PH-ME planetary gearboxes
Features of PH-ME planetary gear units:
- High-performance servo gear units with increased torsional and radial stiffness.
- Output shaft: rotary flange shaft.
- Precise – standard or reduced rotational clearance.
- No positioning errors – gear ratio in the form of a fraction.
- Maintenance-free – no oil change or maintenance required.
- Quiet – helical gear wheels, max 59 – 64 dB.
- Radial sealing rings for FKM input shaft / NBR output shaft.
- Low moments of inertia.
- Stiff output bearing due to preload.
- Continuous operation without additional cooling.
- Ambient temperature from 0° C to 40° C (other temperature range on request).
- Maximum temperature of the gear housing ≤ 90 °C.
- Protection class IP65.
- Any working position.
- Synthetic gear oil type CLP HC ISO VG 150.One coat of primer in color RAL7001 or RA9005.
Optional versions of the PH-ME planetary gear units:
- Reinforced axial and radial bearing of the output shaft for sizes PH3-PH5.
- Double sealing of the servo motor adapter.
- FKM VITON seal for high temperatures.
- With modular helical gear wheel.
- Explosion-proof design according to ATEX Directive 2014/34/EU.
- Special oils for the food industry on request.
- Two or more paints and in any RAL colour.
- Washdown anti-corrosion design.
- Protection class IP66.
- Oil quantity change in bidirectional operation in the movement range from ±20° to ±90°.
- Reversing cyclic operation ≤ ± 20° on request.
- Without adapter – directly with EZ/LM servo motors.
- With safety brake in the gear unit adapter.
Features of Stober gear motor adapters
- Quick and easy attachment of any servo motor
- One-piece, robust clamping clutch with expansion function
- Low mass moments of inertia for highest operating dynamics
- Balanced for quiet, vibration-free operation, even at high speeds
- Wide selection of motor shaft diameters and lengths
- Flawless fit thanks to precise motor centring
- The motor can be removed in any position
- Double adapter seal for large gear models
- Optionally without adapter and clutch – direct mounting of EZ or LM servo motor
- To reduce play, the motor shaft bearing must be of an axially play-free design
EasyAdapt clutch (ME/MEL)
- One-piece, robust clamping clutch with expansion function
FlexiAdapt clutch (MF):
- Robust, laser-welded bellows clutch with expansion function
- With integrated thermal length compensation, compensates for linear expansion of the motor shaft
- Motor shaft separated from axial forces
ServoStop motor adapter with safety brake (MB)
