Description

Technical Field

[0001] This application relates to the technical field of bearings, and in particular to a bearing and process that facilitates disassembly and assembly. Background Technology

[0002] A bearing is a mechanical component used to support rotating shafts and reduce their friction. It ensures the high-precision rotation of rotating bodies and withstands axial and radial loads, and is widely used in various mechanical equipment. Existing bearings typically consist of an inner ring, an outer ring, and rolling elements. The inner ring is usually keyed to the rotating shaft and rotates with the shaft, while the outer ring is connected to the bearing housing or a fixed part of the mechanical equipment, serving a supporting and positioning function.

[0003] In applications such as automotive transmission systems, machine tool spindles, and wind turbine generators, bearings and rotating shafts may require periodic disassembly and assembly for equipment inspection, maintenance, cleaning, replacement, or adjustment of components. However, the existing keyed connection between the rotating shaft and inner ring requires a side-knocking motion to disassemble the key from the keyway, making disassembly and assembly difficult. Furthermore, frequent disassembly and assembly of the rotating shaft leads to relative friction between the key and the keyway on the shaft, resulting in accelerated wear on both surfaces. As wear deepens, the clearance between the key and keyway increases, reducing the tightness and reliability of the keyed connection. This can cause loosening and slippage during transmission, affecting normal equipment operation. Therefore, further improvements are needed. Summary of the Invention

[0004] To improve the ease of disassembly and assembly between the bearing and the rotating shaft, this application provides a bearing and process for easy disassembly and assembly.

[0005] Firstly, the bearing that is easy to disassemble and assemble provided in this application adopts the following technical solution: A bearing that is easy to assemble and disassemble includes an inner ring, an outer ring, and a flange seat. Rolling elements are provided between the inner ring and the outer ring, and the flange seat is connected to the inner ring. The flange seat has an insertion channel for inserting a rotating shaft. The inner wall of the insertion channel has an installation groove, and a mating key is slidably installed in the installation groove. The outer peripheral wall of the rotating shaft has a mating keyway, and the flange seat is provided with a drive assembly for driving the mating key to be inserted into the mating keyway.

[0006] By adopting the above technical solution, in situations requiring periodic disassembly and assembly of the rotating shaft, during installation, the rotating shaft is inserted into the insertion channel, and the keyway of the rotating shaft is aligned with the mounting slot. Then, the drive assembly moves the key strip into the keyway, forcing the key strip against the inner wall of the keyway, thus connecting the rotating shaft and the bearing. During disassembly, the drive assembly moves the key strip into the mounting slot, disengaging it from the keyway of the rotating shaft, allowing for easy removal of the rotating shaft. This improves the ease of disassembly and assembly, reduces the possibility of structural damage caused by the key strip during disassembly and assembly, and extends the overall service life of the structure.

[0007] Optionally, the drive assembly includes a drive bar, a drive block, and a drive element. The drive bar is slidably installed in the mounting groove and connected to the mating key bar. The drive block is slidably installed in the mounting groove and two are spaced apart along the length of the drive bar. The drive element is used to drive the two drive blocks to move closer to each other or further away from each other. When the two drive blocks move closer to each other, the drive block forces the drive bar to slide towards the side closer to the mating key bar.

[0008] By adopting the above technical solution, after the rotating shaft is inserted into the mating channel, the driving component drives the two driving blocks to move closer to each other, causing the driving bar to slide towards the side closer to the mating key bar. This pushes the mating key bar and forces it into the mating keyway of the rotating shaft, improving overall operational convenience. Furthermore, by setting two driving blocks, the force on the driving bar is more evenly distributed, improving the clamping effect on the mating key bar.

[0009] Optionally, the sidewall of the drive bar away from the docking key bar has a guide surface, and the distance from the guide surface to the docking key bar gradually increases from both ends of the drive bar to the middle position of the drive bar. The drive block pushes the drive bar to slide through the guide surface.

[0010] By adopting the above technical solution, the distance from the guide surface to the mating key strip gradually increases from both ends of the drive strip to the middle position of the drive strip. This design allows the two drive blocks to press the drive strip together when they approach each other, so that the drive strip slides towards the side closer to the mating key strip.

[0011] Optionally, the driving component includes a driving rod rotatably mounted in the mounting groove, the driving rod being threaded through two driving blocks, and the threads of the driving rod and the two driving blocks being arranged in opposite directions.

