Description

Technical Field

[0001] This invention relates to the field of bearing box disassembly technology, specifically to an integrated bearing box bearing lateral disassembly device and a bearing box bearing lateral disassembly method. Background Technology

[0002] During C6 overhaul (comprehensive disassembly and overhaul) of the electric locomotive drive system, the axle box structure is a critical component. To ensure the quality of the electric locomotive, all bearings within the drive system must be replaced. In practice, there is a set of bearings at each end of the axle box, so these bearings must be disassembled and replaced during disassembly. Furthermore, because the bearings and axle box are interference-fitted, hydraulic tools are required for disassembly.

[0003] The current solution uses a bearing box disassembly fixture that requires assembling various components, making the operation complex. The disassembly process requires two people working simultaneously and occupies the overhead crane for extended periods, resulting in low efficiency. More importantly, the disassembly fixture requires manual adjustment multiple times during the preparation and disassembly phases. Specifically, operators must manually hold the hydraulic jacks while adjusting the fixture; improper adjustment can damage components or endanger personnel safety.

[0004] Therefore, it is urgent to improve the existing bearing disassembly fixtures to achieve semi-automatic disassembly of bearings while ensuring disassembly quality, thereby improving disassembly efficiency and reducing overhead crane occupancy. Summary of the Invention

[0005] The purpose of this invention is to provide a solution to the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An integrated bearing housing lateral disassembly device includes: The disassembly mechanism includes a base plate and at least two pull blocks evenly distributed radially along the base plate; the pull blocks are used to hold and engage with the inner ring end face of the bearing housing; a limit pin is fixedly provided on the end face of the base plate, and a guide groove is provided on the pull block, the limit pin and the guide groove forming a sliding pair; a support block is fixedly provided at the center of the end face of the base plate, one end of the pull block is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the support block; Telescopic device, used to control the radial movement of the pulling block along the base plate; Hydraulic mechanism, including hydraulic cylinder and hydraulic pump that drives the hydraulic cylinder to move; A tie rod, one end of which is fixedly connected to the top of the support block, and the other end of which is fixed to the outside of the hydraulic cylinder; The support mechanism includes a baffle and at least two push rods. One end of the push rod is fixed to the end face of the baffle, and the other end of the push rod is used to contact the outer end face of the bearing box. The other end face of the baffle away from the push rod is fixedly connected to the hydraulic cylinder. A tie rod is installed through the baffle, the hydraulic cylinder and the hydraulic pump.

[0007] The above technical solution produces the following technical effects: First, the device described in this application does not require prolonged overhead crane operation during disassembly. In the specific disassembly process, the bearing of the bearing box can be disassembled simply by placing the bearing box horizontally in the disassembly area using the disassembly device. Second, the bearing box disassembly device of this application is a single-piece structure, unlike existing devices which use multiple disassembly components, disassembly parts, and fixing parts. In the specific disassembly process, the device of this application first uses a puller block in the disassembly mechanism to hold and engage the inner ring end face of the bearing box, then uses a push rod in the support mechanism to abut the outer end of the bearing box, and a hydraulic mechanism drives a pull rod to move the puller block in the disassembly mechanism to disassemble the bearing box. This eliminates the need to fix each disassembly component, disassembly part, and fixing part as required by existing devices, improving disassembly accuracy and reducing errors caused by adjustments to individual components. Furthermore, the device of this application does not require multiple operators. Existing bearing box disassembly devices require adjustment, positioning, and support during the assembly of each component; this application only requires personnel to install the disassembly device and operate it directly.

[0008] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the telescopic device includes a linkage mechanism and a telescopic sleeve; The linkage mechanism has one end fixedly connected to the pull block and the other end hinged to the outer periphery of the pull rod; The telescopic sleeve is fitted around the outer periphery of the pull rod and positioned between the linkage mechanism and the baffle. When the telescopic sleeve is subjected to force and slides, it acts on the linkage mechanism, which in turn drives the pulling block to move toward the support block.

