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 attention has to
be paid to a flat support.
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.
5.2
Assembly of the shafts
The torque transmission takes place via a key. The shaft is suitable for mounting cou-
plings or for a direct mounting of transmission elements such as gearwheels or belt
wheels onto the shaft.
The gear shaft must be clean and free of grease or oil.
For the chosen transmission principle, the existing specification of the manufacturer
of the coupling or the clamping device must be observed.
NOTICE
Damages of the gearbox caused by large axial loads during the assembly.
When pressing components onto the shaft, do not support the force via the gear-
box housing.
The supporting length of the key must be suitable for the torque to be transmitted.
5.3
Assembly of the motor for the BF series
The torque transmission of the motor also takes place via a key. The hollow input
shaft of the gearbox as well as the solid shaft of the motor must be clean and free of
grease or oil.
