Problems solved by technology

For marine underwater gear boxes, the dynamic seal between the box and the drive mechanism plays an important role. If the seal is damaged, the external seawater will invade the box and cause damage to the drive components. The leakage of internal mineral oil will not only pollute the marine environment, It will also cause a lot of waste of resources
[0003]In addition, the long-term contact of mineral oil to the sealing material will also cause problems such as aging and damage. It is necessary to provide a seal that has oil-proof function and can resist high-pressure impact Pad structure, which has important application value for underwater ship sealing

Abstract

The invention relates to an oil-proof and high-impact-resistant U-shaped sealing gasket for an underwater ship. The body of the oil-proof and high-impact-resistant U-shaped sealing gasket is of a flexible U-shaped sealing ring structure, the contact surface of the outer side of the flexible U-shaped sealing ring and seawater integrally extends to form a nitrile rubber lip body, an oil-proof sealing layer is additionally arranged on the contact surface of the inner side of the flexible U-shaped sealing ring and mineral oil, and a plurality of unit buffer oil-proof nitrile rubber particles are arranged on the surface of the oil-proof sealing layer. The oil-proof and high-impact-resistant U-shaped sealing gasket for the underwater ship is scientific and reasonable in design and simple in structure, is arranged between a mineral oil surface structure and a sea water surface structure of a ship gearbox, the contact surface of the outer side of the flexible U-shaped sealing ring and seawaterintegrally extends from to form the nitrile rubber lip body, the oil-proof sealing layer is additionally arranged on the contact surface of the inner side of the flexible U-shaped sealing ring and mineral oil, so that the oil-proof and high-impact-resistant functions of an underwater ship gear box sealing element are effectively improved, the sealing effect is ensured, and meanwhile, the servicelife is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber sealing and relates to underwater sealing technology, in particular to an oil-proof, high-impact-resistant U-shaped sealing gasket for underwater ships. Background technique [0002] The gear box is widely used in the drive between mechanical parts, and its structure is composed of a box body, a driving gear and a number of driven gears arranged inside the box body. For marine underwater gear boxes, the dynamic seal between the box and the drive mechanism plays an important role. If the seal is damaged, the external seawater will invade the box and cause damage to the drive components. The leakage of internal mineral oil will not only pollute the marine environment, It will also cause a lot of waste of resources. [0003] In addition, long-term contact of mineral oil to sealing materials will also cause problems such as aging and damage. Providing a gasket structure with oil-proof function and hig...
