Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific implementation mode of the present invention.In the description of the steering engine with overload protection of the present invention, it is to be understood that " preceding ",
The terms such as " rear ", "upper", "lower", " front ", " back side " are merely for convenience of description technical scheme of the present invention, rather than indicate
Signified device or element must have a particular orientation, therefore be not considered as limiting the invention.
As described in Fig. 1-2 4, the steering engine with overload protection in a preferred embodiment of the invention, including 1 He of shell
Driving device 2 further includes the overload protection arrangement 3 set within the case 1；
Overload protection arrangement 3 includes：
First rotating shaft 30；
First gear 31 is located in first rotating shaft 30, including first end face, is equipped with around first rotating shaft 30 in first end face
The first connecting portion 310 of axial symmetry distribution；
Second gear 32 is axially displaceably located in first rotating shaft 30, includes the second end face opposite with first end face,
The second connecting portion 320 coordinated with first connecting portion 310 being distributed around 30 axial symmetry of first rotating shaft is equipped in second end face；
And elastic component 33, it is located in first rotating shaft 30, acts axially on second gear 32, for overload protection arrangement 3
The linkage status of first connecting portion 310 and 320 mutual male-female engagement of second connecting portion under the elastic reaction in elastic component 33,
Or overcome the elastic reaction of elastic component 33 in second gear 32 and first connecting portion 310 is detached with second connecting portion 320
Discrete state；Wherein, elastic component 33 can usually select spring；
First gear 31 or second gear 32 are driven by driving device 2.
When using the steering engine, it can be joined with first gear 31 and the external load device for controlling rudder for ship or aircraft rudder surface
It is dynamic, to which driving device 2 drives second gear 32 and then first gear 31, final band dynamic load is driven to rotate.As Fig. 6-12 institute
Show, when the first, second protrusion 310,320 matches the torsion between shaft less than predetermined force F, in the axis of elastic component 33
Under being acted on to elastic force, second connecting portion 320 is kept and the cooperation of first connecting portion 310, first gear 31 and second gear 32 and tooth
Wheel shaft rotates synchronously the driving device 2 that the connection of second gear 32 provides torsion, and first gear 31 is connect with load device, to have
It imitates and the torsion of driving device 2 is reliably passed to the load device for controlling rudder for ship or aircraft rudder surface；As shown in figure 17,
When the first, second protrusion 310,320 matches the torsion between shaft more than predetermined force F, second gear 32 overcomes bullet
Property part 33 elastic force, first connecting portion 310 and second connecting portion 320 misplace and detach, first gear 31 with second gear 32 not
Link again, to be effectively protected gear assembly, prevent gear field of conjugate kill in addition the flank of tooth damage, extend gear set
The service life of part.
In order to enable first gear 31 and second gear 32 stable delivery torsion but also can be smoothly detached from overload
Linkage, first connecting portion 310 and second connecting portion 320 are preferably radial, and the side wall 310a of first connecting portion 310 is in the first tooth
It is oblique in the circumferential direction of wheel 31, since second connecting portion 320 is matched with first connecting portion 310, so the second protrusion
The side wall 320a in portion 320 is also oblique in the circumferential direction of second gear 32, setting skewed in this way so that external loading mistake
When load, axial component is generated so that first gear 31 can smoothly overcome the elastic reaction of elastic component 33 with second gear 32,
It relatively rotates.
Further include the baffle ring 34 being located in first rotating shaft 30, elastic component 33 to dispose elastic component 33, overload protection arrangement 3
Spring is selected, for spring pocket in shaft, both ends are respectively held against baffle ring 34 and second gear 32, to act axially on second gear
32.Overload protection arrangement can also include the washer 35 for being located at 33 both ends of elastic component, to avoid gear surface by spring or baffle ring
34 damage by pressure.
In existing steering engine, lead is to guide to control panel from steering engine side, and such disadvantage is the increase in complicated
It is exactly that lead easily snaps off that degree, which also has, and in order to overcome the disadvantage, steering engine of the invention may include the second shaft 4 and be located at the
The third gear 5 to link in two shafts 4 and with first gear 31, the both ends of the second shaft 4 are exposed outside to the shell 1, and second
Shaft 4 is equipped with the fairlead 41 axially penetrated through, to which the second shaft 4 is hollow shaft.The lead of steering engine and other control sections
Lead can be drawn by fairlead 41 (i.e. hollow mandrel interior), lead simple in structure so is not allowed easily broken yet.
Further, wire lead slot 42 is also provided on the side wall of the second shaft 4, wire lead slot 42 is connected to the second shaft 4
External and fairlead 41, and opened to the end face of shaft, fairlead 41 and wire lead slot 42 are used to arrange power control line, to
It can be very good to hide power control line, prevent power control line from winding, be effectively protected power control line, reduce loss,
Extend the service life of power control line.
It, can be with outside for controlling rudder for ship or aircraft rudder while in order to arrange power control line in the second shaft 4
The load device in face connects, and the end face of the second shaft 4 is equipped with the connecting hole 43 around fairlead 41, and external loading device can be with
Equipped with flange, it is connect with connecting hole 43 by flange.
Driving device 2 includes motor 21, the transmission gear 22 driven by motor 21 and engaged with second gear 32 the
Four gears 6, transmission gear 22 and the 4th gear 6 engage successively, to drive the rotation of the second shaft 4 by motor 21；As Fig. 9,
Shown in 10, motor 21, transmission gear 22, the 4th gear 6 and overload protection arrangement 3 surround the second shaft 4 and are arranged successively so that horse
Up to the setting of 21, transmission gear 22, the 4th gear 6, overload protection arrangement 3 and the second shaft 4 in fan-shaped distribution.
The wall thickness of second shaft 4 is 0.05 to 0.15 times of diameter, such as a diameter of 26.86mm, thickness be 2.47mm such as
Shown in Figure 24, x is the wall thickness of the second shaft 4, and thicker wall thickness can enhance the intensity of the second shaft 4, reduce the risk of fracture,
For example, according to experiment, wall thickness 1.5mm increases to 2.47mm, and intensity can improve 60% or so；Wall thickness within the above range, both
It ensures that the second shaft 4 has enough intensity, also ensures that fairlead 41 has enough sizes in order to cabling.In addition, second turn
It, will not be with other knots after connecting hole 41 is connect with exterior part outside that one end protrusion shell 1 equipped with connecting hole 41 of axis 4
Structure generates collision or friction.
Preferably, driving device 2 includes the 4th gear 6 engaged with second gear 32, and the thickness of the 4th gear 6 is more than the
The thickness of two gears 32 engages with the holding of the 4th gear 6 when being axially moved for second gear 32, and then makes first connecting portion
310 detach with second connecting portion 320.
In conclusion the steering engine of the present invention passes through first gear 31, second gear 32 due to being equipped with overload protection arrangement 3
Overload protection is realized with the correlation of elastic component 33, so can use efficiently and securely be passed to the torsion of driving device 2
In control rudder for ship or the load device of aircraft rudder surface, and it can be effectively protected gear assembly in overload, prevent gear from engaging
Face is killed or even flank of tooth damage.
