[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present utility model more clear, the technical scheme of the present utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without making creative labor belong to the scope of protection of the present utility model.

[0037] It should be noted that like reference numerals and letters refer to like items in the several views, and once an item is defined in one view, it need not be further defined and explained in the subsequent views. In addition, in the drawings, the thickness of components can be exaggerated or reduced for the sake of effective description of the technical content.

[0038] Some embodiments of the utility model will be described in detail below in conjunction with the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] As shown in the drawings, at least one embodiment provides a generator, comprising: a generator body 4, a connecting cover 42 and a shaft coupling, the input shaft 41 is arranged on the generator body 4, one side of the connecting cover 42 is connected with the generator body 4, the other side is connected with the engine, and the shaft coupling is arranged in the connecting cover 42 and connected with the input shaft 41;Wherein, the engine is not shown in the figure. Figure 1 As shown in the drawings, in some embodiments, the shaft coupling comprises: an inner disc 1 and an outer disc 2;Wherein, the inner disc 1 is sleeved on the input shaft 41, and the outer disc 2 is annularly sleeved on the inner disc 1.

[0040] Figure 2 As shown in the drawings, in some embodiments, the connecting cover 42 is provided with an interface 421 away from the generator body 4, and the interface 421 is used to connect some connecting members into the connecting cover 42 and connect with the outer disc 2 of the shaft coupling, so as to connect the engine and the generator body 4 and realize power transmission.

[0041] As shown in the drawings, in some embodiments, the connecting cover 42 is provided with an interface 421 away from the generator body 4, and the interface 421 is used to connect some connecting members into the connecting cover 42 and connect with the outer disc 2 of the shaft coupling, so as to connect the engine and the generator body 4 and realize power transmission. Figure 1 Figure 2 Specifically, the inner diameter size of the interface 421 is limited by the engine model, that is, the engine needs to be connected with the connecting cover 42, so a circle of threaded holes 422 needs to be arranged on the connecting cover 42, when the model of the engine is fixed, the circle formed by each threaded hole 422 is also fixed, so that the maximum inner diameter of the interface 421 is also fixed.

[0042] In the related art, in order to increase the transmission power, the diameter of the inner disc 1 needs to be set larger, and after the diameter of the inner disc 1 is increased, the inner diameter of the outer disc 2 will also be increased;When the diameter of the inner disc 1 is increased to exceed the inner diameter of the interface 421, the outer disc 2 cannot be directly connected with the engine through the interface 421;Therefore, the inner diameter size of the interface 421 limits the diameter of the inner disc 1, and also limits the transmission power.

[0043] In order to solve the above problems, as shown in the drawings, in some embodiments, the connecting cover 42 is provided with a plurality of threaded holes 422, and the inner diameter of the interface 421 is greater than the diameter of the inner disc 1.

[0044] In order to solve the above problems, as shown in the drawings, in some embodiments, the connecting cover 42 is provided with a plurality of threaded holes 422, and the inner diameter of the interface 421 is greater than the diameter of the inner disc 1. Figure 3 ​​As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0045] As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission. Figure 4 As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0046] In the embodiment, the presence of the vertical part 312 reduces the radius of the horizontal part 311, so that the horizontal part 311 can penetrate the interface 421; wherein the vertical part 312 can but is not limited to be connected with the outer disc 2 by bolts.

[0047] As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission. Figure 3 As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0048] In the embodiment, the transmission disc 32 is connected with the output shaft of the engine, and drives the outer disc 2 to rotate by driving the transmission disc 32 to rotate.

[0049] As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission. Figure 3 As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0050] As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission. Figure 5 As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0051] In the embodiment, the structure of the connecting hole 322 and the input hole 321 can increase the area of the connection and enhance the connection strength; the key groove 121 is arranged to drive the inner disc 1 and the input shaft 41 to rotate synchronously.

[0052] As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission. Figures 6 to 8 As shown in the drawings, in some embodiments, the adapter ring 31 is arranged on the outer disc 2, one side of the adapter ring 31 is connected with the outer disc 2, and the other side penetrates the interface 421, so that the outer disc 2 can be connected with the engine to realize power transmission.

[0053] In this embodiment, the inner plate 1 is connected to the generator body 4, and the outer plate 2 is connected to the engine. The existence of the buffer gap 13 prevents the vibration generated by the engine from being directly transmitted to the generator body 4 during the transmission process, thereby reducing the vibration intensity received by the generator body 4.

[0054] like Figure 9 As shown, in some embodiments, the sidewalls of the arc-shaped external teeth 21 are inclined to form a taper, and the side facing the adapter ring 31 is higher than the side facing the inner disk 1; and the inner wall of the arc-shaped inner groove 11 is inclined and adapted to the arc-shaped external teeth 21.

[0055] Specifically, the inner wall of the arc-shaped inner groove 11 is inclined and adapted to the arc-shaped outer teeth 21, thereby making the width of the buffer gap 13 uniform.

[0056] In this embodiment, since the outer disk 2 and the inner disk 1 are separate, the outer disk 2 needs to be installed on the engine and the inner disk 1 needs to be installed on the generator body 4. Since the two need to be as coaxial as possible, when the inclined arc-shaped external teeth 21 on the side wall are inserted into the inclined arc-shaped inner groove 11 on the inner wall, they will be coaxial after they come into contact. At this time, it is only necessary to connect the output hole 12 to the input shaft 41 and the input hole 321 to the output shaft of the engine to ensure that the input shaft 41 of the generator body 4 is coaxial with the output shaft of the engine. Then, it is only necessary to adjust the inner disk 1 to move a certain distance along the axial direction of the input shaft 41 to form a buffer gap 13.

[0057] like Figures 6 to 8 As shown, at least one embodiment also provides a coupling, including: an inner disk 1, an outer disk 2 and a transition ring 31; the inner disk 1 is connected to the input shaft 41 of the generator body 4; the outer disk 2 is sleeved on the periphery of the inner disk 1; one side of the transition ring 31 is connected to the outer disk 2.

[0058] In some embodiments, the adapter ring 31 has an "L" shaped cross section and includes a horizontal portion 311 and a vertical portion 312; the vertical portion 312 is connected to the outer disk 2.

[0059] In some embodiments, a transmission disc 32 is connected to the horizontal portion 311.

[0060] In summary, this coupling and generator, by setting an adapter ring 31 on the outer disk 2, allows the adapter ring 31 to extend out of the interface 421, thus avoiding the limitation on the diameter of the inner disk 1 caused by the interface 421, which would affect the transmission power.

[0061] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.

[0062] In this document, when an element or layer is referred to as being "on", "engaged to", "connected to", "attached to" or "coupled to" another element or layer, it can be directly on, engaged, connected, attached or coupled to the other element or layer, or intervening elements or layers can be present.
