METHOD FOR ASSEMBLING AND DISASSEMBLING A ROTOR HAVING A NUMBER OF ROTOR COMPONENTS OF AN AXIAL FLOW TURBOMACHINE AND SUCH A ROTOR

摘要

The invention relates to a rotor (10) for an axial flow turbomachine comprising a number of a plurality of disc shaped (12) or drum shaped (16) rotor components and at least one pin shaped tie rod (20) extending through the rotor components (14) wherein a counter bearing (26, 28) is screwed onto each of the projecting ends of said tie rod for axially bracing the rotor components (14) arranged therebetween. The aim of the invention is to provide a rotor (10) by which shorter service intervals can be achieved. In order to achieve said aim a connecting means (34) is screwed onto the tie rod (20) between both counter bearings (26, 28) wherein after the release of one of the two counter bearings (28) the rotor components (12, 14) arranged between the connecting means (34) and the other of the two counter bearings (26) are braced with each other by means of said connecting means (34).
