The Harrison, Hogenson, and Campbell teams worked together to specify, size, and select NORD gear reducers and NORD MAXXDRIVE® industrial gear units. NORD application engineers then worked directly with the various world-class USA manufacturers who would eventually provide the mill systems and equipment, in order to provide guidance on design, assembly and commissioning.
NORD’s Helical Bevel gear units,
CLINCHER™
Parallel Shaft gear units, and
MAXXDRIVE®
industrial gear units offered several product advantages for Harrison.
The NORD solutions eliminated the need for outdated shives/pulleys/belts/guards, etc. They also use a direct-drive concept that is much safer and more efficient. It was also more cost effective for Harrison due to reduced maintenance and service requirements commonly attributed to belts and pulleys. Fewer moving parts also enhanced the overall reliability and reduced the number of wear parts that needed to be stocked.
For this project, all NORD gear units from 3 HP to 200 HP were equipped with NEMA input adapters for ease of motor replacement. Over 75 different NORD selections were used on the Harrison feed mill project ranging from 4,000 lb/in to 500,000 lb/in torque. NORD’s extensive product offering was also a key factor in the decision-making process and allowed Harrison to consolidate all requirements to one key vendor partner.
