Abstract
The utility model relates to a non-rudder plate propulsion device of a ship. Through changing a driving pipe into a two-section type and relative rotation structure, the propulsion direction of a propeller blade can be adjusted, and through directly controlling the propulsion direction by a controlling mechanism, the rudder and a reverse gear can be saved. The structure is simplified, the cost is reduced and the semi diameter of the underwater cornering of the ship body is reduced.
Description
Technical field
The utility model relates to a kind of boats and ships does not have the rudder plate propelling unit, belongs to Int.clB
63Technical field under the H.
Background technology
In the prior art, boats and ships travel and direction control is controlled respectively by propelling unit and steering gear respectively.Wherein, be equipped with in propelling unit generally comprises upper box, the positioned vertical of speed-changing mechanism and engaging and disengaging gear main driving axle, be fixedly installed in the nowel axle that passes through the horizontal setting that two cone gears engagements drive in the lower box and be installed on the screw blade of this shaft rear end; Steering gear then comprises joystick, drive disk assembly and rudder plate.Two parts are separate.
Summary of the invention
The utility model aims to provide a kind ofly can reduce the prior art cost, boats and ships simple in structure do not have the rudder plate propelling unit.
The utility model adopts following technical scheme.
The upper box of speed-changing mechanism in comprising, the utility model is housed, be positioned at the main driving axle of upper box below positioned vertical, be set in the transmission tube in the main driving axle outside, lower box, be installed on the perpendicular intermeshing cone gear of two axis in the lower box, nowel axle and be installed on the screw blade of this shaft rear end, above-mentioned two cone gears are installed on respectively on main driving axle and the nowel axle, the power of power take-off implement output drives main driving axle through described speed-changing mechanism and rotates, and then thereby two cone gears that are meshed by the lower end drive nowel axle and screw blade and rotate and promote boats and ships and advance, it also comprises joystick and drive disk assembly, it is characterized in that: described transmission tube is formed by two sections with flexible connection that coaxial inner conductor can relatively rotate, two sections make lower box can produce relative twisting with last lower box captive joint respectively, and the described drive disk assembly that is connected with joystick is connected in lower box or is fixedly connected on that section transmission tube of lower box.
Inventive concept of the present utility model be change in the prior art transmission tube two ends respectively the upper and lower casing of captive joint make that the pushing direction of screw blade is always changeless, the control of boats and ships direction must depend on rudder plate, change by the transmission tube structure makes that the direction of propulsion of screw blade is adjustable and outgoing direction steering unit direct control changes, can simplified structure and save rudder plate.
In the above-mentioned technical solution, the two sectional type structure of transmission tube is varied, is formed by two sections suits of size as transmission tube, and the internal diameter of wherein big section pipe is greater than the external diameter of segment pipe, and is loaded on the segment pipe by two bearing carrier rings.
The utility model has saved rudder plate and reverse gear mechanism, simplifies the structure, saved cost greatly, and can reduce the turn radius under water of hull.
