Abstract

The utility model relates to a flap rudder transmission, which is composed of a main rudder, a rudder bar, a lower hinge, a flap, an upper hinge and a flap transmission mechanism, wherein, the main rudder is connected with a ship body through the rudder bar; the flap is connected with the main rudder through the upper hinge and the lower hinge; one component of the flap transmission mechanism is welded and fixed at the top of the flap, and the other component is hinged with a supporting seat which is welded and fixed in the ship body; the flap transmission mechanism can be a guide rod type, a slide slot type, a hinge type or a swinging rod type. The utility model is characterized in that the structure of the flap rudder transmission is largely improved; a fishing net or float in the water can not result in failures of the utility model; stainless steel material is adopted in a rotating shaft. The utility model has the advantages of simple structure, high strength, little possibility of damage, reliable use, etc., and the utility model can widely be used on river and sea transport ships, trolleys, operating ships, navy ships, etc.

Description

New Flap Rudder Gear

The utility model relates to a kind of New Flap Rudder Gear, is applicable to river, the defeated boats and ships of sea-freight, tugboat, operation boats and ships and army's ship etc.

Because flap can improve steerage, improves the manoeuvre of ship performance, improve the operation ability of boats and ships, be subjected to the extensive attention of domestic shipping community and shipbuilding circles.But, because there are some problems in its driving device at aspects such as safe and reliable, economy and durability.Therefore, still can not be widely adopted at home.

The purpose of this utility model is to provide a kind of New Flap Rudder Gear, and this apparatus structure is reasonable in design, and is safe and reliable, economical and practical.

A kind of New Flap Rudder Gear, form by main rudder, rudder stock, following hinge, wing flap, upper hinge and wing flap transmission device, main rudder makes it be connected with hull by rudder stock, wing flap makes it be connected with main rudder by upper hinge with following hinge, a parts solid welding of flap transmission device is at the top of wing flap, and another parts and the solid welding supporting base in hull is hinged.Described wing flap transmission device can be guide rod type, chute-type, hinge type or oscillating rod type.Guide rod type wing flap formula transmission device is made up of guide rod, guide rod sleeve and supporting base, and the solid welding of guide rod sleeve is at the top of wing flap, and guide rod inserts in the leader casing, is hinged with the supporting base of solid welding in hull.

The guide rod type that the utility model provides, chute-type, hinge type and four kinds of New Flap Rudder Gears of oscillating rod type, having simple in structure, safe and reliable, long service life, advantage such as easy to maintenance, is that various boats and ships are provided with the essential good driving device that is equipped with of flap.

The utlity model has following accompanying drawing:

Fig. 1. guide rod type Flapped rudder transmission device scheme drawing;

Fig. 2. chute-type Flapped rudder transmission device scheme drawing;

Fig. 3. hinge type Flapped rudder transmission device scheme drawing;

Fig. 4. oscillating rod type Flapped rudder transmission device scheme drawing.

Below in conjunction with drawings and Examples the utility model is described in detail:

As shown in Figure 1, novel guide rod Flapped rudder transmission device is made up of main rudder 1, rudder stock 2, following hinge 3, wing flap 4, upper hinge 5, guide rod 6, guide rod sleeve 7 and supporting base 8.Wherein main rudder 1 makes it be connected with hull by rudder stock 2; Wing flap 4 makes it be connected with main rudder 1 by upper hinge 5 and following hinge 3; 7 solid weldings of guide rod sleeve are at the top of wing flap 4; Guide rod 6 inserts in the guide rod sleeve 7, and hinged with the supporting base 8 of solid welding in hull.Its principle of work is that under the drive of upper and lower hinge, wing flap also rotates the α angle when rudder stock drives main rudder rotation α angle; Meanwhile, because the directional tagging of guide rod sleeve, guide rod can rotate the β angle again around supporting base.Therefore, main rudder rotates the α angle, and wing flap has rotated the alpha+beta angle, make the steering wheel wing section (camber is zero) of original symmetry, become the wing profile of asymmetric band camber, the effect of wing flap forces current to change and flows to, improve lift, increase moment of turning ship, improve boats and ships and maneuvering performance.

As shown in Figure 2, novel chute-type Flapped rudder transmission device: form by main rudder 1, rudder stock 2, following hinge 3, wing flap 4, upper hinge 5, slide block 6, chute 7 and supporting base 8.Being connected of rudder stock, main rudder and wing flap identical with guide rod type (following other several patterns are also identical), slide block 6 solid weldings are at the top of wing flap 4; Chute 7 tips upside down on the slide block 6, and hinged with the supporting base 8 of solid welding in hull.Its principle of work basic identical with guide rod type (following other several patterns are identical), what play the guiding role is slide block, makes chute rotate the β angle around supporting base, promptly when main rudder rotated the α angle, wing flap had rotated the alpha+beta angle.

As shown in Figure 3, new hinges formula Flapped rudder transmission device: by main rudder 1, rudder stock 2, down hinge 3, wing flap 4, upper hinge 5, hinge pay 6 and supporting base 8 form.It is hinged that wherein hinge is paid 6 an end and wing flap 4 tops, and the other end and the solid welding supporting base in hull is hinged.Its principle of work is to rotate with main rudder when wing flap, drives hinge and pays around supporting base rotation β angle, and promptly wing flap has rotated the alpha+beta angle.

As shown in Figure 4, novel oscillating rod type Flapped rudder transmission device: form with supporting base 8 by main rudder 1, rudder stock 2, following hinge 3, wing flap 4, upper hinge 5, fork 6, connecting rod 7.Wherein fork 6 is fixed on the top of wing flap; Connecting rod 7 is hinged with fork 6, and the other end and the solid welding supporting base in hull is hinged.Its principle of work is, when wing flap rotates with main rudder because the angle that fork and connecting rod constituted changes, cause fork around about hinge axis β angle, promptly wing flap has rotated the alpha+beta angle.

Four kinds of New Flap Rudder Gears are because structural shape has been done can not cause fault because of fishing net, over-water floats than improving.Turning cylinder adopts the stainless steel material, have simple in structure, intensity is high, not fragile, use advantages such as reliable.
