[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Example 1

[0016] like Figure 1 As shown, a specific embodiment of a split fluid coupling described in the present invention includes: an impeller 2 and a body 1. The impeller 2 and the body 1 are independently cast components and are connected by riveting. Two riveting points are provided on the impeller 2, namely a first riveting point 5 near the middle bottom and a second riveting point 6 near the outer ring. The two riveting points are spaced between the blades 3 to ensure a firm connection between the impeller 2 and the body 1. Blades 3 are equidistantly arranged inside the impeller 2, and a cover plate 7 is installed at one end of the blade 3 near the center. Connecting columns 8 are equidistantly provided at the bottom of the cover plate 7 in the circumferential direction. The connecting columns 8 are fixedly connected to the impeller 2 for fixing the cover plate 7 and thereby reinforcing the blades 3. The connection between the cover plate 7 and the blades 3, the connecting columns 8 and the cover plate 7, and the connecting columns 8 and the impeller 2 are all welded to ensure the firmness and sealing of the connection.

[0017] In order to improve the running stability of the coupler and reduce vibration, a damping boss 4 is integrally formed on each blade 3. The damping boss 4 can effectively absorb and disperse the impact caused by fluid power, thereby extending the service life of the coupler.

[0018] The working principle of the utility model is as follows: the impeller 2 and the body 1 are cast independently to ensure the structural integrity and precision of each; the blades 3 and the cover plate 7, the connecting column 8 and the cover plate 7, and the connecting column 8 and the impeller 2 are fixed by welding to ensure the firmness and sealing of the connection; after the impeller 2 and the body 1 are precisely positioned, they are riveted at the first rivet welding point 5 and the second rivet welding point 6 to complete the final assembly.

[0019] Power is transmitted through the working medium between the two relatively rotating impellers 2. The medium circulates between the impellers 2, generating a hydraulic coupling effect, thereby realizing the transmission of power from the active end to the driven end. A riveted welding connection method is adopted, and through the designed first riveted welding point 5 and second riveted welding point 6, a firm connection between the impeller 2 and the body 1 is achieved, while ensuring the strength and rigidity of the connection and extending the service life of the hydraulic coupling. The split structural design makes the hydraulic coupling more convenient and quick when maintaining and replacing parts. At the same time, its structure also has strong adaptability and can be widely used in various mechanical equipment requiring hydraulic transmission. The blades 3 are fixed by a cover plate 7 and connecting columns 8 arranged equidistantly around the circumference. This structure enhances the stability of the blades 3. The damping boss 4 can enhance the rigidity of the blades 3 and prevent flutter.

[0020] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0021] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention. Modifications or deformations that do not involve creative work are still within the scope of protection of the present invention.
