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.
