In order to
guarantee the properties of the cardan shaft as
described in the information brochure they must
not be altered.
Whenever people or material might be
endangered by rotating cardan shafts, the user
must take for the corresponding safety measures. |
 |
Safety relevant
components of the vehicle and brake lines,
electric lines, hydraulic and fuel lines must be
arranged in such a way that they cannot be
damaged by a defective cardan shaft.
Danger of breakdown of important units!
Danger of fire! |
|
|
Suitable safety
devices (e.g. catch bows, solid safety guards)
must be provided to prevent the parts of the
shaft from being thrown around and to prevent
damage to other parts of the unit if the cardan
shaft should become defective. In the view of
DANA such safety devices may be dispensed with
provided that a comparable form of security is
guaranteed during operation of the vehicle
through suitable engineering measures taken by
the vehicle manufacturer.
Danger to life! |
|
|
The fronts of the
DIN and SAE shaft flanges and companion flanges
must be free of dust, grease or paint in order to
guarantee a safe connection.
The anti-corrosive on cross-Serration flange
teeth need not be removed. Other particles must
be removed. |
|
|
Be careful when
handling the cardan shaft.
Freely moving yokes may cause injuries! |
|
|
Check position of
the yokes (1) of the shaft. Observe the arrow
markings (2). (They must be in alignment.) The
spline components are matched for a smooth
fitting and must not be interchanged or remounted
at a different angle.
 |
|
|
Before
installation remove any transport retainer device.
If in doubt please contact the supplier. |
|
|
Check the side
and radial runout as well as the fit of the
mounted flanges and the connected units (see companion flanges for
cardan shafts). |
|
|
Do not turn the
joints of the cardan shafts with assembly levers
because this may damage the grease nipples or
seal arrangement on the bearings. |
|
|
When painting
ensure that the sliding range of the seal (length
compensation La) is protected.
 |
|
|
Protect rilsan
coated splines (sleeve muff or sleeve yoke)
against
- heat
- solvents
- mechanical damage
|
|
|
When cleaning
cardan shafts, do not use aggressive chemical
agents or pressurized water or steam jets because
the seals may be damaged and dirt or water may
penetrate. |
|
|
If cardan shafts
are subjected to higher temperatures, e.g. due to
noise-reduction measures or retarders, suitable
means should be provided to ensure that the limit
values are not exceeded. |
Installation
of drive lines
Midship shafts are supplied complete with centre
bearings ready for installation.
The centre bearing and the companion flange are
fixed on the midship shaft by means of bolts
which are secured against working loose.
For reasons of safety these bolts must never be
loosened or retightened on new shafts. They may
only be loosened for repair work, but they must
be properly secured again after the repair.
 Midship shaft
without length compensation
with centre bearing
To avoid cases of non-uniformity, drive lines
consisting of the midship shaft with the centre
bearing and the normal cardan shaft must be
installed in accordance with the yoke position of
the joints prescribed by vehicle manufacturer.
|
 |
When installed,
the centre bearing must be vertical in all
directions with regard to the horizontal axis of
the midship shaft and be in a central position.
Suitable mounting supports must be provided on
the frame side. A continuous stable support must
be provided between the centre bearing bracket
and the mounting support (see illustration).
 |
|
|
To guarantee a
safe bolting of the centre bearing bracket of the
midship shaft to the frame of the vehicle, always
use the bolting prescribed by the manufacturer of
the vehicle. |
|
|
These
bolts must be strictly secured against working
loose in accordance with the instructions of the
vehicle manufacturer. |
|
|
The centre
bearing of the midship shaft must be installed
without force.
Therefore the centre bearing must not be bolted
to the frame of the vehicle until the drive and
the driven sides of the drive line have been
bolted down. |
|
|
To avoid damage
to the joint bearings it is important to protect
them against excessive sagging or deflection
during the entire installation procedure.
 |
Moreover, the general instructions in our cardan
shaft catalogues for vehicles and industrial
application are to be observed for the
dimensioning, arrangement and installation of
drive lines and midship shafts. |
Installation of centred double cardan
shafts
When installing the cardan shaft, care should be
taken not to damage the location bearing by
excessively deflecting the joint. This can be
achieved by using a mounting rope. |
