Banded Belts

Because of their banded or joined
construction, these belts tend to prevent
rollover and reduce vibration tendencies

Banded belts are usually better suited to unusual drive
situations than are matched belt sets. They are available in the
Classical cross sections (A, B, C and D), Narrow cross sections
(3V, 5V and 8V) and Poly-V® cross sections (H, J, L and M).

Classical and Narrow Banded V-belts

Typical applications for Banded V-belts include vertical shaft
drives, clutching drives and V-flat drives. ( V-belt drives are
where the inside of the belt drives a flat pulley on the slower
speed shaft.)

Banded V-belts are recommended for use where belt vibration
or belt whip causes unsatisfactory results when conventional
multiple single V-belts are used. Such situations are not
uncommon on drives with a combination of long belt spans
and/or pulsating loads as created by an internal combustion
engine or reciprocating pumps and compressors. In such cases,
belt whip may become so severe that belts interface with each
other and turn over in the grooves or even jump out of the
grooves. Banded V-belts eliminate such problems.

Another advantage of Banded V-belts is the considerable degree
of design flexibility they can provide since they operate just as
effectively when they, in turn, are used as match sets. A two-belt
unit for example, has sufficient lateral rigidity so as to not
interface with the units in adjacent grooves.

Tor qu e Tea m Plu s® (aramid-reinforced
Banded V-belts)

These belts are available for low-speed, high-power applications
which were previously considered to be in the domain of chain
or gears. Aramid-reinforced Torque Team Plus® 5V and 8V
Banded belts are ideally suited to handle many of the
applications that have been reserved for chain or gears.

Poly-V® (V-ribbed)

Poly-V® belts are flat belts with a series of longitudinal ribs on
the driving face that mate with grooves in the sheave rim.
Relatively thin, with a well-supported tensile member, these
belts perform better than V-belts on drives with small sheave,
high speeds, reverse bends and high-speed ratios. Poly-V®
belts generally run smoother than V-belts and their low weight
makes them suitable for high-speed drives.

Three cross sections, designated J, L and M, handle the same
range of industrial applications as Narrow or Classical belts.
A smaller section, H, is used for small sheave and miniature
drives. Finally, the K section Poly-V® is of ten located in the
automotive industry.

Available in a wide variety of sizes

Continental ContiTech Torque Team® Laminated V-belts are
available in the 5VL belt cross section and in most standard
lengths. The 5VL laminated V-belt is interchangeable with all
standard 5V and 5VX V-belts currently found on these drives.
They can also be cut to a variety of rib widths, depending on
your drive requirements. This ensures a perfectly-matched set
of V-belts that can further enhance drive performance.

Reduce downtime and maintenance

Continental ContiTech Torque Team® Laminated V-belts can
withstand the punishment that results from jams in log and
lumber processing applications.

Standard V-belts resist slipping when a jam occurs, causing
excessive heat buildup that can lead to belt failure and costly
downtime. But that won’t happen with Torque Team®
Laminated V-belts on the job.

The special sidewall of Torque Team® Laminated V-belts acts
as a control switch, allowing the belts to slip as needed until the
obstruction is cleared. As a result, the superior wear-resistant
capabilities of Torque Team® Laminated V-belts are maintained,
increasing belt life up to four times longer than standard V-belts.

High strength for long life

Continental ContiTech Torque Team® Laminated V-belts feature
our powerful Vytacord® tensile members. Vytacord® provides
high strength and horsepower ratings, yet serves as a more
forgiving reinforcement that will give under excessive tension
instead of snapping. That means increased belt life.

the belt. The cushion is made of fiber-reinforced, engineered
compounds providing oil, heat, ozone and abrasion resistance.

Wedge or envelope constructions provide
optimum performance

HY-T® Wedge Torque Team® belts are available in a raw edge
construction with cogs for increased flexibility and heat
dissipation or envelope construction for drives where pulsation,
shock loads, high tension and long center are involved.

HY-T® Wedge Torque Team® cogged belts have high-horsepower
belt construction and are identified with a 3VX or 5VX prefix
and are available in lengths up to 140 inches. The cogged
construction provides the high flexibility required for short
center distances. The cogs also provide a larger surface area
to dissipate heat and prolong belt life. Improved material
properties and advanced construction technology result in
an average horsepower increase of 30% over standard joined
“Classical” V-belts.

HY-T® Wedge Torque Team® envelope belts are identified with
a 3V, 5V or 8V prefix and are recommended for drives where
pulsation, shock loads, high tension and long centers are
involved. They feature a continuous V-section that is protected
by a wide angle, synthetic fabric-impregnated, high-quality
rubber compound. The unique envelope achieves the high
strength that the HY-T® Wedge Torque Team® belts need to
withstand high loading forces. It also helps provide the torsional
rigidity in long center drives delivering the traction needed for
accurate tracking and precision performance.

Pulsation, vibration, shock loads and misalignment are problems
for any team of V-belts, no matter how perfectly matched the
individual units. These conditions often lead to chronic belt
whip or to belt turnover, resulting in premature wear or sudden
failure of one or more belts. Of course, when one belt goes, the
whole team has to be replaced.

Each rib in a HY-T® Wedge Torque Team® belt is free to wedge
into the sheave groove for maximum trac tion, maximum power
and transmission efficiency.

Operating in standard sheave grooves without sheave or drive
modification, they can tame any problem drives now in operation.
Or they can fit right in with your new drive designs without
special modifications.

Designed and built to deliver
superior performance

V-belt performance begins with the tension members, so we
built HY-T® Wedge Torque Team® V-belts with super strong
Vytacord.® It provides the high-strength, high-horsepower
rating capacity needed to effectively transmit drive power.
And it is tough enough to tolerate the misalignment that
quickly destroys belts. The Vytacord® material is a polyester
construction with excellent strength and minimal elongation.
Drive performance is consistent, reliable and predictable over
the life of the belt.

We then add a tough oil- and abrasion-resistant fabric backing
to provide maximum longitudinal flexibility and lateral strength
to withstand the dynamic forces acting within a joined belt .
The backing also has special adhesion characteristics that
enable it to bond to the V-sections to maintain the integrity of

Matchmaker® performance

Our Matchmaker® technology results in belt consistency run
to run. That means each HY-T® Wedge Torque Team® is equal
in size and performance to every other HY-T® Wedge Torque
Team® belt in that size, no matter when or where it
was produced.

By eliminating mismatch problems, there is no costly and
complicated belt matching to get a drive back on line; no
problems with belts that are too tight or too loose.

Available in the most extensive stock line
in the industry

HY-T® Wedge Torque Team® belts are available from stock in
any number of belts per team, up to the number of ribs
indicated. Nonstock lengths are also available in these rib
counts, up to a maximum of 730 inches (180 inches for
3V cross sections).
