appears to be a trapezoidal shape, that is, the disassembly groove 111 is open; second, viewed from the inner circumference of the housing 200, the housing 200 appears to be an inverted trapezoidal shape, that is, the disassembly groove 111 is constricted.

[0051] Specifically, since both sides of the housing 200 are set as inclined surfaces, the inclined surfaces on both sides of the housing 200 and the inclined surfaces of the disassembly groove 111 on the outer ring 110 of the bearing press against each other, including forming a dovetail groove type assembly method, which directly increases the contact area between the housing 200 and the outer ring 110 of the bearing, and can further increase the stability of the housing 200 installed on the bearing body 100.

[0052] Please refer to Figure 3 and Figure 4In some embodiments provided in this application, for example, a locking mechanism is provided inside the housing 200. The locking mechanism includes: a central gear 300, rotatably connected to the center inside the housing 200; a first locking rack 400, slidably disposed inside the housing 200, the first locking rack 400 meshing with the central gear 300; and a first locking groove corresponding to the first locking rack 400 formed on the inner wall of the disassembly groove 111 of the bearing outer ring 110. The first locking rack 400 is inserted into the first... The locking groove is inserted into the bearing outer ring 110; the second locking rack 500 is slidably disposed in the housing 200, and the second locking rack 500 also meshes with the central gear 300. The bearing outer ring 110 has a second locking groove corresponding to the second locking rack 500 on the inner wall of the disassembly groove 111. The second locking rack 500 is inserted into the second locking groove and inserted into the bearing outer ring 110. The central gear 300 is located between the first locking rack 400 and the second locking rack 500.

[0053] Specifically, after installing the housing 200 into the disassembly / removal slot 111 of the bearing outer ring 110, the central gear 300 on the housing 200 is rotated. Since the central gear 300 is located between the first locking rack 400 and the second locking rack 500, the first locking rack 400 and the second locking rack 500 move in opposite directions. The central gear 300 drives the first locking rack 400 to insert into the first locking groove, and the central gear 300 drives the second locking rack 500 to insert into the second locking groove. The second locking rack 500 and the first locking rack 400 respectively fix the two sides of the housing 200 to the bearing outer ring 110. When it is necessary to remove the housing 200, the central gear 300 is rotated in the opposite direction. The central gear 300 simultaneously drives the first locking rack 400 and the second locking rack 500 to retract into the housing 200, quickly releasing the connection between the housing 200 and the bearing outer ring 110.

[0054] Please refer to Figure 3 and Figure 4 In some embodiments provided in this application, for example, the end face of the central gear 300 facing the outside of the housing 200 is integrally formed with an exposed knob 310. Specifically, the knob 310 facilitates stable rotation of the central gear 300, making it convenient for disassembly and assembly of the entire housing 200 assembly; inserting external tools into the knob 310 also facilitates rotation of the central gear 300 via the knob 310, enabling mutual locking or unlocking of the housing 200 and the bearing outer ring 110.

[0055] Please refer to Figure 3 and Figure 4In some embodiments provided in this application, for example, a groove 210 is provided on the inner circumferential side of the cover 200, and two sets of corresponding telescopic clamping arms 600 are slidably connected in the groove 210. The telescopic clamping arm 600 includes a telescopic claw 610 and a support sleeve 620. The support sleeve 620 is slidably connected to the cover 200, and the support sleeve 620 is provided with a vent hole 621. One end of the telescopic claw 610 is inserted into the support sleeve 620 and is in sliding damping cooperation with the support sleeve 620. The free ends of the two telescopic claws 610 are used to jointly clamp the rolling element 120 in the raceway of the bearing body 100.

[0056] Specifically, by pulling the telescopic claw 610 out from the support sleeve 620, and using two sets of telescopic clamping arms 600, the rolling elements 120 located in the raceway of the bearing body 100 can be clamped in sequence, thus realizing the multi-functionality of the cover 200; when the cover 200 is located in the disassembly groove 111 and the bearing body 100 is operating normally, the telescopic claw 610 is pushed into the support sleeve 620, so that the telescopic clamping arms 600 are in a retracted state. The retracted telescopic clamping arms 600 will not affect the normal operation of the rolling elements 120 in the raceway of the bearing body 100.

[0057] When the telescopic claw 610 is pulled out of the support sleeve 620, the volume inside the support sleeve 620 increases. At this time, the support sleeve 620 draws air in through the vent hole 621, which facilitates the smooth pulling out of the telescopic claw 610. When the telescopic claw 610 is pushed into the support sleeve 620, the volume inside the support sleeve 620 decreases, and the air inside the support sleeve 620 is squeezed out through the vent hole 621, which facilitates the smooth pushing of the telescopic claw 610 into the support sleeve 620.

[0058] Please refer to Figure 3 and Figure 4 In some embodiments provided in this application, for example, a spring 700 is fixedly connected to the inner wall of the slide groove 210 of the cover 200, and the other end of the spring 700 is fixedly connected to the support sleeve 620. Specifically, the spring 700 applies pressure to the rolling element 120 through the telescopic clamping arm 600. The design of the spring 700 enables the two sets of telescopic clamping arms 600 to stably clamp rolling elements 120 of different specifications.

[0059] Please refer to Figure 4 In some embodiments provided in this application, for example, an open-type guide rail 800 is fixedly connected inside the cover 200. The direction of the open-type guide rail 800 is parallel to the sliding direction of the telescopic clamping arm 600. A disc-shaped guide part 622 is integrally formed at one end of the support sleeve 620 away from the telescopic claw 610. The guide part 622 is located inside the open-type guide rail 800 and slides with the open-type guide rail 800.

[0060] Specifically, the open-type guide rail 800 slides to guide the guide part 622, thereby achieving smooth guidance of the telescopic clamping arm 600. The open-type guide rail 800 also provides stable support for the telescopic clamping arm 600 through the sliding part, so that the two sets of telescopic clamping arms 600 can slide smoothly in the cover 200 and stably clamp the rolling body 120.

[0061] In summary, when it is necessary to periodically disassemble the bearing body 100 and inspect or replace internal components such as the cage and rolling elements 120, the center gear 300 is rotated. The center gear 300 simultaneously drives the first locking rack 400 and the second locking rack 500 to retract into the housing 200, quickly disengaging the housing 200 from the bearing outer ring 110. Two sets of corresponding telescopic clamping arms 600 are then used to sequentially remove the rolling elements 120 from the raceway. The removed rolling elements 120 are then inspected and maintained. Finally, two sets of corresponding telescopic clamping arms 600 are used... The telescopic clamping arm 600 sequentially installs the repaired rolling element 120 or the new rolling element 120 back into the raceway of the bearing body 100. Finally, the central gear 300 on the housing 200 is rotated, and the central gear 300 drives the first locking rack 400 to insert into the first locking groove. The central gear 300 drives the second locking rack 500 to insert into the second locking groove. The second locking rack 500 and the first locking rack 400 respectively fix the two sides of the housing 200 to the outer ring 110 of the bearing to maintain the integrity of the bearing body 100.

[0062] The above process eliminates the need to remove all components such as connecting bolts, tapered pins, and bearing outer ring 110, simplifying the inspection and replacement of internal components such as cage and rolling elements 120, and improving the efficiency of bearing inspection and assembly.
