RP⁺

Name: RP+
Brand: WITTENSTEIN group

Planetary gearbox

The RP⁺ was specially developed for rack and pinion systems and offers maximum rigidity and easy installation. The integrated slotted holes in the output flange allow the pinion to be easily adjusted. Power density, rigidity and ease of assembly set new standards.

4 – 220

Ratio

352 – 10450 Nm

Max. torque

≤ 1 – 3 arcmin

Backlash

Machine connection

Integrated slotted holes allow easy adjustment of the pinion to the rack, for example, and increase system rigidity by eliminating the need for adjustment plates

Absorption of maximum forces

Reinforced bearing to absorb maximum forces – with a compact design

Positioning accuracy

Low backlash and highest possible torsional rigidity ensure maximum positioning accuracy at the tool center point

The R-flange sets the standard

Premium Linear System with RP⁺

System output for even greater flexibility

Rigidity for high-precision drive solutions

cynapse^® & smart services

The R-flange is standard for the RP⁺. The slotted holes integrated into the gearbox flange allow easy adjustment of the gear with the pinion mounted on the rack.

The RP⁺ for perfectly matched rack and pinion systems for high to very high demands. Typical areas of application are laser machines, wood, plastic, and composite material processing centers, cutting machine tools, e.g., HSC milling machines, as well as highly dynamic and precise handling applications.

The system output can be used to implement a wide variety of gearbox and pinion configurations. The inputs can be optimized for rigidity, feed force, or feed speed, depending on requirements.

The high torsional rigidity of the RP⁺ gearboxes, combined with the tilting rigidity, C_2K,lin, and engagement spring stiffness, Cγ, together with a highly rigid design, have a positive effect on the natural frequency and thus on the control behavior of the machine.

With cynapse^® and smart services, you can unleash the full potential of your drive system: sensor data is processed, visualized, and analyzed intelligently. Find out how the combination of gearboxes with cynapse^® and our Smart Services can make your digital production faster, safer, and more efficient.
