• Type TDS, Parallel Shaft Speed Reducers, are available with torque ratings up to 4,500,000 inch-pounds, and standard gear ratios up to 1500:1. TDS units incorporate precision helical gearing (in single, double, triple, quadruple and quintuple reductions) enclosed in heavy duty cast iron or welded steel housings. Standard features include tapered roller bearings, large inspection plates, a positive splash system for lubrication, extra wide bearing spans and center bearing supports; all to provide a rugged reliable unit with proven dependability in virtually every industrial application. Nuttall Gear can supply TDS units separately or in a completely engineered package including motor and reducer mounted on a bedplate.

• Type TDS, Spiral Bevel Right Angle Speed Reducers, are available in ratings from 50,000 to 4,500,000 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 or 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 bearing.and heavy duty cast iron or welded steel housing Nuttall Gear can supply drives separately or as a packaged assembly with motor and reducer mounted on a bedplate.

• Type UE, Upright Extruder Drives, are available with torque ratings up to 375,000 inch-pounds and changeable gear ratios from 6:1 through 25:1. This change gear unit is available in case sizes for 2 inch through 6 inch extruder applications and can be mounted in the upright configuration or in the horizontal position. The ability to easily change ratios permits the adjustable speed portion of the drive to operate in its optimum range, yet maintain production and/or material speed requirements. Standard construction includes all cast iron housings for quiet operation, integral thrust bearing, 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.

Veri-Dri, Vertical Concentric Shaft Drives, are available with torque ratings up to 230,000 inch-pounds, and output speeds from 1.5 to 780 RPM. Veri-Dri models are available as gearmotors, both integral construction and C-face mounted, or as reducers. All types utilize "dry well" construction to prevent possible oil contamination in the product or process. They are well suited for water treatment, food processing, and chemical duty; on aerators, mixers, agitators, and blenders. Cast iron housings, bi-directional shaft mounted lube oil pumps and oil flow indicators are just a few of the features that make Veri-Dri gearmotors and reducers rugged and reliable performers.

• 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, bi-directional 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.
• Type DRV and TRV, Right Angle, Vertical Output Shaft, gear drives are available with torque ratings up to 1,200,000 inch-pounds in gear ratios up to 40:1.

  Special output shaft bearings for downthrust, 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.

• Type R, Moduline® Concentric Shaft Speed Reducers, are available with torque ratings up to 233,000 inch-pounds, and standard gear ratios up to 985:1. Type R drives incorporate precision helical gearing in single, double, triple, or quadruple reductions. Standard features include rugged cast iron housings, and tapered roller bearings. Millions of hours of field operations have made the Type R-Moduline the standard for industrial applications. These heavy duty reducers are well suited for use with any prime mover - AC or DC motors, gasoline or diesel engines, power take off shafts, and line shafts. Optional modifications might include special ratios, taconite seals, backstops, bedplates, or special output shaft dimensions to meet your exact requirements.

• Type G, Moduline® Integral Gearmotors, are available in ratings from 1 to 200 HP and output speeds from 1.5 to 1430 RPM with AGMA Class I, II, or III service factors. This compact integral design, pioneered by Nuttall Gear, fits many applications and provides total drive source responsibility for motor and gear application and performance. AC motors, both standard and high efficiency, and DC motors are available in all enclosures. A complete range of optional motor modifications can be supplied to tailor the Moduline Gearmotor to your exact requirements. Cast iron housings and tapered roller bearings are standard features of the gear boxes. Special shafts, seals, slide rails, brakes, and a variety of mounting positions are available with this versatile Gearmotor design.
