Dynapar - Flexible Shaft Coupling
FEATURES
- Maximum mechanical, thermal and electrical protection for shaft connections
- Three-beam helical design restricts torque "wind-up"
- Clamp attachment. No setscrews to score or pit shafts
- Full range of models designed to match specific encoders are supplied with shaft size adapters
ORDERING INFORMATION
Application duty, then by specific encoder shaft size and drive shaft size. Most applications will use the Primary Bore as the encoder end, but it is permissible to reverse the coupling to accommodate specific shaft combinations. Each coupling is supplied with Secondary Bore insulator inserts as listed.
- For extremely high acceleration rates, consider using the next larger coupling size.
- When coupling an encoder to a shaft which is stepped down from a larger size, always use a heavy-duty or extra-heavy duty coupling.
- For maximum life, encoders must be installed and aligned such that the encoder shaft to driving shaft alignment is within the 0.003' TIR NEMA standard, despite the maximum misalignment specified.
