Fixing inter blade platforms on hub by means of pins

摘要

The platform has a deflecting part with an inner face having a fixation leg. The leg has an opening for the passage of a fixing pin. The pin has a rod with a threaded part having a diameter (D1) and another part with a sub-part. The sub-part has a diameter (D2) greater than the diameter (D1). Another sub-part extending the former sub-part has a diameter (D3) which is smaller than the diameter (D2) for traversing the opening. An independent claim is also included for a vane support disc.
