Rack and pinion technology is making a
comeback
Micromech has developed the Alpha gearhead solution which combines a rack and pinion with the company's planetary allowing feed rates of 60m/min with acceleration rates of 5 m/s/s.
as more and more machine builders are turning to high precision rack and pinion systems for precision motion with extremely high levels of rigidity Available from Micromech is the Alpha gearhead solution combining a rack and pinion with their planetary allowing feed rates of 60m/min with acceleration rates of 5 m/s/s

Micromech appointed systems integrator for robots
Motoman Robotics (UK), Banbury, has appointed specialist motion control system builder, Micromech, based in Braintree, Essex, as systems integrator for articulated-arm robots.
In fact Alpha is one of the few global companies to offer quality level 5 rack and pinion systems that have a repeatability of less than 2 microns and a cumulative pitch error less than 2/3 of a ballscrew.
In addition to exceptional accuracy, these rack and pinion systems remain extremely rigid due to electronic pre-load.
It is expected with any Alpha gearhead there will be superb quality and these ranges are no exception.
They have a weight and space-saving mounting method through compact gear reducer design with integrated pinion and all mounting surfaces are ground to tight tolerances resulting in flexible mounting options.
The designers have optimised smooth and low noise level due to the pre-assembled gear pinion units with helix angle 19deg 31' 42", pressure angle 20deg and high concentricity (RTP version < 10 um).
Maintenance is minimised having high reliability because of wear-resistant surface treatment and individually de-burred gear teeth.
The clever compact, optimised design with its Low Mass moments of inertia results in maximum possible feed dynamics with short acceleration times.
The engineers have maximised precision for lifting axes, through the positive connection of pinion and a ultra-high linear accuracy because of minimum total pitch error (12 um / 500 mm).
The range also has maximum operational safety because of their high overload capacity.
