Harmonic Drive HPN-A Inline Planetary Gearboxes
Harmonic Drive HPN-A Inline Planetary Gearboxes
Harmonic Drive HPN-A is an inline servo-mount planetary gearbox family using helical gearing. It is distinct from the HPN-L face-mount and HPN right-angle arrangements, and its specified backlash is finite rather than the zero-backlash claim associated with some strain-wave products.
Review Summary
HPN-A merits comparison for a servo axis needing compact reduction and a documented low-backlash planetary transmission. Select frame, ratio, coupling and load basis together. Compare the repeated and momentary torque limits separately, and do not turn a gear backlash value into the positioning accuracy of the complete machine.
Construction Inline planetary gearbox with helical gearing Frame selection Five family sizes: 11, 14, 20, 32 and 40 Reduction range Family ratios 3:1–50:1; availability depends on size Backlash Less than 5 arc-min single-stage; less than 7 arc-min two-stage Output choices Shaft configurations include keyed/center-tapped and smooth-shaft arrangements Example HPN-11A-5 Published rated torque columns: 9 Nm L10 and 14 Nm L50; preserve the selected rating basis Example transient limits HPN-11A-5: 16 Nm repeated-peak limit and 40 Nm momentary-peak limit Example input speed HPN-11A-5 maximum input speed 10,000 rpm; not the maximum for every family member Applications and Industries
