ANGULAR RACK AND PINION DRIVES ZV-KS-ME

Angular Servo Gearboxes with Plug-In Pinion

Modular ZV Gears:

  • Gear quality class 6 according to DIN 3962.
  • Helical gearing, surface-hardened and ground (left-hand 19° 31′ 42″).
  • Backlash-free shaft-hub connection, shrink-fitted and keyway-secured.
  • The corresponding rack must have a right-hand design (19° 31′ 42″), minimum quality class 8, material C45, induction-hardened.
  • Two pinion mounting positions available:
    • (E) Pinion at the end of the output shaft.
    • (S) Pinion close to the gearbox, ensuring higher permissible feed forces.
  • Pinion and rack ZV: Lubrication is the customer’s responsibility; high-quality synthetic oil-based greases (NLGI class 0) are recommended.

Modular ZS Racks:

  • Precision helical gearing, quality class 6.
  • Spiral teeth, hardened and ground.
  • Module sizes ranging from 2 to 6.
  • Double number of mounting holes every 62.5 mm.
  • Maximum feed force from 12.6 to 83.1 kN.
  • Two length groups: 500 mm and 1000 mm.

 

Properties of KS Planetary-Bevel Gearboxes:

  • Precision – standard and reduced backlash.
  • Fractional gear ratio – eliminates positioning errors.
  • Quiet operation – helical gearing.
  • Maintenance-free – no oil changes required.
  • Pre-lubricated for the entire service life.
  • Mounting position – to be specified upon ordering.
  • Ambient temperature: 0°C to 40°C (other temperature ranges available on request).
  • Filled with synthetic lubricant CLP HC ISO VG 150.
  • Maximum allowable gearbox surface temperature ≤ 90°C.
  • Protection class: IP65 (optional IP66).
  • Bearing options: standard, reinforced axial or radial bearings.
  • Output shaft sealing: standard NBR, optional FKM.
  • For duty cycles > 60% and higher ambient temperatures, radial shaft sealing rings made of FKM are recommended at the output.
  • Gearbox housing made of cast iron.
  • Standard paint color: black RAL9005 (other colors available on request).

Optional KS Planetary-Bevel Gearbox Configurations:

  • Mineral oil for applications in the food, beverage, and pharmaceutical industries.
  • Oil expansion tank for vertical mounting position (EL5).
  • Direct mounting of STOBER servo motors from the EZ/LM series without adapter or coupling.

Properties of Angular Adapters for KS Planetary-Bevel Gearboxes:

  • Quick and easy mounting for any servo motor.
  • One-piece, durable clamping coupling with expansion function.
  • Lowest mass inertia moments for maximum dynamic performance.
  • Balanced design for quiet, vibration-free operation, even at high speeds.
  • Wide selection of motor shaft diameters and lengths.
  • Precise alignment ensures perfect motor fit.
  • Motor can be disassembled in any position.
  • Optional double sealing for larger gearbox models.
  • Optional direct mounting of EZ or LM servo motors without adapter and coupling.
  • To reduce backlash, the motor shaft bearing must be designed without axial play.

EasyAdapt (ME/MEL):

  • One-piece, durable clamping coupling with expansion function.

FlexiAdapt (MF):

  • Durable, laser-welded bellows coupling with expansion function.
  • Integrated thermal length compensation, accommodating the linear expansion of the motor shaft.
  • Motor shaft isolated from axial forces.
