Shaft sealing ring
12.4
The FKM radial shaft sealing ring serves to seal against splash wa-
ter and to protect the motor shaft against the ingress of dust or dirt.
This increases the protection class of the shaft feed through to IP65.
The radial shaft-sealing ring can be replaced at any time. Please
note, however, that the exchange may lead to a reduction in the
nominal values.
12.5
Gear unit
Axial load due to thermal expansion of the motor shaft
To avoid displacement of the motor shaft at high temperatures, use
couplings as length compensation.
Directly mounted bevel gears or helical gear wheels can exceed
the axial load of the floating bearing on the shaft end A.
A gear unit serves to transmit a moment of force or a torque and is
used on the motor as an output element. Information on flange sizes
for combinations of motor and gear unit can be found in the chapter:
Type key.
