Abstract

The invention discloses a disassembling device and method for a power turbine disc of a lightweight gas turbine. Connecting holes are formed in the left end and the right end of the turbine disc symmetrically. Shaft holes are symmetrically formed in the middle of the turbine disc up and down. The disassembling device for the power turbine disc of the lightweight gas turbine is composed of an ejector rod, an upper pressing board, a positioning pin assembly, a left block, a core block, a right block and a lower pressing board, wherein through hole structures are formed in the positions, corresponding to the connecting holes, of the upper pressing board; the upper pressing board is in threaded connection with the upper end of the turbine disc through the ejector rod, the connecting holes and the through hole structures. According to the disassembling method for the power turbine disc of the lightweight gas turbine, the major stress concentration point acts on the pressing boards, possible damage to the surface and the internal structure of the turbine disc is reduced, and a turbine disc assembly is disassembled with no damage on the condition that technical demands are met; the method is simple, can be applied flexibly and is also suitable for other types of disassembling disc assemblies on the operating scenes with simple conditions.

Description

Technical field [0001] The invention relates to the technical field of structural design and application of a turbine disc decomposition device, and in particular provides a light-weight gas turbine power turbine disc decomposition device and method. Background technique [0002] After the power turbine reaches the overhaul life, the decomposition inspection will be carried out. Due to the different conditions encountered during operation or storage, the power turbine disc will be rusted and adhered during the disassembly process, and decomposition will be difficult. [0003] People are eager to obtain a light gas turbine power turbine disc decomposition device and method with excellent technical effects. Summary of the invention [0004] The purpose of the present invention is to provide a light-weight gas turbine power turbine disc decomposition device and method with excellent technical effects. Under the premise of not damaging the turbine disc, use the decomposition device to ...
