Installing the gear unit
Use plastic inserts (2 – 3 mm thick) if there is a risk of electrochemical corrosion between
the gear unit and the driven machine (connection between different metals such as cast
iron and high-grade steel)! Also fit the bolts with plastic washers! Ground the housing
additionally – use the grounding bolts on the motor.
Installation in
damp areas or in
the open
Gear units are supplied in corrosion-resistant versions for use in damp areas or in the
open air. Any damage to the paintwork (e.g. on the breather valve) must be repaired.
Gear unit venting
All gear units are delivered by SEW ready for the mounting position with the breather
valve and transport fixture fitted.
Exception:
Gear units for pivoting or inclined mounting positions and gear head units are delivered
with a screw plug on the vent hole provided. Prior to startup, the customer must replace
the highest screw plug by the supplied breather valve on each individual gear unit!
•
With geared motors for long-term storage, pivoting or inclined mounting positions,
the supplied breather valve is located in the motor terminal box.
•
With gear head units that have to be vented on the input side, the breather valve is
supplied in a plastic bag.
•
No breather valve will be supplied for gear units in enclosed design.
Activating the
breather valve
Usually the breather valve is activated in the plant. Should this not be the case,
the transport fixture must be removed from the breather valve prior to the startup
of the gear unit!
Painting the gear
unit
Cover breather valve and oil seals with protective tape prior to painting or partly re-
painting the drive. Remove adhesive strips when the paint job is finished.
