Description

Technical Field

[0001] This invention relates to the field of mechanical device technology, and in particular to a bearing replacement device that synchronously lubricates the bearing during installation. Background Technology

[0002] A wind turbine is a device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. Bearings are an essential component inside a wind turbine. After a period of use, the large bearings inside a wind turbine need to be disassembled and replaced to ensure their efficiency. This involves lubrication, maintenance, and repair to improve the equipment's availability and efficiency. Bearing disassembly typically uses hydraulic pullers or internal pullers.

[0003] Existing internal pullers can only disassemble bearings, not install them. Furthermore, bearings require heating with an electromagnetic heater before installation, resulting in extremely hot bearings that can burn operators during installation. Disassembly also requires manual rotation of the handle. Additionally, when installing a new bearing after replacement, operators must manually apply fresh grease evenly to ensure lubrication. These factors make bearing replacement cumbersome, waste manpower, and extremely inconvenient.

[0004] Therefore, it is necessary to design a bearing replacement device that can automatically complete the bearing lubrication operation while the bearing is being installed, in order to address the above problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] This invention addresses the problem that existing internal pullers cannot simultaneously meet the needs of bearing disassembly and installation, and that bearings require manual and even application of new grease during installation.

[0007] Therefore, the purpose of this invention is to provide a bearing replacement device that simultaneously applies grease during bearing installation. The purpose is to provide a tool that can both disassemble and install bearings, and this tool can uniformly apply grease to the new bearing while it is being installed.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bearing replacement device for synchronous oiling during bearing installation, comprising an inner hole puller, the inner hole puller comprising a rotating shaft and a fixed outer shaft, the rotating shaft being threadedly sleeved inside the fixed outer shaft, the rotating shaft being electrically connected to a motor; and an oiling unit comprising a sliding ring, the sliding ring being sleeved on the fixed outer shaft, one side of the sliding ring being provided with a brush, and the other side being provided with a sinking component.

[0009] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, the sinking assembly includes a ring seat and several sets of connecting shafts. Both ends of the connecting shafts are provided with balls, which are fitted inside universal ball seats and can rotate within the universal ball seats without falling off. The universal ball seats at both ends of the same connecting shaft are respectively fixed on the surfaces of the ring seat and the sliding ring.

[0010] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, wherein: an annular insertion groove is provided in the ring seat, an insertion frame is fixedly provided on the rotating shaft, the outer ring of the insertion frame is an annular driven ring, and the driven ring is fitted in the insertion groove.

[0011] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, the outer ring of the insertion groove is provided with several sets of receiving spaces in the circumferential direction, and the driven ring is provided with several sets of rebound plates; a magnet is embedded inside the end of the rebound plate, and a magnet is also embedded in the corresponding position inside the driven ring, and the number of rebound plates is the same as the number of receiving spaces; the diameter of the insertion groove is slightly larger than the diameter of the rotating shaft.

[0012] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, the sliding ring has an oil storage chamber, a cover is slidably disposed in the oil storage chamber, and the cover slides to the opening of the oil storage chamber to seal the oil storage chamber; the cover is fixed to the inner wall of the oil storage chamber by a spring, and the brush is fixedly disposed on the cover.

[0013] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, the fixed outer shaft is provided with a plurality of guide grooves along the long axis of the outer wall, and the fixed outer shaft is provided with an annular rotating groove along the circumferential direction of the outer wall, with the end of the guide groove away from the motor connected to the rotating groove; a guide block is provided on the inner wall of the sliding ring, and the guide block is slidably disposed in the guide groove.

[0014] As a preferred embodiment of the bearing replacement device for synchronous oiling during bearing installation as described in this invention, it further includes a bearing body, wherein a cylinder is fixedly installed at the end of the fixed outer shaft away from the motor, and the cylinder abuts against the bearing body.

