Description

Technical Field

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

[0002] Flexible couplings are used to connect the upper half of the drive and driven shafts. They mitigate torsional vibration and impact loads in the drive shafting system, prevent resonance, and compensate for relative misalignment between the two shafts. These couplings utilize highly elastic rubber for transmission, absorbing vibration and shock, and reducing noise, making them widely used.

[0003] Existing flexible couplings are easily damaged by torsional vibration and impact loads of the transmission shaft system during operation, and are prone to aging after long-term use, making them impossible to disassemble. Utility Model Content
