What is an Oldham Coupling? Advantages and Applications Explained
🔧 Introduction
An oldham coupling is a flexible shaft coupling designed to compensate for misalignment while transmitting torque with zero backlash. It is widely used in precision systems such as encoders and servo motors.
⚙️ How Oldham Coupling Works
The oldham coupling consists of three parts: two hubs and a center disc. The disc slides between the hubs to accommodate misalignment.
⭐ Key Benefits
- Zero backlash
- High precision
- Good misalignment compensation
- Low noise operation
🏭 Applications
- Encoder systems
- CNC machines
- Automation equipment
