Description

Technical Field

[0001] This application belongs to the field of bearing replacement technology, specifically relating to a bearing housing disassembly and fixing device. Background Technology

[0002] Rolls are mechanical equipment that operates continuously in production. After the rolls come off the machine, the bearing housings need to be inspected and repaired. The inspection includes checking for wear, cracks, deformation, and wear or loosening of the locating pins and holes. If any abnormalities are found, they need to be repaired or replaced to ensure the rolls can be used normally on the machine. During the roll maintenance process, the bearings need to be disassembled and installed.

[0003] During bearing assembly and disassembly, due to the height difference between the bearing housing end faces, wooden blocks are needed to keep it level. The bearing housing is transported using slings, and the operator adjusts its height and level remotely. Laying the wooden blocks during this process greatly increases the risk of hand injuries from crushing or falling objects. Over time, the wooden blocks become covered in oil and grease, and the bearing housing can easily slip on them, posing a risk of it falling and injuring someone. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] This utility model discloses a bearing housing disassembly and fixing device, which can solve the technical problem of easy slippage in the prior art, thereby improving the safety and efficiency of the bearing housing disassembly and assembly process.

[0030] The technical solution of this application will be described in detail below through specific embodiments:

[0031] See Figure 1 and Figure 2 This application discloses a bearing housing assembly and disassembly device, which includes a base 100, a first fixing plate 200, a movable plate 300, and a ball bearing 400. The base 100 has a bottom plate groove 110 and multiple limiting grooves 120. The bottom plate groove 110 is located at the middle of the width direction of the base 100, and each limiting groove 120 is located on both sides of the bottom plate groove 110, with each limiting groove 120 on each side spaced apart along the length direction of the base 100. The first fixing plate 200 is installed at one end of the length direction of the base 100. The movable plate 300 slides along the length direction of the base 100. Each limiting groove 120 contains a ball bearing 400, and the opening of the limiting groove 120 is smaller than the diameter of the ball bearing 400 so that the ball bearing 400 can rotate within the limiting groove 120.

[0032] The bearing housing assembly and fixing device disclosed in this embodiment replaces the wooden blocks with a fixing device, effectively avoiding the risk of hand crushing and crushing injuries, as well as the risk of the bearing housing slipping and hitting people. Operators do not need to directly contact the bottom of the bearing housing, completely avoiding the risk of hand injury caused by the movement of wooden blocks or the slipping of the bearing housing.

[0033] The ball bearing 400 rotates freely within the limiting groove 120, allowing the bearing housing to move smoothly during assembly and disassembly, significantly reducing frictional resistance. Compared to the traditional method of using wooden blocks as a support, operators do not need to exert extra force to push the bearing housing, greatly improving assembly and disassembly efficiency.

[0034] In one embodiment, the bearing housing disassembly and fixing device further includes a second fixing plate 500. The second fixing plate 500 is disposed at the other end of the base 100 along its length, and is disposed opposite to the first fixing plate 200. The movable plate 300 is slidably engaged with the second fixing plate 500.

[0035] The first fixed plate 200 and the second fixed plate 500 are respectively disposed at both ends of the base 100 along its length, forming a stable support structure. This design allows the movable plate 300 to receive more even and stable support during sliding, effectively preventing tilting or swaying caused by unilateral support.

[0036] The movable plate 300 not only slides with the base 100, but also slides with the second fixed plate 500. This double-end sliding engagement design makes the movable plate 300 slide more smoothly and steadily, reducing the jamming or displacement that may occur due to a single-sided sliding engagement.

[0037] In one embodiment, the bearing housing disassembly and fixing device further includes a slide rod 600. The slide rod 600 is arranged along the length direction of the base 100, and the slide rod 600 is slidably engaged with the second fixing plate 500, and the movable plate 300 is connected to the slide rod 600.

[0038] The sliding engagement between the slide rod 600 and the second fixed plate 500, combined with the original sliding structure of the movable plate 300, forms a dual-guide support system. This design allows the movable plate 300 to receive dual support from both the slide rod 600 and the base 100 as it moves along the length of the base 100, significantly reducing swaying and offset, and ensuring that the bearing seat remains stable during assembly and disassembly.

[0039] The rigid structure of the slide bar 600 provides a precise guide path for the moving plate 300, allowing operators to control the movement of the bearing housing more accurately and significantly improving assembly and disassembly precision. The guiding role of the slide bar 600 is particularly crucial when fine-tuning the bearing housing position is required.

[0040] In one embodiment, there are three or more slide rods 600, each slide rod 600 is slidably connected to the second fixed plate 500, and each slide rod 600 is connected to the movable plate 300.

[0041] The layout of three or more slide bars 600 makes the moving plate 300 more evenly stressed, effectively dispersing the gravity and impact force generated by the bearing housing during disassembly and assembly, avoiding stress concentration problems that may occur with single or double slide bars 600, and significantly improving the overall stability of the device.

[0042] In one embodiment, the bearing housing disassembly and fixing device further includes a threaded rod 700, which is threadedly connected to the second fixing plate 500 and rotatably connected to the movable plate 300.

[0043] The threaded rod 700 converts the rotational motion into the linear motion of the moving plate 300 through thread transmission. By utilizing the self-locking characteristic of the thread, precise displacement control of the bearing housing can be achieved, with the error range controllable within the micrometer level, meeting the disassembly and assembly requirements of high-precision bearing housings.

