Components between the motor and the gear unit, e.g. turbo couplings or brakes are pre-adjusted
prior to delivery: The alignment and adjustment of these components must be checked and corrected
according to the corresponding manufacturer's documentation prior to commissioning the gear unit.
Incorrect alignment will result in premature failure of the attached components and the gear unit.
Pay attention to all the notes on installation and assembly contained in the present manual and also
the separate operating and assembly instructions of all installed components (e.g. couplings or
brakes).
Additional notes on the installation of the motor swing base
• Push-on gear unit via hollow shaft (option A, EA), see section 3.7 "Gear unit with hollow shaft
(Option: A, EA)"
• Solid shaft with flange coupling, see section 3.6 "Fitting hubs on the gear shafts"
• Hollow shaft with fastening element (option B), see section 3.7.1 "Hollow shaft with fastening
element (Option: B)"
• Hollow shaft with shrink disc (option S), see section 3.7.2 "Hollow shaft with shrink disc element
(option: S)"
NORD recommends a g6 fit for the bolt supporting the elastic element.
To facilitate installation and to protect against corrosion, a suitable lubricant may be applied to the
inner diameter of the elastic element.
The elastic element is made of an elastomer that can be used up to a temperature of +40°C.
Depending on the component, the elastic element is capable of compensating for a small assembly-
related offset. For specifications, refer to the manufacturer's documentation.
3.11 Motor mount (Option: MT)
Gear units with motor mounts and belt drives are pre-adjusted prior to delivery. Check the alignment of
the motor and the belt tension prior to commissioning the gear unit.
3.12 Belt drives
WARNING
Risk of belt damage from incorrect installation
A damaged belt may break during operation. This can result in severe injuries.
• Before installation the axle spacing must be reduced so that the belt can be inserted into the
groves without the use of force.
• Forcible mounting belts by means of tyre levers, screwdrivers etc. is completely impermissible, as
this often causes invisible damage to the stretch-resistant tension cord or the surrounding fabric.
Information
In the standard version, V-belt drives cannot be combined with a mounting flange or fan, as these
options would conflict with each other.
