Abstract
A rotator mechanism for rotating an elongate member that is coupled to a reciprocating member of a pumping system includes: a body having a through-hole for receiving a portion of the elongate member; a first freewheel clutch configured to cause the elongate member to rotate incrementally about the body axis in a predetermined direction when the reciprocating member reciprocates; and a second freewheel clutch spaced from the first clutch and configured to prevent the elongate member from rotating opposite the predetermined direction when the reciprocating member reciprocates. One or both of the clutches includes circumferentially-spaced clutch elements, that may include rollers or sprags or both.
