Redex Andantex, two planetary gear units to save costs
REDEX ANDANTEX present KRPX, rack & pinion high-tech planetary reducers. KRPX is a cost saving and easy to integrate solution for moving column and gantry machine types.
Made of two planetary reducers, KRPX allows perfect mounting on both sides of the machine frame. The gearboxes are coupled with an electrical preload system enabling true zero backlash.
KRPX, the latest product development in the Racks & Pinions Drive range from REDEX ANDANTEX, is a true example of concurrent design between several Machine-tools OEMs leaders and one of their most strategic components suppliers.
To implement a TwinDRIVE solution (zero backlash with 2 servo-reducers and electrical preload) on a moving column or gantry machine was often complicated: It meant time for designing a new frame version, lot of money for making special tools, and many troubles to keep high precision machining on parts which are sometimes very large.
With KRPX, there is no need to design and integrate a high precision fixation extension to the main machine frame: that implementation is far simpler (easy integration) and cost-effective (up to 15% less expensive) than the conventional solutions.
The structure of KRPX housing has been optimised with FEM analysis methods to avoid deflection during acceleration. A very precise keyway machined on the mounting surface allows very easy setting while keeping perfect mounting geometry.
New REDEX system is available in the 3 standard universal sizes 2, 3 and 4; It is very compact, a definitive advantage for helping implementation with respective pinion height not higher than 104, 127 and 148 mm.
