Nord Drivesystems has released its Unicase Helical Worm Gear unit series to provide additional torque without modifying the outer dimensions or mounting patterns of the units. New worm shafts with larger bearing seats have been introduced to accommodate larger bearings and thus, higher power ranges. Advances include additional reinforcement of the worm wheel itself and a wider bronze gear rim. Prefabricated parts and hubs have been adjusted to widen sprockets, and consolidation of wheel sizes reduced the overall number of gear parts needed for the series, which also reduced the number of bushings needed. The updated line now offers a power range of 0.16-20 hp and a torque range of up to 17,700 lb-in. These units can be foot-, flange- or shaft-mounted with an option of hollow or solid shaft.
