The customer bears the sole responsibility for all machining processes performed
subsequently on unbored or pilot bored as well as finish machined coupling components
and spare parts. KTR does not assume any warranty claims resulting from insufficient
remachining.
KTR supplies unbored or pilot bored coupling components and spare parts only upon
explicit request of the customer. These parts are additionally marked with the symbol
.
Reference to unbored resp. pilot bored coupling components with explosion protection
marking:
Basically the company KTR supplies couplings resp. coupling hubs with explosion protection
marking as an unbored or pilot bored type only on explicit request of the customer. The prerequisite
is a declaration of exemption submitted by the customer assuming any responsibility and liability for
remachining performed properly.
!
In case if a dimensional drawing was prepared for the coupling, the dimensions specified
have to be primarily observed.
The operator of the machine should be provided with the dimensional drawing.
We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.
Please pay attention to the ignition risk in potentially explosive atmospheres!
STOP
Touching the heated components causes burns.
Please wear safety gloves.
!
With the assembly please make sure that the distance dimension E (see table 1, 3, 5 and 7)
is observed to allow for axial clearance of the sleeve while being in operation.
Disregarding this advice may cause damage to the coupling.
If used in potentially explosive atmospheres the setscrews to fasten the hubs as well as all
screw connections must be secured against working loose additionally, e. g. conglutinating
with Loctite (average strength).
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
