Measurement separation
Since the Product requires no mechanical connections (such as cantilevered dial
indicator brackets) to span over the coupling during measurement, alignment
may easily be performed over large sensor–prism separations.
Note that over very large distances the shafts and coupling may sag, and the
machines may need to be deliberately misaligned to take the catenary curve into
account, if such sag does not disappear when machines are put into operation.
Refer to the machine manufacturer’s specications.
Check for soft foot
Refer to section on soft foot on page 91.
Mount the brackets
Mount the brackets on either side of the machine coupling, and both at the same
angular position.
Please note the following in order to obtain the highest possible measurement
accuracy and to avoid damage to equipment:
Caution
Ensure that the brackets t solidly onto their mounting surfaces!
Do not use self-constructed mounting brackets, or modify the supplied
original bracket conguration (for example, do not use support posts
longer than those supplied).
Bracket mounting procedure
To t the compact bracket chains, refer to the diagrams shown on the next page
and follow the instructions carefully.
1. Choose the shortest support posts which will still allow the laser beam to pass
over the coupling ange. Insert the support posts into the bracket.
Note
In some cases, if the coupling is large enough, a coupling bolt can be removed
and the laser beam shot through the bolt hole, in order to avoid protruding
radially beyond the coupling’s outer diameter (OD).
