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 seal device used on a propeller shaft of the yacht. Background technique [0002] The mechanical sealing device on the yacht propeller shaft is used to isolate the water from the electrical equipment on the yacht, which requires high sealing performance and reliability. [0003] From the current point of view, see the structure of the mechanical seal on the yacht propeller shaft image 3 , There are the following problems: 1) The centering shaft sleeve and the rubber bellows are prone to rotating and slipping when matched with transmission, resulting in seal leakage; 2) The static seal ring has no protection device, easy to wear, and low mechanical impact resistance. The service life is short. Summary of the invention [0004] Aiming at the deficiencies in the prior art, the present invention provides a sealing device with novel structure, good sealing performance and high mechanical impact resist...
