  • RPK+ hypoid gearbox with pinion
  • Premium Linear System with RPK+ hypoid gearbox and innovative rack INIRA®
  • Motor mounting alpha Advanced / Premium Line Right-angle gearboxes

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. 

Slotted holes

Integrated slotted holes reduce the design and installation requirements to a minimum

Hypoid section

High-quality hypoid section with gear ratios of i = 3 – 10 in the angle section

Metal bellows coupling

Metal bellows coupling incorporated for thermal length compensation and protection of the motor bearing

Pinion

The pinion are specially adapted to the gearbox and allow the transmission of extremely high feed forces

WITTENSTEIN alpha in all axes

Right-angle gearboxes

WITTENSTEIN alpha develops complete, single-supplier solutions for any driving axis. They can be used in virtually any application – from high-precision axes in manufacturing systems to packaging machinery where maximum productivity is required. 
The name WITTENSTEIN alpha is a byword for premium quality and reliability, high precision and synchronization accuracy, highest power density, a long lifetime and very simple motor mounting.
