Oldham couplings
The KSK Oldham coupling, also known as a cross-slide coupling, as well as the CPG Oldham coupling is particularly popular due to its ease of installation.
What is an Oldham coupling?
An Oldham coupling is a mechanical component used in certain applications to create a positively locking connection between two rotating shafts. It consists of two aluminum hubs and a plastic spacer that connect the two hubs together. We offer the aluminum shaft hubs in three different versions.
How do Oldham couplings work?
The central disc piece has two grooves that are perpendicular to each other, and the outer hubs each have a recess that fits into the grooves. During rotation, the plastic element can move axially to compensate for shaft misalignment.
What is the main function of an Oldham coupling?
Oldham couplings are widely used in machinery and equipment to ensure smooth and precise power transmission, especially when the two shafts are not perfectly aligned.
The advantage of an Oldham coupling is that it allows axial displacement between shafts while transmitting torque. It can help compensate for misalignment between the shafts and reduce vibration. It can also help minimize shock loads and overloads because it provides some damping.
Where are Oldham couplings installed?
A cross-slide coupling is often used in servo motor, metering and low-torque applications. The transmission of torque is usually secondary with an Oldham coupling, but it is all the more important to achieve precise positioning. This is especially true for servo motors, where the Oldham coupling is used between the motor shaft and the encoder.
Who developed the Oldham coupling?
It was developed in Ireland in 1820 by John Oldham and named after him.
What distinguishes Miki Pulley's Oldham couplings?
Our Oldham couplings are unbeatably priced compared to our competitors and have extremely fast delivery times for a wide range of bore combinations ex works.
