Description

Technical Field

[0001] This application relates to the technical field of wind power gearboxes, and specifically to gears for wind power gearboxes that are convenient for assembly. Background Art

[0002] With the increasing global demand for renewable energy, wind energy, as a clean and renewable energy form, has become increasingly prominent. As a key device for wind energy conversion, the performance and reliability of wind turbines directly affect the energy conversion efficiency and economic benefits. As the core component of wind turbines, the wind power gearbox undertakes the important functions of transmitting power and adjusting speed, and its performance and assembly quality are directly related to the operation stability and service life of the entire unit.

[0003] Currently, the gears in wind power gearboxes are mainly fixedly installed through multiple bolts. This traditional assembly method has exposed many problems in actual operation. Steps such as aligning and tightening the bolts one by one are cumbersome and require professional technicians for precise operation, which not only increases the assembly difficulty but also prolongs the assembly time, and is not conducive to the rapid deployment and operation of wind power equipment. In harsh outdoor environments such as strong winds, dust, and salt fog, bolt connections are prone to loosening due to factors such as vibration and corrosion, resulting in a decrease in the assembly accuracy of the gears, and further affecting the transmission efficiency and stability of the gearbox. Summary of the Utility Model

[0006] A plurality of groups of connecting members are provided on the outer surface of the inner gear ring;

[0007] Each group of connecting members includes two connecting plates, two connecting columns, two limiting rings, and two springs;

[0008] A rotating groove is opened on the outer surface of the inner gear ring, and an extrusion assembly is provided inside the rotating groove;

[0010] Through the above solution, by using the designed connecting piece in cooperation with the extrusion assembly, the rapid connection between the internal gear ring and the external planet carrier is achieved. The operator no longer needs to align and tighten bolts one by one. Only by rotating the rotating ring, under the action of the extrusion guide block and the ratchet block, the connecting column can be automatically inserted into the connecting hole of the planet carrier, greatly simplifying the assembly process, shortening the assembly time, and improving work efficiency. Since a new connection method is adopted, the loosening problem caused by factors such as vibration and corrosion during long-term use of traditional bolt connections is avoided. In addition, the fillet design at both ends of the connecting column and the limiting effect of the ratchet block further enhance the connection stability, reduce the maintenance cost caused by connection loosening, and improve the overall reliability of the wind power gearbox.

[0011] Furthermore, each of the connecting plates is fixedly connected to the outer surface of the internal gear ring, each of the connecting columns is inserted into the connecting plate close to it, each of the limiting rings is fixedly connected to the connecting column close to it, and both ends of each spring are fixedly connected to the connecting plate and the limiting ring close to it respectively.

[0012] Through the above solution, by setting the connecting column, the purpose of quickly connecting the internal gear ring and the external planet carrier can be achieved.

[0013] Furthermore, the rotating ring is rotatably connected to the rotating groove, each of the extrusion guide blocks is fixedly connected to the rotating ring, and each of the ratchet blocks is fixedly connected to the extrusion guide block.

[0014] Through the above solution, by setting the extrusion guide block, the purpose of squeezing the two connecting columns away from each other during rotation can be achieved, so that they enter the connecting holes opened in the external planet carrier.

[0015] Furthermore, the side edges of the mutually remote ends of the two concentric rings are both provided with fillets.

[0016] Through the above solution, by setting the fillets of the concentric rings, it is convenient for the internal gear ring to enter the annular groove opened in the planet carrier.

[0017] Furthermore, a plurality of handles are fixedly connected to the outer surface of the rotating ring.

[0018] Through the above solution, by setting the handles, it is convenient to rotate the rotating ring.

[0019] Furthermore, both ends of each of the connecting columns are provided with fillets.

[0020] Through the above solution, by setting the fillets at both ends of the connecting column, it is respectively convenient to enter the connecting holes opened in the external planet carrier, and at the same time convenient for the extrusion guide block to make way for extrusion.

[0021] Furthermore, the cross-section of each of the extrusion guide blocks is triangular.

[0022] With the above solution, by setting the extrusion guide block to a triangular shape, it can ensure that a group of connected columns being extruded move away from each other evenly.

[0023] Furthermore, one side of each of the ratchet blocks is set as an inclined surface, and the other side of each of the ratchet blocks is set as a straight edge.

[0024] With the above solution, through the above settings, the purpose of limiting the connected columns can be achieved.