[0009] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the pull block has a stepped structure, including a high platform and a low platform. The high platform has a guide groove, and the low platform is used to form an axial clamping fit with the inner ring end face of the bearing housing.

[0010] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the limiting pin includes a smooth rod section and a pin cap. The smooth rod section passes through the guide groove, and one end of the smooth rod section is fixedly connected to the base plate, while the other end is fixedly connected to the pin cap.

[0011] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the linkage mechanism includes a first link and a second link. One end of the first link is fixedly connected to a platform, the other end of the first link is hinged to one end of the second link, and the other end of the second link is hinged to a lug provided on the outer periphery of the pull rod.

[0012] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the linkage mechanism also includes a third link for hinged connection of the first link and the second link. One end of the third link is hinged to one end of the first link via a connecting pin, and the other end of the third link is hinged to one end of the second link via a connecting pin.

[0013] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the end of the pull rod away from the support block has a threaded structure, which is used to install the gasket and nut that prevent the hydraulic pump from moving in sequence.

[0014] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the support block is polygonal, and the number of its sides is the same as the number of the pull-out blocks.

[0015] As a further improvement to the lateral disassembly device for an integrated bearing housing of this application, the base plate is a circular plate with a diameter smaller than the diameter of the inner hole of the bearing housing.

[0016] In addition, this application also designs a method for lateral disassembly of a bearing housing, including the following steps: Step S1: Place the cleaned axle box horizontally in the axle box bearing disassembly area, and adjust any of the above-mentioned integrated axle box bearing horizontal disassembly devices to the center height of the axle box's circular hole, so that the center of the base plate is aligned with the center of the axle box's circular hole. Step S2: Move the telescopic sleeve towards the base plate. The telescopic sleeve drives the linkage mechanism to retract the pulling block towards the support block until the disassembly mechanism can enter the inner hole of the bearing box. Step S3: Adjust the movable telescopic sleeve to the initial position so that the pull block is used to hold and engage with the inner ring end face of the bearing of the bearing box. Start the hydraulic pump to move the hydraulic cylinder toward the disassembly mechanism side. The hydraulic cylinder drives the support mechanism to move toward the outer end face of the bearing box until the push rod in the support mechanism abuts against the outer end face of the bearing box. Step S4: Keep the hydraulic cylinder moving toward the disassembly mechanism side, and the pull rod will drive the disassembly mechanism to move away from the bearing box until the bearing box bearing is separated from the bearing box, and then turn off the hydraulic pump; Step S5: Move the integrated bearing lateral disassembly device to the other side of the bearing box and repeat steps S1-S4 to disassemble the bearing box on the other side of the bearing box.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0019] It is worth noting that, referring to Figure 1 As shown, before disassembling the existing bearing housing 7, the cleaned bearing housing 100 needs to be transferred to the bearing housing disassembly area using the existing bearing housing disassembly fixture. An overhead crane is then used to lift the bearing housing 100 from the fixture onto the disassembly workbench and place it upright. The specific details of the upright placement of the bearing housing 100 on the disassembly workbench are as follows: Figure 2 As shown. (Refer to...) Figure 3 As shown, the existing bearing housing disassembly fixture includes a disassembly device 1' and a hydraulic device 2', wherein the disassembly device 1' includes a disassembly disc 11' and a connecting piece 12'. The connecting piece 12' includes a connecting rod 121' and a connecting block 122' fixed to one side of the connecting rod 121'; the other side of the connecting rod 121' is fixedly connected to the disassembly disc 11'.

[0020] Specifically, in the preparation stage before disassembly, the operator needs to move the slider 112' on the disassembly plate 11' towards the center of the disassembly plate 11' to the limit position (e.g., ...). Figure 3 (As shown). Specifically, the operator uses a wrench to loosen the nut of the adjusting bolt 111' fixed to the disassembly plate 11', thereby making the slider 112' slidable, and then moves it to the limit position. The ring support 3' is installed on one side of the corresponding bearing box 100, as shown. Figure 2 and Figure 3 As shown, its function is to support the three-pronged baffle 4' and prevent the three-pronged baffle 4' from being directly placed at the opening of the bearing housing 100, which would affect the disassembly of the bearing.

