Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a disassembly device for disassembling the outer ring of a bearing. Background Technology

[0002] In industrial equipment, gearboxes are important transmission components and are widely used in various mechanical devices.

[0003] However, after prolonged operation, the bearings inside the gearbox often fail due to wear, deformation, or uneven stress, requiring regular maintenance or replacement. Because of the compact internal space of the gearbox, the bearing housings are mostly blind-bore designs, and there is an interference fit between the bearing outer ring and the blind bore. This makes it easy for the bearing outer ring to stick to the blind bore after a period of use. This is especially true for the high-speed shaft blade side bearings installed inside the gearbox. The presence of parallel gears outside these bearings restricts the operating space, making it difficult to effectively use traditional pullers and other general-purpose disassembly tools, thus hindering the disassembly of the bearing outer ring.

[0004] Therefore, there is an urgent need for a disassembly device for removing the outer ring of a bearing to solve the above-mentioned technical problems. Utility Model Content

[0008] A support mechanism includes a support base and a support tube, one end of which is connected to the support base, and the support tube extends along a first axis.

[0009] The support mechanism includes at least two support members, which are spaced apart around the first axis. The support members are slidably disposed on the bearing seat. The bearing seat can extend into the assembly hole of the bearing to be disassembled, such that the support member is located on one side of the axial direction of the bearing to be disassembled, and the bearing tube extends to the other side of the bearing to be disassembled.

[0010] The drive mechanism is capable of driving the support member to extend or retract radially along the bearing tube, so that the support member can abut against the axial end of the outer ring of the bearing to be disassembled.

[0011] Optionally, there are two support members, namely a first support member and a second support member, and the driving mechanism can drive the first support member and the second support member to move toward each other or toward each other.

[0012] Optionally, the driving mechanism includes a driving rod and a driving gear. The driving rod extends along the first axis and is connected to the driving gear to drive the driving gear to rotate around the first axis. The first support member and the second support member are both meshed with the driving gear.

[0013] Optionally, the disassembly device for disassembling the outer ring of the bearing further includes a limiting mechanism disposed on the bearing seat. The limiting mechanism includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are both sleeved on the outer peripheral wall of the drive rod, and the drive gear is limited between the first limiting member and the second limiting member.

[0014] Optionally, the limiting mechanism further includes a third limiting member, one end of the drive rod extends out of the bearing seat and is provided with a limiting groove, the third limiting member is disposed in the limiting groove and abuts against the bearing seat.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a disassembly device for removing the outer ring of a bearing, comprising a bearing support mechanism, a support mechanism, and a drive mechanism. The bearing support mechanism includes a bearing seat and a bearing tube. One end of the bearing tube is connected to the bearing seat, and the bearing tube extends along a first axis to facilitate inserting the bearing seat into the assembly hole of the bearing to be disassembled, thereby ensuring the device's operational flexibility and stability within a compact space. The support mechanism includes at least two support members. Since the support members abut against the outer ring of the bearing to be disassembled, the at least two support members spaced apart around the first axis ensure more even force distribution on the outer ring during disassembly, making the disassembly operation more stable and reliable. The bearing seat can extend into the assembly hole of the bearing to be disassembled, so that the support member is located on one side of the bearing's axial direction, and the bearing tube extends to the other side of the bearing to be disassembled. This allows the bearing seat and bearing tube to be operated from both sides of the bearing's outer ring, thereby achieving a smooth and efficient disassembly process and avoiding disassembly difficulties due to insufficient operating space. The support member is slidably mounted on the bearing seat. The drive mechanism can drive the support member to extend or retract radially along the bearing tube, thereby flexibly adjusting the contact position between the support member and the outer ring. This allows the support member to abut against the axial end of the outer ring of the bearing to be disassembled, providing stable support and thrust to the outer ring during disassembly. With the above configuration, the disassembly device for disassembling the bearing outer ring of this application can operate within a limited space, thus facilitating and quickly completing the disassembly of the bearing outer ring.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] In industrial equipment, gearboxes are important transmission components and are widely used in various mechanical devices.

[0038] However, after prolonged operation, the bearings inside the gearbox often fail due to wear, deformation, or uneven stress, requiring regular maintenance or replacement. Because of the compact internal space of the gearbox, the bearing housings are mostly blind-bore designs, and there is an interference fit between the bearing outer ring and the blind bore. This makes it easy for the bearing outer ring to stick to the blind bore after a period of use. This is especially true for the high-speed shaft blade side bearings installed inside the gearbox. The presence of parallel gears outside these bearings restricts the operating space, making it difficult to effectively use traditional pullers and other general-purpose disassembly tools, thus hindering the disassembly of the bearing outer ring.

