The coupling has to be regularly inspected for leakages/grease capacity, unregulated heating and modifications of
the running noise. The inspection has to be performed during the general maintenance intervals, at least every
quarter of a year.
Moreover, the correct fit of the protective device for rotating parts has to be inspected.
The following items of inspection are the main components of maintenance work:
Grease:
grease capacity, replacement of grease (see chapter 5.3 and 7.2)
Sealing elements:
leakages, replacing of sealing elements (see chapter 7.3)
Shaft displacements:
re-aligning the coupling (see chapter 4.6)
Spline:
wear, inspection of circumferential backlash (see chapter 7.5 and 7.4)
Maintenance intervals in potentially explosive atmospheres:
If the coupling is used in potentially explosive atmospheres, considerably shorter
maintenance intervals have to be observed!
The coupling has to be inspected after approx. 200 operating hours or every month at the
maximum.
!
In order to ensure a long service life of the coupling and avoid damages on the coupling, the
quantities of grease specified for the different coupling sides and the intervals of
replacement of grease absolutely have to be observed!
Grease has to be collected completely and disposed of according to the regulations that
apply.
STOP
Please observe the manufacturer’s instructions on handling greases.
The replacement of grease depends on various operating conditions such as load, ambient temperature, speed,
shaft displacements and operating period. Anyway, the replacement of grease is recommended for an operation
up to 70 °C after about 8,000 hours of operation, a maximum of 2 years and for an operation exceeding 70 °C
after about 3,000 hours of operation, a maximum of 1 year.
Please note that when you replace the grease the remaining quantities in the coupling should be kept as small as
possible.
Please have the manufacturer confirm the compatibility of the new lubricant with remainders of the former
lubricant.
If the coupling is used in potentially explosive atmospheres, considerably shorter
maintenance intervals have to be observed!
The coupling has to be inspected after approx. 200 operating hours or every month at the
maximum.
Lubricants of various types and manufacturers must not be mixed!
