    摘要: A mechanical face seal device includes a bellows assembly comprising a bellows member of resilient material having axially spaced mounting portions interconnected by an intermediate foldable portion, one of said mounting portions being adapted to be fixed relative to a rotary component whilst the other is in torque transferring relationship with a rotary annular seal member, and a biasing means for diasing the rotary annular seal member against the stationary annular seal member. An essentially stiff support member having a predetermined radial dimension is provided for axially supporting the rotary annular seal member and is itself supported by the bellows member. The bellows assembly further comprises a driving housing having axially spaced force transferring portions, of which one is in force transferring relationship with the mounting portion of the bellows member at the annular seal member side, whilst the other one is in force transferring relationship with the mounting portion at the rotary component side thereof, wherein the force transferring portion facing the mounting portion at the component side has an internal radial dimension which is less than the external radial dimension of the support member and greater than external radial dimension of the rotary annular seal member.
