In Line – ServoFit Precision Planetary
“PH” Series
The “PH” Series ServoFit™ Precision Planetary Gearheads are designed for exacting demands on torsional and tilting rigidity. Some features are:
- Excellent axial load capacity
- HeliCamber® gear technology provides minimum wear, low backlash, and low noise
- Gears are case hardened to 61 Rockwell “C” and ground for maximum efficiency
- Ring gear machined integral to the housing – not welded or pressed in – provides greater concentricty and more precise alignment
- The output flange dimensions are ISO 9409 and allow easy mounting to rotary or indexing tables, pinions, timing belt pulleys, transmission shafting, etc., without using a coupling
- FKM seals, for the smallest possible diameter, reduces friction and heat buildup, increases efficiency, and allows continuous duty operation without addition cooling
- Oversized tapered roller bearings and shafts for high radial load capacity and superior torsional stiffness
- Single piece steel housing provides greater concentricity and more precise alignment
- 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.
- Also available as ServoCool (sizes PH4 thru PH10) or with input shaft
PHA Series
The “PHA” Series is well suited where a smooth, precise, reliable drive is needed. Some features are:
- 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 clamp 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.
- 90-96% Efficiency
- Ground and honed gearing
- Also available as ServoCool (sizes PHA4 thru PHA10)
