[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an assembly device for a generator rotor.
[0004] The technical solution of this utility model is as follows: it includes a generator rotor, a frame, a rotating rod, a connecting seat, and a movable seat. The generator rotor includes a first rotor and a second rotor. A first support seat and a second support seat are mounted on the frame. The first support seat is located to the left of the second support seat. The second support seat is provided with a first connecting member connected to the first rotor. A horizontally arranged rotating rod is rotatably mounted on the first support seat, and a portion of the rotating rod is located between the first support seat and the second support seat. A connecting seat is mounted on the right end of the rotating rod. The rotating rod can rotate relative to the connecting seat. The connecting seat is provided with a second connecting member connected to the first rotor.

[0005] Furthermore, the outer wall of the rotating rod includes a first vertical wall, the connecting seat is located to the right of the first vertical wall, and a planar thrust bearing is sleeved on the rotating rod, the planar thrust bearing being located between the first vertical wall and the connecting seat. Furthermore, a deep groove ball bearing is provided between the inner wall of the connecting seat and the outer wall of the rotating rod.
[0006] Furthermore, the inner wall of the connecting seat includes a second vertical wall, and the deep groove ball bearing is located between the planar thrust bearing and the second vertical wall.
[0007] Furthermore, a first pressure cap is installed at the right end of the rotating rod to prevent the deep groove ball bearing from moving to the right. The deep groove ball bearing is located between the planar thrust bearing and the first pressure cap. An annular second pressure cap is installed at the end of the connecting seat away from the second support seat. The second pressure cap is sleeved on the outside of the planar thrust bearing. The inner diameter of the second pressure cap is smaller than the outer diameter of the deep groove ball bearing. The second pressure cap fixes the deep groove ball bearing between the second pressure cap and the second vertical wall.
[0008] Furthermore, the rotating rod includes a first connecting segment, a second connecting segment, a third connecting segment, and a fourth connecting segment connected sequentially from left to right. The first connecting segment is rotatably connected to the first support base. The second connecting segment, the third connecting segment, and the fourth connecting segment are all located to the right of the first support base. The diameter of the second connecting segment is larger than the diameter of the third connecting segment, and the diameter of the third connecting segment is larger than the diameter of the fourth connecting segment.

The first rotor can be installed on the connecting seat and the second support seat, and the second rotor can be installed on the movable seat. When the drive rotating rod rotates, the movable seat will drive the second rotor to move closer to the first rotor. During the movement, the thread between the movable seat and the rotating rod will prevent the second rotor from directly contacting the first rotor due to suction. After the second rotor has moved a certain distance, it can be fixed to the first rotor with screws, thereby realizing the assembly of the first rotor and the second rotor.
[0013] 2. By providing a planar thrust bearing between the first vertical wall and the connecting seat, the planar thrust bearing can axially support the rotating rod, so that even though there is a large suction force between the second rotor and the first rotor, the operator can easily drive the rotating rod to rotate.

[0021] Reference Figure 1 , 2 As shown, the generator rotor assembly device provided in the embodiment of this utility model includes a generator rotor, a frame 300, a rotating rod 400, a connecting seat 500, and a movable seat 600. The generator rotor includes a first rotor 100 and a second rotor 200. A first support seat 310 and a second support seat 320 are mounted on the frame 300. The first support seat 310 is located to the left of the second support seat 320, and the second support seat 320 has a first connecting member 321 connected to the first rotor 100. The horizontally arranged rotating rod 400 is rotatably mounted on the first support seat 310, and a portion of the rotating rod 400 is located between the first support seat 310 and the second support seat 320. Figure 3 As shown, the connecting seat 500 is mounted on the right end of the rotating rod 400, and the rotating rod 400 can rotate relative to the connecting seat 500. The connecting seat 500 has a second connecting member 510 that is connected to the first rotor 100; Figure 1 , 2As shown, the movable seat 600 is sleeved on the outside of the rotating rod 400 and threadedly connected to it. The movable seat 600 is located between the first support seat 310 and the connecting seat 500, and the movable seat 600 is connected to the second rotor 200.
[0022] like Figure 2 As shown, the first rotor 100 can be mounted on the connecting seat 500 and the second support seat 320, and the second rotor 200 can be mounted on the movable seat 600. When the drive rotating rod 400 rotates, the movable seat 600 will drive the second rotor 200 to move closer to the first rotor 100. During the movement, the thread between the movable seat 600 and the rotating rod 400 will prevent the second rotor 200 from directly contacting the first rotor 100 due to suction. After the second rotor 200 has moved a certain distance, it can be fixed to the first rotor 100 by screws, thereby realizing the assembly of the first rotor 100 and the second rotor 200.
