Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a claw-type coupling structure. Background Art

[0002] In industrial machinery transmission systems, couplings are a common connection device used to connect two rotating shafts, transmitting torque and motion. While traditional rigid couplings can efficiently transmit torque, they perform poorly with misalignment, vibration, and shock, which can easily lead to equipment wear and failure. Therefore, a coupling structure that can both efficiently transmit torque and effectively absorb vibration and shock is needed.

[0003] A Chinese patent discloses a radially buffered cross coupling (publication number: CN 216642841U) including a connecting slider, a first protrusion fixed to one side of the connecting slider, a first connecting block provided on the outside of the first protrusion, a sliding groove provided on one side wall of the first connecting block, the first connecting block and the connecting slider are matched and connected through the sliding groove and the first protrusion, a second protrusion fixed to the other side of the connecting slider, a second connecting block slidingly provided on the outside of the second protrusion, and a coupling block fixed to the surface of one side of the first connecting block. However, this coupling performs poorly when facing problems such as misalignment, vibration and impact, which can easily lead to equipment wear and failure, and poor torque transmission effect. Therefore, a claw coupling structure is needed. Utility Model Content

[0009] Preferably, the auxiliary positioning component includes small shock dampers. The number of the small shock dampers is 3 and they are arranged correspondingly. The small shock dampers can further absorb vibrations and improve the stability of the system; by reducing vibrations, the wear of components can be reduced, thereby extending the service life of the entire system.

[0010] Preferably, dust-proof sealing rings are provided in the gaps between the elastic connecting member and the driving half coupling and the driven half coupling. The dust-proof sealing rings can effectively prevent dust and other impurities from entering the inside of the coupling, protect the internal parts from contamination; keeping the inside of the coupling clean helps to reduce wear, improve the reliability and life of the system.
