Product Announcement from Andantex USA, Inc.
Andantex DRP+ planetary gearboxes are the dedicated solution to zero-backlash rack & pinion and rotary table drive applications.They consist of two top quality planetary reducers mounted in parallel inside of a super rigid universal housing. Two integral output pinions engage the rack to allow preloading of the system and maximize the stiffness on the rack. When choosing the mechanical preload solution, the DRP+ becomes a DualDrive unit, which achieves Zero Backlash by torsionally winding one pinion against the other through the rack. Only one motor is required to drive the axis simplifying motor control.
