Beam Coupling verses Twin Spring Coupling
Twin Spring coupling can
- Speeds: Up to 5000 rpm
- Peak Torque Largest Size ft lbs (Nm) 300 ft lbs (407) 500ft lbs (678)
- Standard Coupling sizes 1-1/3/8” (25.4-35mm)
- Temperature: -20° to +290°F , (-4° to +140°C)
- Connection: Spline
- Torsionally rigid design at angles less than 10°
- Minimal backlash
- No moving parts
The servo coupling has been an industry standard for a number of years, for engineers looking for a flexible coupling solution for high speed minimal misalignment applications. The downside is it wasn’t able to handle angles much larger than 2° and the ability to handle torque is minimal.
The Twin Spring coupling dual spring design allows for minimal windup, non-balanced maintenance free coupling solution with the positives of increased torque capacity and increased flexibility even at speed.
This means where applications that need increased torque and misalignment while still working at high speed can now be achieved without resorting to a jaw or elastomeric coupling (which still cannot work at increased angle misalignment.
The Twin Spring coupling contains no internal components that require maintenance so we offer the positives of increased torque and misalignment in one coupling without the worry of maintenance.
At low angle misalignment, Twin Spring coupling maintains its torsional rigidity and continues to do so as misalignment continues to increase due to the pivoting central ball bearing which allows torque to transfer through the coupling
