KRP+ rack & pinion drive
KRP+ the 'KIT' concept
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 Rack & Pinion 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. In-Line and right angle versions are available.
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.
Two KRP+ reducers can also be combined together in an electrically preloaded TwinDRIVE kit. Backlash is eliminated using two motors, one to drive the axis and one to preload the axis.
