2.3 Load bearing capacity of carriage and timing belt
The thrust force Fx the
timing belt
is capable of transferring depends on its pretension. If nothing other is indicated
the HPLA will be delivered with a standard pretension. With this pretension the HPLA is able to transfer the
nominal thrust force F_nom. If your application needs a higher thrust force the timing belt gets a higher pretension
and is able to transfer thrust forces up to F_max. If the force you transfer is greater than the pretension of timing
belt it can happen that the timing belt jumps on the pulley. The service life (s_nom. / s_max) of the drive chain
(without guiding system; with pulley mounted on gearbox shaft: bearing of gearbox), depends on the pretension
and the thrust force that occurs.
The forces and torques the
carriage
is capable of transferring is speed-dependent. The curves shown in the
graphs apply to a standard carriage (S/T). With the extended carriage (E/F) all the values apart from Fx (load-
bearing capacity of timing belt) can be doubled, if the load is applied equally to both halves of the carriage or
distributed uniformly along its entire length. The curves show the maximum load-bearing capacity of a carriage in
one direction of force or torque. If several loads are applied in different directions, the values given by the curves
must be derated
, i.e. the load or speed should be reduced if necessary. For the precise carriage dimensioning,
our software "DimAxes" is available (

The calculation of nominal service life for roller bearings bases on: at least 90% of all bearings achieve or exceed the nominal service life.
