SHAFT ALIGNMENT CARDAN SHAFTS
INTRODUCTION
Cardan Shafts, or offset mounted machines, need to be aligned just as much
as an ordinary mounted machine. The cardan shaft with its ball-joints admits
an amount of offset mounting of the machines, but it does not tolerate
angular error. To be able to accomplish an alignment of an offset mounted
machine you will need to use the optional cardan fixtures. The fixtures can be
used on machines with up to 900 mm offset and is fitted for use on virtually
any kind of coupling.
See also Shaft Alignment Horizontal Machines.
MOUNTING
The cardan fixture (offset fixture) can be mounted on either unit depending
on the space available but it is always easier to mount it on the shaft which
cannot be rotated, usually the stationary machine.
Dismount the cardan shaft.
Clean the flange faces and remove any high spots such as burs from the bolt
holes.
Check the run-out of the flange face using a dial indicator. Mount the dial
indicator and rotate the shaft.
Mount the lapped steel bar with the spacers on to the flange face of the
stationary machine, either vertically or horizontally.
Mount the adjustable arm on the lapped steel bar.
Mount the revolving bracket on the adjustable arm.
Mount the other revolving bracket on to the flange of the movable machine in
any of three ways described below.
If the flange of the rotating shaft has a tapped hole in the centre,
mount the revolving bracket with a fitting tapered bolt and washer.
If the flange of the rotating shaft does not have a tapped hole in the