The shrinking ring inside the bearing provides greater friction to assist in bearing replacement; 4. In addition, the use of a motor-driven rotating shaft to replace manual rotation with a hand handle makes bearing replacement more convenient and labor-saving. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1 Reference Figure 1 The first embodiment of the present invention provides a bearing replacement device for synchronous oiling during bearing installation, including an inner hole puller 100. The inner hole puller 100 includes a rotating shaft 101 and a fixed outer shaft 102. The rotating shaft 101 is threaded inside the fixed outer shaft 102, and the rotating shaft 101 is electrically connected to a motor 103. The oiling unit 200 includes a sliding ring 201, which is sleeved on the fixed outer shaft 102 and can slide up and down along the fixed outer shaft 102. When a brush 201a is provided on one side of the sliding ring 201, when the sliding ring 201 slides to the bottom, the brush 201a can contact the bearing and play the role of spreading lubricating oil evenly on the bearing body 300.

[0025] Furthermore, the fixed outer shaft 102 is equipped with two rotating rods 102d at one end where the cylinder 102c is located. An inner support hook 102e is rotatably mounted on the rotating rod 102d. A handle 101b is also mounted on the rotating shaft 101, and the handle 101b rotates circumferentially on the rotating shaft 101.

[0026] A shrinkage ring 301 is fitted inside the bearing body 300. The shrinkage ring 301 has an opening and closing groove 301a, which provides a space for the shrinkage ring 301 to deform under external force. An asbestos wall 301b is provided on the outer wall of the shrinkage ring 301. The asbestos wall 301b has a large frictional force, which can provide sufficient friction to carry the bearing body 300 out, preventing slippage during bearing disassembly due to insufficient friction between the rotating shaft 101 and the inner wall of the bearing body 300. The bearing body 300 is made of a tough material, and it can return to its original shape after deformation and loss of external force.

[0027] During the process of separating and disassembling the bearing and bearing column using the bearing replacement equipment, firstly, align the bottom end of the rotating shaft 101 with the inside of the bearing column and hold it in place. Then, insert the end of the inner support hook 102e into the inner hole of the bearing, ensuring that the inner support hook 102e clamps the outer ring of the bearing and securely fixes it. Start the motor 103 to drive the rotating shaft 101 to rotate forward. The thread of the rotating shaft 101 rotates inside the fixed outer shaft 102 with which it is threaded and slides downward. When the rotating shaft 101 slides downward into the opening at the larger end of the shrink ring 301, because the lower end of the shrink ring 301 is smaller, the rotating shaft 101 supports the lower end of the shrink ring 301. Open the bearing body 300 so that the outer surface of the shrink ring 301 is in close contact with the inner wall of the bearing body 300. At this time, the friction between the inner wall of the bearing body 300 and the shrink ring 301 is large enough. Since the rotating shaft 101 is fixed at this time, its position relative to the bearing body 300 is stationary. Therefore, the motor 103 is reversed at this time. The reverse rotation of the rotating shaft 101 causes the fixed outer shaft 102 to move upward relative to the rotating shaft 101. Since the bearing body 300 is tightly fixed by the inner support hook 102e, it is hooked by the upward sliding fixed outer shaft 102 and moves relative to the bearing column, and is pulled upward. The bearing body 300 is then separated from the bearing column and disassembled.

[0028] After the bearing body 300 is disassembled, the forward rotation motor 103 causes the rotating shaft 101 to slide upward. After the rotating shaft 101 is disengaged from the shrink ring 301, the shrink ring 301 automatically resets due to its own toughness, ending the clamping and limiting of the bearing body 300. The inner support hook 102e is then removed from the bearing body 300, allowing the disassembled bearing body 300 to fall off the inner hole puller 100.

[0029] Example 2 Reference Figure 7 Compared to Embodiment 1, this embodiment differs from the first embodiment in that: the other side of the sliding ring 201 is also provided with a sinking component 202.

