It is aimed at points. [Structure] A concave portion 4 is formed at the tip of a moving blade 1 provided with a large number of cooling holes 3 and a curing tape 6 having the same shape as the moving blade tip shape is fitted into the concave portion 4. By affixing with (1), it is possible to prevent the polishing dust generated when the slanted surface portion 4 of the rotor blade outer diameter portion is polished by the grinder from entering the cooling hole 3.
Description
【０００１】[0001]
本考案はガスタービンロータに装着される動翼の先端研磨時に使用される養生 用テープに関する。 The present invention relates to a curing tape used for polishing the tip of a moving blade mounted on a gas turbine rotor.
【０００２】[0002]
ガスタービン動翼は、その冷却効果を上げるため、翼に多数の冷却穴が穿設さ れている。 Gas turbine blades are provided with a large number of cooling holes to improve their cooling effect.
【０００３】 一方、その回転する動翼の先端は、動翼外周に配置した静翼との間の運転中の クリアランスを守るため、グラインダーにより外径加工が施される。On the other hand, the tip of the rotating moving blade is subjected to an outer diameter processing by a grinder in order to protect a clearance during operation with a stationary blade arranged on the outer periphery of the moving blade.
【０００４】 従来このようなグラインダーによるチップ加工を動翼先端部に対して行なう際 は、研磨カスが動翼に穿設した冷却穴に入らないようにテープでシールして養生 を行なっていた。[0004] Conventionally, when chips are processed by such a grinder on the blade tip, curing is performed by sealing with a tape so as to prevent polishing debris from entering cooling holes formed in the blade.
【０００５】[0005]
ところが前述のような従来技術では、翼先端の冷却穴は、先端部に設けた凹部 に穿設されており、また、その形状は曲線形状を構成しているため、研磨カスの 養生のために、翼先端にテープを貼ろうとしてもテープがはみ出してしまい、極 めて貼りにくい不具合があった。 However, in the conventional technique as described above, the cooling hole at the tip of the blade is bored in the concave portion provided at the tip, and the shape of the cooling hole constitutes a curved shape, so that it is used for curing the polishing residue. However, even if I tried to attach the tape to the tip of the wing, the tape protruded, and there was a problem that it was extremely difficult to attach it.
【０００６】 本考案は上記不具合点を解消し冷却穴への研磨カスの混入を防止できる新たな チップ研磨用養生テープを提供することを目的としている。An object of the present invention is to provide a new chip-polishing curing tape capable of solving the above-mentioned problems and preventing the inclusion of polishing dust in the cooling holes.
【０００７】[0007]
上記目的を達成するための構成として本考案のチップ研磨用養生テープは、多 数の冷却穴を翼先端部に設けた凹部の外周に間隔を置いて穿設したガスタービン 動翼における前記翼先端凹部に嵌り込み貼着するためのテープを、動翼先端形状 と同形状に構成したことを特徴としている。 As a configuration for achieving the above object, a curing tape for chip polishing according to the present invention is a blade for a gas turbine blade in which a plurality of cooling holes are provided at intervals on the outer periphery of a recess provided in the blade tip. It is characterized in that the tape for fitting into the recess and adhering it is formed in the same shape as the blade tip shape.
【０００８】[0008]
上記のように構成した本考案のチップ研磨用養生テープによれば、テープが動 翼先端の凹部に嵌り込むよう動翼形状と同形状にあらかじめ形成されているので 、容易に該テープを動翼先端凹部に貼着でき、グラインダーにより動翼先端部を チップ加工して外径修正を行なう際に、同テープを貼るだけで冷却穴を完全に塞 ぐことが可能となり、加工時発生する研磨カスが冷却穴に混入することを防ぐ。 According to the tip-polishing curing tape of the present invention configured as described above, the tape is preformed in the same shape as the moving blade so as to fit into the concave portion of the moving blade tip. It can be attached to the recess of the tip, and when the tip of the blade is machined with a grinder to adjust the outer diameter, it is possible to completely block the cooling hole just by pasting the same tape, and the polishing residue generated during processing Prevent it from entering the cooling holes.

以下図面により本考案の１実施例について説明する。 図１は本考案の１実施例を適用するガスタービンロータの全体側面図、図２及 び図３は同ロータにおける動翼先端部に本考案テープを取付ける状態の説明図で ある。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall side view of a gas turbine rotor to which an embodiment of the present invention is applied, and FIGS. 2 and 3 are explanatory views showing a state in which the tape of the present invention is attached to the rotor blade tip portion of the rotor.
【００１０】 これらの図において１は動翼で、ガスタービンロータ１０に複数枚装着される 。２は各動翼のチップ研磨する外径を示す。チップ研磨は動翼外径部分２をグラ インダーにより研磨するものである。In these drawings, reference numeral 1 denotes a moving blade, and a plurality of blades are mounted on the gas turbine rotor 10. Reference numeral 2 indicates the outer diameter of each blade for chip polishing. The tip polishing is to polish the outer diameter portion 2 of the moving blade with a grinder.
【００１１】 動翼１は冷却用の穴３を多数間隔を置いて穿設されており、また翼先端には凹 部４が先端部全面に亘り形成されている。The moving blade 1 is provided with a number of cooling holes 3 at intervals, and a concave portion 4 is formed at the blade tip over the entire tip portion.
【００１２】 ５はグラインダーによりチップ研磨される動翼外径最端部分の範囲を示す斜面 部を示す。Reference numeral 5 denotes an inclined surface portion showing the range of the outermost end portion of the outer diameter of the moving blade to be chip-polished by the grinder.
【００１３】 ６はチップ研磨用養生テープで、動翼先端形状と同形状に構成されており、グ ラインダーによる動翼先端のチップ加工時図３に示すように動翼１先端に形成し た凹部４内に嵌り込む状態で貼られ、各冷却穴３を塞ぐ。Numeral 6 is a curing tape for chip polishing, which is configured in the same shape as the tip of the moving blade, and when the tip of the blade is processed by a grinder, as shown in FIG. 3, a concave portion formed at the tip of the moving blade 1. It is affixed in such a manner that it fits into the inside of each of the cooling holes 4, and closes each cooling hole 3.
【００１４】 この結果チップ加工時発生する研磨カスが冷却穴３内へ混入することを防ぐ。As a result, it is possible to prevent polishing debris generated during chip processing from entering the cooling hole 3.
【００１５】 チップ研磨用養生テープ６の材質は柔軟性、成形性に富む材料を用い、かつ簡 単に接着可能なものが好適である。As the material for the chip polishing curing tape 6, it is preferable to use a material that is rich in flexibility and formability and that can be easily bonded.
【００１６】[0016]
本考案によれば、ガスタービン動翼のチップ研磨の際、単に動翼先端に形成さ れた凹部に嵌り込む状態でテープを貼るだけで、動翼の冷却穴を加工時発生する 研磨カスから保護でき、作業の大巾な時間短縮と、正確な養生が達成される。 According to the present invention, at the time of chip polishing of a gas turbine blade, by simply pasting a tape in a state that it fits into a recess formed at the tip of the blade, the polishing residue generated during processing of the cooling hole of the blade is eliminated. Can be protected, greatly shorten the work time, and achieve accurate curing.
