Maintenance

Motor reductor
De-energise the motor and make sure it cannot be switched back on without your knowledge.
Wait until it has cooled down – DANGER
FOR BURNING!
Regularly check if the motor produces more noise than normal, or if it generates more heat than normal.
If that is the case, find out what the cause is and solve the problem(s) as soon as possible to prevent
(further) damage.
In the table below, general inspection and maintenance intervals are shown as an indication of the
inspection and maintenance that is needed.
REDUCTOR
Frequency
What to do?
•
Every 3000 machine hours, at least every 6 months.
•
Check oil and oil level.
•
Check the seals visually for leakage.
•
For gear units with a torque arm: Check the rubber buffer
and change it, if necessary.
•
Depending on the operating conditions (see chart
below), every 3 years at the latest.
•
According to oil temperature.
•
Change oil.
•
Replace anti-friction bearing grease (recommendation).
•
Replace oil seal (do not install it in the same track).
•
Depending on the operating conditions (see chart
below), every 5 years at the latest.
•
According to oil temperature.
•
Change synthetic oil.
•
Replace anti-friction bearing grease (recommendation).
•
Replace oil seal (do not install it in the same track).
•
Some gear units (like SEW R07, R17, R27, F27 and Spiroplan®) have lubrication for life and are therefore maintenance-
free.
•
Varying (depending on external factors).
•
Touch up or renew the surface/anticorrosion coating.
MOTOR
Frequency
What to do?
•
Every 10.000 hours of operation.
Inspect the motor:
•
Check ball bearings and change if necessary.
•
Change the oil seal.
•
Clean the cooling air passages.
