Abstract

The invention discloses a sealing device with novel style construction, good sealing property, high mechanical shock resistance, the construction includes a shaft sleeve, a moving ring base, a moving ring, a stationary component. A sealing member is arranged on internal side of the shaft sleeve, a moving ring base is arranged on bottom of the shaft sleeve pushed by an elastic component at middle, a moving ring is arranged on top of the moving ring base, the stationary component is arranged above the moving ring, a locking device is arranged on top of the shaft sleeve. The invention has advantages of a relative rotation preventing device arranged on the moving ring base and the shaft sleeve, good sealing property of the sealing device and high mechanical shock resistance.

Description

technical field [0001] The invention relates to a yacht, in particular to a mechanical sealing device used on the propeller shaft of the yacht. Background technique [0002] The mechanical seal device on the yacht propeller shaft is used to isolate the water from the electrical equipment on the yacht, and requires high sealing performance and reliability. [0003] From the current point of view, the structure of the mechanical seal device on the yacht propeller shaft is shown in Fig. image 3 , there are the following problems: 1) The centering shaft sleeve and the rubber bellows are prone to rotation and slippage when they cooperate with the transmission, resulting in seal leakage; 2) The static seal ring has no protection device, is easy to wear, and has low mechanical shock resistance. Short service life. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the invention provides a sealing device with novel structure, good sealing performance...