[0021] Furthermore, such as Figure 2 and Figure 3 The circular support 3' shown is installed at the opening of the bearing housing 100, and the three-pronged baffle 4' is installed on the circular support 3'. Specifically, the three-pronged baffle 4' is placed flat on the circular support 3' after passing through the gap in the middle of the connecting rod 121' vertically. It is worth noting that the function of the three-pronged baffle 4' is to support the hydraulic jack 21' in the hydraulic device 2'. Specifically, the hydraulic jack 21' needs to be placed on the center of the three-pronged baffle 4' by the operator (if the position of the hydraulic jack 21' is offset during the placement process, it will affect the stability of the subsequent disassembly process), and the bottom of the connecting block 122' is used to abut against the piston 211' of the hydraulic jack 21'. In the specific implementation process, because the three-pronged baffle 4' is installed first, in order to ensure that the hydraulic jack 21' is smoothly installed between the connecting block 122' and the three-pronged baffle 4', the piston 211' of the hydraulic jack 21' is initially in a tightened state. After being placed at the center of the three-pronged baffle 4', the operator manually supports the hydraulic jack 21' and controls the piston 211' of the hydraulic jack 21' to slowly extend. Then, the piston 211' causes the disassembly device 1' to connect with the ring support 3' through the three-pronged baffle 4'. Subsequently, pressure is continued to be applied to the piston 211', causing the disassembly device 1' to push the bearing 7 of the axle box outward.

[0022] Furthermore, after the bearing 7 of the bearing housing 100 is removed from the bearing housing 100 using the above method, the operator then uses an overhead crane to rotate the bearing housing 180° to disassemble the bearing 7 on the other side. Once both sides are disassembled, the disassembly process of the bearing housing 100 is complete. However, there are several technical defects in the operation of the aforementioned bearing housing disassembly fixture.

[0023] Firstly, the bearing disassembly fixture requires the assembly of various components. For example, individual components such as the disassembly plate 11', ring support 3', three-pronged baffle 4', and hydraulic jack 21' all need to be moved, aligned, and installed sequentially by operators. Each time one side of the axle box bearing 7 is disassembled, the entire assembly and installation process must be repeated. The pre-disassembly preparation alone requires two operators to coordinate with the overhead crane, significantly slowing down the overall locomotive overhaul progress. Furthermore, manual assembly and alignment makes it difficult to ensure that the force center of the hydraulic jack always coincides with the bearing's center. During operation, the fixture position needs to be adjusted manually multiple times, and the hydraulic jack must be held by hand. Incorrect adjustments can damage components or endanger personnel safety. In addition, the existing axle box bearing disassembly fixture mainly relies on the various components to be assembled under gravity, which is why the aforementioned axle box bearing disassembly fixture cannot disassemble both sides simultaneously. When the horizontally positioned axle box 100 is in place, the circular ring support 3' and the three-pronged baffle 4' cannot be stably installed, and the pre-installation and fixing of the double-sided tooling cannot be completed simultaneously in the horizontal position.

[0024] In this regard, such as Figure 4 , Figure 5 As shown, this application improves upon existing axle box disassembly devices. Specifically, this application's integrated axle box bearing 7 lateral disassembly device includes a disassembly mechanism 1, a telescopic device, a hydraulic mechanism 4, a pull rod 5, and a support mechanism 3. Specifically, the disassembly mechanism 1 includes a base plate 11 and at least two pull blocks 12 evenly distributed radially along the base plate 11. (Refer to...) Figure 4 , Figure 5 The pull-out blocks 12 are arranged in a three-dimensional configuration, evenly spaced along the circumference of the base plate 11. Each pull-out block 12 can be radially slidable to adjust its position, accommodating bearings 7 of different sizes and specifications. Specifically, the pull-out blocks 12 have a stepped structure, including a high platform 122 and a low platform 123. The high platform 122 has a guide groove 121, and the low platform 123 is used to form an axial clamping fit with the inner ring end face of the bearing 7. Furthermore, the height of the low platform 123 should be less than the assembly clearance 110 between the lower surface of the bearing outer ring and the bearing housing 100 to ensure that the low platform 123 can smoothly enter the housing. Figure 10 As shown, in the specific implementation process, the lower platform 123 serves as a snap-fit ​​flange on the side of the pull block 12 facing the bearing to be disassembled, which can be snapped into place during operation. Figure 11 The assembly gap 110 between the bearing inner ring and the shaft provides stable force support for pull-out disassembly.

