Abstract
The invention relates to marine equipment, in particular to improvement on a fin rotation device in a ship fin stabilizer device. The marine fin rotation device of the fin stabilizer comprises a fin box, wherein a fin base is mounted in the fin box; a fin shaft and a rotating vane type hydraulic device are mounted on the fin base, and the fin shaft can rotate around the axis of the fin shaft in the fin base; a fin wing is mounted on the fin shaft on one side of the fin base, and forms a fin together with the fin shaft; the fin shaft on the other side of the fin base is mounted in a shaft hole of the rotating vane type hydraulic device; a gap is formed between the inner wall of the shaft hole in the rotating vane type hydraulic device and the outer wall of the fin shaft distributed in the shaft hole. The marine fin rotation device can automatically adapt to the offset fin shaft axis, and is simple in structure and easy to implement, normal operation of the fin rotation device is ensured, and the service life of the fin rotation device is prolonged.
Description
Technical field
The present invention relates to marine equipment, relate in particular to the improvement of ship stabilization fin apparatus transfer fin apparatus.
Background technology
When boats and ships run into stormy waves in the navigation process, can produce the phenomenon of lateral oscillation, the lateral oscillation of boats and ships can reduce the navigability of boats and ships, the injured vessel body structure, affect equipment, the normal operation of instrument, also can cause displacement of goods or bump to damage, passenger and crewman are swooned, may affect its fighting capacity to combat vessel, in order to reduce the lateral oscillation of boats and ships, many colleagues conduct in-depth research, present effect preferably terms of settlement is at the turn of the bilge of boats and ships stabilizer and control setup thereof to be installed, control setup is by measuring the angle of boats and ships lateral oscillation, and the fin axle that goes to control stabilizer in conjunction with control signal of the factors such as speed of the ship in meters per second output is around the angle that its axis rotates, and wherein drives device that stabilizer rotates around the axis of fin axle and is called and turns fin apparatus.The present fin apparatus that turns adopts rotary vane type hydraulic device driving fin axle to clockwise rotate or rotate counterclockwise mostly, thereby changes the angle of the fin wing in seawater.Stabilizer in real work because the factors such as vibration, water impact and wearing and tearing can cause producing between the parts gap, the off normal of certain angle can occur in the fin axle, and present rotary vane type hydraulic device does not possess axis off normal function, so the off normal of fin axle is easily damaged the rotary vane type hydraulic device, preferably solution is arranged not yet at present.
Summary of the invention:
For the prior art above shortcomings, the objective of the invention is to provide a kind of stabilizer peculiar to vessel to turn fin apparatus, it can adapt to the off normal of fin axle axis automatically, assurance turns the fin apparatus normal operation, prolong the service life that turns fin apparatus, and simple in structure, easily realize.
In order to solve the problems of the technologies described above, the scheme that the present invention solves its technical matters is: stabilizer peculiar to vessel turns fin apparatus, comprise the fin case, in this fin case the fin seat is installed, fin axle and rotary vane type hydraulic device are installed on the described fin seat, described fin axle can rotate by the axis around described fin axle in described fin seat, the fin wing and described fin axle and the described fin wing are installed on the described fin axle of described fin seat one side consist of fin, the described fin axle of described fin seat opposite side is installed in the axis hole of described rotary vane type hydraulic device, the inwall of described rotary vane type hydraulic device central axis hole and be distributed between the outer wall of the described fin axle in the described axis hole gapped.
After adopting such scheme, owing in the fin case fin seat being installed, fin axle and rotary vane type hydraulic device are installed on the fin seat, the fin axle can rotate in the fin seat, the fin wing and fin axle and the fin wing are installed on the fin axle of fin seat one side consist of fin, the fin axle of fin seat opposite side is installed in the axis hole of rotary vane type hydraulic device, the inwall of rotary vane type hydraulic device central axis hole and be distributed between the outer wall of the fin axle in the axis hole gapped, so the axis off normal of fin axle causes the fin axle in the axis hole of rotary vane type hydraulic device during deflection, the fin axle does not contact with the inwall of the axis hole of rotary vane type hydraulic device, thereby the fin axle can not cause damage to the rotary vane type hydraulic device, actv. has guaranteed to turn the fin apparatus normal operation, and can prolong the service life that turns fin apparatus.
The structure that the stabilizer of this scheme turns fin apparatus is simple especially, with low cost, and easily realizes, good reliability,
The rotary vane type hydraulic device is made of rotary vane type oil cylinder and the stator with rotating vane that is installed in the oil cylinder, and stator center is provided with the axis hole that the fin axle is installed, and the fin axle passes the end that axis hole is installed in the rotary vane type hydraulic device.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the present invention stabilizer peculiar to vessel being turned fin apparatus further describes.
Fig. 1 is the structural principle schematic diagram that the present invention stabilizer peculiar to vessel turns fin apparatus.
The specific embodiment:
Among Fig. 1, fin seat 3 is installed in (the fin case is not shown in FIG.) in the fin case, fin axle 2 and rotary vane type hydraulic device 5 are installed on the fin seat 3, fin axle 2 can rotate by the axis around fin axle 2 in fin seat 3, the fin wing 1 and fin axle 2 and the fin wing 1 formation fin are installed on the fin axle 2 of fin seat 3 one sides, the fin axle 2 of fin seat 3 opposite sides is installed in the axis hole 7 of rotary vane type hydraulic device 5, the inwall 6 of rotary vane type hydraulic device 5 central axis holes 7 and be distributed between the outer wall 4 of the fin axle 2 in the axis hole 7 gapped, so work as because vibration, the factor such as water impact and wearing and tearing makes and produces the off normal that the gap causes fin axle 2 generation certain angles between the parts, so that fin axle 2 is in the axis hole 7 of rotary vane type hydraulic device 5 during deflection, fin axle 2 does not contact with the inwall 6 of the axis hole 7 of rotary vane type hydraulic device 5, thereby fin axle 2 can not cause damage to rotary vane type hydraulic device 5, actv. has guaranteed to turn the fin apparatus normal operation, and can prolong the service life that turns fin apparatus.
The structure that the stabilizer of this scheme turns fin apparatus is simple especially, with low cost, and easily realizes, good reliability,
