Background technology
The screw propeller of traditional propeller can only act on a direction, even controllable pitch propeller also can only be accomplished simple positive car and reversing, causes ship maneuverability poor.How to improve the operating characteristic of boats and ships, be the problem that people are concerned about always.Yet, need road-holding property or failure-free dynamicpositioning flexibly for berthing tug and some engineering ships of high maneuverability, and in the ship operation of power more than 1000HP, the thrust that presses for screw propeller can act on comprehensive.
The utility model content
The purpose of the utility model is: the practical problems of the road-holding property difference that exists in using to the present rudder oar system that comes about provides a kind of rudder oar worm and gear loof mechanism that can realize comprehensive adjustment.
The purpose of the utility model is achieved in that the mode of coming about that a kind of miniwatt rudder oar is provided.
The purpose of the utility model is achieved in that a kind of rudder oar worm and gear loof mechanism; Comprise the well case, casing and drive the lower tooth roller box of screw propeller cogs; It is characterized in that: also comprise worm gear, worm screw, the motor of coming about, the column of coming about in the loof mechanism, deep groove ball bearing, needle bearing; Described worm screw is supported on the casing that cogs by two tapered roller bearings, and worm gear is captiveed joint with the column of coming about through locating dowel pin or bolt, and the motor of coming about is positioned at the end of worm screw; The described column of coming about is captiveed joint with the casing of lower tooth roller box, and the input shaft of lower tooth roller box passes the column center of coming about and is connected with the upper gear box driven shaft; The column of coming about is positioned the well case through deep groove ball bearing, needle bearing.
In the utility model: described worm gear is through locating dowel pin and bolt is direct and the column of coming about
Captive joint.
In the utility model: the described column of coming about is positioned to be meant in the well case through deep groove ball bearing, needle bearing: well case of fixed installation on hull; The column of coming about places the well case; Coming about is provided with deep groove ball bearing between top and the well case of column, and coming about is provided with needle bearing between column bottom and the well case.
In the utility model: described worm gear and come about and be provided with lining between the column, worm gear is captiveed joint with lining through pin, and lining is captiveed joint with the column of coming about through pin.
In the utility model: the described motor of coming about is reversible constant displacement hydraulic motor.
The advantage of the utility model is: owing to adopt the worm-and-wheel gear under the CD-ROM drive motor control, can realize 360 ° of rotations easily, whole thrusts of screw propeller can act on any direction.360 ° of rotations of the casing of worm gear drives lower tooth roller box change the thrust direction of screw propeller, and the speed of coming about do not influence by the propeller thrust size, thereby obtain to advance the optimized matching with thrust direction; Owing at worm gear and come about and be provided with lining between the column, can reduce the weight of the column of coming about; Worm gear and lining can guarantee the accuracy of mesh of worm and gear through finger setting.The utility model compact conformation, easy to maintenance.