[0025] Furthermore, a limiting pin 14 is fixedly provided on the end face of the base plate 11, and a guide groove 121 is provided on the pulling block 12. Specifically, the guide groove 121 is provided on the surface of the platform 122 and has a certain size, penetrating the entire upper and lower surfaces of the platform 122. The position and size of the guide groove 121 can ensure that the limit distance of the extension and retraction movement of the pulling block 12 can cover the size of the bearing outer ring. Specifically, the limiting pin 14 and the guide groove 121 form a sliding pair, which can restrict the movement of the pulling block 12 within the long groove, thereby restricting the movement stroke and radial movement freedom of the pulling block 12. Among them, the limiting pin 14 includes a smooth rod section 141 and a pin cap 142. The smooth rod section 141 is provided through the guide groove 121. One end of the smooth rod section 141 is fixedly connected to the base plate 11, and the other end is fixedly connected to the pin cap 142. The pin cap 142 can prevent the pulling block 12 from moving outward during the movement. In addition, a support block 15 is fixedly provided at the center of the end face of the base plate 11, one end of the pull block 12 is fixedly connected to one end of the spring 13, and the other end of the spring 13 is fixedly connected to the support block 15; the spring 13 can return the pull block 12 to its maximum limit position without external force. Figure 4 - Figure 9 As shown, the support block 15 is a polygon with the same number of sides as the number of pulling blocks 12. When there are three pulling blocks 12, the support block 15 is a triangular support block 15. The triangular support block 15 is installed at the center of the base plate 11, and its three end faces are parallel to the end faces of the pulling blocks 12.

[0026] Preferably, the base plate 11 is a circular plate of a certain thickness, and its outer diameter is smaller than the inner diameter of the bearing box 100. During operation, it can enter the inner hole of the bearing box 100 without interference. Its surface needs to be milled flat as a whole, and the flatness requirement is ±0.01mm to ensure that the components installed on the upper surface are in the same horizontal position.

[0027] Furthermore, the telescopic device is used to control the radial movement of the pulling block 12 along the base plate 11. In this application, the telescopic device includes various implementations, including using gears or a hydraulic mechanism 4 to achieve the telescopic function. It is worth noting that, as... Figure 6 and Figure 8 As shown, the telescopic device of this application preferably achieves the telescopic function of the pulling block 12 through a structure of telescopic sleeve 6, connecting rod, and spring 13. In specific implementation, the telescopic device includes a connecting rod mechanism 2 and a telescopic sleeve 6; wherein, as shown... Figure 6As shown, the linkage mechanism 2 has one end fixedly connected to the pulling block 12 and the other end hinged to the outer periphery of the pull rod 5. Specifically, the linkage mechanism 2 includes a first link 21, a second link 22, and a third link. One end of the first link 21 is fixedly connected to the surface of the platform 122. One end of the second link 22 is hinged to the lug 25 provided on the outer periphery of the pull rod 5. One end of the third link 23 is hinged to the other end of the first link 21 through a connecting pin 24, and the other end of the third link 23 is hinged to the other end of the second link 22 through a connecting pin 24. The telescopic sleeve 6 is sleeved on the outer periphery of the pull rod 5 and is disposed between the linkage mechanism 2 and the baffle 32. When the telescopic sleeve 6 is subjected to force and slides, it acts on the linkage mechanism 2, causing the linkage mechanism 2 to drive the pulling block 12 to move towards the support block 15.

