Example
Floating pulley
on the cutting
equipment.
Bending in two
directions.
Noise.
Commercially
available belts
Designed to transmit
the power between
aligned, parallel and
fixed pulleys.
Designed to bend
around the pulley in
one direction only.
Made with no special
requisite for this
specific factor.
Genuine spare
belts
The genuine belt of
the PTO is designed
to function even if
the pulleys move up
and down and tilt
simultaneously.
Most belts installed
on machines have
tensioning rollers
which act on the
outer side of the
belt. This means that
during operation the
belt must bend both
inwards and out-
wards.
Genuine belts are
carefully selected to
limit increases in ma-
chine noise during
operation.
Chapter
5 Belts
Notes
The equipment
follows the ground
which means that
the pulley is in
constant movement.
To withstand
extreme operating
conditions, genuine
belts are made from
fibre reinforced
rubber.
All genuine belts,
which operate with
tensioning rollers
acting on the outer
side, are fitted with
reinforcement. The
reinforcement is
designed specifically
for these specific
cases.
Based on the
function of the belt,
any of the following
types of belt are
suitable:
• Coated
• No friction
• Open-sided
