5.2.4 Mounting the motor on a gear unit with MB adapter
The assembly of a motor on a gear unit with an MB motor adapter with brake is described in a separate document (see
Supporting documents [ } 5] ).
5.2.5 Mounting the motor on a gear unit with MQ adapter
This chapter describes the attachment of a motor to a STOBER KL gear unit with an MQ motor adapter.
Prerequisites
§ Dimensional tolerances of the motor correspond to the requirements in the chapter Tolerances for the add-on motor
[ } 23]
§ The permitted tilting torque on the gear unit input is not exceeded (see Permitted tilting torques at the gear unit input
[ } 23] )
§ 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 [ } 22] )
§ The information in the chapter Cleaning agent and solvent [ } 22] is observed
Procedure
1. Position the gear unit with the motor adapter facing upwards 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 clamping sleeve (6) for the motor shaft.
6. Unscrew the threaded sealing plug (13).
7. Grease the coupling element (16) and position it between the claws of the coupling hub (15).
8. Position the clamping hub (14) on the coupling hub and make sure that the claws of the clamping hub are positioned
between the teeth of the coupling element and the claws of the coupling hub.
9. Turn the clamping hub so that the locking screw (11) can be turned over the bore for the threaded sealing plug (13),
guide the hexagon insert (3) through the bore and insert it into the hexagon socket of the locking screw.
10. If a clamping sleeve (6) is necessary, insert the clamping sleeve into the inner hole of the clamping hub (15) as far as it
will go and turn the clamping sleeve so that the slot of the clamping sleeve coincides with the slot of the clamping hub
(10).
11. If necessary, use two suitable attachment points to secure the motor with the lifting gear so that the motor shaft is
pointing down vertically.
12. Turn the motor in an axial position to the gear unit so that the nameplates are on the same side, if possible, and can
also be read after installation in the machine.
13. If the motor shaft has a keyway, position the motor shaft so that the keyway faces the slot of the clamping hub (10).
14. Carefully place the motor on the motor adapter (4) and make sure that the motor shaft is inserted (7) in the clamping
hub (15) so that it is centered and not at an angle.
