Control doubles linear pitch accuracy of heavy-duty traverse drives

An upgrade of large sizes for a line of traverse drives — by adding a 100-notch scale to the pitch adjustment control, doubles linear pitch accuracy — facilitates more precision in incremental linear movement. Now, the RG50, RG60 and RG80 drives from Uhing have a 10:1 linear pitch range which is adjustable over one hundred discrete notched settings. Moving the pitch control lever one notch up or down changes pitch by 0.01. Previously, moving the pitch control lever resulted in only a 0.02 change in linear pitch. The upgrade means that now all Uhing traverse motion drives have the more accurate 100-notch linear pitch scale. A worm gear option is available by which the notched pitch settings are bypassed and linear pitch is infinitely adjustable (over the 10:1 range) using a control knob. Large Uhing RG traverse drives from Amacoil provide from 225 to 800 pounds of axial thrust and are primarily used for traverse winding of thick cable, heavy rope and chain onto wide, large diameter flanged spools and reels. RG drives are also used for linear motion in packaging and converting equipment, and in other production machinery requiring a reciprocating linear motion component. The Uhing RG traverse winding drive is a friction drive which must run on a case hardened and precision ground shaft. Amacoil offers RG drives separately or in an assembly complete with shaft, pillow block end supports, bearings and adjustable end stops. Assemblies are custom built to meet customer requirements. As the exclusive North American distributor for Uhing rolling ring linear motion products, Amacoil provides sales, technical support, service and parts.
