Collect data and align
Proceed as in the horizontal machine alignment. Pay attention to the following differences:
-
The minimal shaft rotation angle must not be smaller than 75°
-
Corrective values for the parallel misalignment are irrelevant when it comes to cardan shafts and
will not be displayed
-
Standard tolerances cannot be used for cardan shafts. Please ignore them.
-
Only corrective values for one machine base are needed, because parallel misalignment is not
corrected with cardan shafts.

Alignment of machine trains
7.5.1
Short explanation
A machine train consists of three or more units with rotating shafts, which are connected with couplings,
as for example driving unit
– gear – driven unit. With a common alignment measurement, an alignment
measurement for every single machine would be necessary. The PCE-TU 3 system performs all
necessary measurements automatically and offers the possibility to define the stationary or reference
machine. To use this function, you should be familiar to
chapter 7.1 (“Horizontal machine alignment”)
.
7.5.2
Execution of a machine train alignment
To start the program, select “machine train” and press
. The main screen of the program will appear.
What should be noted in this window
Shortcuts in this window
Similar to the horizontal alignment, a Soft
Foot Measurement should be carried out
before. If needed, corrections should be
made. Do not forget to enter the dimensions
in the menu for the horizontal machine
alignment.
Create a new train (initially 3
units in the train)
All needed dimensions should be entered
correctly.
The Sensor M must always be placed right to
the coupling on the machine; also it is
actually a stationary one.
Functions in this window
Dimensions of the machines and
the selected coupling need to be
entered first.
