Pulleys & Belts from Berges Antriebstechnik GmbH & Co. of
Marienheilde, Germany are now available for North America from TVT
America, Inc. TVT has long enjoyed a relationship with
Berges for the RGAE drive made with Berges Belts & Pullleys.
Realizing the unmet need for new & replacement pulleys & belts for
Berges equipped drives from SEW-Eurodrive, Nord, and other European
machines that are designed like our own reliable RGAE, we have fully
engaged in supporting this market.
America's location in the middle of North America allows convenient
2-day shipping via ground UPS or FedEx to nearly 80% of the market,
and our steady inbound air-freight shipments of service parts from
Europe for our range means we can deliver non-stocked items quickly
Pulley & Belt range is the refined perfection of belt driven
mechanical variable speed, they are used on a wide range of machines
in the food processing, petro-chemical, pumps of all kinds, metal
working, stone working, and this list goes on and one. Where
reliable, easy maintenance, and simple operation for variable speed
is required... Berges is a trusted solution all the way to 280hp.
are available in three principle designs:
Berges RF..b pulley is the
wide belt system that uses the R..b type pulley which has
adjustable pitch diameter as the control pulley on the motor
shaft, the F..b type pulley is provided with a tensioning
spring, and in constant center distance applications this pulley
automatically tensions the belt by adjusting its diameter to
complement the relative diameter of the R..b driving pulley.
This extremely reliable design can offer variable speed ranges
upto 10.5/1 and safely manage power to 225hp.
Berges RD..b pulley
system is also the wide belt system that uses the R..b type
pulley to control the pitch diameter and thus ratio of the drive
on the motor shaft. In the RD..b configuration, the D..b
pulley is an advanced design from
Berges GmbH that incorporates TLC (Torque Limiting Control)
by means of an integrated control cam that absorbs intermittent
overloading or torque peaks, and allows the output pulley to
function as a ridgid V-belt drive when locked. This
brilliant design yields a high degree of protection against
overloading and is especially useful in the higher power ranges.
The RD..b is available from 10 to 225hp and can offer ratios
upto 8.5/1 in some sizes. The RD..b uses the standard high
performance Berges Wide V-Belts
for ideal Variable Speed performance.
Berges KRM pulleys are ideal for
lower horsepower applications where a standard V-belt can be
used. The KR is mounted on the motor shaft or driving
shaft and functions as the control pulley, the KM pulley is the
spring loaded auto-tensioning pulley which is on the driven
side. This configuration provides constant center
distances, ideal tensioning, and a 6/1 variable speed range.
Power for the KRM series is between 1/2hp and 1.5hp, thus
serving a large section of light horsepower applications
requiring simple, reliable, low maintenance variable speed
control. The KRM can operate with standard metric belts in
sizes 10, 13, and 17mm width, and the
Genuine Berges brand belts are available from TVT America
for on-line purchase or standard purchase orders.
RF pulleys for standard v-Belts uses interlacing pulleys to
allow a wide speed range with the standard metric V-belts in
sizes 10, 13, 17, and 22mm. The interlacing pulleys
will allow speed change upto 8.5/1 in overall variance.
The RF series pulleys are available in several standard metric
bore sizes, and can handle horsepower from 1/2 all the way to
7.5hp. Genuine Berges
V-Belts are available from TVT America, as well as the R and
F pulleys for on-line purchase as well as purchase orders.
Pulley & Belt systems are used all over the world, there is a
wide range of accessories available from Berges GmbH to suit
your needs. There are easy to operate hand speed change
controls for the KRM, RF, RF..b, and RD..b series pulley systems
as well as remote mounted manual controls for the RF and RF..b
series pulley & belt systems.
course for a complete system, we offer the
enclosed Berges Belt & Pulley Drive system. From this
design we can control power from fractional to 225hp, manual
control, or electric remote control. Very large motors can
be easily tamed with the rugged & reliable RGAE system from
Varmec S.r.l. empowered with Berges Pulleys & Belts.
