  • Page 16: Installation

    This chapter contains information on how to mount a motor on a STOBER gear unit with a motor adapter. The motor adapter type of your gear unit can be found on the nameplate of the gear unit. STOBER recommends using a motor with a shaft without a feather key, since the keyway negatively affects smooth operation.

  • Page 18: Mounting The Motor On A Gear Unit With Me Adapter

    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.
  • Page 19 5 | Installation 9. If necessary, use two suitable attachment points to secure the motor with the lifting gear so that the motor shaft is pointing down vertically. 10. 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.

    This chapter describes the attachment of a motor with a solid shaft with feather key to a STOBER gear unit with an MQ (for a square motor flange) or MR (for a round motor flange) motor adapter with a curved tooth coupling. Since the assembly steps for the MQ or MR motor adapter are identical, only one motor adapter type is shown in the figures.
  • Page 22 5 | Installation 8. If necessary, use two suitable attachment points to secure the motor with the lifting gear so that the motor shaft is pointing down vertically. 9. 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.

    This chapter describes the attachment of a motor with a solid shaft without feather key to a STOBER gear unit with an MQ (for a square motor flange) or MR (for a round motor flange) motor adapter with a plug-in coupling. Since the assembly steps for the MQ or MR motor adapter are identical, only one motor adapter type is shown in the figures.
  • Page 24 5 | Installation 9. 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. 10. Carefully place the motor on the motor adapter and make sure that the claws of the motor-side clampring (9) are positioned between the claws of the gear unit-side coupling hub (7) and the teeth of the gear rim (8).
