High Precision Oldham Shaft Coupling for Automation Machinery
The High Precision Oldham Shaft Coupling is a 3 piece design that provides excellent torque transmission while protecting machinery components. The 2 aluminum hubs are press fit with a center disk, which features slots that mate with the drive tenons on the hubs. The center disk slides on the tenons of each hub to transmit torque, accommodating a small amount of angular and axial misalignment. These couplings are especially useful in applications with parallel misalignment.
Our company offers Oldham couplings in set screw or clamp styles with bores ranging from 4mm to 35mm. The interchangeable inch and metric hubs (set screw, clamp style, keyed, or keyless) can be combined into a single coupling as long as they have the same outside diameter. Oldham coupling hubs are standard in black anodized aluminum for improved lubricity, increased life, and low inertia. Hubs are also available in stainless steel upon request for increased corrosion resistance.
Features
- High absorption capacity of radial misalignment
- No kinematic errors in transmission
- Elimination of loads on shaft
- Mechanical protection against excessive torque
- Replaceable disc
Application
The High Precision Oldham Shaft Coupling is ideal for many light duty industrial and motion control applications and can protect more expensive machinery components. For example, the oldham coupling acts as a torque limiter during overload. When the disk fails, it breaks cleanly and does not allow any transmission of power. Oldham couplings also have the advantage of electrical isolation due to the non-conductive nature of the center disk, preventing electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.
