DEVICE FOR BENDING OSCILLATIONS DAMPING OF ROTATING SHAFT

摘要

FIELD: machine building.SUBSTANCE: inventions group relates to machine building. The dampening device (1) contains: supporting casing (6), element (11) with ring hole (12). The resilient device is located between the supporting casing and element. The element is made with possibility of movement relatively the supporting casing and radially relatively to axis (A) between the first and second position during the shaft bending relatively to the axis. The element is set to the first position when the hole is free crossed by the shaft. The element set to the second position upon interaction with the shaft. The shaft speed of rotation in the second range contains at least one critical shaft speed. The rod is made with possibility of movement together with the element radially to the axis. The plate is made as one piece with rod and transverse to it. The resilient device is located between the rod and the supporting casing. The resilient device contains the first spring and the second spring. The first spring is located between the first section of the supporting casing and element shoulder. The second sp[ring is located between the plate and second section of the supporting casing. The drive contains shaft operating in the second range of speed of rotation. The aircraft contains drive.EFFECT: better improvement of damping of the shaft bending oscillations.10 cl, 5 dwg
