Custom Pinion Stand Drive for Steel Tube Forming Mill
A major steel mill OEM required a custom gear drive for use on the pinion stand
that pulls steel coil through a tube mill which forms the steel prior to seam welding.
The OEM contacted Nuttall Gear based on their previous successful collaborations.
Nuttall engineers designed a custom drive that was properly sized to meet the
performance requirements while fitting within an extremely tight space limitation.
Driven by a 100 HP motor, the unique reducer consisted of two independent gear
trains, with 15" vertical offset center distance, enclosed in one housing. Each train
featured a reduction ratio of 46:1, a 1.5 service factor with 1150/2300 RPM input
and 25/50 RPM output. The drive also featured through hardened gearing and a
fabricated steel housing.
Nuttall was able complete all design, engineering and manufacturing within the
customer’s tight approval and delivery timeframes.
