Temperatures
The permissible temperature range is determined by the following:
¯
The lubricant specifications in connection with the expected oil temperatures in
operation (see chapter 7.2 and nameplate).
¯
The thermal class of the motor considering the motor temperature expected
during operation (see nameplate and/or operating instructions of the motor).
¯
Protect geared motors against direct solar radiation. Avoid heat concentration
beneath covers.
The operating temperature is determined by the power loss, the ambient temperature
and the cooling system!
Stop!
With mineral oil, the upper temperature limit for continuous operation is
80°C, with synthetic oil and shaft sealing rings made of FP (Viton) it is
100°C. If these temperatures are exceeded, measures are necessary to
reduce the temperature, (
Danger!
Depending on the operating conditions, surfaces may be hot, provide
protection against accidental contact.
Ambient media
¯
Gearboxes are protected against dust and spray water.
¯
Motors according to their enclosure (see nameplate and/or operating instructions
for the motor).
¯
Ambient media − especially chemically aggressive − can destroy shaft seals and
coatings (plastic). Abrasive media endanger shaft seals.
¯
The installation site of the drive must be free of shocks and vibration.
¯
Protect geared motors against direct solar radiation. Avoid heat concentration
beneath covers.
¯
Dirt of dust deposits impede the heat dissipation (cooling).
Transport
Before transport
¯
check that all component parts are safely mounted;
¯
check that all component parts with a loose fastening are secured or removed;
¯
tighten all transport aids (eye bolts or support plates).
Use an appropriate means of transport and lifting equipment! (
