• Classification
  • Rigid Couplings: They have no compensation performance. They are simple in structure, easy to process, and low in cost. They are suitable for medium and low-speed applications with stable loads. Examples include sleeve couplings, split-muff couplings, and flange couplings.
  • Flexible Couplings: They are divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former can only compensate for the relative displacement of the two shafts. Commonly used ones include slider couplings, gear couplings, and universal couplings. The latter can not only compensate for displacement but also damp vibrations. Commonly used ones include elastic sleeve pin couplings, elastic pin couplings, and tire couplings.
  • Unconventional Couplings: Such as magnetic couplings and fluid viscous couplings. Magnetic couplings have a simple structure, a wide application range, and easy torque adjustment, but they have high requirements for bearings and will run unsteadily when reversing temporarily. Fluid viscous couplings have smooth transmission without impact, can isolate torsional vibrations, and have automatic overload protection, but they are not suitable for transmissions with a fixed transmission ratio.

• Definition and Function
  • Connection and Transmission: A coupling is a mechanical device used to connect the ends of two shafts or a shaft and a rotating part together to transmit torque. It can transfer motion and torque from one end to the other, ensuring that the connected components rotate synchronously. It is a key component in the mechanical transmission system.
  • Compensation for Displacement: It can, to a certain extent, make up for the offset between the two shafts, including radial displacement, angular displacement, and axial displacement. It reduces the additional stress caused by the misalignment of the shafts and protects the shafts and connected equipment.
  • Buffering and Vibration Damping: Some couplings have the ability to buffer and damp vibrations. They can reduce the vibrations of the mechanical transmission system and lower the peak impact load. For example, they play an important role in machines that start and stop frequently or contain unbalanced components.
  • Overload Protection: Some couplings also have an overload safety protection function. When the torque exceeds a certain limit, they will slip or disconnect to prevent damage to the system caused by excessive loads.
