CAUTION!
A damaged gearbox must not be operated.
Before installing the gearbox, always switch off the machine and secure
it against a restart. In addition is has to be ensured that the machine
cannot move.
DANGER!
Death or extremely serious injury / crippling caused by moving machine
elements when accidentally switched on or by accidentally releasing
stressed components during assembly.
Before installation, check the direction of rotation of the gearbox. The
direction of rotation of the gearbox can be gathered from the data
sheet.
5.1
Mounting of the gearbox
The gearbox has to be securely screwed to the application. Special atten-
tion has to be paid to a flat support.
The centring collar on the output end of the gearbox housing can be
used for the exact centring of the gearbox. The dimensions as well as the
tolerances can be gathered from the data sheet.
All existing mounting holes must always be used on the selected screw-
on side. At this, the screw tightening torque depends on the strength
class of the screw as well as the material of the bearing face respectively
the internal thread. The thread reach has to be chosen according to the
strength class of the screw as well as the material of the internal thread.
5.2
Assembly of the output shaft
When mounting the output shaft, appropriate torque transmission must
be ensured. In the gearboxes of the HT and SHT series, a basic distinction
is made between solid shaft gearboxes (Figure 1) and hollow shaft gear-
boxes (Figure 2).
The assembly of these two variants is described respectively in the fol-
lowing chapters 5.2.1 for gearboxes with solid output shaft and 5.2.2 for
gearboxes with hollow output shaft.
