Variable orientation control for stator blades of turbine, - has orientation controlled by lever, which is operated by control ring.

摘要

The turbine is formed around a static frame with stages of pivoting, non-rotating blades (5), each of which has a pivoting control lever (36). A single control ring (20) carries the pivot control levers by an articulated joint. The pivot control lever is connected at one end to the bush (7), which is arranged to pivot around the axis of the blade, causing the blade to pivot under the control of the lever (36). The other end of the lever is connected to the control ring (2) by means of the hollow pivot (37), which is arranged to rotate within the bearing (38). USE/ADVANTAGE - It provides a simple and practical method to provide different angles of pivot for the blades of each stage of the turbine.
