Abstract
Description
Technical Field
[0001] The present invention relates to the field of mechanical transmission technology, and in particular to a gearbox support device for a wind turbine. The present invention also relates to a wind turbine gearbox assembly. Background Art
[0002] Wind turbine gearboxes require support during operation. This support primarily bears the weight and secures the gearbox in place, while also preventing vibrations from the gearbox from being transmitted to other components.
[0003] Existing support devices are generally divided into two types: internal and external. Common internal gearbox support devices typically incorporate an elastic component between the gearbox's torque arm and the movable pin to achieve vibration reduction. However, due to the compact internal structure of the gearbox, there is little space available for the elastic component to be installed. In this case, despite the elastic component's installation, the vibration reduction effect is limited. Typically, wind turbines are shortened by vibration for approximately 5-8 years.

[0026] The present invention will be further described below with reference to the accompanying drawings.
[0027] Herein, “longitudinal inner side” refers to a direction and position closer to the active core shaft in the longitudinal direction; and “longitudinal outer side” refers to a direction and position farther from the active core shaft in the longitudinal direction.
[0028] Figure 1 A gearbox support device 100 for a wind turbine according to one embodiment of the present invention (hereinafter referred to as the "support device") is schematically shown. The support device generally includes a movable core shaft 110, a frame mounting frame 120, a first elastic component 130, and a second elastic component 140. The movable core shaft 110 generally extends transversely through a connection hole 210 of a gearbox 200. Two ends of the movable core shaft 110 extend transversely from the connection hole 210 of the gearbox 200. The frame mounting frame 120 is disposed corresponding to these two ends. The frame mounting frame 120 is connected to the frame of the wind turbine. A hollow installation space 125 is formed within the frame mounting frame 120. The ends of the movable core shaft 110 extend into this installation space 125. A first elastic component 130 is disposed within this installation space 125. The first elastic component 130 is capable of surrounding the ends of the movable core shaft 110 and supporting and retaining it within the installation space 125 of the frame mounting frame 120. The middle portion of the movable core shaft 110 is held in the connecting hole 210 of the gear box 200 by being surrounded and supported by the second elastic component 140 .
[0029] exist Figures 1 to 3 In the preferred embodiment shown, the installation space 125 has a generally rectangular cross-section. The rack mounting frame 120 includes a pair of transverse frame members 121 spaced apart from each other in the longitudinal direction and a pair of longitudinal frame members 122 spaced apart from each other in the transverse direction. The transverse frame members 121 extend generally in the transverse direction and have a generally rectangular cross-section. The longitudinal frame members 122 extend generally in the longitudinal direction and have a generally rectangular cross-section. The rectangular cross-section installation space 125 is formed by the connection and encirclement of the pair of transverse frame members 121 and the pair of longitudinal frame members 122.
[0030] like Figure 3 As shown, the longitudinal frame member 122 is supported between the ends of a pair of transverse frame members 121. A longitudinally extending screw 123 passes through the longitudinal frame member 122 and the ends of the pair of transverse frame members 121, and is fastened by a nut 124, thereby effectively securing the longitudinal frame member 122 and the transverse frame member 121, thereby forming an installation space 125.
[0031] The longitudinal frame member 122 can be constructed as a solid rod. In an alternative embodiment, the longitudinal frame member 122 can also be constructed as a hollow rod to achieve cost reduction and efficiency improvement. As needed, the transverse frame member 121 can also be constructed as a hollow rod.
[0032] The transverse frame member 121 and the longitudinal frame member 122 may be made of metal.
[0033] Figures 3 to 5 A preferred structure of the first elastic component 130 is shown. The first elastic component 130 may include at least one first arc-shaped support plate 131. The first arc-shaped support plate 131 has a substantially semicircular profile. In the case where a plurality of first arc-shaped support plates 131 are provided, a plurality of (for example, 3 or more) first arc-shaped support plates 131 are concentrically or eccentrically spaced apart from each other. The at least one first arc-shaped support plate 131 is close to the end of the movable core shaft 110, wherein the first arc-shaped support plate 131 closest to the movable core shaft 110 may be in direct contact with the movable core shaft 110. For example, Figures 3 to 5 As shown, three first arc-shaped support plates 131 are provided.
[0034] The first elastic component 130 may further include at least one first planar support plate 132. The first planar support plate 132 is located longitudinally outwardly of the first curved support plate 131. The first planar support plate 132 is generally planar and can cover (or even exceed) the longitudinal projection of the first curved support plate 131.
