5.2.3 Mounting the motor on a gear unit with ME/MEL/MF/MFL adapter
This chapter describes the assembly of a motor on a STOBER gear unit with an ME/MEL/MF/MFL motor adapter.
Prerequisites
§ Dimensional tolerances of the motor correspond to the requirements in the chapter Tolerances for the add-on motor
[}16]
§ The permitted tilting torque on the gear unit input is not exceeded (see Permitted tilting torques at the gear unit input
[}16])
§ Four screws of strength class 8.8 are available for mounting the motor on a gear unit. The minimum screw depth for
these screws is 1.6x the nominal diameter of the screw
§ The necessary tools and aids are available (see Installation [}15])
§ The information in the chapter Cleaning agent and solvent [}15] is observed
Procedure
In order to prevent unfavorable shifting or tilting of the motor shaft, STOBER recommends mounting the motor on the gear
unit with the motor shaft pointing down vertically.
1. Position the gear unit (5), if necessary with the aid of lifting gear, so that the motor can be mounted in a vertical
position.
2. Remove the transport cover of the motor adapter.
3. If a feather key is installed on the motor shaft, remove it.
4. Remove all corrosion protection from the motor shaft and contact surfaces of the motor and motor adapter.
5. Carefully remove any lubricant from the inner hole of the clamping hub (15) and, if available, the inner and outer
surface of the adapter bushing (6) for the motor shaft.
6. Unscrew the screw plug (13).
7. Turn the clamping hub so that the locking screw (11) can be turned over the bore for the screw plug (13), guide the
hexagon insert (3) through the bore and insert it into the hexagon socket of the locking screw.
8. If an adapter bushing (6) is necessary, insert the adapter bushing into the inner hole of the clamping hub (15) as far as
it will go and turn the adapter bushing so that the slot of the adapter bushing coincides with the slot of the clamping
hub (10).
