In order to
guarantee the properties of the cardan shaft as
described in the information brochure they must
not be altered from its as-delivered state.
Whenever people or material might be
endangered by rotating cardan shafts, the user
must provide for the corresponding safety
devices. |
 |
Suitable safety
devices (e.g. catch bows, solid safety guards)
must be provided to prevent the parts of the
shaft from being thrown around.
Danger to life! |
|
|
Cardan shafts are
elastic and flexural bodies. Their flexural
vibration and their critical bending speed must
be calculated. The maximum permissible operating
speed must be sufficiently below the critical
bending speed of the first order. |
|
|
For the smooth
running and safety of the shaft the n x β value
(speed x deflection angle) of the relevant shaft
size must not be exceeded.
Please contact us. |
|
|
The faces and the
centering diameter of the shaft flanges and
companion flangesmust be free of dust, grease or
paint to guarantee a safe connection. |
|
|
Be careful when
handling the cardan shaft. Freely moving flange
yokes may cause INJURIES! |
|
|
Check position of
the yokes (1) of the shaft. Observe the arrow
markings (2). They must be in alignment. The
splines are fitted and must not be exchanged or
distorted.
 |
|
|
Before
installation remove the transport retainer
device, if present. In case of doubt please
contact the supplier. |
|
|
Check the radial
and radial runout as well as the spigot fit of
the mounted flanges and the connected units (see
Flange boltings). |
|
|
Do not turn the
joints of the cardan shafts with assembly levers
because this may damage the grease nipples or
relief values. |
|
|
Use nuts and
bolts of the prescribed quality (strength) (see
Flange boltings). |
|
|
Only use nuts and
bolts in accordance with the supplier's
specification. |
|
|
The bolts should
be evenly tightened crosswise with a torque
wrench (see
Flange boltings). |
|
|
When using cardan
shafts without length compensation, one of
the connecting units must be flexible in
order to be fitted over the flange pilot.
Variations in lenght which may be caused by
temperature changes must be allowed for by a
suitable connecting bearing. |
|
|
If cardan shafts
with length compensation are used, the
companion flanges must be firmly fitted on
the shafts of the connected units. |
|
|
Cardan shafts
that have been stored for more than 6 month must
be relubricated before use (see
Maintenance). |
|
|
For
spray-painting the cardan shaft, make sure that
the sliding range of the seal (length
compensation La) is covered.
 |
|
|
Protect rilsan
coated splines (sleeve muff or sleeve yoke)
against
- heat
- solvents
- mechanical damage
|
|
|
When cleaning
cardan shafts, do not use aggressive chemical
detergents or pressurized water or steam jets
because the seals may be damaged and dirt or
water may penetrate. |
|
|
Cardan shafts can
be used in a temperature range between -25°C
(-13°F) and +80°C (+176°F), up to +120°C
(+248°F) but only for limited periods and not on
a frequent basis. Please contact us if the
operating temperature deviates from these values.
