Technical Field

[0001] The utility model relates to the technical field of flange shafts, in particular to a high-toughness marine flange shaft. Background Art

[0002] A marine flange shaft is a drive shaft specially designed for use in a ship's propulsion system. It is usually made of high-quality steel to withstand the high loads and harsh conditions in the marine environment. This type of shaft is characterized by one or more flanges at its ends, which usually have round holes so that it can be fixedly connected to other components (such as propellers, gearboxes, etc.) by bolts or pins.

[0003] An existing Chinese patent (publication number: CN218971690U) discloses a flange shaft, comprising: a flange seat, a fixed shaft body, the fixed shaft body being installed on the top of the flange seat, a driving adjustment mechanism, the driving adjustment mechanism being arranged on the fixed shaft body, the driving adjustment mechanism comprising a fixed groove and an annular groove, the fixed groove being opened on the top of the fixed shaft body, a connecting shaft being movably connected to the groove at the bottom of the inner wall of the fixed groove through a bearing, a threaded rod being installed on the top of the connecting shaft, and a movable shaft body being arranged inside the fixed groove.

[0004] In the above technical solution, the length of the flange shaft can be adjusted as needed through the mutual cooperation of the fixed groove, annular groove, connecting shaft, threaded rod, movable shaft body, connecting groove, movable plate, top block, rotating block, rotating shaft, driving gear and driven gear. However, the fixation of the device on the ship is not firm enough and the toughness is low. Since the propeller is connected to the power system of the ship through the flange shaft, if there is a problem with the fixing of the flange shaft, it may cause problems with the alignment of the propeller, affecting the navigation efficiency of the ship and the stability of power transmission. Therefore, we propose a strong and tough marine flange shaft. Utility Model Content

By setting the oil filling hole 6, oil is injected into it, and the lubrication between the bearing 2 and the flange 1 is increased, thereby extending the maintenance cycle of the equipment and reducing the maintenance frequency. By setting the anti-reverse component 8, when the oil contacts the end cover 81, the elastic material connector 82 is used to make the end cover 81 open to only one side to prevent the oil from flowing back. By setting the card slot 9 and the screw 10, the connection plate 31 can be fixedly connected to the hull, so that the flange 1 is fixed to the hull. By setting the sealing gasket 5, the small gap between the sealing surfaces of the flange 1 is effectively filled, thereby blocking the medium leakage channel and achieving an excellent sealing effect. By setting the bolt 12, the toughness of the connection between the device and the hull is increased.