[0044] The self-locking feature of the threaded rod 700 automatically locks the position of the moving plate 300 after it stops rotating, preventing the bearing housing from shifting due to external force or vibration, and ensuring the stability of the bearing housing during disassembly and assembly.

[0045] In one embodiment, the second fixing plate 500 is provided with a threaded hole 510 and a through hole 520, with the threaded hole 510 and the through hole 520 spaced apart. The threaded rod 700 is threadedly connected to the threaded hole 510, and the sliding rod 600 is slidably engaged with the through hole 520.

[0046] The threaded connection between the threaded hole 510 and the threaded rod 700 forms a rigid support point, which effectively resists the lateral and longitudinal eccentric loads generated during the disassembly and assembly of the bearing housing, and prevents the device from deforming due to uneven force.

[0047] The sliding fit between the through hole 520 and the slide bar 600 provides flexible guidance for the moving plate 300, reducing jamming caused by machining errors or vibration, while dispersing lateral forces and protecting the threaded connection structure.

[0048] In one embodiment, a rotating disk 310 is provided on the side of the threaded rod 700 away from the moving plate 300.

[0049] The rotating disk 310 has a larger diameter than the threaded rod 700, forming a force-saving lever and reducing the physical exertion required for the operator to rotate the threaded rod 700. Similar to the design of a car steering wheel, the increased rotation radius reduces the operating torque and improves comfort.

[0050] In one embodiment, each side of the limiting groove 120 is provided with at least three columns, and the limiting grooves 120 of adjacent columns are staggered along the width direction of the base 100.

[0051] The misalignment limiting groove 120 forms a "stepped" support structure. Through the synergistic effect of multiple rows of limiting grooves 120, the bearing housing is restricted from offset in the width and length directions, thereby improving installation accuracy.

[0052] In one embodiment, a plurality of base plate grooves 110 are provided, and the plurality of base plate grooves 110 are spaced apart along the length direction of the base 100.

[0053] Multiple base plate slots 110 allow for flexible selection of fixing positions to accommodate bearing housings of different sizes. For example, small bearing housings can be fixed using a single base plate slot 110; medium-sized bearing housings can be fixed across two base plate slots 110; and large bearing housings can be fixed using three or more base plate slots 110 simultaneously.

[0054] In one embodiment, the cross-section of the limiting groove 120 is hemispherical, and the height of the limiting groove 120 is greater than the radius of the ball 400.

[0055] The hemispherical limiting groove 120 fits perfectly with the spherical surface of the ball 400, forming point contact or line contact, ensuring that the ball 400 is stably positioned within the limiting groove 120 and preventing it from shifting or falling off.

[0056] The curved surface design of the hemispherical limiting groove 120 can evenly distribute the load borne by the ball 400 to the wall of the limiting groove 120, avoiding deformation or damage caused by local stress concentration.

[0057] In one embodiment, a connecting block 320 is provided on the side of the movable plate 300 facing the second fixed plate 500, and the threaded rod 700 is rotatably connected to the connecting block 320.

[0058] The connecting block 320 serves as the rotation fulcrum of the threaded rod 700, bearing the axial and radial forces transmitted by the threaded rod 700 and preventing deformation or damage to the threaded rod 700. The fixed connection between the connecting block 320 and the moving plate 300 ensures that the moving plate 300 moves along a straight trajectory, preventing deviation or jamming.

[0059] In one embodiment, the bearing housing disassembly and fixing device further includes two side plates 800, which are located on both sides of the base 100 and are lower than the movable plate 300. Due to the obstruction effect of the side plates 800, the bearing will not deviate from the preset trajectory during the advancement process, and the bearing housing can be prevented from accidentally tipping over during disassembly and assembly, avoiding damage to operators or equipment.

[0060] The side plate 800 can serve as a lateral reference datum during bearing housing installation, assisting operators in quickly aligning the bearing housing with the shaft system and improving installation accuracy.

[0061] The design of the side plate 800 being lower than the movable plate 300 ensures that when operators are disassembling or assembling bearing seats below the movable plate 300, the movable plate 300 or tools will not interfere with the side plate 800, providing ample vertical operating space.

[0062] In one embodiment, lifting lugs 900 are provided on the top of both the first fixing plate 200 and the second fixing plate 500.

[0063] The bearing housing assembly and fixing device can be moved via the lifting lug 900, which is not limited by power supply or site conditions and does not occupy the fixed area of ​​the bearing maintenance area, making it convenient for on-site hoisting of rollers, inner rings, etc.

[0064] Through the above embodiments, this application has the following beneficial effects or advantages: The bearing housing disassembly and fixing device disclosed in this application replaces the wooden blocks used for padding, effectively avoiding the risks of hand injuries from being squeezed or crushed, as well as the risk of the bearing housing slipping and hitting people. The ball bearing 400 design allows the bearing housing to move smoothly during disassembly and assembly, reducing friction and improving disassembly and assembly efficiency. The multi-row limiting groove 120 and slide bar 600 design enhance the stability and load-bearing capacity of the device, ensuring the safety of the bearing housing during disassembly and assembly. The rotating disk 310 design makes the operation of the threaded rod 700 more convenient and improves work efficiency.

[0065] The bearing housing disassembly and fixing device disclosed in this application can eliminate the height difference of bearing housings, ensuring that the bearing does not tilt. It can also disassemble and install bearings on different bearing housings, without requiring specific bearing models, significantly improving work efficiency and ensuring operator safety.
