    摘要: A hub and a member, the member having a central opening. The hub is received in the member central opening. The hub has a center, and a hub axis through the center. The hub also has a splined exterior with a plurality of splines, each spline having a spline surface, and the member central opening has internal splines that engage with the hub splined exterior. At least one of the hub splines has a wear indicator, the wear indicator comprising a surface mark that extends along a portion of the spline surface in the same direction as the hub axis.

    摘要: Embodiments of the inventive technology may provide a leaked fluid detection and response system in one aspect, and in another aspect, an environmental enclosure for at least a component of such leaked fluid detection system. Various embodiments of the leaked fluid detection and response system may provide wireless communication of detected leaks and a PLC that automates response and provides information regarding the presence of a leak. Enclosures may, in various embodiments, comprehensively surround enclosed components, thermally insulate enclosed components, include a leaked fluid capture basin, be aerodynamically streamlined, and/or be vermin-tight.
