Description
Technical field
The present invention relates to a kind of screw propeller, the underwater screw propeller assembly of the band seal casing that especially a kind of transmission shaft of screw propeller is parallel with main driving axle.
Background technology
Screw propeller is the major part that ship is advanced, extraordinary relatively ship, traditional screw propeller is because the influence of structure can't be suitable as common ship, and common screw propeller itself can not rotate around transmission shaft, just the relativeness of screw propeller and transmission shaft can't change, and this installation and screw propeller rotation that can influence screw propeller produces power.
At amphibious vehicle, the degree of depth of screw propeller in water directly influences marine propulsion efficient, in general, the degree of depth of screw propeller is dark more good more, but can break during land locomotion, but if only guarantee that land locomotion does not bump screw propeller, when then travelling in the water, it is shallow excessively that blade position immerses the water surface, causes propulsive force to descend.
Summary of the invention
The purpose of this invention is to provide a kind of screw propeller rotating shaft underwater screw propeller assembly parallel with main driving axle.
Another object of the present invention provides between a kind of main driving axle and the screw propeller rotating shaft and prevents the into underwater screw propeller assembly of the issuable churning loss of water with the seal casing sealing.
A further object of the present invention provides a kind of screw propeller base portion and prevent to immerse the underwater screw propeller assembly that causes on site maintenance inconvenience in the water in amphibious vehicle.
The present invention solves its technical matters and adopts the ground technical scheme to be: a kind of underwater screw propeller assembly, comprise main body driving section and driven driving section, end in driven driving section is provided with screw propeller, and wherein, underwater screw propeller assembly is connected by conveyer with the trailing wheel rotating shaft of amphibious vehicle; The main body driving section is provided with the amphibious vehicle interlayer, and interlayer is divided into the outer part of partial sum in the amphibious vehicle with underwater screw propeller assembly, and expose outside the amphibious vehicle end of the main driving axle of main body driving section; Driven driving section links to each other by seal casing with the main body driving section, by power wheel the main driving axle of main body driving section and the auxilliary transmission shaft of driven driving section is linked to each other in the seal casing, and main driving axle and auxilliary transmission shaft are for being arranged in parallel; Screw propeller and main body driving section split the both sides at seal casing.Power transmission, is rotated thereby drive screw propeller by screw propeller assembly in-to-in structure the input shaft of transmission of power to screw propeller assembly by the conveyer bar to the rotating shaft of amphibious vehicle trailing wheel, realizes waterborne travelling; Auxilliary transmission shaft of screw propeller and main driving axle are arranged in parallel, and the transmission position at both installs seal casing, auxilliary transmission shaft band screw propeller and can be rotated around main driving axle, and screw propeller can be rotated at the different position behind ship, can select the most rational depth of immersion transferring power; Screw propeller assembly links to each other with amphibious vehicle by interlayer, and with the main body driving section of screw propeller assembly all the other all are placed in the amphibious vehicle amphibious vehicle except expose the end of main driving axle, can make things convenient in use and directly overhaul, not use under water owing to breaking down; And the weight of screw propeller assembly is born without attaching parts by the amphibious vehicle body substantially and is born more reasonable stress; Transmission in the seal casing realizes by belt wheel and belt, perhaps adopts sprocket wheel and chain or directly comes transmission by gear meshing.
Main driving axle bridges on two walls of seal casing, and is cooperating the installation position to be provided with bearing and sealing arrangement; Auxilliary transmission shaft bridges on two walls of seal casing, and is cooperating the installation position to be provided with bearing and sealing arrangement.The employing structure that bridges makes being connected of seal casing and transmission shaft stable, and more reasonable stress can be rotated screw propeller one end of seal casing around the main gear axle head.
Seal casing is elongated, and the two ends of seal casing are circular, and the diameter of driven driving section end circle is less than the diameter of other end circle.
Make propulsion source more reasonable with being connected of driving section for reducing installing space, main body is provided with input shaft in the driving section, and input shaft and main driving axle are arranged vertically, and the end of input shaft and the end of main driving axle are provided with intermeshing finishing bevel gear cuter.
The fitting surface of auxilliary transmission shaft and screw propeller is a conical suface, and the end of auxilliary transmission shaft is provided with screw thread.Screw propeller adopts conical suface to cooperate with auxilliary transmission shaft, it is tightr that screw propeller is contacted with auxilliary transmission shaft, increases friction force, and installation is also convenient, screw thread is set in the end of auxilliary transmission shaft is used for fasteningly, reversing and land walking jolt and prevent that screw propeller from deviating under the situation in the water.
Conveyer is made up of the little single wheel of the input shaft other end in the single wheel in the rotating shaft of amphibious vehicle trailing wheel, the main body driving section and both driving chains; Single wheel and little single wheel are arranged at grade.Driving chain in the conveyer can be replaced with base part with other, such as adopting belt to be suitable for high-revolving rotation, also can adopt and directly use gear transmission.
Seal casing can rotate around main driving axle.Realize the needs of screw propeller at differing heights, the angle that can adjust seal casing guarantees the depth of immersion of screw propeller.
The invention has the beneficial effects as follows: prevent the into issuable churning loss of water with the seal casing sealing between main driving axle and the auxilliary transmission shaft, raise the efficiency; Seal casing can be selected the most rational depth of immersion transferring power around the different parts work of main driving axle rotation adaptation at amphibious vehicle; Screw propeller assembly be divided in the amphibious vehicle and amphibious vehicle outside, convenient maintenance base portion is born weight by the amphibious vehicle body, stressed rationally; Screw propeller adopts conical suface to cooperate with auxilliary transmission shaft, and the convenient screw propeller of installing increases friction force; Control the depth of immersion of screw propeller by the anglec of rotation of adjusting seal casing.
