1. Draw the gearbox with hollow shaft onto the machine shaft to be driven:
– Use a suitable assembly paste.
– Take up forces only via the hollow shaft, and not via gearbox housing.
2. Secure the gearbox axially:
– The hollow shaft is equipped with snap ring grooves for axial securing (fig. 3). Parts
required for fixing the shaft are not included in the scope of supply.
