Flange and wind energy system

摘要

A flange is provided including a longitudinal axis defining a first direction, a radial direction being substantially perpendicular to the first direction, a neck extending along the first direction, a flange plate connected to the neck and including a connecting portion adapted for holding a connecting device at a connecting side, the flange plate further including a non-connecting side being at a radially different location than the connecting side; the flange including a first plane defining a first level of the neck, a second plane defining a second level, where flange plate and neck are connected, and a third plane defining a third level of the flange plate, wherein the three planes extend substantially perpendicular to the longitudinal axis of the flange; the flange includes at least at the non-connecting side a bulge, which extends from a level between the first plane and the second plane to the third plane.

主权项

1. A flange including a longitudinal axis, comprising:
a neck extending substantially along the longitudinal axis of the flange defining a first direction; a flange plate connected to the neck and including a connecting portion configured to hold a connecting device at a connecting side, the flange plate further including a non-connecting side being at a radially different location than the connecting side; the flange including a first plane defining a first level of the neck, a second plane defining a second level where the flange plate and the neck are connected, and a third plane defining a third level of the flange plate, wherein the first plane, the second plane and the third plane extend substantially perpendicular to the longitudinal axis of the flange; and a ring-shaped bulge on the non-connecting side of the flange, wherein the bulge extends from a fourth level of the neck to the third plane, the fourth level being located between the first plane and the second plane, a merge point of the bulge and the neck comprises a flange fillet, and an outer diameter of the bulge is substantially constant along the non-connecting side.
