摘要： PURPOSE: To prevent a threaded part from breaking due to fatigue, by dispersing bending moment, which acts on a moving blade shaft, to be prevented from being transmitted to the threaded part of the moving blade shaft, by means of a pair of concentric ring-shaped tightening members having a tapered surface aligned and brought into contact with each other.
CONSTITUTION: A hub fitted to a rotary shaft provides in a rim part 24A a moving blade-shaft insertion hole 25 extending in a radial direction. A moving blade shaft 27 is inserted into this insertion hole 25. And the moving blade shaft 27, protruded to a reverse part 24B of the rim part 24A, forms a smooth round bar part 27B and a threaded part 27C successively with a step difference. The round bar part 27B assembles a pair of concentric ring-shaped tightening members 22, 23 having a tapered surface reducing its contour toward the point end part of a moving blade. And the moving blade is tightened by a tightening nut 28. The tightening members 22, 23 are constituted so as to tighten the moving blade by the wedge action in accordance with a level of centrifugal force acting on the moving blade.

摘要： PURPOSE:To prevent the reduction of the fatigue strength of a screw part by installing a holding member for holding a movable-vane shaft between a thrust bearing and a fastening nut and allowing only the lightened centrifugal force to act onto the screw part of the movable-vane shaft having the fastening-nut arranged. CONSTITUTION:A ring 60 is shrink-fitted onto a straight frictional fastening part 27C formed in the shaft part 27 of a movable vane, and a fastening nut 34 is arranged in a screw part 27D, and the ring 60 is fastened onto a thrust bearing 30. Since the movable-vane shaft part 27 is certainly fixed in the radial direction of the shaft part in the straight frictional fastening part 27C through the shrink-fit ring 60, the bending moment generated on the movable vane is transmitted to the thrust bearing 30 through the shrink-fit ring 60, and the bending moment transmitted to the screw part 27D becomes little, and further a part of the centrifugal force is born by the contact surface between the straight frictional fastening part 27C and the shrink-fit ring 60, and therefore, also a part of the centrifugal force acting onto the screw part 27D is lightened, and the reduction of the fatigue strength of the screw part 27D can be prevented.

摘要： PURPOSE:To provide a tightening structure which has excellent assembly efficiency through prevention of damage of a shaft, by a method wherein, in a device which tightens a body to be tightened such as gear against a shaft by means of a tightening tool with wedge effect, a spacer ring is placed between the tightening tool and the shaft. CONSTITUTION:When a shaft 1 and, for example, a gear 2 are tightened together by means of a tightening tool 3, with wedge effect a spacer ring 8 is located between the shaft 1 and the tightening tool 3. The spacer ring 8 may have the same width as that of the tightening tool 3, but the size, being about 2 times as long as the thickness of the ring, is more effective. This prevents damage of the surface of the shaft 1, caused by tightening effected by the use of the tightening tool 3, and provides a tightening structure having excellent assembly efficiency.

摘要： PURPOSE:To improve tightening reliability without an increase in the thickness wall of a hollow shaft, by a method wherein in a device which tightens an object to be tightened, such as gear, against the hollow shaft by means of a wedge effect tightening tool, a reinforcing body is interposed all the way through to the inner surface, positioned facing the tightening tool, of the hollow shaft. CONSTITUTION:When a gear 2 is tightened against a hollow shaft 1 by means of a wedge effect tightening tool 3, a reinforcing body 4 is placed to the inner surface, positioned facing said tightening tool 3, of the hollow shaft 1. An inner force, produced by the tightening tool 3, is received by the reinforcing body 4, and this prevents deformation, stress concentration, and fatigue strength from occurring at the part, positioned facing the tightening tool 3, of the hollow shaft 1. This naturally generates a high tightening force and provides a high-reliable tightening part.