[0035] In addition, the first elastic component 130 may further include at least one first auxiliary support plate 133. Figures 3 to 5 As shown, the at least one first auxiliary support plate 133 is disposed on both lateral sides of the first curved support plate 131 (i.e., the first curved support plate located on the outermost longitudinal side) adjacent to the first planar support plate 132. For the first auxiliary support plates 133 located on the same side of the first curved support plate 131, the plurality of first auxiliary support plates 133 are spaced apart from each other in the longitudinal direction. For the first auxiliary support plates 133 located on both sides of the first curved support plate 131, the first auxiliary support plates 133 can be symmetrically arranged relative to the first curved support plate 131.
[0036] Also like Figures 3 to 5As shown, the other areas of the first elastic component 130 are filled with a first elastic support layer 134, for example, made of rubber. That is, the first elastic support layer 134 is disposed between the first curved support plate 131 and the first planar support plate 132, between the first curved support plate 131 and the first auxiliary support plate 133, between the first planar support plate 132 and the first auxiliary support plate 133, between adjacent first curved support plates 131, between adjacent first planar support plates 132, and between adjacent first auxiliary support plates 133. The side edges of the first planar support plate 132 extend beyond the side edges of the first elastic support layer 134.
[0037] By combining the above-mentioned first arc-shaped support plate 131, first planar support plate 132, first auxiliary support plate 133 and first elastic support layer 134, a first elastic component 130 that can effectively support and reduce vibration of the movable core shaft 110 can be obtained. By providing the first planar support plate 132 and the first auxiliary support plate 133, the first elastic component 130 can have a larger variable range of stiffness in the longitudinal direction without increasing the lateral size. On the one hand, the first elastic component 130 can have sufficient stiffness to support the gearbox 200. On the other hand, the first elastic component 130 can also have sufficient deformation space to reduce the vibration of the gearbox 200 as much as possible, preventing its vibration from being transmitted to other components of the wind turbine. For gearboxes that require a compact structure, the vibration reduction of the first elastic component 130 is very effective.
[0038] In addition, if Figure 3 and Figure 5 As shown, the first planar support plate 132 and the first auxiliary support plate 133 have side edges in the transverse direction perpendicular to the axial direction of the movable core shaft. In the initial state (i.e., when not bearing a load), the side edges of the first planar support plate 132 and the first auxiliary support plate 133 are more protruding relative to the side edges of the first elastic support layer 134. When the first elastic support layer 134 is compressed and deformed due to the load, its side edges will protrude outward, and thereby further contact the first arc-shaped support plate 131, the first planar support plate 132, and the first auxiliary support plate 133 around it. This makes the overall bearing area of the first elastic component 130 increase accordingly with the increase of the load, and makes the protruding and deformed first elastic support layer 134 subject to constraints in multiple directions. This is more conducive to improving the overall fatigue performance of the first elastic component 130.
[0039] In addition, if Figure 3As shown, the first planar support plate 132 and the transverse frame member 121 can be fixedly connected by fixing screws 125. A mounting groove for receiving the first planar support plate 132 can also be provided on the surface of the transverse frame member 121 that contacts the first planar support plate 132. This effectively achieves a fixed connection between the first elastic assembly 130 and the rack mounting frame 120.
[0040] In addition, if Figures 1 to 3 As shown, the movable core shaft 110 is constructed as a rod of equal diameter. A stop plate 150 is installed on the end face of the movable core shaft 110. The stop plate 150 can be fixedly connected to the movable core shaft 110 by a stop plate screw 151. Alternatively, the stop plate 150 can be installed on the end face of the movable core shaft 110 by other appropriate means. The stop plate 150 extends radially outward so that its outer edge extends beyond the inner edge of the first elastic component 130 (that is, the inner edge of the first arc-shaped metal plate 131 at the innermost longitudinal side). In addition, a stop ring 160 is provided on the side of the first elastic component 130 facing away from the stop plate 150. The stop ring 160 is sleeved on the movable core shaft 110. A stop ring threaded hole 161 is constructed on the stop ring 160 (see Figure 7 ), a core shaft threaded hole 111 is constructed at the corresponding position of the movable core shaft 110 (see Figure 8 ). Thus, the stop ring 160 can be fixedly connected to the movable core shaft 110 via screws. The stop ring 160 extends radially outward, so that its outer edge extends beyond the inner edge of the first elastic component 130 (i.e., the inner edge of the first curved metal plate 131 located at the longitudinal innermost side). Thus, the axial position of the first elastic component 130 relative to the movable core shaft 110 can be fixed by the stop plates 150 and the stop ring 160 located on both sides of the first elastic component 130.
