Abstract

The utility model discloses a crosshead actuating device of a flap rudder, which relates to the technical field of the actuating device of a flap rudder of a high lift rudder and solves the technical problem of the actuation of a flap rudder. The crosshead actuating device comprises a main rudder which is fixedly arranged on a rudder carrier. The utility model is characterized in that the crosshead actuating device also comprises a cross head whose vertical component is a vertical axle which is pivotally arranged on one side of the rudder rod which is near the flap rudder, the rudder rod is arranged on the central line of the position of a positive rudder of the main rudder, the distance from the shaft line of the crosshead vertical shaft to the shaft line of the rudder rod is less than the distance form the shaft line of the flap rudder to the shaft line of the rudder rod, wherein a horizontal component of the crosshead is a guiding component which is provided with a guiding rod capable of gliding, the rear end of the guiding rod is fixed on the top of the flap rudder. The utility model has the advantages of excellent durability, simple structure, safety, availability, and convenient assembly, disassembly, and maintenance, which can improve the beneficial effects of the rudder.

Description

The crosshead driving device of flap

Technical field

The utility model relates to the Marine engineering technology, particularly relates to a kind of driving device technology of high lift rudder flap.

Background technology

Boats and ships use common conventional rudder at present, and steerage is poor, rudder area big (when identical steerage), and rudder blade is heavy, causes the boats and ships rolled steel dosage to increase, and appendage drag increases.

Though flap since generation, has had several different wing flap type of drive, all has various shortcomings.As gear type transmission: complex structure, wearing and tearing are big.General guide rod type: poor, insecure, fragile with hull bearing structural strength, the guide rod exposed junction breaks easily.

The utility model content

At the defective that exists in the above-mentioned prior art, it is good that technical problem to be solved in the utility model provides a kind of durability, simple in structure, safe and reliable, be connected firmly, be convenient to install, dismantle, keep in repair, can make the corner of the corner of flap, thereby improve the crosshead driving device of the flap of steerage greater than main rudder.

In order to solve the problems of the technologies described above, the crosshead driving device of a kind of flap provided by the utility model comprises:

One main rudder is installed with rudder stock;

One flap, the trailing edge of the main rudder that is rotationally connected;

One rudder bearer, rudder stock are pivoted (axle connects) in rudder bearer;

One support is fixedly arranged on rudder bearer;

It is characterized in that, also comprise crosshead, (vertically) of described crosshead, perpendicular part was a vertical pivot, the crosshead vertical pivot is pivoted (axle connect) rudder stock on the center line of the main rudder amidship position (level) of support by a side of flap, and (vertical) axis of being rotationally connected less than flap and main rudder of crosshead vertical pivot axis to the distance of rudder stock (vertically) axis is to the distance of rudder stock (vertical) axis; (level) cross member of described crosshead is a guidance set, in establish slidably guide rod, the top of flap is fixed in the rear end of described guide rod; When main rudder rotates and drives flap and rotates together, make the corner of the corner of flap, thereby improve steerage or reduce rudder stock moment greater than main rudder.

Further, described guidance set is a guide pipe.

Further, described guidance set is an orienting lug.

Utilize the crosshead driving device of the flap that the utility model provides, because the rotation of adopting flap is with the structure around crosshead vertical pivot rotational, safe and reliable, be connected firmly, make when main rudder rotates and drives flap and rotates together, make the corner of the corner of flap, thereby improve steerage or reduce rudder stock moment greater than main rudder; Because the stationkeeping of guide rod on flap, the scope of stretching in the rudder body outward is little, does not break so guide rod is easy to wear.Therefore the utlity model has simple in structurely, be convenient to the characteristics of installing, dismantle, keeping in repair, be suitable for various types of boats and ships and use.

Description of drawings

Fig. 1 is the structural representation of the crosshead driving device of the utility model embodiment flap;

Fig. 2 is the transmission principle figure of the crosshead driving device of the utility model embodiment flap.

The specific embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.

Referring to Fig. 1, shown in Figure 2, the crosshead driving device of a kind of flap that the utility model embodiment is provided comprises a main rudder 1, is installed with rudder stock 11; One flap 2, the trailing edge of the main rudder 1 that is rotationally connected; One rudder bearer 4, rudder stock 11 are pivoted (being rotationally connected) in described rudder bearer 4; One support 5 is fixedly arranged on rudder bearer 4; It is characterized in that, also comprise " ten " prefix 3 of forming by the perpendicular part (1) of (level) cross member () and (vertical), (vertically) of described crosshead 3, perpendicular part was a vertical pivot 33, crosshead vertical pivot 33 is pivoted (being rotationally connected) rudder stock 11 on the center line Q of the main rudder amidship position (level) of support 5 by a side of flap 2, and crosshead vertical pivot axis Y to (vertical) axis X that is rotationally connected less than flap and main rudder apart from N of rudder stock (vertically) axis Z to rudder stock (vertical) axis Z apart from M; (level) cross member of described crosshead is a guidance set 32, in establish slidably guide rod 31, the top of flap 2 is fixed in the rear end of described guide rod 31.

As shown in Figure 2, when main rudder 1 rotates, can drive the flap 2 that is rotationally connected with the main rudder trailing edge rotates, again because described guide rod 31 is fixed in flap 2, and guide rod 31 can only be in the guidance set 32 of crosshead (level) slide and the guidance set that drives crosshead rotates around crosshead vertical pivot axis Y (level), so main rudder 1 ' after rotating, drive its rear end axle X ' bonded assembly flap, and guide rod 31 ' makes flap 2 ' rotate around crosshead 3 ' vertical pivot axis Y, make the corner r of flap when coming about can be, thereby improve steerage or reduce rudder stock moment greater than the corner R of main rudder.The utility model embodiment cross-head guide assembly is an orienting lug, and by two powerful otic placodes and hull bolted connection, installs and change convenience, and the lining (synthetic material) in it is convenient to periodic replacement and dissembling inspection (do not lie up and get final product).

The utility model embodiment cross-head guide assembly also can be a guide pipe.
