18.4.9 Load of the shaft sealing ring is xxx %, regarding the speed
18.4.10 Wear of the gearbox >100 %
18.4.11 Using synthetic oil for gearboxes of the winding application
Note!
The load of the shaft sealing ring is xxx %, regarding the speed.
This may cause reduced service intervals.
Cause Effects Possible remedies
The input speed for the shaft sealing
ring on the motor side is too high.
The service life of the shaft sealing
ring on the motor side is considerably
reduced.
• Select a different gearbox.
• Select motor with lower input
speed.
 Thermal utilisation ( 339)
Warning!
DSD has calculated a wear of xxx % for the gearbox.
Thus the limit value of 100 % is exceeded.
Contact your Lenze sales partner.
Cause Effects Possible remedies
DSD has detected in accordance with
the defined operating conditions
that the gearbox will not safely with-
stand five years of operation.
The expected service life will be pos-
sible not attained at cyclic operation.
• Can only be scrutinised by Lenze.
• Contact Lenze sales partner and
arrange for the check to be made.
Note!
Use synthetic oil (fuel-efficient engine oil) for the gearbox of this winding application.
That way, friction is reduced.
Cause Effects Possible remedies
The viscosity and temperature stabil-
ity of mineral oils are not suitable for
repeatable, high torque setting rang-
es.
Repeatable minimum tensile forces
cannot be reached.
Use synthetic oil.