[0023] For example, such as Figure 2 As shown, the second rotor 200 has a support column 203 on its left side. When the first rotor 100 and the second rotor 200 need to be assembled together, as... Figure 3 As shown, the left end of the first rotor 100 is connected to the second connector 510 of the connecting seat 500, as follows. Figure 5 As shown, the right end of the first rotor 100 is connected to the first connector 321 of the second support 320, as... Figure 2 As shown, the first rotor 100 is fixed between the connecting seat 500 and the second support seat 320. Since the second support seat 320 cannot rotate, the first rotor 100 and the connecting seat 500 also cannot rotate. However, since the connecting seat 500 and the rotating rod 400 are rotatably connected, the rotating rod 400 can rotate relative to the first support seat 310 and the connecting seat 500, which is equivalent to the first support seat 310 and the connecting seat 500 supporting the rotation of the rotating rod 400. Figure 8 As shown, the second rotor 200 has a hollow hole, such as Figure 2 As shown, the second rotor 200 is sleeved outside the rotating rod 400 and installed on the right side of the movable seat 600, so that the second rotor 200 is located to the left of the first rotor 100, and the second rotor 200 is located between the movable seat 600 and the connecting seat 500; then the rotating rod 400 is driven to rotate, and the rotating rod 400 rotates relative to the first support seat 310 and the connecting seat 500. During the rotation of the rotating rod 400, it drives the movable seat 600 to move to the right. Since the magnet (α) on the first rotor 100 and the magnet (β) on the second rotor 200 attract each other, the second rotor 200 and the movable seat 600 will not follow the rotation of the rotating rod 400, but can only move left and right; as Figure 4As shown, after the movable seat 600 drives the second rotor 200 to move to the right a certain distance, the second rotor 200 abuts against the support column 203 on the first rotor 100. The second rotor 200 is fixed to the support column 203 by screws, thus completing the assembly of the first rotor 100 and the second rotor 200.
[0024] Understandably, after the first rotor 100 is installed on the connecting seat 500 and the second support seat 320, the first rotor 100 will not rotate; the connecting seat 500 is used to support the rotating rod 400 and can guide the rotating rod 400 to rotate. Since the connecting seat 500 is fixed to the second support seat 320 through the first rotor 100, the connecting seat 500 also axially positions the rotating rod 400, preventing the rotating rod 400 from moving to the right; the second rotor 200 and the movable seat 600 can only move.
[0025] Furthermore, such as Figure 3 As shown, the outer wall of the rotating rod 400 includes a first vertical wall 410, the connecting seat 500 is located to the right of the first vertical wall 410, and a planar thrust bearing 700 is sleeved on the rotating rod 400, the planar thrust bearing 700 being located between the first vertical wall 410 and the connecting seat 500. By providing a first vertical wall 410 and a planar thrust bearing 700, the force on the rotating rod 400 can be sequentially transmitted to the first vertical wall 410, the planar thrust bearing 700, the connecting seat 500, the first rotor 100, and the second support seat 320. Since the rotating rod 400 is supported by the planar thrust bearing 700, there is a surface contact between the planar thrust bearing 700 and the rotating rod 400. Therefore, even though there is a large suction force between the second rotor 200 and the first rotor 100, the operator can easily drive the rotating rod 400 to rotate. In other words, by providing a planar thrust bearing 700 between the first vertical wall 410 and the connecting seat 500, the planar thrust bearing 700 can axially support the rotating rod 400, so that even though there is a large suction force between the second rotor 200 and the first rotor 100, the operator can easily drive the rotating rod 400 to rotate.
[0026] Furthermore, such as Figure 3 As shown, a deep groove ball bearing 800 is provided between the inner wall of the connecting seat 500 and the outer wall of the rotating rod 400. By providing the deep groove ball bearing 800, the rotating rod 400 rotates more smoothly.
[0027] Furthermore, such as Figure 3As shown, the inner wall of the connecting seat 500 includes a second vertical wall 520. The deep groove ball bearing 800 is located between the planar thrust bearing 700 and the second vertical wall 520, thereby fixing the planar thrust bearing 700 and the deep groove ball bearing 800 between the first vertical wall 410 and the second vertical wall 520, so that the force on the rotating rod 400 can be sequentially transmitted to the first vertical wall 410, the planar thrust bearing 700, the deep groove ball bearing 800, the connecting seat 500, the first rotor 100, and the second support seat 320.
[0028] Furthermore, such as Figure 3 As shown, a first pressure cap 420 is installed at the right end of the rotating rod 400 to prevent the deep groove ball bearing 800 from moving to the right. The deep groove ball bearing 800 is located between the planar thrust bearing 700 and the first pressure cap 420. An annular second pressure cap 530 is installed at the end of the connecting seat 500 away from the second support seat 320. The second pressure cap 530 is sleeved on the outside of the planar thrust bearing 700. The inner diameter of the second pressure cap 530 is smaller than the outer diameter of the deep groove ball bearing 800. The second pressure cap 530 fixes the deep groove ball bearing 800 between the second pressure cap 530 and the second vertical wall 520.
