Problems solved by technology
Due to the continuous rotation of the force transmission ring, the soil and the outer peripheral wall of the large diameter section of the force transmission ring and the hole wall of the small diameter hole of the force transmission ring, the outer peripheral wall of the hatch of the power cabin, and the hole wall of the ring groove on the outer end face of the sealing retainer are constantly frictioned, causing The outer peripheral wall of the hatch of the power cabin, the outer peripheral wall of the large-diameter section of the force transmission ring, the hole wall of the small-diameter hole of the force transmission ring, and the hole wall of the ring groove on the outer end face of the sealing retainer are severely worn, and the worn part cannot be used in the tunnel. Rework, which seriously affects the service life of the power cabin, force transmission ring and seal retainer

Embodiment Construction
[0021] The shield cutter head mechanism of the shield tunneling machine of the present invention is mainly composed of a cutter head drive mechanism, a connecting leg 8 and a cutter head 9 . The cutter head driving mechanism is mainly composed of a driving motor 1 , a power cabin 2 , a transmission gear 3 , a gear ring 4 , a power transmission ring 5 and a sealing retainer 6 . The power cabin 2 is the heart of the entire cutter head drive mechanism, and all power is transmitted from the power cabin during shield construction. The drive motor 1 is installed on the power cabin 2, the transmission gear 3 and the large ring gear 4 are arranged in the power cabin 2, the transmission gear 3 is installed on the output end of the drive motor 1, and the transmission gear 3 is meshed with the large ring gear 4 for transmission. The force ring 5 is arranged on the inner periphery of the hatch of the power cabin. The force transmission ring 5 is fixedly connected to the outer end of the ...
