Precision Manual Measuring or Scanning Device

A hand crank moved by a Macron counter-reversing drive provides smooth guided linear motion required for a precision measuring device.  The macro moves were achieved by pushing the slide into position while the hand crank coupled to a 10:1 gearbox provided micro-positioning for fine measurements with an integrated digital encoder.  Although applications such as these are often specified as a rack and pinion slide assembly, the belt drive solution offered greater flexibility and cost.
