Premium V-Belt Drives

Premium belts have the highest power density of any V-belt, and stretch dramatically less than standard cross sections. That’s why they’re ideal for use on problem drives requiring high-impact strength and load-carrying power.

Premium Banded Belts
Replaces several belts with the strength of a single belt. Banded belts feature a multiple layer tie band that provides excellent lateral rigidity to prevent belts from turning over or from coming off of the drive.

Premium Single Belts
For applications when banded belts are not an option. Single belts can be used with deep groove sheaves and drives with limited room for “take up”. They can also be an “A” section solution for multi-groove A/B sheaves.

Premium V-Belt Drive Product Features

• “Clutching” non-rubber surfaced cover allows momentary slippage due to excessive overloads without burning belts up.
• KEVLAR* or aramid tensile cords give extraordinary strength, durability and virtually zero stretch.
• Virtually zero stretch eliminates the need for constant belt re-tensioning.
• Chloroprene rubber compounds provide superb oil and heat resistance.
• Specially-treated extra tough cover withstands slip and shear forces at peak loads without generating excessive heat; fends off penetration by foreign materials.
• Curve design compensates for effects such as sidewall bulge, which occur when
  belts bend around a sheave. This yields uniform loading, giving maximum belt life and even wear on the sheave sidewalls (eliminates dishing).
• Double fabric cover creates maximum abrasion resistance that protects against wear
  caused by fine airborne dust in rock quarries and lumber mills, which can cause rapid belt sidewall wear resulting in early failures.
• Over 20-50 percent more horsepower than standard V-Belts enables new equipment designers to utilize the full load-carrying capacity of these high-performance belts.

Narrow (Ultra V) Sheaves & V-Belts

TB Wood’s Narrow (Ultra-V) sheaves include three cross sections: 3v, 5v and 8v and are constructed of fine grain, high tensile cast iron and have been carefully engineered to assure maximum performance over a long life span. For applications with special requirements, Wood’s sheaves are also available on a made-to-order basis in either cast or ductile iron, in in Sure-Grip® or bored-to-suit construction.

Narrow (Ulta V) Sheaves & V-Belt Product Features

• Convenient Sure-Grip® QD type bushings

Classical (Conventional) Sheaves & V-Belts

TB Wood’s Classical (also known as Conventional) V-belts include five cross sections: A, B, C, D, and E. These sections are a continuing development of the original V-belts of the 1930’s. A, B, C, and D belts are available in wrapped or cog construction and all are static conducting, and oil and heat resistant.

Note: E section V-belts are available for replacement on existing drives, but are not recommended for new drive designs.

Light Duty (FHP) Sheaves & V-Belts

TB Wood’s light-duty sheaves are available in two types, both with one and two grooves. "AK" sheaves are made to accommodate A (4L) belts; "BK" sheaves are made for A (4L) or B (5L) belts. The two lines of sheaves have identical pitch diameters when using A or 4L belts. Wood’s light-duty sheaves can be equipped with Wood’s "QT" Sure-Grip QD-type bushings, quick-detachable tapered bushings that are split through flange and tapered surface to provide a true clamp that is comparable to a shrink fit.

Light Duty (FHP) Sheaves & V-Belt Product Features

• Easy-mount, Sure-Grip® Quick Detachable (QD) bushings
• Bored to size from 1/2 TO 1-1/2 inches
• Capacities to 15 horsepower

The K, L, and M sections are available on a made-to-order basis in either cast or ductile iron and in Sure-Grip or bored-to-size design.

SYNCRONIZE

QT PowerChain® II

The QT PowerChain II belt drive system from TB Wood’s consists of a synchronous belt, sprockets, bushings and idlers that are all designed to work together to deliver the best value in power transmission – whether the application is low-speed or high-speed. When compared with standard roller chain, this powerful belt drive system provides important performance advantages and significantly reduces overall costs. The new sizes of belts and sprockets along with increased power ratings (up to 40% higher than its predecessor) allow QT PowerChain II drive systems to be designed in widths narrower and more compact than ever before.

Product Features

• 8mm Pitch, Drive combinations: 66,600+, Speed Ratios: 336
• 14mm Pitch, Drive combinations: 51,500+, Speed Ratios: 500
• Operating Temperature Range: -65°F to +185°F (-54°C to +85°C)



Synchronous Plus

TB Wood’s Synchronous Plus synchronous drives offer the added flexibility of a dual sprocket design that features both metric and standard-tapped holes coupled with a high capacity Synchronous Plus belt. As a result, the Synchronous Plus drive offers a significantly higher horsepower rating at the standard industry price.

Product Features

Delivers 50% more HP capacity than standard construction high torque drives

Allows for use of smaller, lighter weight sprockets

Provides a more economical solution than standard high torque

Tensile Members Helically wound, "EXTRA STRONG" fiberglass cords are chemically treated and designed to assure superior length stability, maximum flexibility, and high tensile strength for shock loads.

Teeth and Backing Teeth are molded integrally with the backing that protects the tensile members. Both are manufactured from premium quality, synthetic, neoprene rubber that provides exceptional resistance to heat, oil, ozone, and flex fatigue. Precise tooth formation and accurate spacing permit smooth, uniform transmission of power with resistance to tooth jump and shear.

Wear Jacket The self-lubricating, nylon cover fabric construction is the key to the belt’s outstanding horsepower and torque rating. It not only assures maximum drive efficiency but provides exceptional resistance to tooth wear and shear from friction.

Dual Drill Many sprocket sizes are drilled for both inch and metric hardware.



Timing Belt Drives

TB Wood’s timing belt drives are a highly efficient job-proved medium for mechanical power transmission.
