BRECO®, BRECOFLEX® timing belts are manufactured of wear
resistant polyurethane and high tensile steel cord tension
members. Both high quality materials combined form the basis
for dimensionally stable and high resistance polyurethane
timing belts. Polyurethane timing belts have a very high span
rigidity. No post-elongation of the tension members is to be
expected in continuous operation. Only under extreme load
and after a short run-in time, the pre-tension of the belts
might slightly reduce by the tension members settling, making
a once-only re-tensioning of the timing belt unavoidable.
The timing belts are temperature resistant with ambient
temperatures from -30°C to +80°C. Applications close to
the limit temperatures (<-10°C and >50°C), however, might
require adapted dimensioning. For specifi c temperature
ranges various belt materials are available. Please contact our
distribution partner for this type of application.
The production methods according to which BRECO®,
BRECOFLEX® timing belts are produced, allow keeping within
tight tolerances which guarantee a uniform load distribution
during power transmission. These polyurethane timing belts
are suitable for the transmission of high torques as well as
the precise positioning and transport of various goods.
BRECOFLEX: The BRECOFLEX® timing belt is manufactured
in endless lengths without tension member interruption.
The tension member is spirally coiled. BRECOFLEX® timing
belts are universal applicable for all tasks in the drive
technology up to 10000 min-1.
Application areas
Endless timing belts for power transmissions
All drives designed for a high performance should preferably
be produced as BRECOFLEX® timing belts with a full length
steel cord tension member. They can be subjected to both
permanent operation or for a start-brake characteristic. They
operate in a rotational speed range of up to 10000 min-1.
Endless timing belts are available in preferred catalog lengths.
Our production range also permits the supply of intermediate
lengths up to a maximum endless length of 20000 mm.
StandardPlus - BRECOFLEX® timing belts with improved
properties
The new generation of BRECOFLEX® timing belts was special
developed for high precision positioning applications. The
use of the bifilar winding reduces the tendency of the belt to
run off. The special way of winding prevents the formation of
lateral forces resulting from the tensioned tension members
inside the belt, which cause the timing belt to run off. In
this manner, the friction forces in the drive are considerably
reduced which leads to improve positioning properties.
Additional the new BRECOFLEX® timing belts achieve a notably
improved pitch stability. The deviation of the tooth spaces
could be further minimized.
With the new generation of BRECOFLEX® timing belts, the
user is offered standard products which unite outstanding
properties, such as high power transmission, high rigidity,
optimized running behaviour and high precision.
