Description

Technical Field

[0001] The present invention relates to the technical field of bearing housing loading and unloading, and particularly relates to a bearing and bearing housing disassembly device based on a quick unlocking structure. Background Art

[0002] Taking a common flange spherical bearing housing as an example, it usually consists of a flange, a spherical bearing, and supporting connecting parts. The flange is firmly installed on the fixed base of the equipment through connecting parts such as bolts, providing a solid support platform for the bearing, and the spherical bearing is tightly nested in the seat hole of the flange.

[0003] In the process of equipment maintenance, overhaul, or component replacement, sometimes it is necessary to disassemble the bearing from the bearing housing. There are two main existing disassembly methods. One is to first rigidly fix the flange with a fixture to limit its displacement during disassembly, and then use a hammer to strike the outer ring of the bearing. By relying on the impact force generated by multiple strikes, the interference fit force and frictional force between the bearing and the seat hole are overcome, causing the bearing to gradually disengage from the seat hole. The other is to insert a stick into the inner ring of the bearing after fixing the flange to disengage it from the bearing housing.

[0004] The first disassembly method is likely to leave depressions and scratches on the surface of the outer ring of the bearing, thereby destroying the original precise circular contour of the bearing, resulting in uneven force distribution during rolling, and accelerating the wear and fatigue failure of the bearing. The second disassembly method will cause the outer ring, the edges of the inner ring, and the raceway to be deformed by extrusion, destroying the original precise circular structure of the bearing, making the running track of the rolling elements disordered, greatly increasing the vibration and noise during the operation of the bearing, and seriously affecting its rotation accuracy. Summary of the Invention

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a bearing and bearing housing disassembly device based on a quick unlocking structure, which can effectively solve the problems in the prior art that when disassembling a bearing from a bearing housing, the method of striking the outer ring of the bearing is likely to leave depressions and scratches on the surface of the outer ring, destroying its circular contour, resulting in uneven force during rolling, accelerating wear and fatigue failure, and when using the method of inserting a stick into the inner ring to disassemble the bearing, the outer ring, the edges of the inner ring, and the raceway of the bearing will be deformed by extrusion, causing the running track of the rolling elements to be disordered, increasing vibration and noise, and seriously affecting the rotation accuracy.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention will be further described below with reference to the embodiments. Embodiment

[0031] Refer to Figures 1-9 , a bearing and bearing housing disassembly device based on a quick unlocking structure, comprising: A clamping part 1, the clamping part 1 includes a mounting seat 11, a semi-circular plate 12 with an upward opening is slidably mounted on the mounting seat 11, and a clamping mechanism 13 for clamping a flange spherical bearing housing is connected to the semi-circular plate 12.

[0032] A positioning part 2, the positioning part 2 includes a support 21, the support 21 is fixedly connected to the mounting seat 11, and a positioning mechanism 22 for clamping and positioning a flange spherical bearing housing is fixedly connected to the support 21.

[0033] A knocking part 3, the knocking part 3 includes a semi-circular frame 31, the semi-circular frame 31 is slidably connected to the mounting seat 11 and an arc-shaped groove 32 is formed through the inner surface of its circumference, and a knocking mechanism 33 for separating the flange and the spherical bearing is commonly connected to the semi-circular frame 31 and the semi-circular plate 12.

[0034] Among them, the knocking mechanism 33 includes a first impact block 331, two first impact blocks 331 are symmetrically fixedly connected to the two ends of the semi-circular plate 12 left and right, two second impact blocks 332 corresponding to the first impact blocks 331 are fixedly connected to the semi-circular frame 31, and the left second impact block 332 is located above the left first impact block 331, and the right second impact block 332 is located below the right first impact block 331. A linkage assembly 333 is commonly connected to the mounting seat 11 and the semi-circular frame 31.

[0035] During specific implementation, the clamping mechanism 13 is used to clamp the flange in the spherical bearing seat of the flange to be disassembled. Then, the positioning mechanism 22 is used to perform outward expansion and centering positioning on the spherical bearing. Thus, while adjusting the flange and the spherical bearing to directly above the half-ring plate 12, the spherical bearing is also clamped and fixed. Then, an operator manually operates the linkage assembly 333 to drive the half-ring frame 31 to rotate clockwise first and then counterclockwise. Further, the first impact block 331 on the left strikes the second impact block 332 from top to bottom, and at the same time, the first impact block 331 on the right strikes the second impact block 332 from bottom to top. Thereby, opposite-direction forces are simultaneously applied to the two clamping mechanisms 13 on the left and right, driving the half-ring plate 12 and the clamping mechanism 13 to rotate clockwise synchronously, and further driving the flange to rotate counterclockwise relative to the spherical bearing (the above knocking process may be repeated multiple times according to the different connection tightness between the spherical bearing and the flange).

