Abstract
The invention discloses a synchronously opening device used for a guided cartridge rudder sheet. The synchronously opening device is mainly applied to the longitudinal folded rudder sheet, arranged in an X type, of a guided cartridge and is composed of four sets of restraint mechanisms. Every restraint mechanism comprises incomplete bevel gears, a connecting shaft, a pin and the like, wherein the incomplete bevel gears are symmetrically arranged relative to the connecting shaft and connected with the connecting shaft through the pin. The incomplete bevel gears on the two sides of every restraint mechanism are matched with the incomplete bevel gears of the restraint mechanisms on the two adjacent sides, all the matched incomplete bevel gears are in a meshed state in the closing and opening processes of the rudder sheet, the mutually meshed bevel gears break away after complete opening, and the restraint mechanisms are independent mutually.
Description
Technical field
The invention belongs to guided cartridge technical field, the X-type that relates generally to a kind of guided cartridge is arranged the synchronous deploying device of rudder sheet.
Background technology
Guided cartridge need to be launched with weapons with pipes, before transmitting, is first loaded in barrel, and the internal diameter of barrel coordinates and positions with the profile of guided cartridge.The rudder sheet of guided cartridge arranges along shell axis circle distribution, for reaching above-mentioned requirements, need before transmitting, carry out that rudder sheet is folding to be folded, guided cartridge goes out after barrel, according to predetermined instant, open rudder sheet again, after opening, by controlling the rotation of rudder sheet, realize the guidance function of shell.The principle of opening adopting at present is mostly that this rudder sheet of independent power drive by each rudder sheet oneself opens, and four rudder sheets work alone.This principle has two problems:
Each rudder sheet to open power different with drag size, rudder sheet is not constraint mutually in the process of opening, so the synchronism that rudder sheet opens is poor, opens moment and easily shell flight attitude is caused to larger impact.
2. when certain rudder sheet process of opening runs into larger resistance, the power of its excess-three rudder sheet cannot provide support to it, opens reliability poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of synchronous deploying device of arranging longitudinal folding rudder sheet for guided cartridge X-type, can improve synchronism and reliability that rudder sheet opens.
The technical solution adopted for the present invention to solve the technical problems is: utilize two incomplete bevel gears and a connecting axle to connect to form a set of constraint mechanism by two connecting pins, quadruplet constraint mechanism forms whole deploying device by rectangular arrangement, four rudder sheets are arranged on each constraint mechanism by connecting pin, form an integral body with deploying device.Rudder sheet is from folding in the process of opening, the constraint of working in coordination of the incomplete bevel gears of the incomplete bevel gear in every cover constraint mechanism and adjacent two cover constraint mechanisms, guarantee that four rudder sheets open synchronously, after opening, not exclusively bevel gear departs from mutually, four rudder sheets are relatively independent, non-interference.
Described constraint mechanism is comprised of two incomplete bevel gears and a connecting axle and two connecting pins.
Described incomplete bevel gear is cylindrical shape, and one end is to have the incomplete bevel gear of 1/4 circle, and the other end is the cylinder that connecting axle is installed.
Beneficial effect of the present invention embodies in the following areas:
The present invention has increased the mutual constraint of rudder sheet in rudder sheet opens process, can guarantee the synchronism that four rudder sheets open, be conducive to the stable of shell flight attitude, and when certain rudder sheet is opening while running into the resistance that self cannot overcome in process, its excess-three rudder sheet can provide power support to it by this device, the reliability of opening to improve rudder sheet.

The specific embodiment
The present invention relates to the synchronous deploying device of a kind of rudder sheet, be mainly applicable to the longitudinal folding rudder sheet that guided cartridge X-type is arranged.This synchronous deploying device is comprised of quadruplet constraint mechanism, and every cover constraint mechanism comprises incomplete bevel gear, connecting axle, pin etc., and not exclusively bevel gear is arranged symmetrically with respect to connecting axle, by pin, is connected with connecting axle.Constraint mechanism matches with the incomplete bevel gear of adjacent both sides constraint mechanism respectively by the incomplete bevel gear of both sides, rudder sheet fold and the process of opening in, the incomplete bevel gear of all pairings is all in engagement, after opening completely, intermeshing bevel gear departs from, and constraint mechanism is independent separately.
Have particular application as: quadruplet constraint mechanism and four rudder sheets are connected, by constraint mechanism, guarantee four rudder sheets open often in a flash, rudder sheet opening angle is all consistent, contiguous while opening completely, not exclusively bevel gear departs from.Quadruplet rudder sheet is transformed into the state of working alone.This device is by the work characteristics of incomplete bevel gear, four rudder sheets are being folded to the stage, opening process stage in state constrained each other, the synchronism of process is opened in assurance, improve the reliability of opening action, opening the stage completely, rudder sheet, in separate, reaches the state that can guide control.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Fig. 1 a, Fig. 1 b, Fig. 2 a, Fig. 2 b, Fig. 3, synchronous deploying device is comprised of quadruplet constraint mechanism 1, the left angular wheel 4 of constraint mechanism 1 by separately and right accurate gear 6 respectively with left angular wheel 4 and right accurate gear 6 cooperatings of adjacent two cover constraint mechanisms 1.Constraint mechanism 1 comprises: left angular wheel 4, two connecting pins 3, connecting axle 5, right bevel gear 6.Left angular wheel 4 and right bevel gear 6 be one end with the incomplete bevel gear of cylindrical bump, on left angular wheel 4, right bevel gear 6, have the installing hole of connecting pin 3, connecting pin 3 and connecting axle 5 are cylindric, have the installing hole of connecting pin 3 on connecting axle 5.Left angular wheel 4, connecting axle 5, right bevel gear 6, be fixed into an integral body by two connecting pins 3.
The present invention is connected with rudder sheet 2 by connecting pin 3, realizes the control of deploying device to rudder sheet 2.Under rudder sheet 2 folds, four left angular wheels 4 and four right bevel gears 6, all in engagement, retrain by mutual engagement, form closed loop whole, and in the process of opening at rudder sheet 2, left angular wheel 4 is identical with engagement and collapse state between right bevel gear 6.Under the complete open configuration of rudder sheet 2, four left angular wheels 4 and four right bevel gears 6, all in disengaged position, do not retrain between quadruplet constraint mechanism 1, and relatively independent, four rudder sheets 2 are also in separate state.
