REDEX patented DualDrive and TwinDrive preloading technologies give CNC machine designers several ways to build a zero backlash system. These approaches leverage Redex modular SRP, DRP, KRP, and KRPX Series rack-and-pinion reducers, whose output pinions are preloaded against the rack to eliminate backlash — a challenge with designs that require long-axis travels and positioning over the entire length of travel to less than 0.001 inch.
Redex-patented DualDrive systems achieve a mechanical preload by torsionally winding one pinion against the other when both pinions are in contact with the same rack. DualDrive needs just one motor, and no special controllers are required.
TwinDrive technology electrically brakes one pinion against the other (driving) pinion when both pinions are in contact with the same rack. These systems incorporate two motors and gearboxes for use with CNC control.
Redex SRP, DRP, KRP, and KRPX Series rack-and-pinion reducers, together with DualDrive or TwinDrive technology, let machine designers create zero-backlash preloaded systems that achieve precise positioning and improved stiffness in CNC applications. These reducers feature optimized radial and torsional stiffness, very high linear accuracy, compact sizes and precision geometry for meshing with the rack.