[0036] The above disassembly method has the following advantages compared with the conventional disassembly method. On the one hand, the knocking does not directly occur on the flange and the spherical bearing, which can avoid damaging the flange and the spherical bearing to the greatest extent. On the other hand, in the conventional disassembly method, the bearing is generally knocked at a single point, which is likely to cause damage to the bearing itself, affecting the accuracy and service life of the bearing. However, by using the method of simultaneously applying opposite-direction forces on both sides, the force acts relatively evenly and gently, which can effectively avoid direct impact on the bearing surface and internal structure, thereby protecting the bearing from damage. In addition, when directly knocking, the acting direction of the knocking force is difficult to control, and it is easy to have the situation that the knocking position is inaccurate. However, applying forces on both sides can specifically make the spherical bearing gradually and evenly disengage from the installation position, and can disassemble the spherical bearing more quickly and effectively, saving disassembly time and labor costs.

[0037] The clamping mechanism 13 includes a connecting seat 131. The connecting seat 131 is fixedly connected to both of the first impact blocks 331. An adaptive clamping component 133 is connected to the connecting seat 131 through a spring seat 132. The two adaptive clamping components 133 are symmetrically distributed about the center, and the geometric axis of the half-ring plate 12 is the center of symmetry of the two.

[0038] The adaptive clamping assembly 133 on the right side includes a clamping seat 1331. The clamping seat 1331 is fixedly connected to the movable section of the spring seat 132. A pressure plate 1332 is slidably connected up and down inside the clamping seat 1331. One end of the pressure plate 1332 close to the center of the semi-circular plate 12 is designed in a bent manner, so that the height of the gap between the pressure plate 1332 and the bottom of the clamping seat 1331 gradually decreases from the inside to the outside along the radial direction of the semi-circular plate 12, facilitating the operator to place the spring seat 132 therein. The upper end of the pressure plate 1332 is fixedly connected to a compression spring 1333. The compression spring 1333 is connected to the clamping seat 1331 through... Corresponding relief grooves 1334 are also provided on the pressure plate 1332 and the clamping seat 1331. The installation method of the left-side adaptive clamping assembly 133 is the same as that of the right-side adaptive clamping assembly 133. The difference is that a bolt 1335 for further locking the left-side pressure plate 1332 is also connected to the upper end of the clamping seat 1331 of the left-side adaptive clamping assembly 133 by means of a thread.

[0039] The positioning mechanism 22 includes a lever 221. There are two levers 221 symmetrically arranged left and right, which are used for internally expanding and clamping the bearings in the bearing seat. A rubber sleeve 222 for protection is fixedly sleeved on the upper end of the lever 221. The lower ends of the two levers 221 are jointly connected to a height adjustment assembly 223. The lever 221 and the height adjustment assembly 223 are jointly connected to a distance adjustment assembly 224.

[0040] The height adjustment assembly 223 includes a cylindrical seat 2231. The cylindrical seat 2231 is a cavity structure with an opening at the upper part. The lower end of the cylindrical seat 2231 is fixedly connected to a first turning handle 2232. The first turning handle 2232 is connected to the support 21 by means of a thread. The support 21 is fixedly connected to the mounting seat 11. Two inclined slots 2233 are penetrated and opened on the circumferential outer surface of the cylindrical seat 2231. Two straight slots 2234 corresponding to the inclined slots 2233 and extending in the up and down direction are symmetrically provided on the support 21. A guide rod 2235 is fixedly connected to the lever 221. The guide rod 2235 is slidably connected in the corresponding inclined slots 2233 and straight slots 2234.

[0041] The distance adjustment assembly 224 includes an adjustment rod 2241. The upper end of the adjustment rod 2241 is fixedly connected to a second turning handle 2242. The second turning handle 2242 is connected to the upper end of the support 21 by means of a thread. The lower end of the adjustment rod 2241 is rotatably connected to the cylindrical seat 2231, and the adjustment rod 2241 can move upward relative to the cylindrical seat 2231. A cam 2243 is slidably sleeved on the adjustment rod 2241. The lever 221 is slidably connected to the cam 2243 through a slider fixedly connected to its circumferential outer surface.

[0042] The linkage assembly 333 includes a half gear 3331. Two half gears 3331 are symmetrically and fixedly connected to the front and rear of the circumferential outer surface of the half-ring frame 31. A push-pull plate 3332 is slidably connected to the left and right on the mounting seat 11. Rack bars 3333 meshing with the half gears 3331 are symmetrically and fixedly connected to the front and rear of the push-pull plate 3332. A handle is fixedly connected to the left end of the push-pull plate 3332.

