摘要： PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of reducing combustion vibration in combustion.
SOLUTION: This gas turbine combustor comprises an acoustic liner widely surrounding a combustion area of a combustion chamber regardless of presence or absence of a connection pipe and a bypass duct, to effectively reduce the combustion vibration. Further a height of an acoustic case of the acoustic liner and a size of acoustic holes formed on a wall of the combustion chamber are adjusted to have the acoustic attenuation property to a wide frequency band. The bypass duct can be installed on a part on which the acoustic line is mounted, a mixing ratio of fuel and air can be constantly kept regardless of the load of a gas turbine, NOx emission can be reduced, the air introduced into the combustion chamber is introduced through the acoustic holes uniformly formed in the circumferential direction of the combustion chamber, and a distribution of the temperature of the combustion gas blown out from the combustion changer to a downstream can be unified. A cooling passage, a cooling hole or an impingement hole may be formed on the wall of the combustion chamber and a rib when necessary, thus the gas turbine combustor of high reliability can be provided.

摘要： PROBLEM TO BE SOLVED: To perform fastening with reliability even when large load is applied. SOLUTION: A rod member 4 penetrates through casing members 1, 2, 3 to be fastened. An upper end of the rod member 4 is engaged with an upper surface of the easing member 1 through an upper nut 6 screwed therewith. A lower end of the rod member 4, with which a lower nut 5 is screwed, is projected downward of the easing member 3. Push-up bolts 10 are screwed into bolt holes 9 formed on a peripheral edge of the lower nut 5. After screwing the push-up bolts 10, a divided spacer 11 is press-fitted into a gap between a lower washer 8 and the lower nut 5. Load is supported while being distributed by the push-up bolts 10 and the spacer 11 having a large pressure receiving area.

摘要： PROBLEM TO BE SOLVED: To prevent wasteful wear of a clutch shoe when it is not pinched by a top disc and a bottom disc. SOLUTION: A clutch shoe 14 is levitated by the resilient force of a leaf spring 23 and separated from a bottom disc 16 when the shoe 14 is not pinched by a top disc 15 and bottom disc 16. A core material 21 is of aluminum, and friction material 22 is fixed to its oversurface and undersurface. The side faces of the core material 21 are subjected to a hard positive electrode oxide film forming process. The clutch shoe 14 has a long circular shape and is arranged in two rows, outside and inside in radial direction of a clutch disc 13, wherein the clutch shoe 14 in the outer row is positioned so that its longitudinal direction is identical to the above-mentioned radial direction and the one in the inner row is positioned so that its longitudinal direction is inclined 45 deg. to the radial direction. Thereby the torque of a flywheel in a screw type device is transmitted to the screw shaft.

摘要： PROBLEM TO BE SOLVED: To increase a rate of operation and enhance forging quality. SOLUTION: A flywheel driving mechanism 10 normally rotates a flywheel 12. Making a clutch shoe 14 a clutch ON state transmits the torque of the flywheel 12 to a screw shaft 2. Normally rotating the screw shaft 2 lowers a nut 3 threadedly engaged with the screw shaft 2 to lower a metal mold 7 toward a metal mold 9 for machining. After completing the machining, the clutch shoe 14 is put in a clutch OFF state. A hydraulic cylinder advances the rack 202a of a screw reverse rotating mechanism 200. Thus, a pinion 201 is reversely rotated to reversely rotate the screw shaft 2, and the nut 3 is raised.
