Mechanical seal assembly with improved support of axial forces

Abstract

The invention relates to a mechanical seal assembly (1) for sealing between a high-pressure region (8) and a low-pressure region (9) on a rotating component (7), comprising a mechanical seal (2) with a rotating slide ring (3) with a first slide surface (30) and a stationary slide ring (4) with a second slide surface (40), wherein a sealing gap (5) is defined between the slide surfaces (30, 40), a slide ring carrier (31) for the rotating slide ring (3), which is configured to connect the rotating slide ring (3) to the rotating component (7) in a rotationally fixed manner, wherein the slide ring carrier (31) comprises a sleeve region (32), and a force support arrangement (6), which is configured to support an axial force (F) acting on the mechanical seal assembly (1), wherein the force support arrangement (6) is arranged on an end face (32a) of the sleeve region (32) of the slide ring carrier (31), wherein the force support arrangement (6) comprises a clamping sleeve (60), a conical sleeve (61) and a split ring (62) with at least two segments (621, 622), wherein a conical connection with a first conical surface (60a) on the clamping sleeve (60) and a second conical surface (61a) on the conical sleeve (61) is formed between the clamping sleeve (60) and the conical sleeve (61), and wherein the clamping sleeve (60) bears against the end face (32a) of the sleeve region (32) and the conical sleeve (61) bears against a side surface (62a) of the divided ring (62).
