ABSTRACT:
A mechanical seal comprises a seating ring and a follower ring. The seating ring receives therethrough a rotatable shaft and forms a stationary member and the follower ring is rotated together with the rotatable shaft in sliding contact with the seating ring. The seal is serviceable for avoiding the leakage of pressurized sealed fluid from the outside of the sliding contact portion between both the rings to the inside thereof. At least one of the sliding contact surfaces of both the rings has an outside raised portion along the periphery of the sliding contact surface. The raised portion is swollen in the direction of the axis of the rotatable shaft as compared with the inside portion of the sliding contact surface. Since the contact surface pressure in the peripheral portion of both the rings becomes high at the normal temperature by the provision of the outside raised form, the sealing effect can be improved especially during the stoppage of the follower ring. When the follower ring is subjected to the frictional heat due to its rotation, the follower ring is deformed in the direction in which the contact surface pressure becomes even. Therefore, the effect of sealing during the rotation is also improved. ,,p
