TRANSDEV SPECIAL BELTS
Polyurethane Timing, Conveying and Indexing Belts
On-site Mechanical Assembly
On-site mechanical assembly
TransDev joined Polyurethane belts are welded in our Poole factory
using specialised equipment and tooling. Whilst our own in-house
joining facility is not portable, we have developed two joining methods to
enable on-site assembly, where the belt can be joined whilst in position
on a machine. A system can now be designed where an endless belt can
be fitted into otherwise difficult surroundings, where the installation of a
pre-joined belt would be time consuming, awkward or impossible.
The advantage of the many hours saved disassembling and reassembling
a complex machine to replace the timing belt is obvious. In some cases
it is only possible to design timing belts into a system if on-site joining
is possible.
Other Belts
Pin jointing
The first method, ‘pin jointing’, utilises pins
which are inserted into prepared holes in
the belt teeth using a special tool, which we
have developed for the purpose. Assembly
is reasonably straightforward using the
instructions supplied. We estimate that
assembly will take approximately 10 minutes
after the cut ends of the belt have been
positioned ready for joining. There should
be some means of adjustment to allow the
belt to be tensioned after joining. It should
be noted that the load figures of ‘pin jointed’
on-site assembled joins are reduced when
compared to normal welded joins. Each tool
is designed and manufactured specifically for
each pitch and width, so multiple tools would
be necessary for machines using varying sizes.
Only certain pitches and width combinations
are available, as listed in the table below.

On-site welding
We can provide an on-site welding
service where a belt is heat welded
by our engineers to the same
standard as those joined in our
factory, the finished product being
identical to a “BRECO® V” belt
supplied ready joined.
After initial inspection of your
machine to determine what
on-site welding tooling is required
from our existing extensive range,
the belts are prepared for joining
in our factory and installed on-site
by our engineers. We will also need
to assess services during our initial
visit, to ensure that our equipment
will operate correctly. The service
can be completed outside of
normal working hours, on bank
holidays or at weekends if
required, reducing the
inconvenience of belt replacement
during production time.
Any belt pitch and width available
in the normal joined range may
be supplied, providing there is
sufficient room to access the belt
for joining.
For further information about any
of these on-site assembly services,
please contact our Technical
Department, who can advise the
suitability of the service and
discuss any specific requirements.
