Installing the planetary gear unit

For installation of the planetary gear at the stepper motor please note the following:
• The planetary gear of the AG1000-xxxx series are supplied with a separate adapter shaft and
integrated sun wheel.
• Slide the adapter shaft onto the stepper motor shaft up to the end stop and secure it with a heat
resistant, industrial adhesive (e.g. WEICONLOCK AN306-60).
• Before applying the adhesive to the adapter shaft, clean the motor shaft with a suitable solvent.
• A cotter pin (not included) can be inserted through the mounting hole.
• Slide the gear unit onto the motor shaft. Screw the gear flange to the motor flange. Ensure the screws
are tightened evenly to avoid tensions in the component.
7.2.1

Mounting the gear

Order of assembly:
• Clean the motor shaft and the sun wheel with isopropanol. Remove all dirt particles from the motor
shaft or sun wheel. Carefully dry all the components.
• Wet the sun wheel and the motor shaft with the adhesive WEICONLOCK AN 306-60. Make sure that
the adhesive is evenly distributed over the complete motor shaft.
Damage to the gear unit!
When wetting the motor shaft, make sure that no adhesive runs into the interior of the component! There is
a danger of components sticking and impairing the function of the gear unit!
Hardening time of the adhesive!
WEICONLOCK AN 306-60 is an anaerobic adhesive. It hardens immediately on contact with metal
and the exclusion of oxygen. Note that the components can no longer be moved after gluing. The
adhesive is completely hardened after 10 to 15 minutes.
• Now wet the threaded holes of the gear unit with a screw-locking compound. Make sure that all threads
are completely wetted.
• Push the motor onto the gear unit and fix both components.
• Now fasten the gear unit to the motor with the four hex socket-head screws. Tighten the screws
diagonally. Observe the specified tightening torque.
