摘要： PURPOSE:To enhance the reliability of a rotor blade by fitting a ceramic blade having a dove-tail shape root part, in a metal disc or a shank, and by lowering the rigidity of end parts of a pad so as to restrain stress concentration in the contact end parts. CONSTITUTION:Each of pads 3 intervening between a ceramic blade 1 and a shank 2 is thinned around its contact end parts. Accordingly, the rigidity of opposite end parts of the pad 3 which are contact end parts lowers and according the contact end parts of the pad 3 does not become a part where a significant stress point exists even though a centrifugal force is applied to the ceramic blade 1 during nominal operation so as to avoid damaging the blade. Instead of thinning the end parts of the pad, grooves may be formed in the end parts of the pad, or only the end parts of the pad may be made of materials having a low rigidity.

摘要： PURPOSE:To prevent a recessed part provided for fitting a ceramic blade root part with a shank part from being deformed to be opened by centrifugal force caused by operation, and to control the gap clearance on the tip end of the ceramic blade. CONSTITUTION:In a moving blade structure wherein ceramics having high thermal resistance is used for a part of a moving blade, a recessing part provided for fitting a ceramic blade root part with a shank part is restricted from being deformed to be opened by centrifugal force during operation, and wedge- shaped parts 6 are arranged between mutually adjacent shank parts 5. Moreover, the parts 6 are displaced in the direction of radius of gyration of a rotor caused by centrifugal force during operation, thereby force is applied to the recessed part of the shank part 5 in the direction for closing the recessed part. Moreover, high-temperature lubricant having heat resistance is applied to the contact surface between the shank part 5 and the wedge-shaped parts 6. And both sides of the shank are restrained by shank shells (side plates 7, 8).

摘要： PURPOSE:To improve reliability of strength by directly fitting a ceramic moving blade into a metal wheel through a process of providing a taper groove on the outer peripheral part of a side plate for covering blade root both sides of a moving blade so as to insert a wire therein and holding the wire between the taper groove and a platform side surface to be formed at the root of the moving blade by means of rotational centrifugal force. CONSTITUTION:A ceramic moving blade is integrally formed by a blade part 401, a platform part 402 and a blade root part 403. The blade root part 403 is in contact with a wheel 405. There is a front side plate 406 on the combustion gas inflow side of the blade root part 403, while there is a back side plate 407 on the outlet side. A taper groove 409 is provided on the outer peripheral part of the front side plate 406 so as to insert a wire 410 therein. The wire 410 comes in contact with the end of the platform part 402 by centrifugal force so as to prevent cooling air from leaking. Cooling air cools the wheel 405, the blade root part 403 and the platform part 402 and then flows out. By this structure, the ceramic moving blade can be directly fitted into a metallic wheel, and reliability of strength is improved. Moreover a large amount of cooling air is not required.

摘要： PURPOSE:To provide a ceramic gas turbine blade fixing device which can prevent uneven and excessive local contact stress and can resist long time rated operation. CONSTITUTION:A layer having a lubricating function is arranged on at least one surface among a fitting groove side surface 7, which is formed in a dovetail structure consisting of a rotor disc fitting groove 6 and a gas turbine blade 3 to be inserted into the fitting groove 6 or in a dovetail structure provided with an insertion plate 8 between the fitting groove 6 and the gas turbine blade 3, a gas turbine side surface 4, and both surfaces of the insertion plate 8. The layer 5 having a lubricating function is formed by sticking a material provided with a lubricating property or filling the material provided with a lubricating property in a recessed part, arranged on the base material surface. Therefore, uneven and excessive local contact stress can be completely eliminated because of existence of the layer provided with a lubricating function, so that a ceramic gas turbine blade fixing device which can withstand rated operation for a long time can be accomplished.
