Configuration Manual, 09/2018, A5E45099423B AA
51
The motor shafts are sealed according to the degree of protection that is ordered.
Table 3- 10 Sealing of the motor shaft
Labyrinth seal
It is not permissible that there is
any moisture in the area around
the shaft and the flange.
Note:
For IP 64 degree of protection it is
not permissible for liquid to collect
in the flange.
Radial shaft sealing ring without annular
spring
Sealing of the shaft exit against
splashwater or coolant. It is permissible
that the radial shaft sealing ring runs
dry. Lifetime approx. 25000 hours
(nominal value).
With degree of protection IP65, it is not
permissible for liquid to collect in the
flange.
Radial shaft sealing ring
For gearbox mounting (for gearboxes that
are not sealed) to seal against oil.
The sealing lip must be adequately cooled
and lubricated by the gearbox oil in order to
guarantee reliable function.
Lifetime approx. 10000 hours (nominal
value).
If a radial shaft sealing ring runs dry, then
this has a significant negative impact on the
functionality and the lifetime.
Sealed through the motor flange
You can additionally seal motors at the flange
1 flat contact surface for the O ring
The motor is sealed using an O ring on a flat machined contact surface of the centering edge
at the DE flange. The whole circumference is sealed.
The flange surface of the motor is not used to establish the seal.
