Applications
Robotic arms / automation
Helical planetary gearboxes for low backlash + DSP Rotary Table lines whose hollow centre carries wiring and piping.
Where the parts sit
- ① Planetary gearbox at the axis drive — Reduces motor speed and multiplies torque for the axis; ratio and backlash are checked on the selection page.
- ② Gear rack along the long-travel bed — Converts pinion rotation into long linear travel; module, length and straight vs. helical must be stated in the inquiry.
- ③ Rotary table at the indexing station — Positions and holds the workpiece directly on the table; hollow centre carries wiring and piping. IP40 — do not assume suitability for a wet or food line.
Product lines used
Helical planetary gearboxes for low backlash + DSP Rotary Table lines whose hollow centre carries wiring and piping.
Key parameters
- Helical backlash B1 typically ≤3–5 arcmin, B2 ≤7–12 arcmin (varies by frame).
- Rotary repeatability ≤15 arcsec (DSP280 / DSP450: 20 arcsec); hollow centre for cabling.
- Planetary ratios 3–100; motors 42 / 57 / 86 / 110 stepping or 50 / 100 W to 3 kW AC servo for rotary lines.
Environment limits
- Inertia, duty cycle and flange / shaft match decide robot-axis fits — none of them is settled by the ratio calculator alone.
- Clean-room or dust requirements are not claimed; state the environment in the inquiry.
What to state in the inquiry
- Inertia, duty cycle, flange and shaft, cable / piping through the hollow centre.
