17Q10H14WP Cast Iron Worm Gearbox

Tigear® stands for “Tough Industrial Gear”

The Tigear-2 reducer is built with the uncompromising Dodge® design standard to provide long life in demanding industrial applications. After decades of proven field experience, side-by-side testing in our advanced lab demonstrated its best-in-class durability over the competition.

The rigorous testing compared three brand-new gearboxes from each of the three manufacturers. Each gearbox was a two-inch center distance, a 15:1 ratio, and used the manufacturer’s highest quality oil offered (the standard for Dodge is the highest quality offering). All units were tested at an output torque of 1,580 lb-in, which is equivalent to the following ratings for each gearbox: 200 percent for Tigear-2, 197 percent for Competitor B, and 179 percent for Competitor C.

Testing was performed for 500 hours or until gearbox failure, whichever came first. Once testing was complete, each unit was disassembled for evaluation with inspection of individual components.

Features and benefits

• 12 case sizes
• 1.33” to 4.75” center distances
• 5:1 to 60:1 reductions
• Quill input
• Separate input
• 3-piece coupled input
• Solid output
• Hollow output

On average, Tigear-2 delivers more torque than competitive, same-sized models. This permits downsizing and helps reduce total cost of ownership.

Tigear-2 reducers share the same footprint and most critical mounting dimensions with original Tigear and many competitive models.

Configuration options

The advanced design concept of the Tigear®-2 reducer product line provides extreme flexibility for applications that require from 100 to more than 6,800 lb.-in of torque. Whether the application requires the compactness of a quill-style input, the durability of a 3-piece coupled input, or a separate keyed input shaft for belt-driven equipment, Tigear-2 is the answer. With four basic reducer configurations that are dimensionally interchangeable with most competitive brands and stock bolt-on accessories, the Tigear-2 reducer line is truly a complete line that is full of value.

Quill input

Space-saving quill-style input reducers for NEMA C-face motors are in both solid and hollow output designs.

Separate input

Separate style input reducers with solid or hollow output shafts are suitable for either belted or direct-coupled motor connections.

3-Piece coupled input

Attaching a stock, 3-piece coupled motor adapter kit to a separate style reducer creates a durable drive package that facilitates easy motor removal and provides protection against shock loads and other unpredictable vibrations.

Tigear-2 sealing system

The totally enclosed, ventless sealing system operates effectively with no pressure vent, no compression chamber. Tigear-2 contains a factory-filled synthetic lubricant that runs cooler, as well as eliminates the need for routine oil changes. All reducers are filled with the proper amount of lubricant for any approved mounting position. Simply install it, then forget it.

Special hydrodynamic wave seal design

The special wave shape (molded into the seal lip) generates a better hydrodynamic film, which is required between the seal and the shaft for long life. This special wave design generates less drag, less heat, and virtually eliminates shaft grooving created by the single-point wear track, which is common with conventional trimmed lip seal designs. The sinusoidal lip of the wave seal effectively pushes external contaminants away and pumps lubricant back into the oil sump.

Special lip construction

Optimized lip-to-shaft contact pressures ensure maximum life. In addition, special sealing elements operate under pressure without detrimental effect on service life or sealing performance.

Factory-filled synthetic lubricant

The standard synthetic lubricant used in Tigear-2 meets H1 food grade requirements and accommodates a wide range of operating temperatures. In extensive laboratory tests, it lowered operating temperatures by 20°F over other popular synthetics. No routine scheduled oil changes are required.

Locking system

The Tigear-2 reducer's Grip Tight tapered bushing system uses concepts that have proven to be effective in the locking mechanism of the Dodge® Grip Tight bearing to simplify installation and removal as well as prevent fretting corrosion problems. There are no loose fasteners to misplace during installation, and the locking nut creates a positive means for easy removal.

Minimum shaft length

The system's tapered bushings allow for mounting in some of the tightest places on almost any size shaft. (Driven shafts need not protrude completely through the reducer bore.)

Bushing options

When used in pairs, the tapered bushings can be used without output keys. Corrosion resistant options are available for severe washdown applications.
