[0001] The utility model belongs to the technical field of wind turbine gear rings, in particular to an assembled wind turbine gear ring which is easy to disassemble. Background Art

[0002] In the field of wind power, the ring gear is a key component of the wind turbine transmission system. Its performance and life directly affect the stability and economy of the entire wind power system. The ring gear, especially the large ring gear that meshes with the gearbox input shaft, is prone to wear, pitting and even breakage under the long-term cyclic load and environmental erosion during the operation of the wind turbine. Once these problems occur, they not only reduce the transmission efficiency, but may also cause failure of the entire transmission chain, thereby affecting the normal operation of the wind turbine. For the traditional one-piece ring gear design, once a tooth on the ring gear is worn to an unusable state, the usual solution is to replace the entire ring gear. This approach is not only complicated to operate, but also requires shutdown and disassembly of a large number of connecting parts, which greatly increases the time and difficulty of maintenance operations, and also significantly increases maintenance costs. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides an assembled wind turbine gear ring that is easy to disassemble, which solves the problem that a certain tooth on the gear ring is worn to an unusable state. The usual solution is to replace the entire gear ring. This approach is complicated to operate, greatly increases the time and difficulty of maintenance operations, and also significantly increases the maintenance cost.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled wind turbine gear ring that is easy to disassemble, comprising a connecting shaft, a gear ring is provided on one side of the connecting shaft, a plurality of mounting grooves are opened on the inner wall of the gear ring, the mounting groove is I-shaped, and a connecting block one is fixedly installed in the inner wall of the gear ring in the mounting groove, and the number of the connecting blocks one is the same as the number of the mounting grooves, two mounting blocks are slidably connected in the mounting groove, the size of the two mounting blocks is the same as the size of the mounting groove, a connecting block two is provided between the two mounting blocks, a bolt is threadedly connected to one side of the connecting block two, teeth are fixedly connected to the lower part of the two mounting blocks, and one side of the connecting block two is connected to one side of the teeth.

[0005] As a further solution of the utility model: a plurality of fixed blocks are fixedly connected to the outer wall of the gear ring, and a rotating shaft is rotatably connected between two corresponding fixed blocks.

[0006] As a further solution of the utility model: a screw is fixedly connected to one side of the rotating shaft, one end of the screw is fixedly connected to a limiting plate, and the outer wall of the screw is threadedly connected to a rotating wheel.

[0007] As a further solution of the utility model: a plurality of clamping blocks are fixedly connected to the outer wall of the connecting shaft, and the positions of the clamping blocks are opposite to the positions of two adjacent fixed blocks.

[0008] As a further solution of the utility model: a clamping groove is provided on one side of the clamping block, and the height of the clamping groove is the same as the diameter of the screw.

[0009] As a further solution of the utility model: the bolt passes through the connecting block 1, and the bolt and the connecting block 1 are threadedly connected.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The assembled wind turbine gear ring that is easy to disassemble is provided with an installation groove, a connecting block 1, an installation block, a connecting block 2, bolts and teeth. During the long-term use of the teeth, when a group of teeth needs to be replaced, the bolts are rotated, and the bolts rotate on the inner walls of the connecting block 1 and the connecting block 2. After the bolts are separated from the connecting block 1 and the connecting block 2, the installation block drives the teeth to slide in the installation groove and can be removed. In this way, not only the firmness of the teeth is guaranteed during the use of the teeth, but also when the teeth are damaged, there is no need to replace the entire gear ring, which is easy to operate and reduces the maintenance cost.