[0012] By adopting the above technical solution, the threads of the drive rod and the two drive blocks are set in opposite directions, so that when the drive rod is rotated, the two drive blocks can move closer to each other or further away from each other, thereby improving the ease of operation of the overall structure.

[0013] Optionally, a first spring is provided between the drive bar and the docking key bar, and abutment bars are slidably installed on both sides of the docking key bar. A second spring is provided between the abutment bars and the docking key bar, and the second spring forces the abutment bars to abut against the docking key bar. A wedge-shaped bar is provided on the side wall of the drive bar near the docking key bar, and the wedge-shaped bar is used to insert between the abutment bars and the docking key bar.

[0014] By adopting the above technical solution, when the key bar is embedded in the keyway, the driving bar continues to slide towards the side closer to the key bar, causing the wedge-shaped strip of the driving bar to insert between the abutment strip and the key bar. This forces the two abutment strips to move away from each other, thus pressing against the two opposite sidewalls of the keyway to form a lock and restrict the axial displacement of the rotating shaft, improving the connection stability of the overall structure. When disassembling the rotating shaft, the driving bar is driven to slide away from the key bar, and the two abutment strips move closer to each other under the action of the second spring, thus disengaging from the sidewall of the keyway. This facilitates the removal of the key bar, improves the operational convenience of the overall structure, reduces frictional resistance during assembly and disassembly, and consequently reduces structural wear on the abutment strips.

[0015] Optionally, the two opposite sidewalls of the mating key strip are slidably fitted with diagonal braces. One end of the diagonal brace abuts against the abutting strip, and the other end passes into the mating key strip and out through the sidewall of the mating key strip near the driving strip, so that the driving strip can abut against it.

[0016] By adopting the above technical solution, when the drive bar drives the abutment bar to press against the side wall of the keyway through the wedge bar, the drive bar pushes the diagonal brace during this process, forcing the diagonal brace to press against the abutment bar, making the force on both sides of the abutment bar more uniform and improving the connection stability of the overall structure.

[0017] Optionally, the diagonal brace is provided with a first abutment surface and a second abutment surface at one end near the abutment bar. The first abutment surface is used to abut against the abutment bar, and the second abutment surface is used to abut against the bottom wall of the mating keyway.

[0018] By adopting the above technical solution, when the key bar abuts against the bottom wall of the keyway and the abutting bar abuts against the side wall of the keyway, the first abutting surface of the diagonal brace abuts against the abutting bar, and the second abutting surface abuts against the bottom wall of the keyway, increasing the contact area with the keyway, further restricting the displacement of the rotating shaft along its own axial direction, and improving the abutting effect on the abutting bar, thereby improving the stability of the overall structure.

[0019] Optionally, multiple diagonal braces are spaced apart along the length of the key bar, and the diagonal braces on the two opposite sidewalls of the key bar are arranged in a crisscross pattern within the key bar.

[0020] By adopting the above technical solution, multiple diagonal braces are arranged along the length of the key strip to increase the support points for the abutment strip, thereby improving the clamping effect on the abutment strip. The diagonal braces on the two opposite side walls of the key strip are arranged in a crisscross pattern within the key strip. The drive strip clamps the key strip and the abutment strip simultaneously through the diagonal braces, improving the overall structural connection stability.

[0021] Optionally, a locking block is slidably installed in the mounting groove, and a drive rod is threaded through the locking block; one end of the drive rod extends out of the mounting groove and is connected to a rotating head, the rotating head is connected to an anti-rotation strip, the anti-rotation strip has a first through hole, the side wall of the flange seat has a second through hole communicating with the mounting groove, the anti-rotation strip is connected to a locking bolt, the locking bolt passes through the first through hole and the second through hole in sequence and abuts against the locking block, and the locking bolt is threadedly connected to the inner wall of the second through hole.

[0022] By adopting the above technical solution, rotating the drive rod causes the two drive blocks to move closer to each other, forcing the mating key strip to press against the inner wall of the mating keyway. Then, the anti-rotation strip is installed on the rotating head, and the locking bolts are sequentially passed through the first and second through holes, so that the locking bolts press against the locking blocks, thereby locking the drive rod, restricting its free rotation, and eliminating the thread gap between the drive rods, keeping the mating key strip in a pressed state, and improving the stability of the overall structure.