[0043] The knocking mechanism 33 further includes an arc-shaped block 334. The arc-shaped block 334 is fixedly connected to the circumferential inner surface of the half-ring plate 12. Two limiting plates 335 cooperating with the arc-shaped block 334 are symmetrically and fixedly connected to the mounting seat 11.

[0044] During specific implementation, initially, the first turning handle 2232 and the second turning handle 2242 are both rotated to relatively leftward positions. In this state, the cam 2243 points in the front and rear directions, the two lever rods 221 are in a state of approaching each other, the guide rod 2235 is in a relatively lower position in the inclined slot 2233, and the lower ends of the two lever rods 221 are also in a relatively lower position in the cylindrical seat 2231.

[0045] When the bearing seat needs to be disassembled, first insert the right end of the flange into the gap formed by the right-side pressing plate 1332 and the clamping seat 1331, and then insert the left end of the flange into the gap between the left-side pressing plate 1332 and the clamping seat 1331. After installation, the two pressing plates 1332 press the flange against the clamping seat 1331 under the action of the compression spring 1333, thereby realizing the clamping of the flange. During the installation process, the spring seat 132 will adaptively expand and contract. On the one hand, it facilitates the operation of the operator, and on the other hand, it also enables the two clamping seats 1331 to adaptively move left or right by a certain distance, so as to realize the clamping of flanges with different size specifications within a certain range, improving the versatility.

[0046] A stop pin is usually fixedly connected to the outer surface of the spherical bearing in the bearing seat. Correspondingly, a notch cooperating with the stop pin is reserved on the inner circumferential inner surface of the flange. When installing the shaft spherical bearing on the clamping seat 1331, it is necessary to make the end of the flange with the notch face downward, and at the same time, align the notch corresponding to the stop pin with the right-side clamping mechanism 13. The mounting holes of some flanges are designed as convex shapes as guiding structures during installation, which may cause obstacles to clamping. Therefore, a relief groove 1334 is provided on the pressing plate 1332 to adapt to the convexity on the surface of this type of flange.

[0047] After the clamping is completed, it is necessary to center the flange relative to the semi-ring plate 12 in the left-right direction. To achieve the above purpose, first rotate the first turning handle 2232 to the right, driving the cylindrical seat 2231 to rotate to the left. During this process, under the combined action of the straight groove 2234 and the inclined groove 2233, the guide rod 2235 slides upward, driving the lever 221 to move upward into the spherical bearing. At the same time, since the first turning handle 2232 and the straight groove 2234 seat are connected by a thread, and the thread has a self-locking effect, it can ensure that the guide rod 2235 will not fall back under its own gravity after sliding to the upper side. During the above process, the rotation of the first turning handle 2232 will also drive the cylindrical seat 2231 to slide upward a certain distance through the thread. However, since the number of turns of the first turning handle 2232 is less than half a turn, the upward movement distance of the cylindrical seat 2231 is also small and will not cause an impact.

[0048] After the lever 221 moves upward into the spherical bearing, turn the second turning handle 2242 to the right, driving the cam 2243 to turn to the right, and then driving the two levers 221 to move synchronously in the opposite direction, driving the flange to slide on the clamping seat 1331 until the left and right rubber sleeves 222 abut against the left and right inner circumferential surfaces of the spherical bearing. At this time, the flange is adjusted to the center, and the spherical bearing is also clamped and expanded inward. Since the support 21 and the second turning handle 2242 are connected by a thread, the second turning handle 2242 remains in place after rotation to ensure the clamping and fixing of the spherical bearing. After the flange is positioned, tighten the bolt 1335 to complete the locking of the left pressing plate 1332.

[0049] After the clamping and positioning of the flange and the spherical bearing are completed, the disassembly of the two is started. The specific process is as follows: The operator holds the handle and pulls the push-pull plate 3332 to the left, driving the semi-gear 3331 and the semi-ring frame 31 to rotate clockwise synchronously through the rack 3333 on it. At the same time, the left second impact block 332 rotates to a high position, and the right second impact block 332 rotates to a low position. Since the spherical bearing is fixedly clamped by the rubber sleeve 222 and is in a horizontal state, the semi-ring plate 12 is also in a relatively balanced state under the action of the clamping mechanism 13, and the two first impact blocks 331 are also on the same horizontal line. After pulling the push-pull plate 3332 to the left for a certain distance, the operator quickly pushes the push-pull plate 3332 to the right, driving the semi-gear 3331 and the semi-ring frame 31 to rotate counterclockwise synchronously through the rack 3333. Then the left second impact block 332 impacts the first impact block 331 from top to bottom, and the right second impact block 332 strikes the first impact block 331 from bottom to top, driving the semi-ring plate 12 to rotate through the same magnitude and opposite direction of the acting force, and then driving the flange to rotate counterclockwise relative to the spherical bearing through the clamping seat 1331.

