Harmonic Drive has developed the new HFUS-2A component sets on the basis of the proven HFUC-2A series. The perfomance data for both series are identical. The main difference between the HFUS and HFUC component sets lies in the form of the flexspline. In the case of HFUS the flexspline opens outwards allowing a large hollow shaft to be passed through the gear. HFUS component sets are also used in the HFUS-2UH hollow shaft units, the HFUS-2UJ units with input shaft and the HFUS-2SO/-2SH "Simplicity Units".In addition to the standard version HFUS-2A component sets are also available in a special version with a similar outer diameter of the flexspline diaphragm. We recommend the use of the standard version, can be delivered more quickly.
Advantages:
- Optional hollow shaft with large inner diameter
- High torque capacity
- Excellent positioning accuracy and repeatability
- Compact design
- High single stage ratios
- High torsional stiffness
- Zero backlash
- High efficiency