Due to the adoption of a new connection method, it avoids the loosening problem caused by factors such as vibration and corrosion during long-term use of traditional bolt connections. In addition, the rounded corner design at both ends of the connecting columns and the limiting effect of the ratchet block further enhance the connection stability, reduce the maintenance cost caused by connection loosening, and improve the overall reliability of the wind power gearbox.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0034] Please refer to Figure 1 and Figure 2 , the gear for a wind power gearbox that is easy to assemble in this embodiment includes an inner gear ring 1. A plurality of circumferentially arranged teeth 2 are fixedly connected inside the inner gear ring 1. Concentric rings 3 are fixedly connected to both the upper surface and the bottom of the inner gear ring 1. The two concentric rings 3 and the inner gear ring 1 are on the same axis. Through the embedded fit of the concentric rings 3 with the external planet carrier, it is convenient for the gear ring and the planet carrier to be on the same axis. Rounded corners are provided at the side edges of the two ends of the two concentric rings 3 that are away from each other. Through the rounded corner setting of the concentric rings 3, it is convenient for the inner gear ring 1 to enter the annular groove opened in the planet carrier.

[0035] A plurality of groups of connecting members 4 are provided on the outer surface of the inner gear ring 1.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 , each group of connecting members 4 includes two connecting plates 401, two connecting columns 402, two limiting rings 403 and two springs 404. Each connecting plate 401 is fixedly connected to the outer surface of the inner gear ring 1. Each connecting column 402 is inserted into the connecting plate 401 close to it. Each limiting ring 403 is fixedly connected to the connecting column 402 close to it. The two ends of each spring 404 are respectively fixedly connected to the connecting plate 401 and the limiting ring 403 close to it. Through the setting of the connecting column 402, the purpose of quickly connecting the inner gear ring 1 with the external planet carrier can be achieved.

[0037] Please refer to Figure 1 , Figure 3 and Figure 4 , a rotating groove 5 is opened on the outer surface of the inner gear ring 1. An extrusion assembly 6 is provided inside the rotating groove 5. The extrusion assembly 6 includes a rotating ring 601, a plurality of extrusion guide blocks 602 and a plurality of ratchet blocks 603. The rotating ring 601 is rotatably connected to the rotating groove 5. Each extrusion guide block 602 is fixedly connected to the rotating ring 601. Each ratchet block 603 is fixedly connected to the extrusion guide block 602. Through the setting of the extrusion guide block 602, the purpose of squeezing the two connecting columns 402 away from each other during rotation can be achieved, so that they enter the connecting holes opened in the external planet carrier.

[0038] Please refer to Figure 1 , Figure 3 and Figure 4, the cross-section of each extrusion guide block 602 is triangular. By setting the extrusion guide block 602 to be triangular, it can ensure that a group of connecting columns 402 being extruded move away from each other evenly. One side surface of each ratchet block 603 is set as an inclined surface, and the other side surface of each ratchet block 603 is set as a straight edge. Through the above settings, the purpose of limiting the connecting column 402 can be achieved. A plurality of handles 7 are fixedly connected to the outer surface of the rotating ring 601. Through the setting of the handles 7, it is convenient to rotate the rotating ring 601. Both ends of each connecting column 402 are rounded. Through the rounding of both ends of the connecting column 402, it is respectively convenient to enter the connecting holes opened in the external planet carrier, and at the same time, it is convenient for the extrusion guide block 602 to make way for extrusion.

[0039] The gear for a wind power gearbox that is easy to assemble in this embodiment realizes the rapid connection between the internal gear ring 1 and the external planet carrier through the coordinated use of the designed connecting member 4 and the extrusion assembly 6. The operator no longer needs to align and tighten bolts one by one. Only by rotating the rotating ring 601, under the action of the extrusion guide block 602 and the ratchet block 603, the connecting column 402 can be automatically embedded into the connecting hole of the planet carrier, greatly simplifying the assembly process, shortening the assembly time, and improving the work efficiency. Due to the adoption of a new connection method, it avoids the loosening problem caused by factors such as vibration and corrosion during the long-term use of traditional bolt connections. In addition, the rounded design at both ends of the connecting column 402 and the limiting effect of the ratchet block 603 further enhance the stability of the connection, reduce the maintenance cost caused by connection loosening, and improve the overall reliability of the wind power gearbox.

[0040] The working principle of the above embodiment is as follows: First, place the internal gear ring 1 above the corresponding annular groove of the planet carrier to ensure that the contact surface between the concentric ring 3 and the planet carrier fits tightly, preparing for the subsequent connection. Under the action of gravity, the internal gear ring 1 and the concentric ring 3 thereon start to be preliminarily docked with the annular groove of the planet carrier. At this time, the connecting column 402 is in a free state, waiting for further extrusion operation. The operator rotates the rotating ring 601, and the rotating ring 601 applies pressure to the connecting column 402 through the extrusion guide block 602, causing the connecting column 402 to generate elastic deformation and move away from each other. As the rotating ring 601 continues to rotate, the connecting column 402 gradually enters the connecting hole opened in the planet carrier until it reaches the preset position. When the connecting column 402 completely enters the connecting hole, the ratchet block 603 plays its limiting role to prevent the connecting column 402 from withdrawing from the connecting hole due to external force, thus realizing the stable connection between the internal gear ring 1 and the planet carrier.
