Benefits of technology

The patent describes a gas turbine blade assembly and a gas turbine that can be easily disassembled and assembled while still achieving complete sealing. This makes it easier to maintain and repair the gas turbine.

Problems solved by technology

However, the above method is problematic in that a large number of members to be prepared for assembly are required, and the assembling process and the disassembling process are very complicated, whereby work efficiency is remarkably low.
The retainer according to the related art is problematic in that it requires a very complicated structure to form the cooling gas sealing and the flow path, so it is not easy to manufacture and install.

Embodiment Construction

[0055]Reference will now be made in detail to preferred embodiments of the present disclosure with reference to the accompanying drawings. Before describing, it will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0056]Throughout the specification, when a member is “on” another member, it includes not only when a member is in contact with another member, but also when there is another member between the two members. It will be further understood that the terms “comprise”, “include”, “have”, etc. when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, and / or combinations of them but do not preclude the presence or addition of one or mor...

Abstract

A gas turbine blade assembly, which is as an assembly provided with a plurality of gas turbine blades on an outer circumferential surface of a rotating disk along a circumferential direction to be spaced apart from each other at predetermined intervals, includes: a retainer insertion hole provided in a blade-fixing end, and depressed by a predetermined depth to correspond to a lower end of a retainer; a retainer coupler provided at a lower end of each of the gas turbine blades, and depressed by a predetermined depth to correspond to an upper end of the retainer; and a coupling member coupled at a location adjacent to the retainer coupler to couple the retainer and each of the gas turbine blades together.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2017-0047337, filed Apr. 12, 2017, the entire contents of which is incorporated herein by reference.BACKGROUND[0002]The present disclosure relates generally to a gas turbine blade assembly having retainer assembling structure, and a gas turbine having the same. More particularly, the present disclosure relates to a gas turbine blade assembly having a structure capable of being easily disassembled and assembled and achieving sealing, and a gas turbine having the same.[0003]Generally, a turbine is a mechanical device that obtains torque by impulsive force or reaction force using flow of compressible fluid such as steam or gas. It is called as a steam turbine when steam is used and a gas turbine when combustion gas is used.[0004]A thermodynamic cycle of the gas turbine is the Brayton Cycle, which is as follows: a compressor for sucking and boosting air from the atmosp...
