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. |
