ABSTRACT:
A swivel joint having improved bearing and seal life includes a pair of annular inner members each rotatably mounted in the bore of an annular sleeve with the ends of the inner members spaced from each other. An overrunning clutch between a first inner member and the sleeve allows the first inner member to rotate in a first direction relative to the sleeve, but prevents rotation in a second direction. Another overrunning clutch between the sleeve and the second inner member allows the sleeve to rotate in the second direction relative to the second inner member, but prevents rotation in the first direction. Bearings and seals mounted between the sleeve and the first inner member experience unidirectional rotation in the first direction and bearings and seals between the sleeve and the second inner member experience unidirectional rotation in a second direction. The overrunning clutches prevent oscillatory motion of the seals and bearings, and decreases wear and failure of the seals and bearings.
