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.
HY-T Wedge Torque Team belts are built with multiple belts
joined by a tough, rubber-impregnated fabric backing that
regulates belt travel so all ribs pull together as a single, perfectly
matched team. Yet each rib is free to wedge into the sheave
groove for maximum traction, 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.

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’s 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 the belt.

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˝. 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.

For shock load applications. Ideal for pulsating loads,
high capacity drives, and for short-center, heavy-duty
drives.

• Matchmaker® to eliminate mismatch.
• Static conductive.*
*Drive conditions and service variables in combination with time in operation can result in a loss of static conductivity. It is recommended that a conductivity check
be added to drive preventive maintenance programs where belt static conductivity is a requirement.
