Power and precision in a compact design

The Premium planetary gearbox RP+, perfect for rack and pinion due to reinforced bearings and a special output interface, are now available in a right-angle version RPK+ with hypoid gearing. The axis offset of hypoid gearboxes allows both higher ratios in one section (ratio i = 3 – 10) as well as higher torques compared to bevel gearboxes.The high torque density allows for an extremely compact, space-saving design. The mesh frequency and high torsional rigidity of the gearbox are also extremely impressive since they ensure a higher degree of positioning accuracy and extremely smooth operation.

Product highlights

Consistently high performance

Constant backlash throughout the service life of the gearbox ensures a consistently high performance.

Low maintenance

Highest quality standards guarantee a long service life and extend maintenance intervals.

Machine Interface

Integrated slotted holes ease up the positioning of rack and pinion while increasing the overall system rigidity through the elimination of additional plates.

Forces

Reinforced bearings withstand the highest forces – while maintaining a compact design.

Compactness

The right-angle design allows for shorter machine concepts due to being short in the axial plane.

Positioning accuracy

Minimal backlash and extreme rigidity ensure maximum positioning accuracy at the tool center point.

Reliability

Extremely reliable gearboxes prevent cost-intensive machine breakdowns.
