[0002] In the design and manufacture of wind turbine bearings, circlips are a key fastener that primarily limits the axial movement of the bearing. Circlips are typically made of a material with a certain degree of elasticity, such as spring steel. During installation, the circlips need to be stretched out and placed on the bearing, then restored to their original shape to secure the bearing. For wind turbine bearings with larger diameters, larger circlips are required.

DETAILED DESCRIPTION

[0021] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0022] See also Figure 1 The embodiment of the present application provides a disassembly and assembly tool 100, including two movable parts 1, an active part 2 and a passive part 3. The two movable parts 1 are both movably connected to the active part 2, and the passive part 3 is transmission-connected to the active part 2. The two ends of the passive part 3 away from the active part 2 are respectively connected to the movable parts 1. The active part 2 is used to be driven to move the passive part 3 relative to the active part 2, so that the passive part 3 pushes the two movable parts 1 to close or unfold. The two movable parts 1 of the disassembly and assembly tool 100 are respectively extended into the corresponding retaining spring holes. The active part 2 can be driven to move the passive part 3 relative to the active part 2 so that the two movable parts 1 are away from each other. The active part 2 transmits the driving force to the passive part 3, and the passive part 3 can amplify the driving force by mechanical transmission and transmit the amplified force to the two movable parts 1, thereby providing sufficient operating force for the movable part 1 to open the retaining spring, so that the retaining spring can be opened to be fixed on the bearing, thereby reducing the difficulty of installing the retaining spring.

[0023] In an optional embodiment, the active member 2 may be driven electrically or manually.

[0024] In an optional embodiment, the transmission method of the active member 2 and the driven member 3 can be a screw transmission, a rack and pinion transmission, a sprocket chain transmission, or a cam transmission. When the transmission method of the active member 2 and the driven member 3 is a screw transmission, the active member 2 is a screw rod 21, and the driven member 3 is also provided with a thread that engages with the screw rod 21. When the transmission method of the active member 2 and the driven member 3 is a rack and pinion transmission, the active member 2 is a gear and the driven member 3 is a component provided with a rack. When the transmission method of the active member 2 and the driven member 3 is a sprocket chain transmission, the active member 2 is a sprocket and the driven member 3 is a component provided with a chain.

[0025] See also Figure 2 In some embodiments, along the axis direction of the active member 2 (eg Figure 2 In the AA direction shown in the figure, the active member 2 is retracted relative to the movable member 1 toward the side of the driven member 3, so that there is a height difference h between the active member 2 and the movable member 1. Then, when the movable member 1 is inserted into the retaining hole on the retaining spring, the active member 2 can avoid contacting the retaining spring body, thereby preventing the retaining spring body from interfering with the drive of the active member 2.

[0026] See also Figure 1 In some embodiments, the disassembly and assembly tool 100 further includes a fixing member 4, to which one end of each of the two movable members 1 is movably connected, and the active member 2 is rotatably connected. The fixing member 4 can support the movable members 1 and the active member 2. When the active member 2 is driven and the driven member 3 pushes the movable member 1 to move, the fixing member 4 can withstand the resulting reaction force, ensuring that the entire tool does not shake or move during operation.

[0027] See also Figure 2In some embodiments, the fixing member 4 includes a first portion 41 and a second portion 42 connected to each other. The first portion 41 is rotatably connected to the active member 2, and the second portion 42 is provided on both sides of the first portion 41. Figure 2 In the BB direction shown in FIG, the second portion 42 is inclined relative to the first portion 41 toward one side of the follower 3, and the first direction (as shown in FIG Figure 2 BB direction shown) and the axis direction of the active member 2 (as shown Figure 2 The second portion 42 intersects the fixed member 4 in the direction AA shown, and the second portion 42 is movably connected to one end of the corresponding movable member 1. Providing the second portion 42 to the fixed member 4 increases the length of the fixed member 4 along the first direction, thereby providing space for the connection of the movable member 1. Furthermore, providing the second portion 42 improves the flexibility of the movable member 1. Alternatively, the movable connection may be a hinged joint or a ball joint.

[0028] See also Figure 2 In some embodiments, the active member 2 is a screw 21, and the surface of the screw 21 is provided with a first thread, see Figure 3 The fixing member 4 is provided with a first mounting hole 411, the follower 3 is provided with a second mounting hole 3111, the second mounting hole 3111 is provided with a second thread, the screw 21 is provided in the first mounting hole 411 and the second mounting hole 3111, the screw 21 is at least partially located outside the first mounting hole 411, the screw 21 is rotatably connected to the first mounting hole 411, and the screw 21 is threadedly connected to the second mounting hole 3111 through the first thread and the second thread. When the screw 21 rotates, due to the action of the thread, the follower 3 will move along the axial direction of the screw 21. The rotation of the screw 21 can be achieved by manual or electric tools, and the operation is simple. The operator only needs to rotate the screw 21 to control the movement of the follower 3, which can facilitate the closing or expansion of the movable part 1. Furthermore, the transmission through the screw 21 can withstand a large axial force, so that the follower 3 can effectively push the movable part 1 to expand or close.

