General data and operating conditions
3.3.1
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 7.1 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 8.
}
Danger!
Depending on the operating conditions, surfaces may be hot, provide
protection against accidental contact.
3.3.2
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).
3.3.3
Paint
Lenze offers paints with different resistance characteristics for drive systems. Since the
resistance may be reduced when the paint coat is damaged, defects in paint work (e.g.
through transport or assembly) must be removed professionally to reach the required
corrosion resistance.
