Planetary gear PU 45

Gantry cutting machine - planetary gear PU46 with pinion and rack from SPN

On November 10, the handover of the two PU46 planetary gear units took place at the Donauwörth vocational school. The gear units serve as a more detailed illustration for the students to better understand the functional principle of the planetary gear unit. Together, the classmates can disassemble both models and then reassemble them themselves. In this way, the theoretical material learned can be put into practice and consolidated.

The planetary gear units of the PU4 series stand for power density. The use of modern materials in combination with innovative ideas makes for a gear unit of opposites. A powerhouse that impresses with its lightness. Powerful in performance data but still with the best values for mass inertia. Technically at the highest level.

The planetary gear units are used where repeatability and positioning accuracy are important, for example in a portal cutting machine as the drive for the X-axis.


Technical data:  

  • Single-stage
  • Gear ratio 10 : 1
  • Permissible nominal torque 110Nm                                                                                  
  • Low backlash ≤ 4 arcmin                                                                                     
  • efficiency > 97%

Your advantages

  • high acceleration - due to an inertia-optimized motor connection.
  • high torque - due to wide, double-bearing planetary gears
  • high rigidity - due to large shaft dimensions
  • high permissible radial forces - due to tapered roller bearings with optimized bearing spacing
  • low torsional backlash - due to paired drive components
  • low running noise - due to ground helical gearing
  • easy motor mounting - due to tangential clamping with sun gear fixation
  • variable - due to any mounting position
  • maintenance-free - due to lifetime lubrication with synthetic gear oil
  • low energy consumption - due to high efficiency
