Therefore, it is desirable to provide a rudder stock attachment that is simple in construction, safe and reliable.
Disclosure of Invention
The utility model aims at solving the technical problem and providing a connection structure of an aluminum alloy hull and a rudder stock protective sleeve with simple structure, safety and reliability.
In order to realize the technical purpose, reach foretell technical requirement, the utility model discloses the technical scheme who adopts is: connection structure of aluminum alloy hull and rudderstock protective sheath, including aluminum alloy sleeve, rudderstock, aluminum alloy base, its characterized in that: a protective sleeve is arranged in the aluminum alloy sleeve hole, a sliding bearing is arranged between the protective sleeve and the rudder stock, epoxy resin is arranged between the protective sleeve and the aluminum alloy sleeve and wraps the inner hole and the upper and lower ends of the aluminum alloy sleeve, and the end cover compresses the epoxy resin and the sliding bearing to be connected with the lower end face of the protective sleeve; the protective sleeve flange fastens epoxy resin on the upper end face of the aluminum alloy sleeve through bolts, and the protective sleeve flange is fixed on the aluminum alloy base through bolts.
Preferably: the slide bearing sets up clearance fit with the rudderstock, slide bearing sets up transition fit with the protective sheath.
Preferably: the protective sheath includes the upper flange, and the welding has the sleeve support below the upper flange, and the welding of sleeve support lower extreme has fixed cover.
Preferably: the upper end of the fixed sleeve is provided with a flange, and a boss matched with an inner hole of the sleeve support is arranged on the flange.
Compared with the traditional structure, the beneficial effects of the utility model are that: simple structure is reasonable, safe and reliable, and the protective sheath passes through flange joint hull, and firm in connection reduces the moment of flexure that the rudderstock received, is provided with the deviation that epoxy is convenient for adjust the direction of height between protective sheath and the aluminum alloy sleeve to sealing performance has been guaranteed.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of FIG. 1 at A;
FIG. 3 is a schematic view of the structure of the protective sheath of the present invention;
in the figure: 1. the novel rudder comprises an end cover, 2. an aluminum alloy sleeve, 3. epoxy resin, 4. a protective sleeve, 41. a fixed sleeve, 411. a flange, 43. a sleeve support, 44. an upper flange, 5. a rudder stock, 6. an aluminum alloy base, 7. a bearing seat, 8. a sliding bearing and 9. a mechanical seal.
Detailed Description
The present invention will be further explained below.
With reference to the accompanying drawings,
connection structure of aluminum alloy hull and rudderstock protective sheath, including aluminum alloy sleeve 2, rudderstock 5, aluminum alloy base 6, its characterized in that: a protective sleeve 4 is arranged in the hole of the aluminum alloy sleeve 2, a sliding bearing 8 is arranged between the protective sleeve 4 and the rudder stock 5, epoxy resin 3 is arranged between the protective sleeve 4 and the aluminum alloy sleeve 2, the epoxy resin 3 is coated in the inner hole and the upper and lower ends of the aluminum alloy sleeve 2, and the end cover 1 compresses the epoxy resin 3 and the sliding bearing 8 to be connected with the lower end face of the protective sleeve 4; the protective sleeve 4 is characterized in that the flange 411 fastens the epoxy resin 3 on the upper end face of the aluminum alloy sleeve 2 through bolts, and the upper flange 44 of the protective sleeve 4 is fixed on the aluminum alloy base 6 through bolts.
In the preferred embodiment, the sliding bearing 8 and the rudder stock 5 are arranged in a clearance fit, and the sliding bearing 8 and the protective sleeve 4 are arranged in a transition fit.
In the preferred embodiment, the protective sleeve 4 includes an upper flange 44, a sleeve bracket 43 is welded below the upper flange 44, and a fixing sleeve 41 is welded at the lower end of the sleeve bracket 43.
In the preferred embodiment, the upper end of the fixing sleeve 41 is provided with a flange 411, and a boss is arranged on the flange 411 to match with the inner hole of the sleeve bracket 43.
The utility model discloses a theory of operation: the upper end and the lower end of the protective sleeve are fixed by flanges, and the flanges bear torque. The two flanges are divided into an upper end and a lower end, so that the deviation of the height direction of the rudder stock protective sleeve can be adjusted, and the deviation can be adjusted by filling the space with epoxy resin. Outside the bottom plate of the ship, the end cover of the protective sleeve presses the whole epoxy resin section outside, so that the protective rudder stock protective sleeve can transfer impact force to the bottom plate of the ship when the protective rudder stock protective sleeve receives the upward impact force from the bottom. The upper flange can be used as a base of a rudder bearing on a roller of the rudder, so that the rudder bearing, a protective sleeve, a hull stringer and the like are all connected together, and torsion resistance can be improved. The lower flange of the protective sleeve is used as a supporting point, so that the bending moment borne by the rudder stock is reduced.
The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