[0028] In the specific implementation process, refer to Figure 6 and Figure 7 This is a schematic diagram of the telescopic device and disassembly mechanism 1 when the telescopic sleeve 6 is not subjected to external force. When the telescopic sleeve 6 is subjected to such... Figure 6 After an external force is applied in the direction indicated by the dotted line, the telescopic sleeve 6 moves toward the disassembly mechanism 1. For example... Figure 8 As shown, at this time, the telescopic sleeve 6 applies an external force to the second link 22, causing the connection side between the second link 22 and the third link 23 to gradually move towards the pull rod 5. The angle between the first link 21 and the third link 23 also decreases, thereby pushing the pull block 12, which is fixedly connected to the first link 21, to move towards the support block 15. At this time, the support block 15 simultaneously compresses the spring 13. In specific implementation, the operator tightens the pull block 12 through the telescopic sleeve 6 as follows: Figure 9 As shown, the disassembly mechanism 1 is then moved into the cavity of the bearing housing 100. Figure 11 and Figure 12 As shown, the operator can release the telescopic sleeve 6 when the pull block 12 is inside the cavity of the bearing housing 7. At this time, the pull block 12 begins to spread outward under the action of the spring 13 and abuts against the inner wall of the bearing housing 7. Further, the operator continues to push the disassembly mechanism 1 inward, and the lower platform 123 of the pull block 12 rubs against the inner ring of the bearing housing 7 and then engages in the assembly gap 110, thereby achieving the holding of the bearing housing 7. It is worth noting that, in order to reduce wear on the bearing housing 7, the operator can also choose to release the telescopic sleeve 6 when the lower platform 123 of the pull block 12 corresponds to the assembly gap 110, thereby achieving the holding of the bearing housing 7. Both of the above methods are within the protection scope of this application.

[0029] Furthermore, the disassembly device of this application also includes a hydraulic mechanism 4 and a support mechanism. For example... Figure 4 and Figure 5As shown, the hydraulic device includes a hydraulic cylinder 41 and a hydraulic pump 42 that drives the hydraulic cylinder 41 to move; the support mechanism 3 includes a baffle 32 and at least two push rods 31, which, in specific implementation, are as follows: Figure 4 The preferred configuration includes three push rods 31 and one baffle 32. The three push rods 31 are installed on the circumference of the baffle 32 with a diameter of 360 mm. During operation, the push rods 31 contact the end face of the bearing housing 100. It is worth noting that the baffle 32 is a circular plate of a certain thickness, capable of withstanding the pressure of the hydraulic pump 42. Its diameter must be larger than the maximum size of the labyrinth of the bearing housing 100 and able to cover the installation position of the push rods 31. Specifically, one end of the push rod 31 is fixed to the end face of the baffle 32, and the other end of the push rod 31 is used to contact the outer end face of the bearing housing 100. The other end face of the baffle 32, away from the push rod 31, is fixedly connected to the hydraulic cylinder 41. A pull rod 5 is installed through the baffle 32, the hydraulic cylinder 41, and the hydraulic pump 42. It is worth noting that one end of the pull rod 5 is fixedly connected to the top of the support block 15, and the other end of the pull rod 5 is fixed to the outside of the hydraulic cylinder 41. Figure 4 As shown, the end of the pull rod 5 away from the support block 15 has a threaded structure, which is used to install the gasket 43 and nut 44 in sequence to prevent the hydraulic pump 42 from moving. When the hydraulic pump 42 moves outward, the gasket 43 and nut 44 act as a stop, driving the pull rod 5, the disassembly mechanism 1 and the outer ring of the bearing 7 of the bearing box to move outward together.

[0030] Preferred, such as Figure 11 As shown, the hydraulic pump 42 of this application has an internal bore structure, but the bearing pulling effect can also be achieved through other structures.

