The NORD Screw Conveyor Package from NORD Gear Corp. (Waunakee, WI) offers closely stepped speed reduction ratios and a directly coupled gearmotor or NEMA C-face input design that eliminates the need for top motor mounts, pulleys, belts, or guards. Screw conveyor drive options feature a UNICASE™ reducer housing, Quadrilip™ reducer shaft sealing, and optional high-capacity output bearings with CEMA standard flange mounting and CEMA drive shafts ranging from 1-1/2" to 3-7/16".
The drive design is available for both CLINCHER™ Parallel Shaft gear units and Helical-Bevel Right Angle gear units. The CEMA flange assembly offers protection against unwanted debris with dual Viton™ gap seals (0.03" gap) on either side of the grease-filled felt packing seal. Drive shaft material evacuation ports in the flange help protect the drive system from debris. A slight lead taper on the reducer shaft provides for mounting and removal, allowing for some screw pipe misalignment and reduced bearing loads.
