5.5.2.
Exchanging the toothed belt
Taking into consideration the technical axis data and boundary conditions, the
toothed belt used is maintenance-free and must not be changed.
Causes for abnormal toothed belt wear
Due to external influences or error applications, a toothed belt exchange might be
necessary. Causes for abnormal toothed belt wear are:
toothed belt tension too big or too small
impermissibly high drive torque, braking torque, or feed force
operating or ambient temperature too high
Contact with chemicals
A certain sign of wear may have different causes so that it is not always possible to
determine the exact cause. In case of abnormal belt wear it is recommended to
replace the belt and to check the application for the above mentioned "causes of
abnormal belt wear".

Assembling sequence
Dismantle and put aside the drive from the Linear actuator (see page 27).
After dismantelling the carriage lid, the frontal stop surface of the carriage is
sharp-edged. If handled carelessly during maintenance, you might cut yourself.
Protection gloves must be worn!
Dismantle and put aside steel strip cover, steel strip deflectors and steel strip
sliding rods (see page 43).
Take care when loosening or screwing in the round-head screws. Make sure that
the tool is axial to the screw and engages completely in the hexagon socket to
prevent damage to the screw head.
Loosen screws of the belt tensioning element Figure 15, Pos. 2) on both sides,
carefully pull out and put aside the toothed belt with the belt tensioning element
(Figure 15, Pos. 1) of the carriage (depending on the design, the belt tensioning
element is one-piece or two-piece).
Pull out belt on one axis side.
Clean the interior of the linear axis, deflection stations and carriage profile
(grease, abrasion, other impurities).
Cut the replacement belt to the required length using suitable sheet metal shears.
Use the old steel strip cover as matrix.
