]DEVICE FOR ALIGNMENT OF PIPE IN TURBINE SHAFT Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: proposed device is designed for alignment of pipe or part inside hollow turbine shaft in turbine in which said pipe or part is rigidly connected by ends with shaft at rotation. It contains bushing rigidly connected with pipe or part and enclosing the latter, elastic ring and means providing expansion of ring after assembling. Elastic ring is installed between bushing and shaft and it contains pairs of shoes made radially outwards. Shoes have thin elastic cylindrical walls whose diameter in nonworking state slightly differs from inner diameter of hollow shaft and which tightly fit inner wall of shaft after assembling.

EFFECT: possibility of reliable holding of pipe inside hollow shaft.