[0030] Furthermore, the sinking component 202 includes a ring seat 202a and three sets of connecting shafts 202b. Each end of the connecting shaft 202b is provided with a ball 202a-2. The ball 202a-2 is fitted inside the universal ball seat 202a-1 and can rotate inside the universal ball seat 202a-1 without falling off. The universal ball seats 202a-1 at both ends of the same connecting shaft 202b are fixed on the surfaces of the ring seat 202a and the sliding ring 201 respectively.

[0031] The ring seat 202a has an annular insertion groove M. The rotating shaft 101 is fixedly mounted with an insertion bracket 101a. The outer ring of the insertion bracket 101a is an annular driven ring 101a-1, which is fitted into the insertion groove M.

[0032] The outer circumference of the insertion slot M is provided with several sets of receiving spaces N, and the driven coil 101a-1 is provided with several sets of rebound plates 101a-2; a magnet is embedded in the end of the rebound plate 101a-2, and a magnet is also embedded in the corresponding position inside the driven coil 101a-1. The number of rebound plates 101a-2 is the same as the number of receiving spaces N; the diameter of the insertion slot M is slightly larger than the diameter of the rotating shaft 101.

[0033] The fixed outer shaft 102 is provided with a plurality of guide grooves 102a along the long axis of the outer wall, and the fixed outer shaft 102 is provided with an annular rotating groove 102b along the circumferential direction of the outer wall. The end of the guide groove 102a away from the motor 103 is connected to the rotating groove 102b. The inner wall of the sliding ring 201 is provided with a guide block 201c, which is slidably disposed in the guide groove 102a.

[0034] Furthermore, the bearing replacement equipment that synchronously lubricates the bearing during installation also includes a bearing body 300, and a cylinder 102c is fixedly installed at the end of the fixed outer shaft 102 away from the motor 103, with the cylinder 102c abutting against the bearing body 300.

[0035] During the process of separating and disassembling the bearing and bearing column using the bearing replacement equipment, firstly, align the bottom end of the rotating shaft 101 with the inside of the bearing column and hold it in place. Then, insert the end of the inner support hook 102e into the inner hole of the bearing, ensuring that the inner support hook 102e clamps the outer ring of the bearing and is firmly fixed. Start the motor 103 to drive the rotating shaft 101 to rotate forward. The thread of the rotating shaft 101 rotates inside the fixed outer shaft 102 that is threadedly connected to it and slides downward. When the rotating shaft 101 slides downward to the opening at the larger end of the shrink ring 301, because the lower end of the shrink ring 301 is smaller, the rotating shaft 101 opens the lower end of the shrink ring 301, so that the outer surface of the shrink ring 301 is in close contact with the inner wall of the bearing body 300. At this time, the friction between the inner wall of the bearing body 300 and the shrink ring 301 is large enough. When the rotating shaft 101 rotates clockwise, it drives the driven ring 101a-1 to rotate clockwise, which rotates clockwise within the insertion slot M. The rebound piece 101a-2 overcomes its own elasticity and sticks tightly to the rebound piece 101a-2 under the contraction of the insertion slot M. Since the magnets inside the rebound piece 101a-2 and the driven ring 101a-1 attract each other, the rebound piece 101a-2 will not rebound after it sticks tightly to the driven ring 101a-1. The driven ring 101a-1 can continue to rotate clockwise with the rotating shaft 101 within the insertion slot M.

[0036] Since the rotating shaft 101 is fixed at this time and its position relative to the bearing body 300 is stationary, the motor 103 is reversed at this time. The reverse rotation of the rotating shaft 101 causes the fixed outer shaft 102 to move upward relative to the rotating shaft 101. Since the bearing body 300 is tightly fixed by the inner support hook 102e, it is hooked by the upward sliding fixed outer shaft 102, and moves relative to the bearing column, and is pulled upward. The bearing body 300 is then separated from the bearing column and disassembled. When the rotating shaft 101 reverses, since the rebound plate 101a-2 is in close contact with the driven ring 101a-1, it also reverses with the rotating shaft 101 and can freely rotate counterclockwise in the insertion slot M. The reverse rotation of the rotating shaft 101 will not cause the ring seat 202a to rotate synchronously, so it will not trigger the coupling 202b to rotate. At this time, the sinking component 202 will not rotate with the rotating shaft 101 and will not be triggered. The brush 201 will not descend to contact the bearing. Since it is not necessary to apply lubricating oil to the bearing when it is disassembled, it can be ensured that the sinking component 202 will not interfere with the disassembly process when the bearing is disassembled.

