Problems solved by technology

But there are the following problems: (1) In addition to providing the rotary power of the propeller rudder, the rotary motor also needs to overcome the torque generated by the propeller driving force. When the ship is traveling at high speed, the maneuverability of the rudder is insufficient, and torsional vibration, rotary vibration, etc. Problems affect the working stability and service life of the slewing system; (2) There are too many parts in the propulsion power system meshing transmission, and the transmission efficiency is low; (3) The design and manufacture of high-power, high-strength drive gears and slewing gears are extremely demanding , high precision requirements; (4) many parts, complex structure, high precision parts installation, high manufacturing and maintenance costs

Abstract

The invention discloses a full rotary type oar-rudder which comprises a support sleeve, a rotary system, and a power propulsion system. The support sleeve is fixedly mounted on a ship body. The rotary system comprises a rotary sleeve, a worm and worm wheel transmission case, and a group of conical gears. The power propulsion system comprises a motor, a drive shaft, propellers, and a gear case body. The full rotary type screw-rudder is reasonable in structure, direct input of motor power and the drive shaft is realized through a way of combination of an oar and an rudder, and the propellers can rotate around the vertical axis in any direction of 360 degrees. A full rage of maximum thrust and efficiency can be obtained through controlling and pushing each rotary angle of the propellers, and maneuverability and agility of a ship can be greatly improved.

Description

Technical field [0001] The invention relates to the field of ship propulsion systems, in particular to a rudder with no traditional meaning, but a full-rotating propeller that can change the direction of the ship by changing the direction of the propeller's thrust. Background technique [0002] The existing rudders and propellers are an important part of the ship's propulsion system. The rudder is used to control the direction of the ship, and the propeller provides propulsion for the ship. In the prior art, the propeller and rudder on the ship are installed and combined separately, and the direction of the propeller's propulsion remains unchanged from the hull. The angle of the rudder rotation is sometimes not in place, and the maximum thrust and steering effect cannot be obtained. Insufficient sex and mobility. [0003] ZL201010522052.7 discloses a technical solution in which the rudder and the propeller are integrated. The intermediate transmission slewing device can change the...
