Efficiency and energy savings The small bending cross section of the flat belt
causes little bending loss and only slight deformation
work (flexing work). This fact, together with even running
and the absence of pulley wedge effects, leads to a higher
flat belt efficiency as opposed to the open - flank, toothed
space saver V-belt, in spite of the fact that the space
saver belt referred to herein is the most efficient among
the various types of V - belt. Minimal maintenance Energy Efficient Flat belts keep their uniformly high tension
force throughout their service life and thus need no maintenance,
whereas V belts have to be checked and retentioned from
time to time. Once the Energy Efficient flat belt drive has been
correctly installed, it is maintenance free (apart from
usual control checks) and guarantees constant power transmission
during its entire service life.
