Level winding drive option

Aston, Pennsylvania – Amacoil Inc. now offers an option on Uhing rolling ring level winding drives which enables users to spool cable and other materials with specific spacing between rows. The standard drive creates a smooth, even, level wind with adjacent rows of material. The option – a set screw inserted into one or both ends of the drive housing – allows measured spacing of spooling rows. No complex electronics or programming are needed.

 

On a standard rolling ring level winding drive, the pitch is set using the pitch control lever on the unit. Setting the pitch determines the linear speed at which the drive will move along the shaft. The pitch is usually set to match the diameter of the material being spooled in order to form adjacent rows on the reel.

 

With the set screw option, one end of the screw protrudes into the drive unit housing. The end of the screw contacts the rolling ring assembly and holds it at a specific angle relative to the shaft. As a result, the drive will begin travel across the shaft at the pitch lever setting, but after reversal, it will travel back at a higher or lower speed depending on the set screw adjustment. This creates equal spaces between the rows of material being spooled. No adjustments to motor speed or other controls are necessary. Machine designers will find the Amacoil set screw option an effective, low cost solution for spooling applications that require special spacing of rows on the take-up reel. 

 

If two set screws are used, one in each end of the drive housing, the drive unit moves at pre-selected fixed speeds in each direction of travel. In this case, the adjustable pitch control lever is removed. The speed in each direction of travel may be set the same or different depending on the winding pattern required.  

 

Amacoil representatives will work with customers to determine the correct settings for the set screw to achieve the desired layline spacing. The set screw option is available on new units and readily retrofitted to existing Uhing winding drive set ups. Once the set screw is in place it should not be changed by the user. Changing the depth at which the set screw is installed will change the travel speed of the drive unit. 

 

Amacoil Inc. is the exclusive North American distributor of Uhing rolling ring linear drives and assemblies used in linear motion applications including winding of materials from hair-thin wire to heavy gauge cables, ropes, and chains. Rolling ring drives are an alternative to screw-based drives that run on a smooth shaft without threads, which reduces the potential for clogging and jamming.
