Winding Drive suits general spooling applications.

Press Release Summary:

Uhing Model RGK3-20-0 rolling ring, traverse winding drive uses injection-molded plastic parts for housing and rolling ring carriers. It offers 110-130 Newtons axial thrust due to bearing assembly design where all 3 thrust rings pivot instead of one. Release lever enables user to slide drive freely on shaft without turning on motor. Linear pitch control mechanism is continuously adjustable from 1.0-12 mm, eliminating restrictions of stepped pitch control design.

Fewer Parts, Economical Design -- New Uhing Winding Drive is for General Purpose Spooling and Winding

Aston, PA, January 2005 - Uhing has introduced the new Model RGK3-20-0 rolling ring traverse winding drive for general spooling applications. Manufacturing economies in the Uhing RGK3-20 include fewer parts than standard Uhing drives and the use of injection molded plastic parts for the housing and rolling ring carriers. These economies permit competitive pricing, yet do not impair the drive's ability to meet application requirements for most basic level winding operations thereby providing an economical alternative to other traversing devices.

The RGK3-20 drive offers 110-130 Newtons axial thrust which is higher than comparable general purpose rolling ring traverse drives typically providing about 70 Newtons of thrust. The higher thrust in the RGK3-20 is due to a bearing assembly design where all three of the thrust rings within the unit pivot instead of one.

Standard on the RGK3-20 drive is the Uhing F option which is a release lever enabling the user to slide the drive freely on the shaft without turning on the motor. This feature is useful in reducing wear and tear on traverse system motors. Because the RGK3-20 center ring carrier is not connected directly to the mechanical reversal lever, as it is on standard Uhing drives, the new drive may not be configured with the usual Uhing mechanical motion control options such as ramp down, dwell and ramp up.

The linear pitch control mechanism on the new Uhing drive is continuously adjustable from 1.0 mm through 12 mm. This removes the restrictions of a "stepped" pitch control design where users are limited to adjusting pitch in a limited number of fixed settings. Tested for more than 50 million switch cycles, the RGK3-20 rolling ring drive requires only minimal maintenance -- occasional shaft lubrication (four times a year).

The RGK3-20 drive is a genuine Uhing drive and includes the service and support package offered for all Uhing products. Additionally, Uhing distributor Amacoil (Aston, PA) provides technical support, parts and repairs for the North American market. In some cases Amacoil will also visit users in the field to provide on-site assistance.
