Abstract:
1. A seal body for use with a torque tube, comprising: a first portion including an inward facing contact surface and an attachment mechanism to releasably secure the torque tube to the first portion; a second portion joined to the first portion, the second portion including a substantially uniplanar sealing surface defining a radial sealing plane that is orthogonal to an axis of rotation of the torque tube when the seal body is attached to the torque tube, the uniplanar sealing surface of the second portion and the inward facing contact surface of the first portion forming a substantially ninety-degree interior angle therebetween and defining a cylindrical cavity configured to receive an end of the torque tube; and a third portion axially opposite the first portion and the second portion and extending from a radially inward facing innermost circumferential surface defining a shaft opening, outward to an outermost circumferential surface, the third portion having an axially outermost surface defining a radial end plane and including a plurality of annular grooves configured for engagement with a seal ring, each of the grooves having a depth defined by a bottom groove surface; wherein the bottom groove surface of a deepest of the plurality of annular grooves defines a third radial plane that lies between the radial sealing plane of the uniplanar sealing surface and the radial end plane; wherein the plurality of grooves are located between the radial end plane and the third radial plane; and wherein the substantially uniplanar sealing surface extends across a substantially uniplanar axial end face of the torque tube when the seal body is attached to the torque tube.
