2.4.1 Temperatures
The permissible temperature range is determined by the following:
ƒ The lubricant specifications in connection with the expected oil temperatures in
operation (see chapter 8.1 and nameplate).
ƒ The thermal class of the motor considering the motor temperature expected during
operation (see nameplate and/or Operating Instructions of the motor).
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) 100°C. If these
temperatures are exceeded, measures are necessary to reduce the
temperature, see chapter 9.
}
Danger!
Depending on the operating conditions, surfaces may be hot, provide
protection against accidental contact.
2.4.2 Ambient conditions
ƒ Gearboxes are protected against dust and spray water.
ƒ Motors according to their enclosure (see nameplate and/or Operating Instructions
for the motor).
ƒ Ambient media − especially chemically aggressive − can destroy shaft seals and
coatings (plastic). Abrasive media endanger shaft seals.
ƒ The installation site of the drive must be free of shocks and vibration.
ƒ Dirt of dust deposits impede the heat dissipation (cooling).
