Abstract

The utility model discloses a ship screw propeller drive device. The utility model is characterized in that the utility model comprises a drive shaft and a first shaft sleeve arranged coaxially and fixedly on the drive shaft, a plurality of first supporting bars which are distributed uniformly are arranged on the first shaft sleeve, a second shaft sleeve is sleeved coaxially on the drive shaft, the second shaft sleeve is arranged on the side surface of the first shaft sleeve in parallel, a second supporting bar corresponding to the first supporting bar is arranged fixedly on the second shaft sleeve, a flexible propeller blade is arranged between the first supporting bar and the second supporting bar, each flexible propeller blade is arranged in the identical direction, and a shaft reversing drive device is arranged on the drive shaft. The utility model has the advantages that when the ship meets the dangerous situation and is required to be fallen back peremptorily, if only the direction of the flexible propeller blade is contrary to the original direction, the whole screw propeller device is turned reversely, the time of the whole process is very short, and the conversion between positive turning and negative turning is not required, the purpose that the ship is driven in the reverse direction is achieved, the middle time interval can be eliminated, to cause the ship to be fallen back quickly, and the accident which can happen possibly is avoided.

Description

A kind of propeller driving device of boats and ships

Technical field

The utility model relates to the device on a kind of boats and ships, especially relates to a kind of propeller driving device of boats and ships.

Background technology

From ancient times till now so that, in people's life, all can't do without the usefulness boats and ships as transportation means, and all boats and ships will lean on all actuating device just can travel in the future.The actuating device of existing ship mainly comprises screw propeller and rudder plate two parts, promotes boats and ships to overtake when screw propeller just changes, and rudder plate then is used for controlling the travel direction of boats and ships; When boats and ships need retreat, must at first allow screw propeller stop just to change, and then the counter-rotating could allow boats and ships retreat, need the regular hour between this; Generally speaking, this actuating device can guarantee the cruising of boats and ships, but running into that there are dangerous situations such as obstacle the front and when needing all back,emergency, this actuating device stops just to change in the process of reversing at screw propeller, boats and ships are because action of inertia can continue long to overtake segment distance, this causes unexpected loss and injures and deaths with regard to probably running into obstacle etc. and have an accident.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of propeller driving device that can make the boats and ships of the rapid rotating of screw propeller.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of propeller driving device of boats and ships, it comprises axle drive shaft and coaxial first axle sleeve that is fixedly installed on the described axle drive shaft, described primary shaft puts and is set with a plurality of well-distributed first strut bars, coaxial second axle sleeve that is arranged with on the described axle drive shaft, described second axle sleeve is set up in parallel the side at described first axle sleeve, be set with on described second axle sleeve and cooresponding second strut bar of described first strut bar, be provided with flexible blade between described first strut bar and described second strut bar, each described flexible blade is provided with in the same way, and described axle drive shaft is provided with the axle sleeve reverse driven gear.

Described axle sleeve reverse driven gear comprises commutation driven wheel and coaxial first gear and second gear that is arranged on the described axle drive shaft, described commutation driven wheel is connected with gear driven mechanism, described commutation driven wheel is provided with the commutation shift fork, described commutation shift fork is connected with the exchange system of boats and ships, described first gear is fixedly installed on the described axle drive shaft, described second gear is connected with the described second axle sleeve one, described commutation driven wheel and described first gear are meshing with each other, be wholely set first locating piece on described first gear, be wholely set two second locating pieces on described second gear, described first locating piece is arranged between described second locating piece.

Described first axle sleeve comprises first internal axle sleeve and first outer shaft that is mutually permanently connected, be provided with first connecting bore between described first internal axle sleeve and described first outer shaft, the lower end of described first strut bar is wholely set the first up-narrow and down-wide contiguous block, described first contiguous block and described first connecting bore cooperatively interact, described second axle sleeve comprises second internal axle sleeve and second outer shaft that is mutually permanently connected, be provided with second connecting bore between described second internal axle sleeve and described second outer shaft, the lower end of described second strut bar is wholely set the second up-narrow and down-wide contiguous block, and described second contiguous block and described second connecting bore cooperatively interact.

Compared with prior art, the utility model has the advantages that because axle drive shaft is provided with the axle sleeve reverse driven gear, as long as make commutation driven wheel and first gear or second gear mesh by control commutation shift fork, just can drive first axle sleeve or second axle sleeve rotates, the direction of flexible blade is changed, therefore when running into dangerous situation and need all back,emergency, as long as make the direction of flexible blade opposite with original direction, just can make the counter-rotating of whole propeller device, the whole process time spent is very short, and the conversion that does not need the screw propeller positive and reverse steering just can reach the purpose of reverse drive boats and ships, time gap in the middle of having eliminated, boats and ships can be retreated by fast speed, avoided contingent accident.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, a kind of propeller driving device of boats and ships, it comprises first axle sleeve 1, second axle sleeve 2, first gear 4, second gear 3, commutation driven wheel 6, axle drive shaft 5, first axle sleeve, 1 coaxial being fixedly installed on the axle drive shaft 5, first axle sleeve 1 is provided with a plurality of well-distributed first strut bars 15, first axle sleeve 1 comprises first internal axle sleeve 11 and first outer shaft 12 that is mutually permanently connected, be provided with first connecting bore 13 between first internal axle sleeve 11 and first outer shaft 12, the lower end of first strut bar 15 is wholely set the first up-narrow and down-wide contiguous block 14, first contiguous block 14 and first connecting bore 13 cooperatively interact, second axle sleeve, 2 coaxial being set on the axle drive shaft 5, second axle sleeve 2 is set up in parallel the side at first axle sleeve 1, second axle sleeve 2 is provided with and first strut bar, 15 cooresponding second strut bars 21, the connection mode of second strut bar 21 and second axle sleeve 2 is identical with the connection mode of first strut bar 15 and first axle sleeve 1, be provided with flexible blade 8 between first strut bar 15 and second strut bar 21, each flexible blade 8 is provided with in the same way, second gear 3 is connected with second axle sleeve, 2 one, first gear, 4 coaxial being fixedly installed on the axle drive shaft 5, be wholely set first locating piece 41 on first gear 4, two second locating pieces 31 have been wholely set on second gear 3, first locating piece 41 is arranged between second locating piece 31, the commutation driven wheel 6 and first gear 4 are meshing with each other, commutation driven wheel 6 is connected with gear driven mechanism 9, commutation driven wheel 6 is provided with commutation shift fork 7, and commutation shift fork 7 is connected with the exchange system (not shown) of boats and ships.
