Oldham Coupling
Oldham Coupling
An Oldham coupling is a mechanical component used to connect two shafts while compensating for misalignment. It consists of two hubs and a central disc, allowing for angular, radial, and axial misalignment. Oldham couplings are known for their ability to transmit torque efficiently with minimal backlash, making them ideal for applications requiring precise motion, such as robotics, CNC machines, and automated systems. They are durable, easy to install, and provide a compact solution for maintaining performance in systems with imperfect shaft alignment.
An Oldham coupling is a type of mechanical coupling used to transmit torque while compensating for misalignments between shafts. It is primarily used in applications where precise alignment is critical and angular, radial, or axial misalignments need to be accommodated. Here’s a detailed product description:
Oldham Coupling Overview:-
The Oldham coupling consists of three main components:
Two hubs: These are attached to the shafts on either side of the coupling. The hubs are typically made from materials such as aluminum, steel, or stainless steel, depending on the application and required strength.
Central disc (or Oldham disc): This component fits between the two hubs and serves to transmit torque while allowing for misalignment. The disc typically features grooves or slots that allow it to slide within the hubs, permitting axial, radial, or angular displacement between the two shafts.
Key Features:
Torque transmission: The coupling effectively transmits torque while maintaining smooth and reliable operation, even when the shafts are not in perfect alignment.
Low backlash: Due to the design of the Oldham coupling, it provides minimal backlash, which is crucial in precision applications such as robotics or CNC machinery.
Ease of installation: These couplings are easy to install and replace, making them ideal for both new designs and retrofit applications.
In summary, the Oldham coupling is a reliable and effective solution for connecting misaligned shafts, offering efficiency, durability, and ease of use across various applications in industries such as robotics, CNC, and medical equipment.