[0031] In the specific implementation process, such as Figure 13 The diagram shows a cross-sectional view of the bearing 7 held in place by the pull block 12 inside the disassembly mechanism 1 during the disassembly of the bearing 7 in the axle box 100 structure using the integrated axle box bearing 7 disassembly device of this application. In the specific implementation process, the operator starts the hydraulic pump 42, causing the hydraulic cylinder 41 to extend outwards, driving the support mechanism 3 to move towards the outer end face of the bearing box 100 until the three push rods 31 on the support mechanism 3 are in contact with the end face of the bearing box 100. At this point, further, the hydraulic cylinder 41 is kept extended outwards, but... Figure 14As shown, since the support mechanism 3 is attached to the bearing housing 100 and no longer moves, the hydraulic cylinder 41 will remain stationary with the support mechanism 3 during its outward extension. However, the hydraulic cylinder 41 itself will drive the hydraulic pump 42 to move away from the bearing housing 100. The hydraulic pump 42 is limited by the washer 43 and nut 44 at one end of the pull rod 5, thus driving the pull rod 5 to move outward synchronously. The support block 15 connected to the other end of the pull rod 5 and the pull block 12 held on the outer ring of the bearing will then apply force outward synchronously, smoothly pulling the bearing housing 7 out of the bearing housing 100 cavity, completing the lateral disassembly of the bearing housing 7. Until the outer ring of the bearing is completely separated from the bearing housing 100, the hydraulic pump 42 is turned off to restore it to its original state. Thus, the lateral disassembly device for the bearing housing 7 is moved to the other side of the bearing housing 100 and the above operation is repeated to disassemble the bearing housing 7 on the other side.

[0032] Finally, this application also provides a method for lateral disassembly of the bearing housing 7, including the following steps: Step S1: Place the cleaned axle box horizontally in the axle box bearing 7 disassembly area, and adjust any of the above-mentioned integrated axle box bearing 7 horizontal disassembly devices to the center height of the axle box's circular hole, so that the center of the base plate 11 is aligned with the center of the axle box's circular hole. Step S2: Move the telescopic sleeve 6 towards the base plate 11. The telescopic sleeve 6 drives the connecting rod mechanism 2, causing the pulling block 12 to retract towards the support block 15 until the disassembly mechanism 1 can enter the inner hole of the bearing box. Step S3: Adjust the telescopic sleeve 6 to the initial position so that the pull block 12 is used to hold and engage the inner ring end face of the bearing 7 in the bearing box. Start the hydraulic pump 42 to move the hydraulic cylinder 41 toward the disassembly mechanism 1. The hydraulic cylinder 41 drives the support mechanism 3 to move toward the outer end face of the bearing box until the push rod 31 in the support mechanism 3 abuts against the outer end face of the bearing box. Step S4: Keep the hydraulic cylinder 41 moving toward the disassembly mechanism 1, and the pull rod 5 drives the disassembly mechanism 1 to move away from the bearing box until the bearing box bearing 7 is separated from the bearing box, and then turn off the hydraulic pump 42. Step S5: Move the entire lateral disassembly device of the integrated bearing box 7 to the other side of the bearing box, and repeat steps S1-S4 to disassemble the bearing box 7 on the other side of the bearing box.

[0033] It is worth noting that in this application, the end of the pull rod 5 or the hydraulic pump 42 in the disassembly device is connected and used in conjunction with the movable lifting trolley. This makes the production process easy to adjust and operate, and reduces costs. It can also be designed as a robotic arm structure to realize the lifting and moving function of the device. This reduces the labor intensity of operators and improves the safety and stability of the operation process. The integrated structural design provided by this solution integrates the support and force-applying components, eliminating the need for multiple adapter parts for different models of axle boxes. By simply adjusting the support position of the top rod 31 and the force-applying stroke of the hydraulic cylinder 41, it can adapt to the disassembly of various specifications of axle box bearings 7, resulting in greater versatility. The force is evenly and stably applied during the disassembly process, effectively preventing damage to the axle box body or bearings during disassembly, and improving the quality and efficiency of the disassembly operation.
