CA 2643773
The invention relates to a method for attaching a bearing (7) on a turbomachine comprising a stator and a rotor, the bearing (7) including: - a first portion (73) attached on the stator of the turbomachine by a plurality of screws (80) and nuts (85), - a second portion (74) attached on the rotor, rotationally movable in one given rotation direction, and - a rolling bearing (70) provided between the first (73) and second (74) portions of the bearing. The problem addressed by the invention is that of improving the attachment of the bearing (7) by making it more reliable and more robust, particularly against unscrewing. In order to solve this problem, the method provides using screws (80) having a screwing rotation direction contrary to the rotation direction of the rotor.
