HaydonKerk Motion Solutions Introduces Custom Lead Screws for Transportation Applications

HaydonKerk Motion Solutions (http://www.HaydonKerk.com), one of the world's premier manufacturers of non-ball Lead Screws (http://www.kerkmotion.com/products/lead-screw/lead-screw.asp), is offering its custom Kerk® Lead Screw and nut for Automatic Door (http://www.kerkmotion.com./default.asp) actuation used in Transportation (http://www.kerkmotion.com./pdf/news/Transportation.pdf) applications. The product, available in both standard and custom configurations, was adapted for use in a variety of Transportation-related applications, including mass transit vehicles, such as subways, trains, and trolleys.

The Kerk® Lead Screw assembly requires no routine maintenance and offers a high degree of accuracy and dependability. Economically priced, the assembly is designed for extremely long life: it has been customer tested to more than 1 million cycles.

The screw and nut combination includes a precision-rolled, stainless steel Lead Screw and a custom-formulated, high-strength, self-lubricating Kerkite® polymer nut. The Lead Screw, available in lengths up to 12 feet, is offered in both right- and left-hand thread in a variety of leads (including back driving leads), up to three inches per revolution.

--    Kerkite® polymers outperform other plastics and outlast metal bushings and bearings

In a typical Transportation application, the doors are opened and closed by the motor-driven screws. In some instances, (i.e., a set of subway doors where the two door halves meet in the middle) each door leaf has its own motor and Kerk® Lead Screw to open and close. The Automatic Doors utilize software and motor synchronization to achieve simultaneous movement. In other cases, a single Kerk® Lead Screw can be used where both doors ride on their respective half of the screw. The Lead Screw is RH on one side and LH on the other, so that turning a single motor in one direction allows the two Automatic Doors to move in opposite directions.

--    Lead accuracies are available to .0001 in./in. with optional individual screw mapping

The Kerk® Lead Screw is currently in use in Transportation-related applications in North America, Europe, and Asia.
