Installation and Adjustment Guidelines for MINIRAIL and MINISCALE PLUS
16.2 Installation Methods
Different criteria must be taken into consideration when choosing an appropriate
installation method and defining the number and arrangement of the lateral
reference surfaces. These are:
16.2.1 Load
16.2.2 Accuracy
16.2.3 Installation time and engineering expense
16.2.4 Installation location and specifics
16.2.1 Load
Forces in the direction of tension/compression do not have any influence on the
lateral reference surfaces. If side loads emerge which exceed the permitted lateral
force, references and lateral clamping must be specified. Number and orientation
depend on the forces that occur.
The reference surfaces should be arrangedbased on the direction of force of the
main load. Lateral references should also be provided when vibration and impacts
occur. They also increase the rigidity of the system.
16.2.2 Accuracy
Lateral reference surfaces are recommended if a high level of guideway accuracy is
required. The references make installation easier and reduce the complexity
involved in ensuring accuracy. The guideway accuracy is determined by the
straightness of the reference surfaces and by the guide rail compression process
and/or by the accuracy of the lateral clamping.
16.2.3 Installation Time and Engineering Expense
Reference surfaces make installation easier and reduce the complexity involved in
aligning the guide rails.
With careful manual alignment of the guideway, it is possible to dispense with the
need for lateral reference surfaces. When deciding on a method, the complexity of
the installation should be carefullyconsidered and compared with the design and
technical manufacturing complexity.
16.2.4 Installation Location and Specifics
Reference surfaces and lateral clamping require additional installation space and
access to the installation areas. It is therefore important to check whether the
provided references andadjustments are compatible with the installationareain
the machine.
Shownbelow are some typical installation methods which differ in terms of the
number and orientation of the reference surfaces, the transferable lateral forces
and the complexity of installation, and are intended to serve as a design aid.