[0029] It is understandable that the screw rod 21 is at least partially located outside the first mounting hole 411 to reserve a section for an operator to apply a driving force to the screw rod 21 to rotate the screw rod 21 .

[0030] It should be noted that the first mounting hole 411 is not provided with threads, so that the screw rod 21 can rotate freely in the first mounting hole 411 .

[0031] See also Figure 2In some embodiments, the screw 21 includes a screw portion 211 and a cap portion 212 connected to each other. The surface of the screw portion 211 is provided with a first thread. The screw portion 211 is inserted into the first mounting hole 411 and the second mounting hole 3111. The screw portion 211 is rotatably connected to the first mounting hole 411 and is threadedly connected to the second mounting hole 3111. The cap portion 212 is located outside the first mounting hole 411 and on the side of the fixing member 4 facing away from the driven member 3. The outline size of the cap portion 212 is larger than the outline size of the first mounting hole 411. The screw portion 211 is provided on the screw 21 to provide a force application point, making it easier to rotate the screw 21. The operator can clamp the cap portion 212 with a hand tool (wrench) or an electric tool, thereby facilitating the rotation of the screw 21, thereby driving the driven member 3 to move and realizing the expansion or closure of the movable member 1. The larger size of the cap 212 can increase the contact area with the hand tool or power tool, thereby improving the torque transmission efficiency. This makes it easier to overcome resistance when installing or removing a larger size retaining ring, ensuring the smooth rotation of the screw 21. The outline size of the cap 212 is larger than the outline size of the first mounting hole 411, which can prevent the screw 21 from being over-inserted into the fixing part 4 during the installation process. When the cap 212 contacts the fixing part 4, it indicates that the screw 21 has been inserted into the correct position, avoiding installation problems or damage to the fixing part 4 caused by the screw 21 being inserted too deep. By limiting the insertion of the screw 21, the cap 212 can help ensure that the threaded connection between the screw 21 and the follower 3 is in the correct position, thereby ensuring the accuracy and reliability of the transmission.

[0032] See also Figure 2 In some embodiments, the disassembly and assembly tool 100 further includes a limiting member 5, which is provided with a third mounting hole (not shown in the figure). The screw 21 is passed through the third mounting hole. The limiting member 5 is fixed to the screw 21 and is located on the side of the fixing member 4 close to the driven member 3. Since the limiting member 5 is fixed to the screw 21, it can limit the screw 21 and prevent the screw 21 from moving relative to the fixing member 4 in a direction away from the driven member 3, thereby improving the stability of the overall structure of the disassembly and assembly tool 100. Optionally, the limiting member 5 can be a nut or a threaded sleeve. When the limiting member 5 is a nut, the connection between the nut and the screw portion 211 of the screw 21 is: it neither interferes with the rotation of the screw portion 211 nor causes the nut to detach from the screw portion 211.

[0033] See also Figure 2 and Figure 3 In some embodiments, the first portion 41 of the fixing member 4 defines a first mounting hole 411 , the screw portion 211 of the screw rod 21 is rotatably connected to the first portion 41 of the fixing member 4 , and the cap portion 212 of the screw rod 21 is located on a side of the first portion 41 of the fixing member 4 that is away from the driven member 3 . The stopper 5 is located on a side of the first portion 41 of the fixing member 4 that is closer to the driven member 3 .

[0034] See also Figure 2 In some embodiments, the follower 3 includes a slide 31 and two push rods 32. The slide 31 is transmission-connected to the active member 2, and the two push rods 32 are arranged on both sides of the slide 31. One end of each push rod 32 is movably connected to the slide 31, and the other end is movably connected to the corresponding movable member 1. The push rod 32 is movably connected to the slide 31 and the movable member 1, which can improve the structural flexibility of the follower 3. The movable connection allows the push rod 32 to freely adjust its angle and position within a certain range, thereby adapting to the different trajectories and angle changes that may occur in the slide 31 and the movable member 1 during movement. If the push rod 32 is fixedly connected to the slide 31 and the movable member 1, stress concentration may occur due to angle changes during movement, resulting in damage to the push rod 32. The movable connection can disperse stress, reduce the wear and damage risk of components, and extend the service life of the tool. The movable connection makes installation of the push rod 32 easier. During installation, there is no need to precisely align the push rod 32 with the fixed position. The push rod 32 can be connected to the slide 31 and the movable part 1 by adjusting the angle and position of the movable connection, thereby improving installation efficiency and reducing the possibility of installation errors. The movable connection can reduce friction loss between the push rod 32, the slide 31 and the movable part 1, thereby improving transmission efficiency. Because the push rod 32 can freely adjust its position within a certain range, it can better cooperate with the slide 31 and the movable part 1, reducing frictional resistance and making power transmission smoother. In an optional embodiment, the movable connection can be a hinged joint or a ball joint.

