Amacoil Introduces Traversing Drive Assembly
Aston, Pa.-based Amacoil Inc., the North American distributor and service/parts provider for Uhing
linear drives and assemblies, now offers a traversing drive assembly that automatically adjusts
stroke length when winding materials onto spools with tapered flanges, eliminating the need for
programming or electronic controls. As the drive nut traverses back and forth, a cam attached to
the drive actuates a ratchet mechanism linked to the end stops, adjusting the spacing of the stops
in specific increments preset by the user. The stroke length adjusts in accordance with movement of
stops. The linear pitch may be adjusted without changing gears or motor speed.
The traverse drive's pitch control lever enables variable linear pitch with a 10:1 turndown range. Amacoil stresses that if roller guides or other devices mounted to the traversing unit cause moments of overturning force, users should use a linear bearing slide load carrier to support the load. The company also notes that the traverse shaft must rotate at a minimum speed of 10 revolutions per minute, and the assembly's drive shaft must rotate only in one direction. Maintenance is minimal, consisting only of occasional light lubrication of the shaft.