[0039] Therefore, there is an urgent need for a disassembly device for removing the outer ring of a bearing to solve the above-mentioned technical problems.

[0040] like Figures 1-9 As shown, this embodiment provides a disassembly device for disassembling the outer ring of a bearing, which includes a bearing mechanism 1, a support mechanism 2, and a drive mechanism 3. The bearing mechanism 1 includes a bearing seat 11 and a bearing tube 13. One end of the bearing tube 13 is connected to the bearing seat 11, and the bearing tube 13 extends along a first axis. The support mechanism 2 includes at least two support members, which are spaced apart around the first axis. The support members are slidably disposed on the bearing seat 11. The bearing seat 11 can extend into the assembly hole of the bearing to be disassembled, so that the support member is located on one side of the axial direction of the bearing to be disassembled. The bearing tube 13 extends to the other side of the bearing to be disassembled. The drive mechanism 3 can drive the support member to extend or retract radially along the bearing tube 13, so that the support member can abut against the axial end of the outer ring of the bearing to be disassembled.

[0041] In this embodiment, the support mechanism 1 includes a support seat 11 and a support tube 13. One end of the support tube 13 is connected to the support seat 11, and the support tube 13 extends along the first axis to facilitate the insertion of the support seat 11 into the assembly hole of the bearing to be disassembled, thereby ensuring the operational flexibility and stability of the device in a compact space. The support mechanism 2 includes at least two support members. Since the support members are used to abut against the outer ring of the bearing to be disassembled, the at least two support members are spaced apart around the first axis, so that the outer ring can be subjected to more even force during disassembly, and the disassembly operation is more stable and reliable. The support seat 11 can extend into the assembly hole of the bearing to be disassembled, so that the support member is located on one side of the axial direction of the bearing to be disassembled, and the support tube 13 extends to the other side of the bearing to be disassembled, so that the support seat 11 and the support tube 13 can be operated from both sides of the outer ring of the bearing, thereby achieving a smooth and efficient disassembly process and avoiding disassembly difficulties due to insufficient operating space. The support member is slidably mounted on the bearing seat 11. The drive mechanism 3 can drive the support member to extend or retract radially along the bearing tube 13, thereby flexibly adjusting the contact position between the support member and the outer ring. This allows the support member to abut against the axial end of the outer ring of the bearing to be disassembled, providing stable support and thrust to the outer ring during disassembly. With the above configuration, the disassembly device for disassembling the bearing outer ring of this embodiment can operate within a limited space, thus facilitating and quickly completing the disassembly of the bearing outer ring.

[0042] It should be noted that, in this embodiment, the assembly hole of the bearing to be disassembled refers to the hole through which the outer ring of the bearing mates with the gearbox housing or other mounting components. Specifically, the outer ring of the bearing typically uses an interference fit or transition fit with the bearing hole in the gearbox housing through its outer cylindrical surface to achieve the fixing and positioning of the bearing. The assembly hole, on the other hand, refers to the hole inside the outer ring of the bearing, used to install the inner ring of the bearing and other components such as the shaft.

[0043] Furthermore, when the bearing seat 11 is inserted into the assembly hole of the bearing to be disassembled, the direction of the first axis coincides with the central axis of the outer ring of the bearing, so as to ensure that the bearing seat 11 and the bearing tube 13 can be smoothly inserted and operated along the axial direction of the outer ring of the bearing. The direction of the first axis will not be explained in detail here.

[0044] The specific structure of the disassembly device used to remove the outer ring of the bearing is described below:

[0045] Specifically, in this embodiment, there are two support members, namely a first support member 21 and a second support member 22, which are slidably connected to the bearing seat 11. The driving mechanism 3 can drive the first support member 21 and the second support member 22 to move toward each other or away from each other, so that the first support member 21 and the second support member 22 can be flexibly adjusted according to the size of the bearing to be disassembled, thereby adapting to bearing outer rings of different specifications to improve the versatility of the device.

[0046] More specifically, in this embodiment, both the first support member 21 and the second support member 22 are support plates, thus providing a larger contact area and more stably supporting the bearing to be disassembled. The bearing seat 11 has a through-type sliding passage 111, and both support plates are slidably disposed within the sliding passage 111 to guide the support plates. The driving mechanism 3 drives the two support plates to move synchronously towards each other along the same straight line, thereby ensuring that the contact areas between the two support plates and the bearing to be disassembled are approximately equal, thus improving the stability of the disassembly process.

[0047] In other embodiments, the first support member 21 and the second support member 22 may also be rod-shaped or block-shaped structures. The specific structure of the above-mentioned components is not limited here, as long as the above-mentioned functions can be achieved.

