Specialised shrink fitting machine for the assembly of reactor rings. The ring is fitted inside an aircraft casing using a shrink fitting process. The shrink fitting assembly process used in this application involves expanding the receiving part (the casing) by the application of heat to produce a robust assembly.

Requirement / A safe installation using a shrink-fitting process.

In addition to very accurate positioning of the components, the customer also required that the installation be extremely safe. As the abradable material is shrink fitted in a very high temperature environment, the machine needed to provide protection for the operator and other persons from the heat generated at the work station.

Solution / A specialised shrink fitting machine and tool.

A custom slide shrink fitting machine with component loading and unloading. When the slide is closed the parts are impossible to touch to prevent risks to the operator; the shrink fitting operation can be performed in complete safety. Heat is provided by heating collars designed especially for this application. Shrink fitting operations are controlled using a tactile interface and the assembly machine is easy to use on a day-to-day basis.

The machine’s performance levels /

• Shrink fitting temperature 200°C
• Ø of components up to 1120 mm.
