Abstract
The utility model relates to a fast assembly and disassembly expansion sleeve of the two-port cone ring and the open sleeve of a connecting shaft and a wheel, comprising an outer casing, wherein, a tapered ring cavity is formed at each of the two ends of the inner wall of the outer casing; two inner rings with male cones are mounted in the tapered ring cavities respectively; openings are formed on the external circumferential surfaces of the inner rings and the outer casing; a plurality of corresponding locking holes are formed on the outer casing and the ramparts of the two inner rings; the holes of one inner ring are screwed holes; the holes of the other inner ring and the outer casing are through holes; bolts are arranged in the holes; and a screwed through-hole used for disassembling is further formed on the inner ring. The expansion sleeve is arranged between a wheel hub and a shaft, during the assembly, the bolts are locked to drive the two inner ring to squeeze towards the middle part, and drive the outer casing to expand outwards so as to allow the wheel hub to be tightly expanded; and when the two inner rings shrink inwards, the shaft is compressed so that the coupling of the shaft and the wheel hub is realized. As no key slot is required to be formed on the shaft and the wheel hub, the mechanical strength of the shaft and the wheel hub is improved, and the application, the assembly and the disassembly are convenient.
Description
Technical field
The utility model relates to the link of a kind of joining shaft and wheel, especially the quick loading and unloading swelling cover of a kind of pair of opening conical ring and opening sleeve.
Background technique
In the common mechanical transmission, axle is to be fixed together by key with the wheel (for example belt pulley, gear, sprocket wheel etc.) that is enclosed within on the axle, realize the purpose of transmitting movement and moment of torsion, because there is the defective of dismounting inconvenience in traditional key connecting, the loading and unloading wheel all be adopt manually beat, the mode of mechanical press mounting carries out, it is time-consuming to require great effort, troublesome poeration.
The model utility content
The purpose of this utility model is: the quick loading and unloading swelling cover that a kind of pair of high opening conical ring of a kind of convenient disassembly, linking intensity and opening sleeve are provided.
The purpose of this utility model realizes by implementing following technical proposals Come:
The quick loading and unloading swelling cover of a kind of pair of opening conical ring and opening sleeve, it is characterized in that: comprise an overcoat, respectively there is a taper ring cavity at the two ends of outer casing inner wall, are fitted with ring in two of band male cone (strobilus masculinus) in the taper ring cavity respectively; The outer peripheral surface of ring and overcoat is provided with opening vertically in described; The ring wall of ring and overcoat are provided with corresponding a plurality of locking holes in two, and wherein the hole of an interior ring is a tapped hole, and ring is a through hole with the hole of overcoat in another, is provided with screw in the hole; Also be provided with the tapped through hole that is used to dismantle on the interior ring.
Adopt the two opening conical rings of above structure and the quick loading and unloading swelling cover of opening sleeve, its overcoat and wheel hub are close to, ring is embraced with axle in it, during assembling, with screw lock, drive two interior hoops middle part extruding, under the effect of the inner conical surface of the male cone (strobilus masculinus) of interior ring and overcoat, overcoat outwards expands, the swelling wheel hub; Shrink in two interior hoops, axial compression is tight, realized the connection of axle and wheel hub.During dismounting: lay down all screws, in the knockout screw hole of reserving of then screw being packed into, just can interior ring top is loose, then can be very light unload expansion set.Spline owing to not be used on axle and the wheel hub, the mechanical strength of axle and wheel hub improves, and uses loading and unloading very convenient.
Description of drawings
Fig. 1 is the utility model sectional view.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the stressed schematic representation of the utility model user mode.
Mark among the figure: 1 screw, 2,3 is interior ring, 4 overcoats, 5 overcoat openings, 6,7 wheel hubs, 8 removal holes, 9 locking holes.
Embodiment
As shown in Figure 1, 2, the utility model comprises an overcoat 4, and respectively there is a taper ring cavity at the two ends of outer casing inner wall, is fitted with ring (2,3) in two that are with male cone (strobilus masculinus) in the taper ring cavity at two ends respectively; Interior ring outer peripheral surface is provided with opening vertically, and the overcoat outer peripheral surface is provided with opening 5 vertically; The ring wall of ring and overcoat are provided with corresponding a plurality of locking holes 9 in two, and wherein the hole of an interior ring is a tapped hole, and ring is a through hole with the hole of overcoat in another, is provided with screw in the hole; Also be provided with screw thread removal hole 8 on the interior ring.
Adopt the swelling cover of above structure, when using it for the connection of wheel hub 7 and axle 6, in two, encircle and apply mechanically screw attachment outward, put it between axle 6 and the wheel hub 7, its overcoat and wheel hub are close to, and ring is embraced with axle in it, progressively screws screw with torque spanner then, up to the moment of torsion that reaches setting, along with the locking of screw, drive two interior hoops middle part extruding, under the effect of the inner conical surface of the male cone (strobilus masculinus) of interior ring and overcoat, ring extruding overcoat outwards expands the swelling wheel hub in two; Shrink in the interior hoop, axial compression is tight, and at this moment, it is firmly fixing that axle and wheel hub are connected expansion set, realized the connection of axle and wheel hub.Its stressing conditions is seen Fig. 3.During dismounting: all screws of dismantling earlier, but at this time because the reason of tapering, expansion set still is fixed on axle and the wheel hub, in two the knockout screw holes reserving of then two screws being packed into, can interior ring top is loose, then can be very light unload the swelling cover.
The utility model splines owing to noting be used on axle and the wheel hub, and the mechanical strength of axle and wheel hub improves, and use is loaded and unloaded very convenient.Have simple in structure, easy to loading and unloading, but the characteristics of overload protection can be widely used in axle and be connected the occasion that needs heavy load with wheel hub.
