Alpha Introduces High Precision Rack & Pinion System



Elk Grove Village, IL - alpha gear drives, Inc. introduces its new precision rack and pinion system, offering maximum possible feed dynamics with short acceleration times because of its compact design and low mass moments of inertia. A high-precision, compact alpha gear reducer or gearmotor with integrated ultra-high accuracy pinion and rack provides an economical weight and space-saving alternative to precision ground ball screws and linear motors, offering better performance for less money, especially in travel lengths over 1 meter. Further cost savings are realized by the elimination of the moving tracks and cooling apparatus required by linear motors. A bonus is the elimination of metal chip contamination, always a problem with linear motors.

All rack and pinion mounting surfaces are ground to tight tolerances, providing the user with flexible mounting options. The rack is easy to install in limitless lengths with no extra set-up procedures required. Standard rack lengths of 167 to 500 mm are available. The product offers ultra-high linear accuracy due to minimum total pitch error of 12 µm per 500 mm of length. Load capacities up to 13,000 N are available.

Either an automatic lubrication system or dry-lubricated gears are available. Wear-resistant surface treatment and individually deburred gear teeth provide high reliability.

Pre-assembled gear pinion units with optimum helix angle and high concentricity provide optimized smooth running and a low noise level. Maximum precision for lifting axes is provided through positive connection of the pinion. Maximum operational safety is assured because of the product's high overload capacity.
