Device for handling a shaft forming a pivoting link between at least two parts

A method for handling a shaft having an orifice emerging at its center and forming a hollow shaft and a link between first and second parts, by means of a handling device comprising a body extending along a longitudinal axis and having a threaded outer portion and a bore extending along the longitudinal axis, a threaded rod inserted into the bore of the body and having first and second ends, a butterfly nut screwed onto the first end of the threaded rod, an expandable clamping ring arranged on the second end of the threaded rod, a compression nut comprising a washer comprising notches and a locknut screwed onto the threaded outer portion of the body and comprising notches of a form complementing a form of the notches of the washer, a bearing member positioned against one of the first or second parts, and return means positioned between the washer and the bearing member, the method comprising the steps of:

• inserting the body into the orifice;
• screwing the butterfly nut onto the threaded rod along the longitudinal axis in a second direction to deform the expandable clamping ring and to block a translation of the body with respect to the shaft along the longitudinal axis in a first direction opposite the second direction;
• translating the washer along the longitudinal axis in the second direction to compress the return means;
• screwing the locknut to make the notches of the locknut cooperate with the notches of the washer and block the translation of the washer along the longitudinal axis in the first direction;
• and
• rotating the washer about the longitudinal axis to make the notches of the washer slip against the notches of the locknut to decompress the return means in the second direction.
