Quattro PHQ-ME planetary gearboxes

Features of Quattro PHQ-ME planetary gears:

  • Innovative 4-planetary system!
  • Higher torques than standard planetary gears.
  • Wide range of available gear ratios up to 600:1.
  • Increased torsional and radial stiffness.
  • Output shaft: rotating 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 gears, max 59 – 64 dB.
  • Low moments of inertia.
  • Rigid output bearing due to preload.
  • Continuous operation without additional cooling.
  • Ambient temperature from 0° C to 40° C (other temperature range on request).
  • Max. gear housing temperature ≤ 90 °C.
  • Protection class IP65.
  • Any operating position.
  • Synthetic gear oil type CLP HC ISO VG 150.
  • One coat of primer in RAL7001 or RA9005.
  • Radial shaft sealing rings FKM input / NBR output.
  • For duty cycles > 60% and higher ambient temperatures, we recommend radial shaft sealing rings made of FKM at the output.

Optional versions of Quattro PHQ-ME planetary gear units:

  • Reinforced axial and radial bearing of the output shaft for sizes PHQ4-PHQ5.
  • 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 primers and in any RAL colour.
  • Washdown anti-corrosion design.
  • Protection class IP66.
  • Without adapter and clutch – directly with EZ/LM servo motors.
  • With safety brake in the gear adapter.
  • Change of oil quantity in bidirectional operation in the movement range from ±20° to ±90°.
  • Cyclic reverse operation ≤ ± 20° on REQUEST.

Features of the Quattro PHQ planetary gear 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 the 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):

  • Strong, laser-welded bellows clutch with expansion
  • With integrated thermal length compensation, compensates linear expansion of the motor shaft
  • Motor shaft separated from axial forces

ServoStop servo motor adapter with safety brake (MB)

Examples of applications for PHQ-ME planetary gear units:

  • Industrial rotary tables.
  • Robotics.
  • Bending machines.
  • Industrial and welding turntables.
  • Linear rack and pinion drives.
  • Drives for machine tools and milling machines.
  • Industrial machines and devices.
