Zero-moment fitting

摘要

Apparatus, systems, and methods provide for a zero-moment fitting for securing a fluid conduit to a structure. According to various embodiments, a fitting may include a spherical bearing and a bearing housing. The spherical bearing may include a conduit aperture for receiving a fluid conduit through the spherical bearing. The bearing housing may be configured to encompass and retain the spherical bearing within the bearing housing, allowing for rotation of the spherical bearing within the bearing housing. The bearing housing may be fixedly attached to the structure to secure the fitting to the structure.

主权项

1. A structural fitting, comprising:
a spherical bearing comprising a front bearing and a rear bearing, wherein the front bearing and the rear bearing each comprise a conduit aperture encircled by an exterior bearing surface and traversing from the exterior bearing surface through a bearing inner face such that abutting the bearing inner face of the front bearing against the bearing inner face of the rear bearing creates an assembled bearing configuration having a bearing conduit aperture defined by each conduit aperture of the front bearing and the rear bearing and configured to receive a fluid conduit traversing the spherical bearing, and wherein a longitudinal axis of the spherical bearing traverses through the bearing conduit aperture parallel with the fluid conduit and substantially normal to the bearing inner face of the front bearing and the bearing inner face of the rear bearing in the assembled bearing configuration; and a bearing housing configured to retain the spherical bearing within the bearing housing, to allow for rotation of the spherical bearing within the bearing housing, and to be fixedly coupled to a structure.
