Description

Technical Field

[0001] The utility model relates to a clutch, in particular to a shield machine clutch with a rust-proof structure, belonging to the technical field of shield machines. Background Art

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The clutch is a commonly used component in mechanical transmission. It can separate or engage the transmission system at any time, temporarily separate and gradually engage the engine and gearbox, so as to cut off or transmit the power input from the engine to the transmission.

[0003] The announcement number is CN219432308U, which is a clutch assembly based on the soft start of the shield machine cutter disc, including a clutch body, a heat dissipation assembly and a buffer assembly. During use, when the user steps on the clutch pedal, the clutch pedal will drive the driven shaft to move, the driven shaft movement will then drive the release bearing to move, the release bearing movement will then cause the moving plate to move, the moving plate movement will then squeeze the pressure rod, so that the pressure rod drives the pressure plate to lift up, so that the friction plate is separated from the flywheel disc, thereby realizing the power transmission and realizing the soft start of the clutch.

[0004] However, in actual use, when the clutch pedal is stepped on, the clutch pedal will drive the driven shaft to move, and the movement of the driven shaft will in turn drive the release bearing to move, thereby realizing power transmission. However, the clutch must be cleaned before installation, and there must be no oil or impurities. Since there is no seal on the outside of the clutch body, long-term contact with water vapor in the air will cause rust on the clutch body, and the rust will greatly reduce the life of the clutch body. In addition, there is no seal on the outside of the clutch body, which will cause foreign matter to enter the clutch body, thereby causing damage to the clutch body. For this reason, we provide a shield machine clutch with a rust-proof structure. Utility Model Content

[0005] The utility model provides a shield machine clutch with an anti-rust structure to solve the problem that the clutch must be cleaned before installation and must be free of oil stains and impurities, and that since the clutch body has no seal on the outside and is in contact with water vapor in the air for a long time, rust spots will appear on the clutch body, and the rust spots will greatly reduce the life of the clutch body.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a shield machine clutch with a rust-proof structure, comprising an upper shell and a lower shell, the upper outer wall of the upper shell is provided with a sliding groove, the interior of the sliding groove is provided with a clutch handle, the front of the lower shell is provided with a passive shaft, the rear of the passive shaft is provided with a front bearing, and the front bearing is installed on the lower shell;

[0007] A sealing edge is fixedly installed at the connection between the upper shell and the lower shell, a sealing fixing hole is opened on the outer wall of the sealing edge, and a fixing screw is installed on the inner wall of the sealing fixing hole.

[0008] As a further solution of the utility model: a handle limit pin is connected to the lower part of the clutch handle, a limit ring pin is connected to the lower bottom end of the clutch handle, and a front limit block is installed outside the clutch handle and the handle limit pin.