[0023] Secondly, the bearing assembly process provided in this application adopts the following technical solution: A bearing assembly process specifically includes the following steps: S1, pretreatment: cleaning and checking parameters of each bearing component; S2, assembly: installing rolling elements between the inner and outer rings and performing sealing treatment; S3, debugging and inspection.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By configuring the drive assembly, in applications requiring periodic disassembly and assembly of the rotating shaft, during installation, the rotating shaft is inserted into the mating channel, aligning its keyway with the mounting slot. The drive assembly then moves the key bar into the keyway, forcing it against the inner wall of the keyway, thus connecting the rotating shaft and bearing. During disassembly, the drive assembly moves the key bar into the mounting slot, disengaging it from the keyway, allowing for easy removal of the rotating shaft. This improves the ease of assembly and disassembly, reduces the possibility of structural damage caused by the key bar during disassembly, and extends the overall lifespan of the structure. 2. By incorporating the abutment strip and wedge strip, when the key strip is embedded in the keyway, the driving strip continues to slide towards the side closest to the key strip, causing the wedge strip of the driving strip to insert between the abutment strip and the key strip. This forces the two abutment strips to move away from each other, thus pressing against the two opposite sidewalls of the keyway to form a lock and restrict the axial displacement of the rotating shaft, improving the overall structural stability. When disassembling the rotating shaft, the driving strip is driven to slide away from the key strip, and the two abutment strips move closer together under the action of the second spring, thus disengaging from the sidewall of the keyway. This facilitates the removal of the key strip, improves the operational convenience of the overall structure, reduces frictional resistance during assembly and disassembly, and consequently reduces structural wear on the abutment strips. 3. By setting the diagonal brace, when the key bar abuts against the bottom wall of the keyway and the abutting bar abuts against the side wall of the keyway, the first abutting surface of the diagonal brace abuts against the abutting bar, and the second abutting surface abuts against the bottom wall of the keyway, increasing the contact area with the keyway, further restricting the displacement of the rotating shaft along its own axial direction, and improving the abutting effect on the abutting bar, thereby improving the stability of the overall structure.

[0027] The following combination Figures 1-6 This application will be described in further detail. Example 1:

[0028] This application discloses a bearing that is easy to assemble and disassemble.

[0029] Reference Figure 1 A bearing designed for easy assembly and disassembly includes an inner ring 1, an outer ring 2, and a flange seat 3. The outer ring 2 is mounted on the outside of the inner ring 1, and the flange seat 3 is fixedly connected to the inner circumferential wall of the inner ring 1. A magnetically sealed assembly 12 and a lower sealing ring 13 are respectively installed between the inner ring 1 and the outer ring 2. Multiple sets of rolling elements 11 are installed between the magnetically sealed assembly 12 and the lower sealing ring 13 (the specific structures of the rolling elements 11, the magnetically sealed assembly 12, and the lower sealing ring 13 are existing technologies and will not be described in detail here). The inner ring 1 and the outer ring 2 are rotatably connected by the multiple sets of rolling elements 11.

[0030] Reference Figure 2 , Figure 3 The flange seat 3 has an insertion channel 31, which is coaxially arranged with the inner ring 1 for the insertion of the rotating shaft 6. The inner wall of the insertion channel 31 has a mounting groove 32, which extends axially along the rotating shaft 6 at both ends. A mating key 33 is slidably installed in the mounting groove 32. The outer peripheral wall of the rotating shaft 6 has a mating keyway 61 for the mating key 33 to be embedded in. The two ends of the mating keyway 61 extend axially along the rotating shaft 6.

[0031] The flange seat 3 is provided with a drive assembly 4 for driving the keyway bar 33 into the keyway groove 61. The drive assembly 4 includes a drive bar 41, a drive block 42, and a drive component. In this embodiment, the drive bar 41 is located in the mounting groove 32 and fixedly connected to the side wall of the keyway bar 33 away from the keyway groove 61. The drive block 42 is slidably installed in the mounting groove 32, and the drive block 42 is located on the side of the drive bar 41 away from the keyway bar 33. Two drive blocks 42 are spaced apart along the length of the drive bar 41.

[0032] The side wall of the drive bar 41 away from the mating key bar 33 has a guide surface 411. Both drive blocks 42 abut against the guide surface 411. The distance from the guide surface 411 to the mating key bar 33 gradually increases from both ends of the drive bar 41 towards the middle. When the two drive blocks 42 approach each other, the drive blocks 42 force the drive bar 41 to slide towards the side closer to the mating key bar 33 through the guide surface 411. The guide surface 411 has a guide bar 413. When the two drive blocks 42 move away from each other, the drive blocks 42 force the drive bar 41 to slide away from the mating key bar 33 through the guide bar 413.