[0037] During the installation of bearings and bearing posts using bearing replacement equipment, the new bearing is first heated in an electromagnetic heater. After heating, the end of the inner support hook 102e is inserted into the inner hole of the bearing, ensuring that the inner support hook 102e clamps the outer ring of the bearing and securely fixes it. The new bearing body 300 is lifted by holding the handle 101b, and the inner wall of the bearing body 300 is aligned with the bearing post to be installed. The cylinder 102c is aligned with the bearing body 300, and the cylinder 102 is activated to push the new bearing body 300 onto the bearing post to be installed. At this time, the motor 103 is started, causing it to reverse, and the rotating shaft 101 reverses. Since there is no forward rotation, the rebound plate 101a-2 is not pressed tightly against the driven ring 101a-1. In operation, the rebound piece 101a-2 is in the open state and located in the accommodating space N. The motor 103 reverses, causing the rotating shaft 101 to reverse. The open rebound piece 101a-2 will push the ring seat 202a to rotate counterclockwise synchronously. Since the plug-in bracket 101a is fixed on the rotating shaft 101, and the plug-in bracket 101a can limit the vertical displacement of the ring seat 202a, when the ring seat 202a rotates counterclockwise, the connecting shaft 202b is powered to slowly change from an inclined state to a vertical state. The ball 202a-2 can rotate at any angle within the universal ball seat 202a-1. The universal ball seat 202a-1 and the ball 202a-2 provide a limiting mechanism for the connecting shaft 202b, which can rotate arbitrarily.

[0038] Because the sliding ring 201 is restricted by the guide groove 102a provided along the long axis of the outer wall of the fixed outer shaft 102, it can only move up and down along the fixed outer shaft 102. Therefore, when the ring seat 202a rotates counterclockwise, during the process of the connecting shaft 202b changing from an inclined state to a vertical state, the distance between the ring seat 202a and the sliding ring 201 is gradually expanded under the change of the connecting shaft 202b. The sliding ring 201 descends along the fixed outer shaft 102. When the sliding ring 201 descends to the bottom of the guide groove 102a, it slides into the rotating groove 102b. The sliding ring 201 can rotate horizontally along the rotating groove 102b. Even if the ring seat 202a continues to rotate counterclockwise, the sliding ring 201 will rotate counterclockwise synchronously with the ring seat 202a because it is freed from the vertical displacement limit of the guide groove 102a. When the sliding ring 201 descends to the bottom of the guide groove 102a, the brush 201a contacts the bearing and lubricating oil is applied to the brush 201a. The brush 201a rotates synchronously with the sliding ring 201, realizing the oiling process of the bearing body 300.

[0039] The remaining structures are the same as those in Example 1.

[0040] Example 3 Reference Figures 1-7In the third embodiment of the present invention, an oil storage cavity Q is further provided inside the sliding ring 201. The material of the sliding ring 201 above the oil storage cavity Q can be a transparent material. Preferably, it can be set as an openable cover, so that the staff can observe the amount of lubricating oil inside the oil storage cavity Q in time so as to replenish the lubricating oil in time.

[0041] A cover 201b is slidably installed inside the oil storage cavity Q. The diameter of the cover 201b should be larger than the diameter of the oil storage cavity Q. The cover 201b slides to the opening of the oil storage cavity Q to seal the oil storage cavity Q. The cover 201b is fixed to the inner wall of the oil storage cavity Q by a spring 201b-1. A brush 201a is fixedly installed on the cover 201b.

