Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a flexible coupling for wind power equipment with expandable compensation. Background Technology

[0002] In wind turbine transmission systems, flexible couplings are key components connecting the gearbox and generator shafts. They must be able to compensate for axial, radial, and angular misalignments while withstanding enormous torque and dynamic loads. Traditional flexible couplings, under extreme conditions or after long-term operation, may experience internal disengagement or "split" when displacement exceeds the design tolerances, leading to a sudden interruption of the transmission chain and rendering the coupling unusable. Therefore, this solution proposes a retractable and compensating flexible coupling for wind turbines to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a flexible coupling for wind power equipment with expandable compensation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible coupling for wind power equipment with expandable compensation, comprising:

[0005] The connector has a keyway at one end and a connector at the other end, which is used to connect the connector to the shaft.

[0006] An adjusting post is inserted and connected to one side of the connector. A spline is fixedly connected to the outer wall of the adjusting post, and the spline is inserted and connected to the inside of the keyway.

[0007] A sliding assembly is disposed on one side of a plurality of connectors opposite each other, the sliding assembly being used to limit the movement distance of the connectors.

[0008] Preferably, the connector includes a circular hole at the other end of the connector, and a limiting groove is formed on the inner wall of one side of the circular hole.

[0009] Preferably, the other end of the connector has an adjustment groove, and the middle of the connector has a tap groove.

[0010] Preferably, a first bolt is threaded through one side of the connector, and the first bolt is used to fix the shaft.

[0011] Preferably, the sliding assembly includes a sleeve plate fitted on one side of the connector, a fixing member is provided at the connection between the sleeve plate and one of the connectors, and a limiting member is provided at the connection between the sleeve plate and the other connector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1 - Figure 4 The flexible coupling for wind power equipment shown includes:

[0023] Connector 1, one end of multiple connectors 1 is provided with a keyway 101, and the other end of connector 1 is provided with a connector for connecting connector 1 and shaft body;

[0024] Adjusting post 2 is inserted and connected to one side of connector 1. Spline 201 is fixedly connected to the outer wall of adjusting post 2. Spline 201 is inserted and connected to the inside of keyway 101.

[0025] The sliding component 3 is disposed on one side opposite to the plurality of connectors 1, and the sliding component 3 is used to limit the movement distance of the connectors 1.

[0026] It should be noted that two connectors 1 are provided. A keyway 101 is provided on one side of the two connectors 1 facing each other. An adjusting post 2 is inserted and connected to the side of the connector 1 with the keyway 101. The spline 201 on the outer wall of the adjusting post 2 is inserted and connected to the inside of the keyway 101. The spline 201 and the keyway 101 restrict the adjusting post 2 from rotating on the connector 1, while the connector 1 can slide on the adjusting post 2. This design allows the length of the coupling to be adjusted flexibly. The sliding component 3 is provided at the connection point of multiple connectors 1. In use, the connector 1 is connected to the shaft to be connected. The sliding component 3 restricts the movement distance between the two connectors 1, thereby preventing the coupling from splitting and strengthening the connection between multiple shafts.

[0027] Specifically, the connector 1 includes a circular hole 102 at the other end of the connector 1, a limiting groove 103 on the inner wall of one side of the circular hole 102, an adjustment groove 104 at the other end of the connector 1, a tap groove 105 in the middle of the connector 1, and a first bolt 106 threadedly connected to one side of the connector 1 for fixing the shaft.

[0028] Furthermore, when it is necessary to fix the connector 1 to the shaft, first insert the shaft into the round hole 102 on one side of the connector 1, then pass the first bolt 106 through the connector 1, and use the first bolt 106 to press the parts on both sides of the adjusting groove 104 towards one side of the shaft, and use the first bolt 106 to fix the connector 1 to the shaft.

[0029] Specifically, the sliding component 3 includes a sleeve plate 303 sleeved on one side of the connector 1. A fixing member 4 is provided at the connection between the sleeve plate 303 and one of the connectors 1. A limiting member is provided at the connection between the sleeve plate 303 and the other connector 1. The limiting member includes a groove 301 formed on the outer wall of the other connector 1. A slider 302 is fixedly connected to the side of the sleeve plate 303 near the connector 1. The slider 302 is inserted into the inside of the groove 301.

[0030] It should be noted that the cross-section of the sleeve 303 is set to be semi-arc. When in use, it is sleeved on one side of the connector 1. There are two sleeves 303, which are sleeved at the connection of the two connectors 1. The two sleeves 303 are fixedly connected to the two connectors 1 respectively. Before fixing the sleeve 303 to the connector 1, the slider 302 is inserted into the slide groove 301. The slide groove 301 restricts the movement distance of the slider 302, and the slider 302 restricts the movement distance of the sleeve 303 and the connector 1.

[0031] Specifically, the fastener 4 includes a threaded groove 401 formed on the outer wall of the connector 1, and a second bolt 402 is provided at the connection between the sleeve 303 and one of the connectors 1.

[0032] It should be noted that when the sleeve 303 needs to be fixed to the connector 1, the threaded hole on the sleeve 303 is used to fix the sleeve 303 to the connector 1. The sleeve 303 is then placed on the connector 1 and the second bolt 402 is passed through the sleeve 303 and the threaded groove 401 in sequence. The position of the sleeve 303 is fixed by the second bolt 402.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
