KRP+ the ‘KIT’ concept includes output flange mounting and integral output pinion which are dedicated to rack & pinion applications. KRP+ planetary reducers are the SingleDRIVE components in a family of reducers dedicated to Rack & Pinion and Rotary Table drive applications. They can be used alone as a single drive or combined with a second unit to create a ZERO-BACKLASH linear or rotary Axis. As A SingleDRIVE, the KRP+ features an integral output pinion and planetary gear train that have been optimized for minimum backlash (1 – 3 arc minutes) and maximum STIFFNESS ON RACK. DualDRIVE kit combines two KRP+ reducers in a patented, mechanically preloaded ZERO-BACKLASH system. The two units are torsionally preloaded against the rack in this closed loop mechanical system. Only one motor is required to drive the axis.

DRP+ DualDRIVE & TwinDRIVE includes monoblock housing for universal mounting. 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 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. DRP+ becomes a TwinDRIVE when the Electrical preload solution is applied to cancel the backlash. In this case backlash is eliminated by using two motors; one to drive the axis and one to preload the axis.

KRPX is a Side Mounted high performance planetary Servo-Reducer, dedicated to Rack & Pinion applications. The unique KRPX housing is designed to act as a RIGID MACHINE FRAME EXTENSION. The accessible side mounting offers a cost effective, easy to implement, high performance solution for both linear and rotary axis drives. Two units are combined together with electrical preload (TwinDRIVE) to create an extremely stiff ZERO-BACKLASH axis. The KRPX housing design has been optimized by finite element analysis to avoid deflection during acceleration and heavy loads. Furthermore, the output pinions are machined directly into the output shafts and supported by extra-large, preloaded tapered roller bearings to provide the best balance between transmittable torque and stiffness on the rack.
