Abstract (en)
[origin: CA2742868A1] The invention relates to a device (1) and to a method associated with an assembly mechanism for a rotor system of an axial turbo engine having a central tension anchor, as is particularly known from engine technology. To this end, the invention provides a tensioning tool that pre-tensions the tension anchor prior to and during the insertion of the same in the rotor assembly. After inserting the pre-tensioned tension anchor in the rotor assembly, the tension anchor is relaxed such that the same exerts a compressive force on the rotor assembly. According to a preferred embodiment, the rotor assembly is also pre-tensioned (compressed) and relaxed after assembling the tension anchor, so that a desired nominal pre-tension SigmaNenn can be particularly easily achieved. The use of a shaft lock nut is no longer necessary for the device according to the invention, thus avoiding the difficulties associated with the use of the same, such as complexity and safety problems. The invention further relates to a method for assembling a tension anchor (2) for a rotor system (6) using the assembly mechanism according to the invention.