[0048] Specifically, the drive mechanism 3 includes a drive rod 31 and a drive gear 32. The drive rod 31 extends along the first axis and is connected to the drive gear 32, driving the drive gear 32 to rotate around the first axis. The first support member 21 and the second support member 22 are both meshed with the drive gear 32. When the drive gear 32 rotates, it drives the first support member 21 and the second support member 22 to move towards or away from each other. Through the above arrangement, precise movement of the first support member 21 and the second support member 22 is achieved, making operation simple and more reliable.

[0049] More specifically, the first support member 21 and the second support member 22 are respectively disposed on both sides of the drive gear 32 to ensure that the first support member 21 and the second support member 22 move independently and do not interfere with each other.

[0050] In other embodiments, the drive mechanism 3 includes a dual-head linear motor, which can directly provide bidirectional linear driving force, thereby driving the first support member 21 and the second support member 22 to move in directions toward each other or away from each other, thus simplifying the transmission structure and improving driving efficiency. It is understood that the specific structure of the drive mechanism 3 is not limited, as long as it can achieve the above-mentioned functions.

[0051] Specifically, the disassembly device for disassembling the outer ring of the bearing also includes a limiting mechanism 4 disposed on the bearing seat 11. The limiting mechanism 4 includes a first limiting member 41 and a second limiting member 42. The first limiting member 41 and the second limiting member 42 are both sleeved on the outer peripheral wall of the drive rod 31. The drive gear 32 is limited between the first limiting member 41 and the second limiting member 42, which can effectively limit the axial position of the drive gear 32, thereby ensuring the stable operation of the drive mechanism 3 and preventing the drive gear 32 from axially moving during rotation.

[0052] More specifically, in this embodiment, the first limiting member 41 is a cover plate and the second limiting member 42 is a spacer. The cover plate and the spacer are respectively spaced apart on the drive rod 31, so that the drive gear 32 is limited between the cover plate and the spacer, thereby achieving the limiting effect on the drive gear 32.

[0053] In other embodiments, the first limiting member 41 and the second limiting member 42 may also be a limiting block or a limiting sleeve, etc. The specific structure of the above components is not limited here, as long as the above functions can be achieved.

[0054] Specifically, the limiting mechanism 4 also includes a third limiting member 43. One end of the drive rod 31 extends out of the bearing seat 11 and is provided with a limiting groove 311. The third limiting member 43 is disposed in the limiting groove 311 and abuts against the bearing seat 11, thereby further improving the axial limiting effect of the drive rod 31, so that the drive rod 31 maintains a stable position in the bearing seat 11 and avoids axial movement during operation.

[0055] More specifically, in this embodiment, the third limiting member 43 is a retaining ring. The limiting groove 311 extends circumferentially along the drive rod 31, and the retaining ring is arranged in the limiting groove 311. By abutting against the end of the bearing seat 11 away from the force-applying member 12, the retaining ring can limit the drive rod 31. In other embodiments, the third limiting member 43 is a stop block, which can also achieve the above function. The specific structure of the third limiting member 43 is not limited here.

[0056] Specifically, the support 11 is provided with a receiving groove 112, and the drive rod 31 extends out of the support 11 and is placed in the receiving groove 112. This can effectively protect the drive rod 31 extending out of the support 11 and prevent the drive rod 31 from protruding from the opening end of the receiving groove 112 to the outside, thus preventing the drive rod 31 from being subjected to external collisions or interference.

[0057] Specifically, the end of the drive rod 31 furthest from the drive gear 32 is provided with a gripping part 312, which allows the operator to clamp the gripping part 312 with a wrench or other tools, thereby driving the drive rod 31 to rotate around its own axis, which in turn drives the drive gear 32 to rotate, causing the first support member 21 and the second support member 22 to move toward or away from each other. By providing the gripping part 312, the rotation operation of the drive rod 31 is made more convenient, improving the disassembly efficiency of the bearing outer ring.

[0058] More specifically, in this embodiment, the gripping part 312 has a cuboid structure, which provides a larger contact area to facilitate stable clamping by the operator. In other embodiments, the gripping part 312 may also use structures such as protrusions or turntables. The specific structure of the gripping part 312 is not limited here, as long as it can achieve the above-mentioned functions.

[0059] Specifically, the bearing tube 13 is disposed on the bearing seat 11 and sleeved on the outer peripheral wall of at least part of the drive rod 31, which can play a protective role for the drive rod 31. Moreover, the bearing tube 13 is provided with a force-applying member 12, which not only provides a stable installation position for the force-applying member 12, but also ensures that the force-applying member 12 accurately transmits power to the bearing seat 11.

