Assembly arrangement between an inner bearing ring and a trunnion, bearing ring and trunnion adapted to the arrangement, and a turbo machine equipped with them

摘要

The arrangement has an annular groove (36) arranged on an outer side (24) of a journal (2) comprising an axis (4), and an annular groove (26) arranged on an inner side (66) of an inner ring (6). The grooves cooperate to form an annular channel (52) between the journal and the ring. A rod (40) is inserted in the channel to prevent a relative axial translation movement, along the axis, between the journal and the ring. A recess (38) of the journal and a tooth (32) of the ring cooperate to prevent a relative rotational movement, around the axis, between the journal and the ring.
