Description

Technical Field

[0001] This invention relates to the field of bearing replacement equipment technology, and more specifically to a bearing quick removal device. Background Technology

[0002] Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission. In other words, when other machine parts move relative to each other on a shaft, they are used to reduce the coefficient of friction during power transmission and maintain the fixed position of the shaft's center. Bearings are a crucial component in modern mechanical equipment. Their main function is to support rotating mechanical parts and reduce the coefficient of friction of mechanical loads during transmission.

[0003] The application of bearings is quite widespread. Depending on the needs, the classification of bearings is becoming more and more complete and the types are becoming more and more numerous. In large mechanical equipment, especially in rotating shafts, bearings are needed to bear axial or radial loads.

[0004] During use, the balls or needle rollers of a bearing will wear down, causing a gap to form between the originally tightly fitted inner and outer rings. At this time, the cage of the balls or needle rollers in the middle is prone to breakage and damage. Damaged bearings need to be replaced in time to ensure the normal use of machinery, so it is very important to remove the damaged bearings quickly.

[0005] However, replacing the bearings in an oxidation blower requires removing the inlet and outlet flange bolts, opening the blower's roof, hoisting out all the inlet and outlet pipes, and then lifting and transporting the blower body to the maintenance platform. The front and rear end covers of the blower must be completely removed, the two impellers taken out of the body, the gears disassembled, and only then can the bearings be removed. This entire process is not only cumbersome but also time-consuming and labor-intensive, consuming a significant amount of manpower and time. The idleness of the machinery results in a direct economic loss. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0066] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0067] Please see the appendix Figure 1-4 The present invention discloses a bearing quick removal device, comprising:

[0068] Box component 1, the box component 1 has an internal mounting cavity, an open top structure, and a mounting plate 101;

[0069] The box component 1 is specifically a rectangular box structure with an opening at the top and a through hole at the bottom;

[0070] The first sliding groove component 2 is disposed in the mounting cavity and is arranged symmetrically.

[0071] The first sliding groove component 2 is a longitudinal groove structure, and the first sliding groove component 2 is provided on both side plates of the box component 1; the lifting component 3 is provided in the mounting cavity, and the first slider component 31 is symmetrically arranged on it;

[0072] The lifting component 3 is a fixed plate structure with protrusions on both sides. The protrusions are slidably connected to the first slider component 31. The lifting component 3 has a threaded hole at its center.

[0073] The first driving component 5 is disposed on the mounting plate 101;

[0074] The first driving component 5 can be one of a stepper motor or a handheld rotating component;

[0075] Main spindle component 4 is threadedly connected to lifting component 3, and one end of it is fixedly connected to the output end of first drive component 5.

[0076] The main shaft component 4 is a threaded rod structure, and its top is connected and fixed to the output shaft of the first drive component 5 through a connector. The main shaft component 4 is connected to the threaded hole of the lifting component 3.

[0077] The clamping component 6 is arranged in a ring array on the lifting component 3. It is rotatably connected to the lifting component 3 and is fixed by a nut.

[0078] The clamping component 6 is a rod-type structure, with a thread at one end that passes through the lifting component 3, and the clamping component 6 is fixed by a nut;

[0079] The gripper component 7 is located at the bottom of the clamping component 6 and is fixedly connected to the clamping component 6.

[0080] The gripper component 7 is specifically a limiting block structure, preferably a circular, double-claw structure, and the gripper component 7 and the clamping component are welded together.

[0081] The technical effects achieved by the above technical solution are as follows: the first driving component 5 rotates, driving the main shaft component 4 to rotate. At this time, the lifting component 3 will move longitudinally along the first sliding groove component 2 under the action of the rotation of the main shaft component 4, and the direction of movement is related to the direction of rotation. By adjusting the direction of the gap between the gripper component 7 and the bearing, the gripper component 7 passes through the gap between the bearing balls. When the gripping component 6 is rotated, the gripper component 7 contacts the inner and outer rings of the bearing. Then, it is locked and fixed by the nut, driving the first driving component 5 to reverse and lift, so that the lifting component 3 rises and then the corresponding bearing component is taken out.

[0082] The first drive component 5 drives the spindle component 4 to generate a helical axial force, which can quickly remove the bearing parts. It is suitable for use in environments with narrow gaps, making it more convenient to use and greatly improving maintenance efficiency.

[0083] To further optimize the above technical solution, please refer to the appendix. Figure 5-9 In one embodiment of this application, it further includes: an adjusting component 8, which is disposed within the mounting cavity;

[0084] Adjustment component 8 includes:

[0085] The central shaft component 9 is a hollow tubular structure that is fixedly connected to the mounting plate 101; specifically, the central shaft component 9 is a fixed shaft structure that is fixed to the mounting plate 101.

[0086] The main spindle component 4 is located at the center of the central spindle component 9, and the two do not contact each other;

[0087] The first rotating component 10 is disposed on the central shaft component 9 and is rotatably connected to the central shaft component 9.

[0088] The first rotating component 10 is a gear structure, which is rotatably connected to the central shaft component 9, meaning that the first rotating component 10 can rotate around the central shaft component 9;

[0089] The second slide rail component 32 is arranged in a ring array on the lifting component 3;

[0090] The second sliding groove component 32 is specifically a rectangular groove structure;

[0091] The third slide rail component 1001 is arranged in a ring array on the first rotating component 10;

[0092] The third slide rail component 1001 is specifically an arc-shaped groove structure;

[0093] The second slide rail component 32 is positioned corresponding to the third slide rail component 1001;

[0094] The second slider component 11 is disposed in the second slide groove component 32, and a clamping component 6 is provided at its bottom.

