Abstract
The utility model discloses a marine screw propeller driving device which comprises a screw propeller component and a rudder plate. The screw propeller component is mounted between an upper fixing seat and a lower fixing seat of a ship stern, which is characterized in a driving reverse device. The driving reverse device screw mounted on the propeller component has the advantages that the screw propeller rotates 180 degrees to back off urgently in a dangerous situation, the screw propeller drives the ship reversely without the conversion of positive and negative steering which eliminates the intermediate time intervals and backs off the ship quickly and the ship does not continue to run forward due to an inertia effect, thus avoiding the possible accidents.
Description
Technical field
The utility model relates to a kind of actuating device, 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 a segment distance to overtake, can not retreat, this causes unexpected loss and injures and deaths with regard to probably running into obstacle etc. and have an accident at once.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of propeller driving device that boats and ships are retreated rapidly.
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, comprise screw propeller assembly and rudder plate, described screw propeller assembly is arranged between the upper fixed seat and lower fixed seat of hull afterbody, and described screw propeller assembly is provided with the driving reversing arrangement.
Described screw propeller assembly comprises central actuating shaft and propeller drive shaft, the upper end of described central actuating shaft is passed described upper fixed seat and is connected with the drive system of boats and ships, described driving reversing arrangement comprises the coaxial outer sleeve that is set on the described central actuating shaft, described rudder plate is arranged on the described outer sleeve, the upper end of described outer sleeve is passed described upper fixed seat and is connected with the direct system of boats and ships, described lower fixed seat is provided with axis hole, described axis hole is stretched in the lower end of described outer sleeve, radially be provided with the screw propeller axle sleeve on the cylindrical shell of described outer sleeve, described propeller drive shaft is coaxial to be arranged in the described screw propeller axle sleeve, the outer end of described propeller drive shaft is provided with screw propeller, the lower end of described central actuating shaft is provided with drive bevel gear, the inner of described propeller drive shaft is provided with driven wheel of differential, and described drive bevel gear and described driven wheel of differential cooperatively interact.
Described rudder plate and described outer sleeve are bolted to connection.
Described axis hole is provided with clutch shaft bearing, and the lower end of described outer sleeve and described clutch shaft bearing cooperatively interact.
Described screw propeller axle sleeve is wholely set on described overcoat cylindrical shell, be provided with second bearing between described propeller drive shaft and the described screw propeller axle sleeve, the coaxial fixed cap that is arranged with on the described propeller drive shaft, described fixed cap is captiveed joint with the outer end of described screw propeller axle sleeve by bolt.
Compared with prior art, advantage of the present utility model is that the screw propeller assembly is provided with the driving reversing arrangement, can be when running into dangerous situation and need all back,emergency, make screw propeller Rotate 180 °, screw propeller does not need the conversion of positive and reverse steering just can reach the purpose of reverse drive boats and ships, and the time gap in the middle of having eliminated can retreat by fast speed boats and ships, and can not continue to overtake because of effect of inertia, avoided contingent accident.
