Bearing supporting trunnion for e.g. two-shaft turbofan, has tangential blocking units for blocking sealed box with respect to trunnion, where blocking units are arranged in downstream on longitudinal part

摘要

The trunnion (100) has a solid radial annular flange (132) arranged in an upstream on an axial cylindrical longitudinal part (130). The flange (132) is arranged in such a manner to butt with another radial annular flange of a sealed box. Tangential blocking units e.g. blocking ring (135), block the box with respect to the trunnion, and are arranged in a downstream on the longitudinal part. The blocking units include radial teeth (134) oriented towards inside and rotated with slots (131).
