ニカルシールのトルク伝達装置。 The rotating seal element has a rotating seal element equipped with a rotating sealing ring that rotates simultaneously with the rotating member of the shaft-sealed device, and a fixed-side sealing element equipped with a stationary sealing ring that is fixed to the casing side of the shaft-sealed device. In a mechanical seal in which a sealing end surface of a ring and a stationary sealing ring are brought into sliding contact to form a shaft sealing part, a reinforcing ring is fitted and fixed to the outer periphery of the rotating sealing ring, and an annular retainer is attached to the rotating member via a torque transmission mechanism. The reinforcing ring and the annular retainer are engaged with each other via an engagement mechanism, and torque is transmitted from the annular retainer to the rotating sealing ring via the reinforcing ring. Mechanical seal torque transmission device.
