Title:
VARIABLE STATIONARY BLADE DRIVE DEVICE AND AXIAL FLOW FLUID MACHINERY
Document Type and Number:
Japanese Patent JP2016156344
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a variable stationary blade drive device capable of smoothly driving a variable stationary blade.SOLUTION: A variable stationary blade drive device drives a variable stationary blade disposed inside a casing in which a rotor is accommodated. The variable stationary blade drive device comprises: a movable ring disposed around the circumference of the casing and movable in the rotational direction around the rotor axis of rotation; an actuator generating power for moving the movable ring; a shaft disposed in a bearing hole which is penetrating the casing and connected to the variable stationary blade; a lever disposed outside the casing and fixed to the shaft; a support part supported by the lever; a slide member having a slide part disposed in a recess provided in the movable ring; and a first elastic member disposed between the lever and the casing for generating a force to separate the lever from the casing.SELECTED DRAWING: Figure 4