[0029] By providing a first pressure cap 420 and a second pressure cap 530, the deep groove ball bearing 800 is fixed between the first pressure cap 420 and the second pressure cap 530, and the deep groove ball bearing 800 and the planar thrust bearing 700 are fixed between the first vertical wall 410 and the first pressure cap 420. As a result, the planar thrust bearing 700, the deep groove ball bearing 800 and the connecting seat 500 can be pre-installed on the rotating rod 400. Each time they are assembled or disassembled, only the first rotor 100 needs to be removed.
[0030] Understandably, the inner diameter of the second cover 530 is smaller than the outer diameter of the deep groove ball bearing 800, ensuring that a portion of the second cover 530 is located on the left side of the deep groove ball bearing 800, thereby enabling the second cover 530 to fix the deep groove ball bearing 800 between the second cover 530 and the second vertical wall 520.
[0031] Furthermore, such as Figure 2 , 3 As shown, the rotating rod 400 includes a first connecting section 430, a second connecting section 440, a third connecting section 450, and a fourth connecting section 460 connected sequentially from left to right. The first connecting section 430 is rotatably connected to the first support base 310. The second connecting section 440, the third connecting section 450, and the fourth connecting section 460 are all located to the right of the first support base 310. The diameter of the second connecting section 440 is larger than the diameter of the third connecting section 450, and the diameter of the third connecting section 450 is larger than the diameter of the fourth connecting section 460. The movable seat 600 is threadedly connected to the second connecting section 440. The planar thrust bearing 700 is installed on the third connecting section 450, and the deep groove ball bearing 800 is installed on the fourth connecting section 460.
[0032] like Figure 3 As shown, since the diameter of the second connecting segment 440 is larger than the diameter of the third connecting segment 450, a first vertical wall 410 is formed between the second connecting segment 440 and the third connecting segment 450; since the diameter of the third connecting segment 450 is larger than the diameter of the fourth connecting segment 460, a third vertical wall 451 is formed between the third connecting segment 450 and the fourth connecting segment 460, and the deep groove ball bearing 800 is fixed between the third vertical wall 451 and the first pressure cap 420; the rotating rod 400 adopts the above structure, which facilitates the assembly of the planar thrust bearing 700, the deep groove ball bearing 800 and the connecting seat 500.
[0033] Furthermore, such as Figure 3 , 5 As shown, both the first connector 321 and the second connector 510 are first screws, as... Figure 6 , 7 As shown, the first rotor 100 has first mounting holes 101 on both its left and right sides, as... Figure 3 As shown, the second connector 510 is threadedly connected to the first mounting hole 101 on the left side of the first rotor 100, as... Figure 5 As shown, the first connector 321 is threadedly connected to the first mounting hole 101 on the right side of the first rotor 100.
[0034] The first rotor 100 has first mounting holes 101 on both the left and right sides. The first connector 321 and the second connector 510 are both first screws. By utilizing the first mounting holes 101 and the first connector 321 and the second connector 510 of the first rotor 100 itself, it is not necessary to redesign the first rotor 100. It is only necessary to make the first screws of the connecting seat 500 and the second support seat 320 fit with the first mounting holes 101.
[0035] Specifically, the first connector 321 is directly and rotatably mounted on the second support base 320, and the second connector 510 is directly and rotatably mounted on the connecting base 500. Alternatively, the second support base 320 may have a first hole for the first connector 321 to be inserted, and the connecting base 500 may have a second hole for the second connector 510 to be inserted. During installation, the first connector 321 passes through the first hole and is threadedly connected to the first mounting hole 101 on the right side of the first rotor 100, and the second connector 510 passes through the second hole and is threadedly connected to the first mounting hole 101 on the left side of the first rotor 100.
[0036] Specifically, there can be multiple first mounting holes 101 and first screws.
[0037] Furthermore, such as Figure 1 , 2 As shown in Figure 9, it also includes a second screw 201, and the movable base 600 is equipped with a bracket 610, as shown in Figure 9. Figure 8 , 9 As shown, the second rotor 200 is provided with a third mounting hole 202, the bracket 610 is provided with a fourth mounting hole 611, and the second screw 201 passes through the fourth mounting hole 611 and is threadedly connected to the third mounting hole 202.
[0038] The second rotor 200 is provided with a third mounting hole 202, and then the second rotor 200 itself is connected to the bracket 610 by utilizing the third mounting hole 202, so that the second rotor 200 does not need to be redesigned, but only the fourth mounting hole 611 of the bracket 610 needs to be adapted to the third mounting hole 202 of the second rotor 200.
[0039] Furthermore, a bearing (not shown in the figure) is installed between the rotating rod 400 and the first support 310, making the rotating rod 400 rotate more smoothly. Specifically, the bearing is a deep groove ball bearing.
[0040] Furthermore, such as Figure 1 , 10 As shown, a rotating wheel 470 is installed at the end of the rotating rod 400 away from the second support 320, which facilitates driving the rotating rod 400 to rotate.
