Embodiment
Below according to drawings and examples, the present invention is further described.
As shown in Figures 1 to 6, a kind of unidirectional limiter helical structure, described unidirectional limiter helical structure include outer cone machine
Structure 1 and inner conical drogue 2；As shown in Figure 3 and Figure 4, described outer cone mechanism 1 is cylindrical structural, and the axle center of outer cone mechanism 1 is provided with band
Tapered centre bore 1-1, is uniformly provided with some through holes on the outer marginal circumference of outer cone mechanism 1, external device (ED) by through hole with it is outer
Cone mechanism 1 is connected, that is, realizes the drive connection of external device (ED) and leading screw 3；As shown in Fig. 5 Fig. 6, outside described inner conical drogue 2
The centre bore 1-1 of the structure of circumference and outer cone mechanism 1 matches, and the axially extending bore of inner conical drogue 2 is provided with what is matched with leading screw 3
Helicla flute 2-1；As depicted in figs. 1 and 2, described outer cone mechanism 1 is sleeved on leading screw 3 by inner conical drogue 2, and when mounted,
Ensure that outer cone mechanism 1 can not slide from inner conical drogue 2, i.e. outer cone mechanism 1 and the external device (ED) that is connected with outer cone mechanism 1
Weight acts on inner conical drogue 2 all the time；The outside of described outer cone mechanism 1 is uniformly provided with some screwed hole 1-2, and screw 4 is worn
Cross described screwed hole 1-2 and the guide groove 2-2 in the outside of inner conical drogue 2 coordinates, described guide groove 2-2 one end is closed one end and opened
Mouthful, described guide groove 2-2 openend is located at the less one end of excircle diameter of inner conical drogue 2, and the screw 4 of setting limits outside
The relative rotation between mechanism 1 and inner conical drogue 2 is bored, meanwhile, only need to be by screw 4 when needing leading screw 3 and external device (ED) being separated
Slided along the guide groove 2-2 of inner conical drogue 2 to guide groove 2-2 openend and be achieved that outer cone mechanism 1 and point of inner conical drogue 2
From realizing the separation of leading screw 3 and external device (ED).
As the preferred of the present embodiment, described taper is Morse taper, and Morse's taper is the international standard of a taper,
For stationary fit to be accurately positioned.Due to taper very little, using the principle of frictional force, certain moment of torsion can be transmitted, and because
It is taper fit, it is possible to convenient dismounting.In the certain limit of same taper, part be free to dismount, simultaneously
Using effect is not interfered with again at work.
As the improvement of the present embodiment, as shown in Fig. 2 the screw rod end of described screw 4 is the cylindrical structure of non-threaded,
The screw rod end of described screw 4 is designed to the cylindrical structure of non-threaded, is helicitic texture relative to screw rod end, non-threaded
Cylindrical structure increase screw 4 and inner conical drogue 2 guide groove 2-2 contact area so that lifting surface area becomes big, acts on
Stress on screw 4 correspondingly reduces.
As the improvement of the present embodiment, described inner conical drogue 2 is made up of the 2-3 of half tapered sleeve I and the 2-4 of half tapered sleeve II, half tapered sleeve I
2-3 and the 2-4 of half tapered sleeve II are adapted, when inner conical drogue 2 occur abrasion need change when, screw 4 is unscrewed, the 2-3 of half tapered sleeve I with
The 2-4 of half tapered sleeve II is released, then the new 2-3 of the half tapered sleeve I and 2-4 of half tapered sleeve II installations are entered, then tightens screw 4.
The present invention, which first first covers outer cone mechanism, to be attached on leading screw, and half tapered sleeve I and half tapered sleeve II are then fitted in into silk respectively
The side of thick stick, the less one end of inner conical drogue excircle diameter one end larger with the center-hole diameter of outer cone mechanism is staggered relatively,
Then outer cone mechanism is slided into inner conical drogue, until inner conical drogue is locked in the centre bore of outer cone mechanism, and Yao Shi outer cones mechanism
On screwed hole guide groove corresponding with inner conical drogue match, use screw to cause screw through the screwed hole in outer cone mechanism
Screw rod end insertion inner conical drogue on guide groove in, screw limits the relative rotation of outer cone mechanism and inner cone inner room, meanwhile,
When needing leading screw and executing agency being separated, guide groove of the screw along inner conical drogue need to only be slided to the openend of guide groove
The dynamic separation for being achieved that outer cone mechanism and inner conical drogue, that is, realize the separation of leading screw and executing agency.
For horizontally disposed leading screw, outer cone mechanism is mutually matched installation with inner conical drogue；For vertically disposed silk
Thick stick, outer cone mechanism should be arranged on the top of inner conical drogue；For the leading screw being obliquely installed, outer cone mechanism can be located at the oblique of inner conical drogue
Top, outer cone mechanism can also be located at the obliquely downward of inner conical drogue in the range of certain angle, and this angular range is by by outside
Bore the gravity of mechanism and external device (ED) and take into account the factors such as moment of torsion, frictional force and be calculated.
