Abstract
The invention discloses a novel rudder pushing mechanism for a ship. A body comprises four oil cylinders, two plunger pistons and a rudder tiller. The oil cylinders are arranged on two parallel axes, and every two corresponding oil cylinders are arranged on the corresponding axis in a left-and-right mode and share the corresponding plunger piston; an installing plane is milled on the inner side of each plunger piston and is matched with the back face of a rack, and the racks are of U-shaped structures; the rudder tiller is arranged between the two plunger pistons and provided with sector gears engaged with the racks. The novel rudder pushing mechanism has the advantages that the novel rudder pushing mechanism is simple and reasonable in structure, low in cost and long in service life; when the oil pressure of the oil cylinders is constant, the torque output to the rudder tiller is constant, the movement of the plunger pistons can be linearly converted into rotation of the rudder tiller, and moving accuracy is high; the maximum value of a rotating angle of the rudder tiller can be determined through design, and can be larger than 45 degrees of the present design; as long as the plunger pistons are lengthened, the rotating angle of the rudder tiller can be 90 degrees and even larger.
Description
Technical field
The present invention relates to equipment of Vessel technical field, particularly a kind of New Marine steering mechanism.
Background technology
Steering wheel is the large deck machinery of one on boats and ships.The size of steering wheel is determined by the specification of deck outfitting according to classification society, mainly considers torque during type selecting.
What steering wheel traditional at present pushed away rudder structure employing is that slide block pushes away rudder, namely slide block is contained on the slide block pivot pin of plunger, plunger can be with movable slider to move together, there is some shortcomings part: 1) slide block is arranged in the fork groove of tiller, move mode with the slide block of plunger movement promotes fork groove, tiller is rotated, and is the nonlinear relationship of trigonometric function form between movement with amount of spin; 2) slide block is in the fork groove of tiller, has both promoted groove and has rotated, slided again along groove, so slide block size is less than groove, gap between the two reduces kinematic accuracy; 3) application stress between slide block and groove face is large, and slide block is easy to wear, for reducing wear, adopt high brass as slide block, and from external import, cost is higher; 4) by fork type steering mechanism structural limitations, steering corner is maximum can only accomplish one-sided about 45 °.
Summary of the invention
The present invention is to provide that a kind of steering mechanism output torque is invariable in oil pressure one timing, and rotating speed is uniform, and realizes plunger and move the New Marine steering mechanism rotating linear transformation with tiller.
The technical solution used in the present invention is:
A kind of New Marine steering mechanism, main body comprises four oil cylinders, two plungers and tiller, its innovative point is: described oil cylinder is arranged on two parallel axis, every bar axis is provided with two oil cylinders in left and right, a plunger is shared between two oil cylinders, the inner side of described two plungers mills out a mounting plane, described mounting plane matches with the back side of tooth bar, described tooth bar is concave structure, be provided with tiller between described two plungers, described tiller is provided with the elevating arc be meshed with described tooth bar.
Beneficial effect of the present invention is as follows:
1) the present invention is simple and reasonable, cost is lower, long service life, cylinder oil one timing, the output torque of tiller is invariable;
2) can be the rotation of tiller the sex reversal of plunger portable cord, speed of coming about be even, and kinematic accuracy is high;
3) maxim of the corner of tiller can be determined by design, can be greater than current 75 °, as long as locus is enough, plunger long enough, can make the corner of tiller be greater than 75 °, until 90 °, even larger.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural representation of the present invention.
Drawing reference numeral: 1-oil cylinder, 2-plunger, 21-mounting plane, 3-tiller, 4-tooth bar, 5-elevating arc.
Detailed description of the invention
A kind of New Marine steering mechanism as shown in Figure 1, main body comprises four oil cylinders, 1, two plungers 2 and tiller 3, described oil cylinder 1 is arranged on two parallel axis, every bar axis is provided with two oil cylinders 1 in left and right, a plunger 2 is shared between two oil cylinders 1, the inner side of described two plungers 2 mills out a mounting plane 21, described mounting plane 21 matches with the back side of tooth bar 4, described tooth bar 4 is concave structure, be provided with tiller 3 between described two plungers 2, described tiller 3 is provided with the elevating arc 5 be meshed with described tooth bar 4.
The groove of tooth bar provides the space of the screw head of consolidation bolt, making compact conformation, in order to make tooth bar engage well with elevating arc, pad can be added between the tooth bar back side and the mounting plane of plunger, regulate the thickness of pad, what tooth bar was engaged with elevating arc is better; Further, in frame, scale can be set place parallel with plunger, even scale, the corner amount of mark tiller.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
