摘要： A shaft-grounding stuffing box cover (10) includes an annular nut-base (12) that includes a central aperture (14) through which a rotating shaft (16) passes. Two grounding tabs (28 and 30) project longitudinally upwards from the proximal end of the nut-base (12) adjacent the rotating shaft. The grounding tabs include diametrically opposed radial openings (18) that are longitudinally displaced from each other for the mounting of conductive brush contacts (20) therein. The conductive brush contacts are biased against the rotating shaft by backing springs (46), and are retained within the radial openings by hollow bolts (48). The hollow bolts, spring, and brush contacts form an electrically conductive path to the rotating shaft for grounding of the shaft.
