Abstract
The utility model discloses a kind of wear-resisting anti-loose hubs, and including external tapered cylinder, inner barrel is equipped with hollow cylindricality via, and the periphery of cylinder is equipped with a circle triangular groove.The utility model is simple in structure, and bushing passes through for screw shaft, and does not easily cause abrasion, and the self-locking for realizing with support base by the movement of bushing when there is abrasion still can eliminate steering engine and install gap, improve measuring accuracy, ensure that measuring accuracy.
Description
Technical field
The utility model is related to arrive technical field of aerospace, a kind of wear-resisting anti-loose hub is related generally to.
Background technology
Steering engine is a kind of position（Angle）The driver of servo needs angle constantly to change and can keep suitable for those
Control system, however in traditional steering engine test installation process, due to dismounting repeatedly, its internal bushing easily generates
Abrasion, and gap may be generated after wearing, installation is caused to loosen, even result in bolt slides in bushing, so as to shadow
Ring steering engine measuring accuracy.
Utility model content
Steering engine installation gap can be eliminated the purpose of this utility model is to provide a kind of, ensures the wear-resisting locking of measuring accuracy
Bushing.
The utility model to achieve these goals, adopts the following technical scheme that：
A kind of wear-resisting anti-loose hub, including external tapered cylinder, inner barrel is equipped with hollow cylindricality via, cylinder
Periphery be equipped with one circle triangular groove.
Cylinder body portion is provided with a grooving vertically.
The cylinder body portion is equipped with hollow hole.
The cone angle of the cylinder is 50 ° -80 °.
The bushing is copper material.
The utility model is simple in structure, and bushing passes through for screw shaft, and does not easily cause abrasion, passes through lining when there is abrasion
The movement of set realizes that the self-locking with support base still can eliminate steering engine installation gap, improves measuring accuracy, ensure that test essence
Degree.

Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
Embodiment 1：Referring to Fig. 1 --- the wear-resisting anti-loose hub of one kind shown in Fig. 3, including external tapered cylinder 31,
Cylinder 31 is internally provided with hollow cylindricality via 35, and the periphery of cylinder 31 is equipped with a circle triangular groove 32.
31 body portion of cylinder is provided with a grooving 33 vertically.
The 31 body portion of cylinder is equipped with hollow hole 34.
The cone angle of the cylinder 31 is 50 ° -80 °.
The bushing is copper material.
Embodiment 2：Referring to Fig. 4 --- a kind of steering engine test mounting structure shown in Fig. 5, including steering engine fixed seat 7 and bottom
Plate 8, the both sides of bottom plate 8 are respectively equipped with left support seat 2 and right support seat 5, and steering engine fixed seat 7 is arranged between two support bases, left branch
Correspondence is respectively equipped with through hole on support seat 2 and right support seat 5, and two through hole ecto-entad is respectively installed with bushing 3,6, the head of screw rod 1
End, which sequentially passes through bushing 3,7 via of steering engine fixed seat and bushing 6 and passes through nut 4, locks.
The through hole of the left support seat 2 and right support seat 5 is bellmouth, bellmouth be internally provided with and triangular groove
32 matched protrusions 21, triangular groove 32 form the buckle structure of cylinder 31 with protrusion 21.
Especially it is to be noted that in the utility model, screw rod 1 according to the size of 7 via of steering engine fixed seat and left and right support base,
Select the axis of corresponding length and diameter, axis uses stainless steel material with high hardness, and main function is connection steering engine via and left and right
Support base；And bushing, according to the size of axis, tapered sleeve opens the effect of the similar self-locking of effect of triangular groove, passes through nut both ends
Clamping is exerted oneself, and bushing is made to be easier clamping screw axis, and in nature, screw shaft also easily propagates through bushing, does not easily cause
Abrasion in design, selects that hardness is relatively low, the preferable copper product of wearability is bushing, so can be with using the softer characteristic of copper
The abrasion of screw shaft and left and right support base is reduced, since bushing is opening taper, when there is abrasion by the movement of bushing still
Steering engine can be locked, gap will not be generated, ensures measuring accuracy.
