    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 21 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 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 26 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).

  • Page 36: Commissioning

    The maximum surface temperature occurs in approx. 3 hours, depending on the utilization of the drive, and must not exceed the maximum value of 90 °C in the event of a maximum surrounding temperature. Immediately shutdown the drive if the maximum value is exceeded and contact STOBER Service.

  • Page 37: Servicing

    7 | Servicing Servicing Cleaning If the surface of the drive is dirty, heat dissipation through the ambient air is no longer sufficient. As a result, impermissibly high operating temperatures that reduce the lubricating effect of the lubricant and accelerate its aging could occur. This has a negative effect on the service life of the drive.

  • Page 38: Changing The Oil

    7.2.1 Changing the oil You can find information on the oil change for K5 – K10 gear units in this chapter. K1 – K4 gear units are lubricated for their entire service life and do not require an oil change.
