A-A1. Modular Rack and Pinion System

This system consists of a standard range of straight, circumferential pitch, and helical racks and pinions. The modular design permits rack lengths from 0.5 meters to 2 meters to be linked end-to-end achieving any desired travel length from standard components. Racks & pinions are available with different materials, heat treatments and quality levels to ensure the correct balance of power, precision and price to meet application requirements.

The standard range is available in modules, M, 1.0 to 10.0 (Diametral pitch, P, 25.4 to 2.54) with lengths up to 2 meters allowing loads from 1lb. to 100,000 lbs. to be moved at speeds from 0 to 1000 ft/s (5 M/s). Rack lengths up to 4 meters (2 meters with ground teeth) and modules up to 20 are available on request.

Preloaded Rack & Pinion Drive Systems

The positioning requirements of today’s ultra-accurate CNC machine tools call for preloaded rack & pinion drives that i during acceleration, stead

Andantex offers 2 systems to achieve preload:

B. TwinDRIVE KRP+

Electrically preloaded TwinDRIVE units achieve the preload by “electrical braking” one pinion against the other. One pinion is considered as the driving pinion, while the other is braking.

This system requires two motors and a special motor controller to handle the preload.

C. DualDRIVE DRP+

Mechanically preloaded DualDRIVE units achieve the preload by torsionally winding one pinion against the other. One pinion is considered fixed and the other spring loaded.

This system is driven by only one motor and does not require any special motor controller. The preload is obtained with a REDEX patented preloading system.
