helical-toothed sprocket wheel / double / preloaded

Dedicated to racks & pinions drive applications, the DRP+ design is based on the association of two top quality planetary reducers, mounted in parallel on an extra high stiffness universal frame. When choosing the mechanical preload solution, the DRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack. Immediate benefits are to need only one motor, and to dramatically simplify the motor control. When choosing the Electrical preload solution, the DRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.