[0035] See also Figure 2 In some embodiments, the slide 31 includes a third portion 311 and a fourth portion 312 connected to each other, the third portion 311 is transmission-connected to the active member 2, and the fourth portion 312 is disposed on both sides of the third portion 311, along the first direction (such as Figure 2 BB direction), the fourth portion 312 is inclined relative to the third portion 311 toward the side of the fixing member 4, and the first direction is in the direction of the axis of the active member 2 (as shown in FIG. Figure 2 The fourth portion 312 is rotatably connected to the corresponding push rod 32. The third portion 311 is directly connected to the active member 2 and can receive power from the active member 2. The fourth portion 312 is located on both sides of the first portion 41 and is tilted toward the fixed member 4 relative to the third portion 311 along the first direction. The fourth portion 312 can more reasonably distribute the force transmitted from the active member 2 to the push rods 32 on both sides, and can also make the movement of the push rods 32 more flexible. In an alternative embodiment, the movable connection can be a hinge or a ball joint.

[0036] See also Figure 2 and Figure 3In some embodiments, a second mounting hole 3111 is formed through the third portion 311 of the slide 31 , and the third portion 311 of the slide 31 is threadedly connected to the screw portion 211 of the screw rod 21 .

[0037] See also Figure 2 In some embodiments, each movable member 1 includes a fifth portion 11 and a sixth portion 12. The fifth portion 11 includes a first end 111 and a second end 112 along its length. The first end 111 is movably connected to the active member 2, and the second end 112 is movably connected to the active member 2 along the first direction (such as Figure 2 BB direction shown) is inclined relative to the first end 111 toward the side away from the active member 2, and the first direction is consistent with the axial direction of the active member 2 (as shown Figure 2 The movable part 1 intersects with the AA direction shown in the figure, the fifth part 11 is movably connected to one side of the corresponding follower 3, the sixth part 12 is bent and connected to the second end 112 of the fifth part 11, and the sixth part 12 extends along the axial direction of the active part 2. In an optional manner, the movable connection may be a hinge or a ball head connection. The sixth part 12 extends along the axial direction of the active part 2, which can facilitate docking with the retaining hole of the retaining spring. The inclined portion at the upper end of the movable part 1 can form an angle with the follower 3, so that the follower 3 can more effectively transmit force to the movable part 1 when it moves. This force transmission method can improve the efficiency of the operation, so that the movable part 1 can respond to the movement of the follower 3 more quickly, thereby realizing the rapid installation or disassembly of the retaining spring.

[0038] See also Figure 2 In some embodiments, the fifth portion 11 of the movable member 1 is movably connected to the second portion 42 of the fixed member 4 , and the fifth portion 11 of the movable member 1 is movably connected to the push rod 32 of the driven member 3 .

[0039] See also Figure 2 In some embodiments, the bottom surface of the sixth portion 12 of the movable member 1 is along the axis direction of the active member 2 (eg Figure 2 A pliers head 13 is protruded (in the AA direction shown), and the pliers head 13 is used to be inserted into the clamping hole of the clamping spring.

[0040] See also Figure 2 In some embodiments, the two movable members 1, the driven member 3 and the fixed member 4 are all aligned with the axis of the active member 2 (eg Figure 2 Thus, the disassembly and assembly tool 100 is symmetrically arranged as a whole, which can ensure that the driving force on the two movable parts 1 is consistent, so that the disassembly and assembly tool 100 can open the retaining spring with more uniform and stable force.

[0041] In some embodiments, the disassembly and assembly tool 100 of the present application is used as follows: the pliers 13 on the two movable parts 1 are respectively inserted into the two retaining holes of the retaining ring, and then the motor wrench is used to rotate the cap 212 on the screw 21 of the active part 2, causing the screw 211 to rotate, thereby driving the slide 31 of the driven part 3 to drive the push rod 32 upward, causing the push rod 32 to push the movable part 1 to expand, and the two movable parts 1 to expand the retaining ring. The expanded retaining ring is then placed on the bearing, completing the installation of the bearing retaining ring.
