Abstract

PURPOSE:To prevent any breakage accident of a turbine bucket by positioning a contact face formed on the blade root part of the bucket and a contact face formed on a shroud part in mutually opposite directions. CONSTITUTION:Contact faces 21, 22 which are inclined in response to a blade part 3 are provided on the blade root part 2 of a bucket 1. Also, contact faces 41, 42 which are inclined in the opposite direction to the contact faces 21, 22 on the blade root part 2, are provided on a shroud part 4. Though a torsional return is generated in the shroud part 4 due to centrifugal force, it acts as interference together with torsional return force affecting adjacent buckets so as to strengthen their contact condition. Consequently, any breakage accident due to looseness can be prevented.
