Hydraulic Anti-torque Cylinder for Shield Tunneling Machines Introductions

A Hydraulic Anti-torque Cylinder for Shield Tunneling Machines is a crucial hydraulic component that transmits torque from the primary drive to the cutter head of a shield tunneling machine (TBM). This function prevents the cutter head from rotating counter to the main drive, which can lead to damage or cause the TBM to become immobilized.

These Anti-torque Cylinders are commonly employed in TBMs with bore diameters ranging from 330mm to 570mm. Their rod diameters vary from 260mm to 530mm, with strokes between 120mm and 160mm. They are capable of operating under pressures reaching up to 35MPa, with a maximum pressure limit of 42MPa.

The Anti-torque Cylinders play an essential role in the operation of TBMs, ensuring that the cutter head rotates smoothly and consistently. This consistency is vital for the efficiency of the TBM and the safety of the personnel working with it.

Benefits of Using Anti-torque Cylinders

• Enhance the safety and efficiency of tunneling operations
• Minimize the risk of accidents
• Prolong the lifespan of the tunneling machine
• Reduce maintenance costs

How Anti-torque Cylinders Work?

The Hydraulic Anti-torque Cylinder is connected to the cutter head of the shield tunneling machine on one end and to the main bearing on the other end. When the cutter head rotates, it activates the piston within the cylinder, transmitting torque to the main bearing. The cylinder relies on hydraulic fluid to generate the necessary force for torque transmission.
