Nuttall Spiral Bevel Right Angle Speed Reducers

Type TDS, Spiral Bevel Right Angle Speed Reducers are available in ratings from 50,000 to 5,000,000 inch-pounds of torque and gear ratios from 4:1 to 357:1. the input shaft is at a right angle to the output shaft, which may be horizontal or vertical shaft up and down. This provides flexibility in space utilization for typical applications such as material handling or cooling tower drives. These units retain the Type TDS design features, including tapered roller bearings and heavy duty cast iron or welded steel housings. Nuttall Gear can supply drives separately or as a packaged assembly with motor and reducer mounted on a bedplate.

Vertical Parallel Shaft Drives

Veri-Dri, Vertical Parallel Shaft Drives, are used for applications with higher power requirements, and are available with torque ratings up to 1,200,000 inch-pounds, and standard gear ratios up to 238:1. "Dry-well" construction, bidirectional shaft mounted lubrication oil pumps, oil flow indicators, and large inspection covers are standard features of the entire Veri-Dri product line. As with the smaller units, a wide selection of modifications and options, such as oil pressure switches, temperature switches, oil filters, immersion heaters, pressure gauges, and a choice of motor enclosures may be ordered to give you the right drive for your application.

Nuttall Right Angle Vertical Output Shaft

Type DRV and TRV, Right Angle, Vertical Output Shaft, gear drives are available with torque ratings up to 5,000,000 inch-pounds in gear ratios up to 238:1. Special output shaft bearings for down thrust, an oversized housing for maximum self-cooling thermal capacity, a shaft driven pump for force feed lubrication, and special corrosion resistant hardware and epoxy paint make this design particularly suitable for the most severe environments, such as cooling towers. In addition, this type of unit is also available with similar features, but with output shaft down and "dry-well" (zero leakage) construction. This configuration is most appropriate for chemical process vertical mixers, vertical pump drives and aeration drives.

Nuttall Horizontal or Vertical Extruder Drives

Type DHE / DVE, Horizontal or Vertical Extruder Drives, are available with torque ratings up to 600,000 inch-pounds and gear ratios from 6:1 through 25:1. This unit is available in case sizes for 2 inch through 10 inch extruder applications and can be mounted in the upright configuration or in the horizontal position. Standard construction includes all cast iron housings for quiet operation, integral thrust bearing, and a through bored output shaft for screw ejector or cooling. Custom output flanges and shaft dimensions are available to suit your air space adapter and screw shank requirements. In addition, Nuttall Gear offers "change gear" Type UE vertical and horizontal extruder drives with similar features and options, such as piggy-back motor mounts.