[0033] A driving component is used to drive two driving blocks 42 to move closer or further apart. The driving component is a driving rod 43, which is rotatably mounted in the mounting groove 32. Both ends of the driving rod 43 extend along the length of the mating key strip 33. In this embodiment, the driving rod 43 passes through the two driving blocks 42, and the driving rod 43 is threadedly connected to the two driving blocks 42, with the threads of the driving rod 43 and the two driving blocks 42 having opposite directions. One end of the driving rod 43 protrudes from the mounting groove 32 and is fixedly connected to a rotating head 431. The rotating head 431 has a polygonal cross-sectional shape for use with tools such as wrenches.

[0034] The implementation principle of Embodiment 1 of this application is as follows: When installing the rotating shaft 6, insert the rotating shaft 6 into the insertion channel 31, rotate the drive rod 43, and force the two drive blocks 42 to move closer to each other. Under the action of the guide surface 411, the two drive blocks 42 together squeeze the drive bar 41, causing the mating key bar 33 to be embedded in the mating keyway 61 of the rotating shaft 6. During disassembly, simply rotate the drive rod 43 in the opposite direction, and the drive blocks 42, under the action of the guide bar 413, can force the mating key bar 33 to slide into the mounting groove 32, greatly improving the ease of disassembly and assembly of the rotating shaft 6. In addition, by setting two drive blocks 42, the force on the drive bar 41 is more balanced, improving the clamping effect on the mating key bar 33 within a limited space. Example 2:

[0035] This application discloses a bearing that is easy to assemble and disassemble.

[0036] The bearing disclosed in this application, which is easy to disassemble and assemble, differs from that in Embodiment 1 in that: Reference Figure 4 In this embodiment, a first spring 412 is provided between the docking key strip 33 and the driving strip 41. One end of the first spring 412 is fixedly connected to the docking key strip 33, and the other end is fixedly connected to the driving strip 41. The docking key strip 33 and the driving strip 41 are movably connected by the first spring 412. It should be noted that multiple first springs 412 are provided at intervals along the length direction of the docking key strip 33 (only one is shown in the figure), and the side wall of the docking key strip 33 near the driving strip 41 has a groove for mounting the first spring 412.

[0037] Both sides of the mating key 33 are slidably fitted with abutment strips 34. A second spring 341 is provided between each abutment strip 34 and the mating key 33. A guide rod 342 is fixedly connected to the side wall of the abutment strip 34 near the mating key 33. One end of the second spring 341 is fixedly connected to the mating key 33, and the other end is fixedly connected to the guide rod 342. Under normal conditions, the second spring 341 forces the abutment strip 34 to abut against the mating key 33. It should be noted that when the mating key 33 abuts against the two abutment strips 34, the distance between the opposite side walls of the two abutment strips 34 is less than the width of the mating keyway 61.

[0038] Two wedge-shaped bars 44 are fixedly connected to the side wall of the drive bar 41 near the mating key bar 33. Each wedge-shaped bar 44 is corresponding to one of the two abutment bars 34 and is inserted between the abutment bar 34 and the mating key bar 33. The side wall of the abutment bar 34 has a first chamfered surface 343, and the side wall of the wedge-shaped bar 44 has a second chamfered surface 441. When the drive bar 41 slides towards the side closer to the mating key bar 33, the wedge-shaped bar 44, through the cooperation of the first chamfered surface 343 and the second chamfered surface 441, inserts between the abutment bar 34 and the mating key bar 33, forcing the abutment bar 34 to slide away from the mating key bar 33.

[0039] The implementation principle of Embodiment 2 of this application is as follows: After the rotating shaft 6 is inserted into the insertion channel 31, it drives the driving bar 41 to slide towards the side closer to the mating key bar 33, so that the mating key bar 33 is embedded in the mating keyway 61. The driving bar 41 continues to slide towards the side closer to the mating key bar 33. At this time, the wedge-shaped bar 44 of the driving bar 41 is inserted between the abutment bar 34 and the mating key bar 33, forcing the two abutment bars 34 to move away from each other, thereby pressing against the two opposite sidewalls of the mating keyway 61 to form a lock, and restricting the axial displacement of the rotating shaft 6, thus improving the connection stability of the overall structure.

