A cutter head torque input structure for shield machine

Abstract

The invention discloses a cutter head torque input structure for a shield tunneling machine. The cutter head torque input structure for the shield tunneling machine comprises a motor, a speed reducer, an inner gear rotation support and a torque input gear supporting structure. The torque input gear supporting structure comprises a torque input gear, a front tapered roller bearing, a rear tapered roller bearing and a supporting base, wherein the torque input gear is meshed with an inner gear ring of the inner gear rotation support, an inner ring of the front tapered roller bearing and an inner ring of the rear tapered roller bearing are connected with the front end and the rear end of the torque input gear respectively, and are arranged inside an installation hole of the supporting base together, the inner wall of the rear side of the supporting base is connected with the inner gear rotation support, and the motor, the speed reducer and the torque input gear are in transmission connection in sequence. The cutter head torque input structure for the shield tunneling machine is reasonable in structure, and can be conveniently assembled, replaced and overhauled in a narrow construction tunnel.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a cutterhead torque input structure for a shield machine. Background technique [0002] With the rapid development of modern society, the pace of life is accelerating, and people's demand for travel is also increasing. Due to the sharp increase in car ownership, various traffic and social problems have been caused. s Choice. As the main form of underground transportation, underground tunnels are highly valued by everyone for their construction efficiency, technicality, and safety. Nowadays, the construction of underground tunnels generally adopts large-scale shield machines for excavation and excavation, and at the same time uses the method of precast concrete segment support. This method is fast and efficient, has a high degree of mechanization, has little impact on the environment, and can guarantee the construction quality of the tunnel. [0003] The cutter head torq...
