Servo Planetary Gearboxes/Gearmotors PPG

Precision planetary gear PPG

  • 3 sizes
  • 2 output variants (output flange, output shaft)
  • Gear ratios 4 to 10 (single-stage)
  • Max drive speed (min-1) up to 6,000
  • Rated torque up to 330 Nm
  • Acceleration torque up to 550 Nm
  • Circumferential backlash < 6 arc min (optional < 3, < 1)

The PPG precision planetary gear is characterized by three major design advantages: 


PPG load compensation ensures minimized friction for smooth running and for outstandingly high synchronizing, and last but not least, a long service life.


The PPG compensating coupling has a unique, space-saving angle error compensation feature.  The low mass moment of inertia ensures high motive response.  The coupling operates without backlash, with high rigidity and has length compensation. 


The friction optimized PPG seals ensure a lower starting inertie. 
The thermal load limit is very high due to low friction losses.