[0040] When disassembling the rotating shaft 6, the drive bar 41 is driven to slide away from the mating key bar 33. The two abutting bars 34 approach each other under the action of the second spring 341, thereby disengaging from the side wall of the mating keyway 61, so as to facilitate the removal of the mating key bar 33, improve the operational convenience of the overall structure and reduce frictional resistance during disassembly and assembly, thereby reducing the structural wear of the abutting bars 34. Example 3:

[0041] This application discloses a bearing that is easy to assemble and disassemble.

[0042] The difference between the bearing disclosed in this application embodiment, which is easy to disassemble and assemble, and Embodiment 2 is that: Reference Figure 5 In this embodiment, multiple diagonal braces 35 are provided on both opposite sidewalls of the key strip 33. These diagonal braces 35 are spaced apart along the length of the key strip 33. One end of each diagonal brace 35 abuts against the abutment bar 34, while the other end penetrates into the key strip 33 and exits from the sidewall of the key strip 33 near the drive bar 41, allowing the drive bar 41 to abut against it. The diagonal braces 35 on the two opposite sidewalls of the key strip 33 are arranged in a crisscross pattern within the key strip 33, and the key strip 33 has oblique holes 331 for the diagonal braces 35 to pass through. The guide rods 342 of the diagonal braces 35 and the abutment bar 34 are staggered along the length of the key strip 33.

[0043] The diagonal brace 35 is provided with a first abutting surface 351 and a second abutting surface 352 at one end near the abutting strip 34. The first abutting surface 351 is used to abut against the abutting strip 34, and the second abutting surface 352 is used to abut against the bottom wall of the mating keyway 61.

[0044] Reference Figure 6 In this embodiment, a locking block 36 is installed in the mounting groove 32, and the drive rod 43 passes through the locking block 36 and is threadedly connected to the locking block 36. The rotating head 431 of the drive rod 43 is connected to an anti-rotation strip 5, and an anti-rotation groove 53 is formed on the surface of the anti-rotation strip 5. The cross-sectional shape of the anti-rotation groove 53 is the same as the cross-sectional shape of the rotating head 431, and the anti-rotation strip 5 is sleeved on the rotating head 431 through the anti-rotation groove 53.

[0045] The surface of the anti-rotation strip 5 is provided with a first through hole 51, and the side wall of the flange seat 3 is provided with a second through hole 37 that connects to the mounting groove 32. The anti-rotation strip 5 is connected with a locking bolt 52. The locking bolt 52 passes through the first through hole 51 and the second through hole 37 in sequence and abuts against the locking block 36. The locking bolt 52 is threadedly connected to the inner wall of the second through hole 37.

[0046] The implementation principle of Embodiment 3 of this application is as follows: After the rotating shaft 6 is inserted into the insertion channel 31, it drives the driving bar 41 to slide towards the side closer to the mating key bar 33, thereby pushing the mating key bar 33 into the mating keyway 61. As the driving bar 41 moves, the driving bar 41 drives the two abutting bars 34 away from each other through the wedge bar 44, and pushes the diagonal brace 35 in this process, so that the diagonal brace 35 abuts the abutting bars 34, making the force on both sides of the abutting bars 34 more even and improving the connection stability of the overall structure.

[0047] By utilizing the first abutment surface 351 and the second abutment surface 352, when the mating key bar 33 abuts against the bottom wall of the mating keyway 61 and the abutment bar 34 abuts against the side wall of the mating keyway 61, the first abutment surface 351 of the diagonal brace 35 abuts against the abutment bar 34, and the second abutment surface 352 abuts against the bottom wall of the mating keyway 61, the contact area between the diagonal brace 35 and the mating keyway 61 is increased, further restricting the displacement of the rotating shaft 6 along its own axial direction, while improving the abutment effect on the abutment bar 34 and improving the overall structural stability.

[0048] This embodiment utilizes the design of the anti-rotation strip 5. When the drive rod 43 drives the two drive blocks 42 to approach each other, forcing the mating key strip 33 to press against the inner wall of the mating keyway 61, the anti-rotation strip 5 is installed on the rotating head 431, and the locking bolt 52 is sequentially passed through the first through hole 51 and the second through hole 37, so that the locking bolt 52 presses against the locking block 36, thereby locking the drive rod 43 and restricting its free rotation. At the same time, it also eliminates the thread gap between the drive rod 43 and the drive rod 43, keeping the mating key strip 33 in a pressed state and improving the stability of the overall structure. Example 4:
