7 Assembly
7.1 Pay attention before the assembly
•
Danger of injuries!
•
Disconnect the drive before carrying out any work on the coupling!
•
Secure the drive against unintentional re-start and rotation!
-
Incorrectly tightened bolts can cause serious personal injuries and
property damages!
•
In compliance with accident prevention regulations, you are
obliged to protect all freely rotating parts by means of permanently
installed guards/ covers against unintentional contact and falling
down objects.
•
To avoid sparks, the covers for couplings used in explosive
atmospheres should be made of stainless steel!
•
As a minimum, the covers have to fulfil the requirements of protec-
tion type IP2X.
•
The covers have to be designed to prevent dust from depos
iting on
the coupling.
•
The cover must not contact the coupling or impair the proper
function of the coupling.
•
Make sure that the speeds, torques and ambient temperatures as stated in chapter 6
‘Technical Data’ are not exceeded.
•
The maximum permissible bore diameters must not be exceeded.
•
Check whether the shaft-hub connections safely transmit the occurring operating torques.
•
The standard tolerance of
RINGFEDER
®
TNM
for finish bores is fit H7.
•
Standard keyways comply with DIN 6885, sheet 1.
•
Check the dimensions and tolerances of shafts, hub bores, keys and keyways.
•
Set screws as required.
7.2 Finished borehole
For the completion of the finished borehole in a coupling hub, pay attention to following
procedure:
•
Clean the coupling hub of preservatives.
•
Tighten the coupling hub to the surfaces marked with
and carefully align the coupling
hub.
•
The indicated values in table 1 for ød
1max
are valid for a parallel key connection according
to DIN 6885/1 and must not be exceeded.
•
Choose the borehole fit so that during the union with the shaft tolerance a wringing fit
and/or an interference fit as for example at H7/m6 is carried out.
•
Provide a setscrew for axial securing on the hub back above the parallel key slot.
In the case of other shaft hub connections, consultation with
RINGFEDER POWER
TRANSMISSION
is necessary.
