      standard gear box series PE
        Gear box series PE includes 1-stage to 3-stages planetary gear boxes, with ratios from 1:1 until 512:1.
These gear boxes our mounted directly to the motor.
A pitch, which makes part of the first planetary stage of the gear box, is mounted via drilling and a key to the motor shaft.
The gear head is mounted on top of the pitch.
The technical advantages of that system are
  • smaller gear box length
  • much smaller inertia of the pitch compared to a standard gear box coupling
    – results in better dynmical performance (higher acceleration possible)
  • 100% safe against slipping between motor shaft and gear box
