Full-rotary device

Abstract

The invention discloses a full-rotary device. The full-rotary device is characterized by comprising a support sleeve, a rotary sleeve and a rotary transmission unit, wherein the rotary sleeve is in a hollow cylindrical shape, movably installed in the support sleeve, and can rotate around the axis; a drive shaft of an oar penetrates through the rotary sleeve and can rotate around the axis in the rotary sleeve; the rotary transmission unit comprises a set of worm and worm wheel and a set of sector gears, the worm and the worm wheel are installed on the support sleeve, one sector gear is mounted on a worm wheel shaft, the other sector gear is fixedly sleeved on the rotary sleeve, and the two sector gears are in engagement transmission; and the worm drives the worm wheel which drives the sector gear on the worm wheel shaft to rotate so as to drive the sector gear on the rotary sleeve to rotate. The full-rotary device has the advantages of being simple in structure, good in torsional vibration and rotary vibration resistance, reliable in performances and low in production and maintenance costs.

Description

technical field [0001] The invention relates to the field of ship propulsion systems, in particular to a full-turn device that integrates a traditional ship propulsion and a rudder, and can change the direction of the propulsive force of the ship propulsion, thereby changing the direction of travel of the ship. Background technique [0002] Existing rudders and oars are important components of a ship's propulsion system. The oars provide propulsion for the ship, and the rudder is used to control the direction of travel of the ship. In the prior art, the oars and rudders on ships are installed separately and work in combination. The direction of the propulsion force of the oars remains unchanged from that of the hull, and the rudder controls the direction. The best effect of force and direction makes the maneuverability and maneuverability of the ship insufficient. [0003] ZL201010522052.7 discloses a technical solution in which the rudder and the paddle are integrated. The...

Problems solved by technology

However, in this technical solution, the rotary motor directly drives the rotary gear, and there are the following problems: (1) In addition to providing rotary power, the rotary motor also needs to overcome the torque generated by the driving force of the boat, and this rotary device is not suitable for high-power ship propulsion systems; (2) ) When the ship is moving at high speed, the maneuverability of the rudder is insufficient, which will cause problems such as torsional vibration and rotary vibration, which will affect the working stability and service life of the transmission shaft system; (3) The high-power, high-strength driving gear and rotary gear The design and manufacturing requirements are extremely high, and the precision requirements are high; (4) The components of the slewing device have complex structures, high precision parts installation, and high manufacturing and maintenance costs
