Description

Technical Field

[0001] This utility model relates to the technical field of couplings for generators, and specifically to a coupling for generators. Background Technology

[0002] A coupling is a connecting tool that connects two shafts or a shaft to a rotating component. It is mainly responsible for connecting two rotating shafts to the shaft that needs to rotate. It is widely used in the mechanical field and can sometimes be used as a protective component to provide overload protection.

[0003] In generators, couplings are typically used to connect rotating components. However, when installing the coupling on the generator output shaft, ensuring the shafts are aligned after mating requires manual rotation to check alignment, which is cumbersome. Therefore, this paper provides a generator coupling that solves these problems. Utility Model Content

[0004] To solve the problems mentioned above, the technical solution adopted by this utility model is: a coupling for a generator, comprising: a first coupling end seat and a second coupling end seat, both the first coupling end seat and the second coupling end seat having bolt fixing holes, a movable rod being slidably connected to one end of the second coupling end seat, a pressure sensor being connected to one end of the movable rod inside the second coupling end seat, and a limit ring being provided on the outer side of the movable rod near the pressure sensor.

[0005] As a preferred technical solution of this utility model, one end of the movable rod is located outside the second coupling end seat and connected to one side of the fixed ring. The number of movable rods is set to three, and the three movable rods are divided into three equal parts on one side of the fixed ring.

[0006] As a preferred embodiment of this utility model, a data connection port is provided on the outer side of the fixed ring, and the detection end of the pressure sensor is directly opposite the first coupling end seat.

[0007] As a preferred embodiment of the present invention, the first coupling end seat is sleeved on the outer circumference of the drive shaft, and the second coupling end seat is sleeved on the outer circumference of the driven shaft. Both the drive shaft and the driven shaft are provided with wedges on their outer ends.

[0008] As a preferred embodiment of this utility model, the movable rod is fitted with a spring between the second coupling end seat and the fixed ring, and the number of springs is three.

[0009] As a preferred embodiment of this utility model, the inner rings of the first coupling end seat and the second coupling end seat are provided with grooves, which match the wedges. The corresponding grooves of the first coupling end seat and the second coupling end seat are provided with screw slots. The first coupling end seat and the second coupling end seat are connected to each other by bolts passing through bolt fixing holes.

[0010] The present invention has the following advantages: After the first coupling end seat and the second coupling end seat are connected by bolts passing through the bolt fixing holes, pushing the fixing ring can make the pressure data detected by the three pressure sensor detection ends contact the end face of the first coupling end seat to check whether they are consistent, thereby making it easy to adjust the drive shaft and the driven shaft to be on a straight line.

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figures 1-4 This utility model discloses a coupling for a generator, comprising: a first coupling end seat 1 and a second coupling end seat 2. Both the first coupling end seat 1 and the second coupling end seat 2 are provided with bolt fixing holes 3. A movable rod 4 is slidably connected to one end of the second coupling end seat 2. A pressure sensor 5 is connected to one end of the movable rod 4 inside the second coupling end seat 2. A limit ring 6 is provided on the outer side of the end of the movable rod 4 near the pressure sensor 5.

[0020] Combination Figure 2 and Figure 3 As shown, the movable rod 4 is located outside the second coupling end seat 2, with one end connected to one side of the fixed ring 8. There are three movable rods 4, which are divided into three equal parts on one side of the fixed ring 8. A data connection port 9 is provided on the outer circumference of the fixed ring 8. The detection end of the pressure sensor 5 is directly opposite the first coupling end seat 1. The pressure sensor 5 can be operated by connecting the data cable to the data connection port 9, and the consistency of the pressure data can be detected by the three pressure sensors 5.

[0021] Combination Figure 2 and Figure 4 As shown, the first coupling end seat 1 is sleeved on the outer circumference of the drive shaft 10, and the second coupling end seat 2 is sleeved on the outer circumference of the driven shaft 11. Both the drive shaft 10 and the driven shaft 11 have wedges 12 on their outer ends. The wedges 12 ensure that the first coupling end seat 1 does not rotate with the drive shaft 10 and the second coupling end seat 2 does not rotate with the driven shaft 11. The movable rod 4 is sleeved between the second coupling end seat 2 and the fixed ring 8, and three springs 7 are provided. The inner rings of the first coupling end seat 1 and the second coupling end seat 2 have grooves 13 that fit with the wedges 12. The first coupling end seat 1 and the second coupling end seat 2 have screw slots 14 at the corresponding grooves 13. The first coupling end seat 1 and the second coupling end seat 2 are connected by bolts passing through bolt fixing holes 3.

[0022] Specifically, in use, the first coupling end seat 1 is first fitted onto the end of the drive shaft 10, and the second coupling end seat 2 is fitted onto the end of the driven shaft 11. Then, the first coupling end seat 1 is fixed onto the drive shaft 10 and the second coupling end seat 2 is fixed onto the driven shaft 11 by screws threaded into the screw groove 14. Next, the first coupling end seat 1 and the second coupling end seat 2 are connected by bolts passing through the bolt fixing hole 3. Then, by pushing the fixing ring 8 to move the movable rod 4, the movable rod 4 moves the pressure sensor 5, so that the detection ends of the three pressure sensors 5 contact the end face of the first coupling end seat 1. By observing the data detected by the three pressure sensors 5, it can be determined whether the drive shaft 10 and the driven shaft 11 are aligned in a straight line.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