[0042] The function of spring 201b-1 is to reset the cover 201b and improve the sealing effect with the oil storage cavity Q.

[0043] The surface of the brush 201a shaft is provided with spiral grooves, and its surface tension can control the flow rate of the flowing oil. The material of the brush 201a is preferably made of a bristle density with a large surface tension, which can make the lubricating oil hang more firmly on the bristles and avoid excessive lubricating oil flowing out and causing waste.

[0044] During the installation of bearings and bearing posts using bearing replacement equipment, the new bearing is first heated in an electromagnetic heater. After heating, the end of the inner support hook 102e is inserted into the inner hole of the bearing, ensuring that the inner support hook 102e clamps the outer ring of the bearing and securely fixes it. The new bearing body 300 is lifted by holding the handle 101b, and the inner wall of the bearing body 300 is aligned with the bearing post to be installed. The cylinder 102c is aligned with the bearing body 300, and the cylinder 102 is activated to push the new bearing body 300 onto the bearing post to be installed. At this time, the motor 103 is started, causing it to reverse, and the rotating shaft 101 reverses. Since there is no forward rotation, the rebound plate 101a-2 is not pressed tightly against the driven ring 101a-1. In operation, the rebound piece 101a-2 is in the open state and located in the accommodating space N. The motor 103 reverses, causing the rotating shaft 101 to reverse. The open rebound piece 101a-2 will push the ring seat 202a to rotate counterclockwise synchronously. Since the plug-in bracket 101a is fixed on the rotating shaft 101, and the plug-in bracket 101a can limit the vertical displacement of the ring seat 202a, when the ring seat 202a rotates counterclockwise, the connecting shaft 202b is powered to slowly change from an inclined state to a vertical state. The ball 202a-2 can rotate at any angle within the universal ball seat 202a-1. The universal ball seat 202a-1 and the ball 202a-2 provide a limiting mechanism for the connecting shaft 202b, which can rotate arbitrarily.

[0045] Because the sliding ring 201 is restricted by the guide groove 102a provided along the long axis of the outer wall of the fixed outer shaft 102, it can only move up and down along the fixed outer shaft 102. Therefore, when the ring seat 202a rotates counterclockwise, during the process of the connecting shaft 202b changing from an inclined state to a vertical state, the distance between the ring seat 202a and the sliding ring 201 is gradually expanded under the change of the connecting shaft 202b. The sliding ring 201 descends along the fixed outer shaft 102. When the sliding ring 201 descends to the bottom of the guide groove 102a, it slides into the rotating groove 102b. The sliding ring 201 can rotate horizontally along the rotating groove 102b. Even if the ring seat 202a continues to rotate counterclockwise, the sliding ring 201 will rotate counterclockwise synchronously with the ring seat 202a because it is freed from the vertical displacement limit of the guide groove 102a. When the sliding ring 201 descends to the bottom of the guide groove 102a, the brush 201a contacts the bearing body 300. The brush 201a and the bearing body 300 are squeezed together, and the brush 201a will move upward. At this time, the cover 201b is lifted by the brush 201a, and a gap is created between the cover 201b and the opening of the oil storage cavity Q. The lubricating oil stored in the oil storage cavity Q will flow out along the gap between the opening of the oil storage cavity Q and the cover 201b under the action of gravity, and fall onto the bristles of the brush 201a along the rod of the brush 201a. The oiling operation of the bearing body 300 can be automatically realized without the need for additional operation by the operator. After the operator visually inspects the grease application and confirms it is even, the motor 103 is stopped, and the inner support hook 102e is removed from the bearing body 300, allowing the disassembled bearing body 300 to fall off the inner hole puller 100. The brush 201a is no longer pressed against the bearing body 300, and the cover 201b, under the action of the spring 201b-1, re-covers the opening of the oil reservoir Q, sliding to seal the oil reservoir Q.

[0046] The remaining structure is the same as that in Example 3.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
