(Specifications)

 

PHQ SeriesThe “PHQ” Series ServoFit™ Precision Planetary Gearhead is a four-planet system. This allows the torque to be distributed over 4 planet gears instead of 3, resulting in an increase in output torque of >35% and an increase in torsional rigidity of >80%. Some features are:

  • Advanced gear technology
  • High tensile tempered steel single-piece housing
  • Ring gear machined integral to the housing – not welded or pressed in – provides greater concentricity and more precise alignment
  • Oversized single-piece planet carrier, made of high tensile material, enables use of higher load capacity bearings and provides highest torsional stiffness possible
  • Quiet running
  • FKM seals for the smallest possible diameter — reduces friction and heat build-up, increases efficiency, and allows continuous duty operation without additional cooling.
  • High input speeds
  • Blind pilot hole
  • The motor shaft adaption system allows installation in minutes without special tools. The patented motor coupling is designed to allow thermal expansion of the motor shaft, ensuring long motor life by preventing thrust load on the motor bearings. The triple-split collet, designed for greater concentricity and low inertia, is rated in excess of the gearhead torque capacity. Adapter bushings to fit all motor shafts are provided when necessary. No shaft key is required.

PHQA Series

The “PHQA” Series is the high precision, lowest backlash version.

  • Backlash of 1 arc minute or less
  • Precision selection of parts ensure optimal performance without binding gear teeth, resulting in a more accurate and smooth direct drive
  • Balanced shaft coupling for smooth operation at high speeds
  • The FlexiAdapt™ motor coupling is designed for accurate and precise motor installation. The integrated thermal expansion feature, in the shape of a bellows, compensates for linear thermal expansion of the motor shaft. Adapter bushings are provided when needed to fit any motor shaft.