[0041] In a preferred embodiment, the stop plate 150 and the stop ring 160 extend radially outward, such that their outer edges extend beyond the inner edge of the first elastic component 130 but do not reach the location of the first elastic support layer 134. This prevents friction and collision between the first elastic support layer 134 and the stop ring when the first elastic support layer 134 bulges outward under load, thereby increasing the fatigue life of the first elastic component 130.
[0042] The arrangement of the stop plate 150, the stop ring 16, the fixing screw 125 and the mounting groove can effectively prevent the first elastic component 130 from moving or sliding along the axial direction of the movable core shaft 110 during operation, thereby effectively avoiding the first elastic component 130 from bearing an offset load for a long time, and thereby improving the service life of the support device 100.
[0043] In addition, a central through hole 152 is formed in the middle of the stop plate 150 to help reduce the weight of the supporting device 100 .
[0044] like Figure 1 、 Figure 2 and Figure 6 As shown, the second elastic component 140 may include at least one first curved support plate 141. The second curved support plate 141 has a generally semicircular profile. In the case of multiple second curved support plates 141, the multiple (e.g., three or more) second curved support plates 141 are arranged concentrically or eccentrically spaced apart from each other. The remaining area of the second elastic component 140 is filled with a second elastic support layer 144, for example, made of rubber. In other words, the second elastic support layer 144 is provided between adjacent second curved support plates 141.
[0045] The structure of the second elastic component 140 is adaptable to the situation where the existing gear box 200 is configured with a circular connection hole 210. In other words, the support device 100 of the present invention can be used for assembly, support and vibration reduction without modifying the gear box 200.
[0046] However, if desired, the structure of the gearbox 200 may be modified so that the connecting hole 210 has a rectangular cross-section. In this case, the second elastic component 140 may also be provided with a second planar support plate similar to the first planar support plate and a second auxiliary support plate similar to the first auxiliary support plate.
[0047] like Figure 2 As shown, a stop ring 160 can also be provided on both sides of the second elastic component 140. The stop ring 160 is sleeved on the movable core shaft 110. A stop ring threaded hole 161 is constructed on the stop ring 160 (see Figure 7 ), a core shaft threaded hole 111 is constructed at the corresponding position of the movable core shaft 110 (see Figure 8 ). Thus, the stop ring 160 can be fixedly connected to the movable mandrel 110 via screws. The stop ring 160 extends radially outward, so that its outer edge extends beyond the inner edge of the second elastic component 140 (i.e., the inner edge of the second curved metal plate 141 located at the longitudinal innermost side). Thus, the stop rings 160 located on both sides of the second elastic component 140 can fix the axial position of the second elastic component 140 relative to the movable mandrel 110.
[0048] In a preferred embodiment, the stop ring 160 extends radially outward, such that its outer edge extends beyond the inner edge of the second elastic component 140 but does not reach the location of the second elastic support layer 144. This prevents friction and collision between the stop ring and the second elastic support layer 144 when the second elastic support layer 144 bulges outward under load, thereby increasing the fatigue life of the second elastic component 140.
[0049] from Figure 1and Figure 2 It can be seen that after the support device 100 is assembled, the movable mandrel 110 is elastically supported simultaneously by the one second elastic component 140 and the two first elastic components 130. The arrangement of the one second elastic component 140 and the two first elastic components 130 effectively increases the force-bearing area of the elastic structure and reduces the average stress, thereby facilitating an increase in the fatigue life of the support device 100. Furthermore, in this case, the effective positioning of the first and second elastic components 130, 140 prevents the generation of additional bending moments on the movable mandrel 110, thereby effectively extending the service life of the support device 100.
[0050] As needed, the supporting capacity and vibration reduction capacity of the supporting device 100 can be adjusted by adjusting the pre-compression amounts of the first elastic component 130 and the second elastic component 140 .
[0051] The support and vibration reduction capabilities of the support device 100 can be adjusted as needed by adjusting the shape, size, thickness, and layout of each support plate (including the first curved support plate 131, the first flat support plate 132, the first auxiliary support plate 133, and the second curved support plate 141). The support plates can be made of metal.
[0052] As needed, the supporting capacity and vibration reduction capacity of the support device 100 can be adjusted by adjusting the material of the elastic supporting layer (including the first elastic supporting layer 134 and the second elastic supporting layer 144). For example, the elastic supporting layer can be made of natural rubber, polyurethane rubber or other appropriate polymer materials.
[0053] The supporting device 100 and the wind turbine gearbox assembly including the same can effectively increase the service life of the wind turbine by at least 50%.
[0054] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