[0012] 2. The assembled wind turbine gear ring which is easy to disassemble is provided with a fixed block, a rotating shaft, a screw, a rotating wheel, a clamping block and a clamping groove. When the gear ring needs to be maintained, the rotating wheel is rotated, and the rotating wheel rotates on the outer wall of the screw to release the squeezing of the clamping block on the outer wall of the connecting shaft. Then the screw and the rotating wheel are driven by the rotating shaft to rotate between the two corresponding fixed blocks, so that the screw is disengaged from the clamping groove on the clamping block. In this way, the gear ring is convenient to be removed, so that the gear ring can be maintained or replaced, thereby improving the practicality of the wind turbine gear ring.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-5 As shown, the utility model provides a technical solution: an assembled wind turbine gear ring that is easy to disassemble, including a connecting shaft 1, a gear ring 2 is provided on one side of the connecting shaft 1, and a plurality of mounting grooves 3 are opened on the inner wall of the gear ring 2, and the mounting groove 3 is I-shaped. The adoption of the I-shaped mounting groove 3 allows the mounting block 5 to be firmly installed in the mounting groove 3, ensuring the stability of the teeth 8 of the gear ring 2 when the gear ring 2 rotates at high speed, avoiding the loosening of components caused by vibration, thereby extending the service life of the gear ring 2, and the inner wall of the gear ring 2 is located in the mounting groove 3 and fixedly installed with a connecting block 4, and the number of the connecting blocks 4 is equal to the number of the mounting grooves 3. The amount is the same, and there are two mounting blocks 5 slidingly connected in the mounting groove 3. The size of the two mounting blocks 5 is the same as that of the mounting groove 3. A connecting block 2 6 is provided between the two mounting blocks 5. A bolt 7 is threadedly connected to one side of the connecting block 2 6. The bolt 7 penetrates the connecting block 1 4. The bolt 7 is threadedly connected to the connecting block 1 4. Because the bolt 7 is provided, the connecting block 1 4 is connected to the connecting block 2 6 by the bolt 7, so that the mounting block 5 is more firmly in the mounting groove 3, and the stability of the tooth 8 when in use is improved. The teeth 8 are fixedly connected to the bottom of the two mounting blocks 5, and one side of the connecting block 2 6 is connected to one side of the tooth 8;

[0021] The outer wall of the gear ring 2 is fixedly connected with a plurality of fixed blocks 9, and a rotating shaft 10 is rotatably connected between two corresponding fixed blocks 9. Because the rotating shaft 10 is provided, after the rotating wheel 13 releases the squeezing of the clamping block 14, the rotating shaft 10 drives the screw 11 to rotate between the two corresponding fixed blocks 9, so that the screw 11 is disengaged from the clamping groove 15 on the clamping block 14, so that the gear ring 2 can be separated from the connecting shaft 1, so as to facilitate the removal of the gear ring 2. A screw 11 is fixedly connected to one side of the rotating shaft 10, and one end of the screw 11 is fixedly connected to a limiting plate 12. Because the limiting plate 12 is provided, the limiting plate 12 is used to stop the rotating wheel 13 during the rotation of the rotating wheel 13. It plays a role of limiting, preventing the rotating wheel 13 from rotating too much and disengaging from the screw 11. The outer wall of the screw 11 is threadedly connected with the rotating wheel 13. Through the cooperation between the rotating wheel 13 and the screw 11, the screw 11 is clamped in the clamping groove 15 of the clamping block 14. The rotating wheel 13 rotates on the outer wall of the screw 11 and can stably fix the gear ring 2 on one side of the connecting shaft 1 by squeezing the clamping block 14. The outer wall of the connecting shaft 1 is fixedly connected with a plurality of clamping blocks 14. The position of the clamping block 14 is opposite to the positions of the two adjacent fixed blocks 9. A clamping groove 15 is opened on one side of the clamping block 14, and the height of the clamping groove 15 is the same as the diameter of the screw 11.

[0022] The working principle of the utility model is as follows: when the tooth 8 needs to be disassembled for maintenance, by rotating the bolt 7, the bolt 7 rotates inside the connecting block 1 4 and the connecting block 2 6 to disengage from the connecting block 1 4 and the connecting block 2 6, and the mounting block 5 can drive the tooth 8 to slide and be removed in the mounting groove 3 of the gear ring 2, thereby replacing and maintaining the tooth 8. When the gear ring 2 needs to be maintained, by rotating the rotating wheel 13, the rotating wheel 13 rotates on the outer wall of the screw 11 to relax the squeezing of the clamping block 14, and then the screw 11 is driven to rotate between the corresponding two fixed blocks 9 through the rotating shaft 10 to disengage from the clamping groove 15 of the clamping block 14, so that the gear ring 2 can be removed from one side of the connecting shaft 1, thereby replacing and maintaining the gear ring 2.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
