A rotating split seal ring assembly comprises a seal ring (42) having a split (50) dividing the seal ring into at least two sections (42', 42") configured to fit around a shaft (10), clamp ring (44) having a split (51) dividing the clamp ring into at least two sections (44', 44") configured to circumferentially surround the seal ring, each clamp ring section having tabs (56) which cooperate with corresponding tabs on another clamp ring section to permit assembly of the clamp ring sections around the seal ring; and a housing (46) having a split (72) dividing the housing into at least two sections (46', 46") configured to fit around the shaft, the housing including first and second notches (70) having at least one converging angle side wall (figures 4 and 10) configured to receive and engage the tabs so as to prevent rotation of the clamp ring relative to the housing. Upon shaft rotation, the tabs each engage at least one converging angle sidewall to provide metal-to-metal contact between the tabs and the housing.

L'invention porte sur un ensemble bague d'étanchéité rotative fendue comprenant une bague d'étanchéité (42) divisée par une fente (50) en au moins deux sections (42', 42'') conçues pour s'adapter autour d'un arbre (10); une bague de serrage (44) divisée par une fente (51) en au moins deux sections (44', 44'') conçues pour entourer la bague d'étanchéité. Chaque section de la bague de serrage comporte des pattes (56) coopérant avec les pattes correspondantes d'une autre section de la bague de serrage, ce qui permet l'assemblage de ces sections autour de la bague d'étanchéité; et un corps (46) divisé par une fente (72) en au moins deux sections (46', 46'') conçues pour s'adapter autour de l'arbre, ce corps comprenant des première et seconde encoches (70) possédant une paroi latérale à angle convergent (figures 4 et 10) contre laquelle les pattes viennent en contact de façon à empêcher la bague de serrage de tourner par rapport au corps. Lors de la rotation de l'arbre, chacune des pattes vient en contact avec au moins une paroi latérale à angle convergent de manière à créer un contact métal contre métal entre les pattes et le corps.
