Timing Belt Conveyor
Application Options
Timing belt conveyors are ideal for the cycled transport
of products. Available with different drive options
and as a single, double or multiple line conveyor,
they are often used to construct complex
interlinking solutions. The double-line solution is
frequently used for transporting pallets. In such
applications, timing belt conveyors are used when
high speeds and accelerations are required. Chain
conveyors and accumulating roller chain conveyors
are used for high loads (see the image on the left
and the next chapter).
Our range of different timing belt materials allows
you to find the optimal grip for the workpieces in
your specific application. Options include aluminium
timing belt pulleys, anodised timing belt pulleys and
stainless steel timing belt pulleys (for reducing wear
while improving corrosion resistance).
The timing belt conveyor ZRF-P 2040 is predominantly
used as a single-line solution. Cams or threaded
sleeves can be welded onto or preferably bolted
onto the timing belt for product take-up. For boltedon
cams, the AT timing belt is used due to the wider
tooth shape. In addition to greater tooth rigidity and
the larger load contact surface, this provides the
necessary space for plug-in threaded sleeves. As a
result, the system is also suitable for precisely feeding
and positioning loads weighing up to 250 kg.
As a double-line system, ZRF-P 2010 timing belt
conveyors are ideal for the cycled transport of pallets
or products with a rigid structure. Combined
with the wide range of drive options, the system is
the perfect basis for constructing complex interlinking
and automation systems. The timing belt returns
inside the profile allowing for a compact design and
which reduces the risk of accidents to a minimum.
Timing Belts
The standard timing belts are made from polyurethane
reinforced with high-strength steel cords.
The belts in the 2010 system have the T10 partition
and are up to 32 mm wide (others available on
request). To ensure optimal transport, different
surface coatings can be used (see page 172).
A coating on the teeth side (PAZ = polyamide toothside)
is recommended, especially for conveyor
speeds above 30 m/min. Since standard timing
belts with the PU base material on the teeth side
tend to produce noise when passing over the aluminium
timing belt pulley a PAZ coating, in addition
to good lubrication, is a reliable solution to this
problem.
The PAZ coating takes the form of a nylon fabric on
the teeth side and is also available in an impregnated
version to meet ESD requirements. This use of
this nylon fabric in cleanroom applications is controversial
because of the fine abrasion particles it
produces. Many of our customers prefer the larger,
visible particles produced by the PU base material.
We can also provide a conductive base material on
request for use with electronic parts and in explosive
atmospheres.
