Description

Technical Field

[0001] The invention relates to the technical field of couplings, in particular to a hydraulic serpentine spring coupling with high load-bearing capacity. Background Art

[0002] The serpentine spring coupling is a metal with advanced structure. It transmits torque through serpentine spring sheets. The serpentine spring coupling is the most advanced shaft connection transmission component in the international mechanical field today, and is also a very common shaft connection transmission component.

[0003] For example, a new type of hydraulic serpentine spring coupling with announcement number CN217761777U includes two annular hydraulic sleeves and two protective outer shells. An annular oil storage chamber is arranged inside the two annular hydraulic sleeves. Two oil filling pipes are fixedly connected to the ends of the two annular oil storage chambers. The openings of the two oil filling pipes can be detachably connected with plug bolts. Multiple tooth grooves are arranged on the opposite ends of the two annular hydraulic sleeves. Lubricating oil is filled between the multiple tooth grooves and the protective inner shell. The first sealing gasket implements sealing protection for the internal parts of the protective inner shell. The protective inner When the parts inside the shell are working, they are assisted by the lubricating oil, which not only improves the working efficiency of the internal parts, the serpentine spring and the tooth groove, but also reduces the friction damage between the serpentine spring and the tooth groove, and increases the service life of the overall internal parts. However, when the torque transmitted by the coupling is too large, the serpentine spring is prone to deviate from the joint of the sleeve due to excessive force, thereby affecting the connection effect of the two sleeves, which may cause the connection of the coupling to be unstable, reduce the use effect of the coupling under large load-bearing capacity, and reduce the working efficiency of the coupling.
