What coupling is used to connect two shafts?

To connect two shafts, various types of couplings can be used, depending on the application requirements. Some common types include:

  • Rigid Couplings: Used when precise shaft alignment is required and no relative movement between the shafts is allowed.
  • Flexible Couplings: Accommodate minor misalignments and provide vibration damping.
  • Fluid Couplings: Transmit power through a fluid medium, offering smooth torque transmission and inherent overload protection.

What are the two general types of shaft couplings?

Generally, shaft couplings can be categorized into two types:

  • Rigid Shaft Couplings: These are used where shafts are precisely aligned and no misalignment is expected. They provide a solid connection with high torque transmission but can be unforgiving to slight alignment errors.
  • Flexible Shaft Couplings: These allow for some degree of misalignment between connected shafts and can absorb vibration and shock. They are ideal for applications where alignment may not be perfect or where dynamic loads are present.
