Turnkey high class planetary Servo-Gearhead
Turnkey high class planetary Servo-Gearhead, dedicated to Rack & Pinion applications
The new benchmark for electrical preload on demanding machine tool applications! KRPX is the new version of REDEX ANDANTEX rack & pinion high-tech planetary reducers, offering cost effective, easy to implement and high performing solutions for moving column or gantry machine types as well as many other applications.
The KRPX housing is made of high quality spheroidal graphite cast iron. Its structure has been optimised with FEM analysis methods to avoid deflection during acceleration. Fixation is made by oversized screws to ensure a real still connection with the machine frame allowing the KRPX housings to be considered as an integrated part of the machine main frame.
The output pinions are machined to the same diameter as the shafts, allowing the best possible balance between transmissible torque and rigidity at the rack. In addition, output bearing consists of two preloaded and substantially oversized angular contact roller bearings.
This exclusive design offers exceptional compound stiffness which allows to dramatically decrease the radial bending (up to 60% of the overall distortion) and to increase the natural frequencies of the global Racks & Pinions drive systems.
Designed as an association of two high-tech planetary reducers, KRPX allows perfect mounting on both sides of the machine frame and enables true zero backlash when coupled with an electrical preload system.
Available in 3 standard universal sizes (2, 3 and 4) KRPX is very compact, a definitive advantage for helping implementation with respective pinion height not higher than 104, 127 and 148 mm.
