Vogel rack and pinion drives achieve linear motion for short up to long strokes with high accuracy and easy installation.  There are three parts:

-a low backlash Vogel planetary gearbox with torques up to 850Nm and ratios 3 to 100.
- a precision ground rack supplied by partner WMH Herion available in sections of length 0.5 to 2m or as specials.
- a precision pinion fitted to the gearbox with a keyway or a splined connection for lowest backlash of 1 to 3 arc mins.

Gearboxes can be supplied with AC motors, either standard asynchronous or servo. Type MPRN has an output with keyway and suits most applications.  Type MPRW has a splined output for reduced backlash suiting positioning with micron accuracy.

These rack and pinion drives give linear speeds from 0.1 to 6.5m/s.  They suit machine tools, robotic handling, gantries and other linear motion requirements.  The stroke can be created from several pieces of rack that are joined with special mounting pieces. Automatic lubrication systems are available for long life.