[0050] It is worth noting that, depending on the tightness of the connection between the flange and the spherical bearing, the above-mentioned impact process may sometimes be repeated multiple times, so the rotation of the flange relative to the spherical bearing may not be completed in one go, but a gradual process (that is, each impact will cause the flange to rotate a certain angle relative to the spherical bearing, and as the impact progresses, the angle will gradually accumulate until the angle between the two reaches a specific angle). The advantage of the above-mentioned knocking method is that each time the impact block No. 1 331 and the impact block No. 2 332 collide head-on, that is, each force applied is in the opposite direction of the tangent of the semi-ring plate 12, which prevents additional axial force from acting on the flange and the spherical bearing through the clamping seat 1331 and the lever 221, thereby avoiding damage to the spherical bearing or the flange as much as possible.

[0051] After several collisions, when the semi-ring plate 12 rotates until the arc block 334 contacts the limit plate 335, the flange and the spherical bearing reach the maximum rotation angle. At this time, the No. 1 turning handle 2232 and the No. 2 turning handle 2242 are respectively turned left so that the two levers 221 first move downward and then move in the same direction to release the inward expansion of the spherical bearing. Then, the flange and the spherical bearing are synchronously removed from the clamping seat 1331, and then the two are separated manually, and the disassembly is completed.

[0052] The bearing and bearing seat disassembly device based on the quick unlocking structure has the following advantages: Advantage 1: The adaptive clamping assembly 133 in the clamping mechanism 13 of this embodiment has the same structure on the left and right sides and is symmetrically distributed about the center of the semi-ring geometric axis. Since the adaptive clamping assemblies 133 on the left and right sides are subjected to different forces during disassembly, this centrally symmetrical clamping method enables the clamping seat 1331 to completely transfer the received force to the flange, thereby avoiding differences in the magnitude of the forces applied to the two ends of the flange. The clamping seat 1331 in the adaptive clamping assembly 133 is connected to the movable section of the spring seat 132. When the flange is installed, the spring seat 132 can be adaptively retracted. After the operator installs the flange into the gap formed by the pressure plate 1332 and the clamping seat 1331, the pressure plate 1332 presses the flange under the action of the compression spring 1333. During this process, the two clamping seats 1331 can adaptively move to the left or right according to the size of the flange, thereby achieving clamping of flanges of different sizes within a certain range.

[0053] Advantage 2: For conventional disassembly methods, such as using a hammer to strike the outer ring of the bearing, it will directly leave depressions and scratches on the bearing surface. These marks will damage the originally precise circular contour of the spherical bearing, causing uneven stress during the rolling process, accelerating the wear and fatigue failure of the spherical bearing. However, for the disassembly method in this embodiment, the force generated by the impact between the first impact block 331 and the second impact block 332 acts on the half-ring plate 12, and then the flange is driven to rotate relative to the spherical bearing through the clamping seat 1331, thereby achieving disassembly. This can avoid damaging these key components to the greatest extent.

[0054] Advantage 3: For the conventional method of single-point striking the bearing, since the force is concentrated at one point, it is easy to cause excessive local stress on the spherical bearing, resulting in extrusion deformation at the edges of the outer ring, inner ring, and raceway. The disassembly method in this embodiment applies reverse forces simultaneously on both sides. The first impact blocks 331 and the second impact blocks 332 on the left and right sides work simultaneously, making the force evenly distributed on the flange and the spherical bearing. This uniform force application method effectively avoids direct impact on the surface and internal structure of the spherical bearing, protects the precise structure of the spherical bearing, and extends the service life of the spherical bearing.

[0055] Advantage 4: When conventionally disassembling the bearing seat, generally, the spherical bearing is directly struck. The direction of the force is difficult to control, and it is easy to have inaccurate striking positions. However, for the disassembly method provided in this embodiment, the operator holds the handle to pull and push the pull plate 3332, driving the half-gear 3331 and the half-ring frame 31 to rotate. As a result, each time the first impact block 331 and the second impact block 332 collide head-on, the applied force is along the tangent direction of the half-ring plate 12. This ensures that no additional force acts on the flange and the spherical bearing through the clamping seat 1331 and the lever 221, avoiding the position deviation of the flange caused by the additional force or excessive stress on the inner surface of the spherical bearing, and thus ensuring the safety and reliability of the disassembly process.

[0056] Advantage 5: In this embodiment, since multiple ineffective strikes are avoided, damage to the components is reduced, and there is no need to spend extra time dealing with damaged components, thus saving disassembly time and labor costs. Moreover, by optimizing the force application method and operation process, the overall disassembly efficiency is greatly improved, meeting the requirements for efficient disassembly during equipment maintenance, repair, or component replacement.
