定ｌ装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Objective of the invention) (Industrial application field) The present invention provides a hardness measuring device suitable for measuring the hardness of the inner wall of a center hole in, for example, a turbine or a 1 yen JI 11 rotor. Regarding.
（従来の技術）
例えばタービンのロータには、軸方向に延びる中心孔が
穿設されている。この中心孔の内壁は、ロータ製造時に
探ａ！試験が行なわれて、ｅ等の有、 無が検査される
。(Prior Art) For example, a rotor of a turbine has a center hole that extends in the axial direction. The inner wall of this center hole was inspected during rotor manufacturing. A test is conducted to check for the presence or absence of e, etc.
一方、タービンロータが＾温の温度領域で使用されると

しい部位はタービンロータの中心孔内壁であるため、こ
の中心孔内壁の硬さ測定は非常に矩型である。On the other hand, if the turbine rotor is used in a temperature range of ﾆ temperature, creep and thermal fatigue damage may accumulate in the turbine rotor over a long period of use, leading to material deterioration and cracking. Therefore, when inspecting the turbine, we conduct flaw detection on the outer surface of the turbine rotor and the inner wall of the center hole, and also conduct a hardness test to determine material deterioration.
The safety of the turbine rotor has been confirmed. In particular, in the turbine rotor, the part where the greatest stress occurs and the material deteriorates significantly is the inner wall of the center hole of the turbine rotor, so the hardness of the inner wall of the center hole is very rectangular.

の反発速麿を電気的に計測して、各点の硬さを計測する
ものである。Conventional hardness measuring devices for measuring the hardness of the inner wall of the center hole of a turbine rotor are based on the principles of the Vickers hardness tester and the Prinnell hardness tester, and both measure one point at a time. be. For example, JP-A-57-17124
The inner surface hardness tester disclosed in Publication No. 3 measures the hardness at each point on the inner wall of the center hole by pressing an indenter against the inner wall of the center hole of the rotor and measuring the amount of indentation. In addition, the rotor hardness measuring device disclosed in Japanese Patent Publication No. 57-84336 electrically measures the repulsion speed of a J3G indenter at each point to measure the hardness at each point. It is something.

の硬さ測定装置では、計測に際し計測面の表面状態を確
認できないので、計測時の信ぴょう性に欠けるおそれが
ある。In these conventional hardness measuring devices, the indenter must be moved once to measure the hardness of one point. Therefore,
To measure the axial hardness distribution on the inner wall of the center hole of a turbine rotor, it is necessary to measure the fractures at many points, and therefore visual measurement takes a lot of time. Furthermore, with conventional hardness measuring devices, the surface condition of the measurement surface cannot be confirmed during measurement, so there is a risk that reliability during measurement may be lacking.

There are drawbacks.
