Expandable sealed pivot system with component lock/unlock function

摘要

A sealed pivot assembly with lock/unlocking functionality has an axis member having a plurality of threaded openings formed in both a first and a second end member. A pair of locking sleeves is positioned over each of the first end and second end of the axis member. An expansion sleeves is positioned over each of the pair of locking sleeves. Locking devices are inserted into the openings formed in each end of the axis member, the locking devices engaging the pair of expansion sleeves causing the expansion sleeves to expand to secure the axis member in the mounting lugs. A threaded dismounting tool may be positioned in one threaded hole to force the axis member axially causing the expansion sleeves to loosen.
