Further, the link mechanism includes connecting rod and connecting rod cap；

Described connecting rod one end is equipped with circular rings, and the other end is equipped with the rectangular block to match with connecting rod cap；

Described II one end of fixing axle is equipped with u shaped connector, and u shaped connector is connected with the circular rings of connecting rod by pin, the other end Rectangular block in the middle part of be equipped with semi arch, be equipped with semi arch in the middle part of the connecting rod cap, the rectangular block and connecting rod cap of connecting rod are relatively fixed, To which the axle journal of crank rudder is fixed between rectangular block and connecting rod cap.

Further, the fixing axle II is threadedly coupled with gear ring.

Further, it is respectively equipped with threaded hole on the rectangular block and connecting rod cap of the connecting rod, rectangular block and connecting rod cap pass through Bolt fastening.

Further, the driver pinion gear teeth only have 4, and complete pinion gear should have 22 teeth, modulus 0.4, pressure 20 ° of power angle.

Further, the axial line distance between the connecting rod two end mounting hole is 21.5mm, connecting rod rectangular block semi arch Center line and crank rudder main-shaft axis distance are 8mm, and crank rudder main-shaft axis intersects with II axis of fixing axle.

Further, the gear ring is at middle position, II u shaped connector axially bored line of fixing axle away from crank rudder main-shaft axis away from From for 19.96mm, when gear ring moves to limit on the left position, crank rudder deflects 16.25 ° counterclockwise, moves to limit on the right-right-hand limit position When, crank rudder deflects 18.35 ° clockwise.

Further, the direct current generator axis is parallel with crank rudder main-shaft axis, the crank arm and rudder of the crank rudder Plate plane is vertical.

Further, the other end arc section of the gear ring is threaded with fixing axle I, the fixing axle I and fixing axle II is symmetrical.

Compared with prior art, the present invention its remarkable advantage is:

1) direct current generator does continuously unidirectional rotation, and crank rudder does interval, between positive and negative maximum angle of rudder reflection, limit Period deflection；The displacement of gear ring very little can cause the biggish angular movement of crank rudder；

2) revolving speed that need to only control direct current generator is reduced without controlling the steering of direct current generator to motor performance itself Requirement, and motor control a pair of rudder piece, to reduce cost.

3) by calculating and adjusting the number of teeth, modulus or the connecting rod of driver pinion and gear ring, fixing axle 2, the length of crank arm Degree can change the maximum angle of the positive and negative deflection of crank rudder in a big way.

Specific embodiment

Present invention is further described in detail with reference to the accompanying drawing.

As shown in figs. 1-12, a kind of Correction Projectiles steering engine transmission mechanism, including fixing axle I 1, driver pinion 2, gear ring 3, fixing axle II 4, connecting rod 5, direct current generator 6, connecting rod cap 7, crank rudder 8.

Driver pinion 2 is fixedly mounted on 6 output shaft of direct current generator；Driver pinion 2 is partial gear, actively small tooth 2 axis are taken turns in the plane of symmetry of gear ring 3 and are intersected in two fixing axle axis, and the only tooth engagement with 3 side of gear ring；3 liang of gear ring End is respectively provided with a fixing axle installation threaded hole, for installing fixing axle I 1 and fixing axle II 4；There is U-shaped connect in II 4 one end of fixing axle Head is connect with the round one end of connecting rod 5 by pin；The rectangular one end of connecting rod 5 connect to form axis with connecting rod cap 7 by two stove bolts Neck mounting hole, bore dia is equal with crank rudder [8] rod journal diameter and forms cooperation.Fixing axle I 1 and fixing axle II 4 can only Make axial translational movement.

As shown in figure 3,2 gear teeth of driver pinion only have 4, complete pinion gear should have 22 teeth, modulus 0.4, pressure 20 ° of angle.

As shown in figure 4, each 11 tooth of about 3 gear ring, is engaged with driver pinion 2.3 both ends of gear ring are respectively by one The threaded hole of M3X0.5.Side-to-side movement critical distance is 2.37mm.

The fixing axle II 4 is connect with connecting rod 5, and 5 liang of mounting hole axis distances of connecting rod are 21.5mm, connecting rod 5 and crank rudder 8 Connection, 5 square end of connecting rod, half centerline hole and 8 main-shaft axis of crank rudder distance are 8mm.And 8 main-shaft axis of crank rudder and fixation The intersection of II 4 axis of axis.

Gear ring 3 is at middle position, i.e., as shown in Figure 10, II 4U type joint axially bored line of fixing axle is away from 8 spindle shaft of crank rudder Linear distance is 19.96mm.When gear ring 8 moves to limit on the left position, 16.25 ° of the deflection counterclockwise of crank rudder 8 moves to right pole When extreme position, 18.35 ° of the deflection clockwise of crank rudder 8.

6 axis of direct current generator is parallel with 8 main-shaft axis of crank rudder.8 crank arm of crank rudder is vertical with rudder plate plane.

Transmission mechanism provided by the invention applied to steering engine, the mechanism is using gear ring by continuously unidirectional turn of direct current generator Turn is changed to the translation of fixing axle, and then fixing axle pushes the connecting rod being connected with crank rudder, and the translation of fixing axle is converted to song Handle rudder interval, between positive and negative maximum angle of rudder reflection, limit period deflection.Transmission mechanism of the invention need to only control electricity The period deflection of rudder piece can be realized without controlling motor steering in the revolving speed of machine.
