Abstract
The utility model relates to a glass reinforced plastic fish boat power transmission device, in particular to a glass reinforced plastic boat propeller shaft device. The device comprises a mermaid frame, a propeller shaft and a spiral paddle, wherein the propeller shaft is fixed to the inside of the mermaid frame through a bearing, one end of the propeller shaft is connected with an output shaft of an internal combustion engine, and the other end of the propeller shaft is connected with the spiral peddle. The device is characterized in that a protection sleeve is arranged on the propeller shaft between the mermaid frame and the spiral paddle in a sleeved mode, one side of the protection sleeve is connected with the mermaid frame through a flange, and the other side of the protection sleeve is at least provided with two symmetric protruding cutting edges. In the rotation process of the propeller shaft, the bearing is cooled by both a propeller shaft hole and a water-pervious hole; when wires, fishing nets and algae are wound around the propeller shaft, the device has the advantages of being simple in structure, convenient to install, capable of effectively protecting the propeller shaft against being entangled and the like.
Description
Technical field
The present invention relates to fiberglass fishing boat torque transfer, be specifically a kind of easy for installation, use safety, antiwind ferry glass reinforced plastic boat stern tube shaft device.
Background technology
We know, ferry glass reinforced plastic boat is due to corrosion resistance and good, the advantage such as easy to maintenance, be used widely in recent years, glass reinforced plastic yacht particularly, speedboat is widely used in coastland, glass reinforced plastic yacht, the engine installation of speedboat generally adopts diesel oil or gasoline engine, driving device generally adopts screw propeller, diesel oil or gasoline engine have two kinds with the transfer mode that is connected of screw propeller now, a kind of is the outboard engine form of screw propeller and rudder, it is due to inconvenient operation, the reasons such as chaufeur labour intensity height are mainly used in coastal waters aquaculture, main employing is with the stern tube shaft mode of stern tube shaft and rudder now, the stern tube shaft of this mode is fixed on beauty's frame of hull bottom through bearing, stern tube shaft one end connects internal-combustion engine output shaft, the stern tube shaft other end is connected with propeller, engine drives propeller rotation through stern tube shaft, to drive advancing or retreating of ships and light boats, but, the stern tube shaft of this structure is easy to by the biology in water, the threads such as rope and fishing net are wound around, strengthen the load of stern tube shaft, in addition, stern tube shaft bearing easily makes heat radiation not in time because being wound around, very easily there is burning phenomenon.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of easy for installation, use safety, good heat dissipation effect ferry glass reinforced plastic boat stern tube shaft device that effectively the anti-stern tube shaft of order is wound.
The present invention can reach by following measure:
A kind of ferry glass reinforced plastic boat stern tube shaft device, comprise beauty's frame, stern tube shaft and screw propeller, stern tube shaft is in bearing is fixed on beauty's frame, one end of stern tube shaft is connected with internal combustion engine output shaft, the stern tube shaft other end is connected with the slurry drum of propeller, it is characterized in that the stern tube shaft cover between beauty's frame and propeller has protecting jacket, protecting jacket one side is connected with beauty's frame through flange, and protecting jacket opposite side is at least provided with two symmetrical protruding blades.
Protecting jacket of the present invention is provided with permeable hole, derives in time the heat that bearing produces.
The back side of propeller blade of the present invention is provided with the anti-tangle cutter of strip, and the blade of anti-tangle cutter is towards the tangential direction of propeller blade.
The present invention in stern tube shaft rotary course, bearing cooling by stern tube shaft hole and permeable hole shared, when stern tube shaft is wound with cotton rope, fishing net and marine alga, have simple in structure, easy for installation, effectively protect the advantages such as stern tube shaft is not wound.
Accompanying drawing explanation.
Fig. 1 is a kind of schematic diagram of the present invention.
The specific embodiment.
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, a kind of ferry glass reinforced plastic boat stern tube shaft device, comprise beauty's frame 1, stern tube shaft 2 and screw propeller 3, stern tube shaft 2 is in bearing is fixed on beauty's frame 1, one end of stern tube shaft 2 is connected with internal combustion engine output shaft, stern tube shaft 2 other ends are connected with the slurry drum of propeller 3, the structure of above-mentioned each component part and the interconnected relationship between them are same as the prior art, this does not repeat, the stern tube shaft cover that the invention is characterized in 3 of beauty's frame 1 and propeller has protecting jacket 4, protecting jacket 4 one sides are connected with beauty's frame 1 through flange, protecting jacket 4 opposite sides are at least provided with two symmetrical protruding blades 5, protecting jacket 4 of the present invention is provided with permeable hole, derive in time the heat that bearing produces, in addition, the back side of propeller blade 3 of the present invention is provided with the anti-tangle cutter 6 of strip, the blade of anti-tangle cutter 6 is towards the tangential direction of propeller blade, the present invention is in stern tube shaft rotary course, bearing cooling by stern tube shaft hole and permeable hole shared, when stern tube shaft is wound with cotton rope, when fishing net and marine alga, have simple in structure, easy for installation, effectively protect the advantages such as stern tube shaft is not wound.
