Description
Technical field
The utility model relates to universal machine technical field, particularly a kind of axle be connected with axle without key swelling connection set.
Background technique
In common mechanical transmission, axle and the wheel (such as belt pulley, gear, sprocket wheel etc.) be enclosed within axle are all be fixed together by key, realize the object transmitted motion and produce torsion.Due to traditional key connecting dismounting inconvenience, usually handling coupling be all adopt manually beat, the mode of mechanical press mounting carries out, therefore troublesome poeration, and it is time-consuming to require great effort.In addition, the structure that axle is connected with axle often needs the occasion being applied in applicable heavy load.If in order to ensure that producing enough torsion makes the scale of construction of key excessive, then can affect the mechanical strength of axle, and too emphasize to ensure that the mechanical strength of axle will make key be easy to very much damage.So, how to take into account can ensure abundant exercise transmit have again enough torsion, be the technical barrier that axle is connected with axle.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provide a kind of easy accessibility, linking intensity high with locking uniform force axle be connected with axle without key swelling connection set.
The purpose of this utility model is achieved through the following technical solutions: a kind of axle be connected with axle without key swelling connection set, comprise inner conical drogue, external conical sleeve and locking element, inner conical drogue is provided with the through hole A that can coordinate with axle A and axle B along its axial direction, inner conical drogue has opening along its radial direction, the outer side wall of inner conical drogue is provided with male cone (strobilus masculinus), external conical sleeve is provided with through hole B along its axial direction, the madial wall of through hole B is provided with inner conical surface, during assembling, male cone (strobilus masculinus) and inner conical surface are connected, and are fixedly connected with external conical sleeve by inner conical drogue by locking element.
Described locking element is single-head screw, inner conical drogue offers multiple unthreaded hole, multiple unthreaded hole is positioned at circumferentially same, and coaxial with through hole A, unthreaded hole is slotted hole structure, inner conical drogue offers multiple tapped hole, multiple tapped hole is positioned at circumferentially same, and coaxial with through hole B, single-head screw through unthreaded hole, and is connected by screw-thread fit with tapped hole.
The tapering of described male cone (strobilus masculinus) is more than or equal to the tapering of inner conical surface.
The utility model has the following advantages:
1, the utility model need not spline on axle and coupling, the mechanical strength of axle and coupling can not be damaged, but adopt conical surface locking, frictional force carry-over moment after being reduced by the through hole of tapered sleeve and between axle, thus make the through-hole diameter that only need control tapered sleeve when dismounting just can realize fast assembling-disassembling, easy accessibility.
2, the tapering of male cone (strobilus masculinus) is more than or equal to the tapering of inner conical surface, when coupling shaft A and axle B, in locking process, the internal diameter of inner conical drogue reduces gradually, the tapering of male cone (strobilus masculinus) is also reduced gradually, when locked, the tapering of male cone (strobilus masculinus) is just consistent with the tapering of inner conical surface, thus increase male cone (strobilus masculinus) in the locked condition and inner conical surface coordinate area, thus make that the locking of axle is stressed more evenly, firmly, linking intensity is high.
