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.
Torque Team Plus
®
(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 often located in the
automotive industry.