[0095] The second slider component 11 is specifically a rectangular block structure that extends through the second slide groove component 32 and has protrusions on its two end faces to prevent the second slider component 11 from detaching from the second slide groove component 32.

[0096] The third slider component 12 is disposed in the third slide groove component 1001 and is fixedly connected to the top of the second slider.

[0097] The third slider component 12 is specifically a limiting rod, which passes through the third slide groove component 1001. The length of the limiting rod is selected according to actual needs.

[0098] The specific length of the limit rod should be greater than the longitudinal displacement distance of the actual lifting component 3;

[0099] A limiting component 13 is provided on the third slider component 12 and is fixedly connected to the third slider component 12.

[0100] A through-slot component is provided on the housing component 1, and its position corresponds to that of the first rotating component 10, so as to facilitate the second rotating component 112 to rotate by a driving device.

[0101] The technical effect of the above technical solution is as follows: the driving device provides a driving force to the first rotating component 10, causing the first rotating component 10 to rotate, thereby causing the third slider component 12 to move along the arc groove of the first rotating component 10, thereby driving the second slider component 11 to move in the second sliding groove component 32, thereby changing the spacing between the clamping components 6, so as to be suitable for the use of bearings of various sizes.

[0102] During the movement of the second slider component 11 and the third slider component 12, the lifting component 3 will not undergo longitudinal displacement. Since the length of the limiting rod is selected according to actual needs and the limiting component 13 is provided on the limiting rod, it is not necessary to consider whether the limiting rod will disengage from the arc groove during the descent of the lifting component 3.

[0103] By using gear rotation to drive the movement of the limit rod, the spacing of the clamping component 6 is changed, which not only makes the adjustment more precise, but also makes it more convenient to use, thus making the overall applicability stronger.

[0104] To further optimize the above technical solution, please refer to the appendix. Figure 10-11 In one embodiment of this application, a rotating component is further included, which is disposed in the second slider component 11 and is rotatably connected to the clamping component 6.

[0105] The rotating parts include:

[0106] A rotating groove 111 component is disposed in the second slider;

[0107] The second rotating component 112 is disposed in the rotating groove 111 component and has an internal tooth structure. The second rotating component 112 and the rotating groove 111 component are fixedly connected.

[0108] The third rotating component 113 is disposed on the clamping component 6. The third rotating component 113 has an external tooth structure and is meshed with the second rotating component 112.

[0109] The first limiting plate component 114 is disposed on the clamping component 6 and is slidably connected to the second rotating component 112.

[0110] The first limiting plate component 114 is specifically an arc-shaped plate structure, which is connected to the clamping component 6 through a rotating shaft 116, and the rotating shaft 116 is provided with an elastic element.

[0111] The second limiting plate component 115 is disposed on the clamping component 6 and is slidably connected to the second rotating component 112.

[0112] The first limiting plate is located above the second limiting plate;

[0113] The second limiting plate component 115 is specifically an arc-shaped plate structure, which is connected to the clamping component 6 through a rotating shaft 116, and the rotating shaft 116 is provided with an elastic element.

[0114] The arc direction of the second limiting plate component 115 is opposite to the arc direction of the first limiting plate component 114;

[0115] The technical effects achieved by the above technical solution are as follows: In use, the first limiting plate and the second rotating component 112 are not in contact, the second limiting plate component 115 is in contact with the second rotating component 112, and there is a gap between the third rotating component 113 and the bottom of the rotating groove 111. By rotating the clamping component 6, the third rotating component 113 on the clamping component 6 rotates on the second rotating component 112, thereby adjusting the position and direction of the gripper component 7. After adjustment, the clamping component 6 is rotated again, so that the gripper component 7 contacts the inner and outer rings of the bearing component. By moving the lifting component 3 upward, the third rotating component 113 moves downward. At this time, the first limiting plate component 114 moves downward, and the teeth of the first limiting plate component 114 and the second rotating component 112 come into contact, so that the clamping component 6 avoids rotation when the teeth of the first limiting plate component 114, the second limiting plate component 115 and the second rotating component 112 are locked together.

[0116] To further optimize the above technical solution, please refer to the appendix. Figure 12 In one embodiment of this application, a handheld component 14 is further included, the output end of which is engaged with the first rotating component 10 of the adjusting component 8;

[0117] Handheld component 14 includes:

[0118] Housing component 141, wherein the housing component 141 has an internal mounting cavity;

[0119] The second drive component 142 is disposed in the mounting cavity, and its output shaft is provided with an active component 145.

[0120] The second drive component 142 is specifically a stepper motor, and its output shaft is equipped with a drive gear.

[0121] Driven component 146 is disposed in the mounting cavity via a rotating shaft 116 and is engaged with the driving component 145;

[0122] The driven component 146 is specifically a gear structure;

[0123] The driven component 146 is engaged with the first rotating component 10 of the adjusting component 8;

[0124] The control board component 143 is disposed inside the housing component 141 and is electrically connected to the second drive component 142.

[0125] The power supply component 144 is located inside the mounting cavity and is electrically connected to the control board component 143.

[0126] The technical effects achieved by the above technical solution are as follows: the power supply component 144 supplies power to the control board component 143 and the second drive component 142. The control board component 143 controls the operation of the second drive component 142, causing the active component 145 to rotate, which in turn drives the driven component 146 to rotate. The driven component 146 engages with the first rotating component 10 through the through slot of the housing component 1, driving the first rotating component 10 to rotate, thereby adjusting the spacing of the clamping component 6, making the operation more convenient.
