3.6 Technical Data
The erection and installation should
be made only when the roller or chain
conveyor is not in operation.
4.1 Mechanical installation
Attention:
A supporting framework with
sufficient resistance
must be installed
for mounting 4 threaded spindles M 20
(holes acc. to dimensional drawing) at
the roller or chain conveyor to be
lubricated.
Attention:
Protect against access by
unauthorized
persons.
Danger
of
crushing while the COBRA is in
operation.
Determination of the installation height:
The COBRA 501 lubrication head center line must be
parallel to and at the same height as the center line of the
rollers to be lubricated during the whole carriage runway.
Compensate any fluctuation in height by setting the M 20
threaded spindles at the fixing device.
The maximum fluctuation in height of the lubrication nipple
is ± 10 mm from the center of the lubrication head.
Note
:
The fluctuation in height of the lubrication nipple results from
the
fluctuation in height of the roller + eccentricity of the
lubrication nipple on the eccentricity of the roller
.
If the fluctuation in height of the lubrication nipple is greater,
the chain must be guided accordingly in the COBRA engaging
area.
chain speed
chain pitch
(
Chain pitch means the distance between the rollers to be
lubricated)
