XPK+ hypoid gearboxes

  • XPK+ hypoid gearbox with output shaft

  • XPK+ hypoid gearbox with pinion and slotted holes
  • Premium Linear System with XPK+ hypoid gearbox with slotted holes and innovative rack INIRA®

Power and precision in a compact design

The Premium planetary gearbox are now available in a right-angle version XPK+ 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

Productivity

Excellent torque density and rigidity reduce your cycle duration.

Low maintenance

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

Savings

The right-angle gearbox with very high breakdown torque capacity allows new machine concepts, for example a bearingless design.

Compactness

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

Reliability

Extremely reliable gearboxes prevent cost-intensive machine breakdowns. 

Process quality

Constant low backlash over the entire service life of the gearbox coupled with high torsional rigidity enables the highest levels of positioning accuracy.

Reinforced bearings

For absorbing high axial and radial forces

Output

Special XP+ output for higher power transmission 

Rearward output

Variable output connection, also rearward

Hypoid gearing

High-quality hypoid gearing for a higher torque and smoother operation

Metal bellows coupling at the input

Length compensation to protect the motor bearing

The XPK+ compared to the industry standard

XPK+ – Your Xtra productivity, precision and space saving

Are you looking for a gearbox far exceeding industry standards in terms of torque, breakdown torque capacity and torsional rigidity?
The XPK+ in the alpha Premium Line offers numerous technical benefits that improve performance several times over, for example with very short cycle times and optimal controllability of your drive axis. This compact “powerhouse” also gives you the option of reducing the installation space still further.