[0060] More specifically, in this embodiment, the force-applying component 12 is a rod-shaped structure with good rigidity and strength, which can effectively transmit power to the bearing seat 11. Furthermore, this arrangement facilitates the operator in pulling the force-applying component 12, thereby moving the bearing seat 11 to achieve the disassembly of the bearing outer ring. In addition, two force-applying components 12 are provided, positioned on opposite sides of the bearing tube 13, resulting in a more balanced force application and improving the stability of the bearing seat 11's movement.

[0061] In other embodiments, four force-applying components 12 are provided and are plate-shaped. The four force-applying components 12 are arranged at intervals along the circumference of the bearing pipe 13, which can also achieve the above-mentioned function. Here, the specific structure and number of force-applying components 12 are not limited.

[0062] Specifically, the disassembly device for disassembling the outer ring of the bearing also includes a locking mechanism 5 disposed on the bearing seat 11. The locking mechanism 5 includes at least two locking members, which can abut against the support member one by one, thereby locking the support member to the bearing seat 11.

[0063] More specifically, in this embodiment, there are two locking components, namely a first locking component 51 and a second locking component 52. The first locking component 51 and the second locking component 52 can abut against the first support component 21 and the second support component 22 in a one-to-one correspondence, thereby locking the first support component 21 and the second support component 22 to the bearing seat 11, so as to improve the safety and reliability of the device and avoid damage to the outer ring of the bearing to be removed or the inability to be removed due to accidental sliding of the first support component 21 and the second support component 22.

[0064] Specifically, the support member is provided with a locking groove 211, and one end of the locking member can extend into the locking groove 211, thereby improving the locking effect on the support member.

[0065] More specifically, in this embodiment, both the first locking member 51 and the second locking member 52 are bolts, which are threadedly connected to the bearing seat 11. When the operator needs to lock the first support member 21 and the second support member 22 onto the bearing seat 11, the bolt is rotated so that the threaded part of the bolt extends into the locking groove 211 of the first support member 21 and the second support member 22. By the threaded part abutting against the bottom of the locking groove 211, the first support member 21 and the second support member 22 can be effectively locked onto the bearing seat 11, making the operation simpler and more convenient.

[0066] In other embodiments, the first locking member 51 and the second locking member 52 may also be selected from structures such as screws or pins. The specific structure of the above-mentioned components is not limited here, as long as the above-mentioned functions can be achieved.

[0067] Specifically, the first support member 21 and / or the second support member 22 are provided with an anti-slip part 212, which is configured to abut against the bearing to be disassembled, thereby increasing the friction between the first support member 21 and the second support member 22 and the bearing to be disassembled, improving the stability of the disassembly process, and preventing the outer ring of the bearing from sliding during the disassembly process.

[0068] More specifically, in this embodiment, the anti-slip part 212 includes multiple anti-slip grooves arranged at intervals, which can effectively increase the roughness of the contact surface, thereby improving the anti-slip effect. In other embodiments, the anti-slip part 212 includes multiple spaced-apart protrusions, which can also achieve the above-mentioned function. The specific structure of the anti-slip part 212 is not limited here.

[0069] The following describes the specific working process of the disassembly device used to remove the outer ring of the bearing:

[0070] To facilitate the removal of the bearing to be disassembled from the gearbox opening (such as the countersunk hole in this embodiment), the operator first moves the bearing seat 11 by using the force-applying component 12, causing the bearing seat 11 to extend into the assembly hole of the bearing to be disassembled. At this time, the first support component 21 and the second support component 22 are both placed at the end of the bearing to be disassembled near the bottom of the opening, while the force-applying component 12 is placed at the other end of the bearing to be disassembled. Then, the operator uses a wrench to hold the gripping part 312 and rotates the drive rod 31 to drive the drive gear 32 to rotate. The rotation of the drive gear 32 causes the first support component 21 and the second support component 22 to move toward each other or toward each other. To match the dimensions of the bearing outer ring, the first support 21 and the second support 22 are made to fully contact the force-bearing surface of the bearing to be disassembled near the bottom of the opening. Then, the first locking member 51 and the second locking member 52 are tightened, thereby locking the first support 21 and the second support 22 to the bearing seat 11 and preventing them from sliding. At this time, the operator moves the bearing seat 11 by applying force 12. The movement of the bearing seat 11 moves the first support 21 and the second support 22, thereby pushing the bearing to be disassembled out of the opening through the first support 21 and the second support 22, thus achieving a simple and efficient disassembly operation.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
