Rotor for a turbomachine
First Claim
1. A rotor for a turbomachine, said rotor comprising:
- a hub including a peripheral surface, a first side surface, and a second side surface, said hub defining a plurality of cavities, each one of said cavities extending inwardly from said peripheral surface, said hub defining a plurality of openings, each one of said openings extending from a corresponding one of said cavities to at least one of said first side surface and said second side surface; and
a blade coupled to said hub, said blade including an end portion fitting in a particular one of said cavities and screwably secured to said hub, a particular one of said openings extending from said particular one of said cavities being adapted to receive a constraint element engaging said end portion, said particular one of said openings extending between said first side surface and said second side surface, said particular one of said openings having a first section and a second section, said second section extending between said second side surface and said particular one of said cavities, said first section being aligned with said second section and extending to said first side surface.

Abstract
A rotor for a turbomachine. The rotor comprises a hub including a peripheral surface, a first side surface, and a second side surface. The hub defines a plurality of cavities, each one of the cavities extending inwardly from the peripheral surface. The hub also defines a plurality of openings, each one of the openings extending from a corresponding one of the cavities to at least one of the first side surface and the second side surface. The rotor further comprises a blade coupled to the hub. The blade includes an end portion fitting in a particular one of the cavities and screwably secured to the hub. A particular one of the openings extending from the particular one of the cavities is adapted to receive a constraint element engaging the end portion.
