Description
Technical field
The utility model relates to universal machine technical field, particularly a kind of axle connect with wheel hub without key swelling linkage structure.
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 wheel 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 wheel hub 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 wheel hub, and too emphasize to ensure that the mechanical strength of axle and wheel hub 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 wheel hub.
Existing expansion sleeve linkage structure, normally in inner sleeve upper shed, makes opening shrink by extruding, thus with axle obvolvent, but the fitting surface of inner sleeve and overcoat is subject to shedding deformation impact, its area of contact diminishes, and easily occurs locking phenomenon loosely.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of coupling reliability is high, the axle of easy accessibility and locking uniform force connects with wheel hub without key swelling linkage structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of axle connect with wheel hub without key swelling linkage structure, comprise inner conical drogue, external conical sleeve, wheel hub, locking element and main shaft, inner conical drogue offers opening along its radial direction, inner conical drogue along its axial direction offer can main shaft coordinate inner conical drogue through hole, the side of inner conical drogue is provided with conical surface A; External conical sleeve offers external conical sleeve through hole along its axial direction, and the outer side wall of external conical sleeve and the sidewall of external conical sleeve through hole are respectively arranged with conical surface B and conical surface C; Wheel hub offers wheel hub through hole along its axial direction, the sidewall of wheel hub through hole is provided with conical surface D, during assembling, main shaft is arranged in inner conical drogue through hole, conical surface A coordinates with conical surface B, conical surface C coordinates with conical surface D, and inner conical drogue is connected by locking element locking with external conical sleeve, and the outer rim end face top of inner conical drogue is pressed on the side of wheel hub.
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 inner conical drogue through hole, unthreaded hole is slotted hole structure, inner conical drogue offers multiple tapped hole, multiple tapped hole is positioned at circumferentially same, and coaxial with external conical sleeve through hole, single-head screw through unthreaded hole, and is connected by screw-thread fit with tapped hole.
The tapering of described conical surface A is more than or equal to the tapering of conical surface B.
The tapering of described conical surface C equals the tapering of conical surface D.
The utility model has the following advantages:
1, the utility model need not spline on axle and wheel hub, the mechanical strength of axle and wheel hub 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, also wedge-like engagement is adopted again by tapered sleeve and wheel hub, 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 conical surface A is more than or equal to the tapering of conical surface B, when coupling shaft and wheel hub, in locking process, the internal diameter of inner conical drogue reduces gradually, the tapering of conical surface A is also reduced gradually, when locked, the tapering of conical surface A is consistent with the tapering of conical surface B, thus increase conical surface A in the locked condition and conical surface B coordinate area, thus make that the locking of axle is stressed more evenly, firmly, linking intensity is high.
3, the utility model only needs can realize two pairs of fitting surface lockings by locking locking element, and locking element adopts symmetrical structure, and its coupling reliability is high.
