Abstract
The utility model intends to solve the problem how to eliminate the residual expansion force when disassembling the multi-slot elastic sleeve expansion coupling device for convenient disassembly, and is characterized in that the multi-slot elastic sleeve is supplemented with a closing ring and a plurality of screws. The closing ring is positioned on the end surface of the multi-slot elastic sleeve, thus stopping the expansion bolt. When the expansion bolt is screwed in the direction opposite to the expansion force, the side of the bolt props up the closing ring and drives the closing ring to move axially. The multi-slot elastic sleeve distorts toward the elongating direction and restores the original shape so as to eliminate the residual expansion force. The utility model has a fewer parts supplemented, a simple structure, and is easy to disassemble, hereby laying a solid foundation for the promotion and application of the multi-slot elastic sleeve expansion coupling device.
Description
Technical field:
The utility model relates to a kind of keyless device.
Background technique:
Swelling connects because centering property is good; can along the circumferential direction reach axial direction and regulate two coupled relative position, have characteristics such as overload protection function, replace key connecting just gradually; be widely used in various propeller boss and connect, particularly require in the servo drive system of zero-clearance transmission.Now, Chang Yong swelling is connected with conical ring swelling connection and two kinds of forms of conical surface swelling cover swelling connection.Wherein, structure standardization, seriation that the swelling of conical surface swelling cover connects, JB/T7934-1995 swelling connects to conical surface swelling cover structure, base dimension and parameter provide with the form of form, use more convenient, though connecting, the conical ring swelling excludes NBS, but relevant design handbook and books all have detailed introduction and analytical calculation to it, and this applies the condition created for it.It is another kind of new swelling connecting mode that the swelling of multiple-grooved elastic sleeve connects, and it overlaps with common swelling, and swelling connects and conical ring swelling connection relatively has characteristics such as component part is few, simple in structure, transmitting torque is big, has application promise in clinical practice.Multiple-grooved elastic sleeve swelling coupling arrangement is because component part is few, and it is comparatively convenient to assemble.The multiple-grooved elastic sleeve is placed in the middle of coupled transmission shaft and the coupled wheel hub, tightens cinch bolt, the multiple-grooved elastic sleeve produces resiliently deformable, and transmission shaft and wheel hub are linked together.When needing dismounting, unclamp cinch bolt, the multiple-grooved elastic sleeve should return to original-shape immediately, and tension force is eliminated, so that dismounting.But find in the actual application, in some cases, because the effect of swelling frictional force and the influence of the part plastic deformation that long swelling effect is produced, after unclamping cinch bolt, the multiple-grooved elastic sleeve can not resile immediately, also can there be certain remaining tension force, brings certain difficulty to dismounting.
Summary of the invention:
The purpose of this utility model is to solve how multiple-grooved elastic sleeve swelling coupling arrangement eliminates remaining tension force when dismounting problem, so that dismounting.A kind of multiple-grooved elastic sleeve swelling coupling arrangement is uniform-distribution with several bolts hole on the multiple-grooved elastic sleeve, two ends at bolt hole, one end is a tapped hole, the other end is a counterbore, counterbore is used for holding the head of hexagon socket head cap screw, it is characterized in that: the multiple-grooved elastic sleeve also is uniform-distribution with several screw holes on the end face of an end that has counterbore, fixes a back-up ring by screw on the end face of multiple-grooved elastic sleeve.Described back-up ring by screw on the end face of multiple-grooved elastic sleeve, block cinch bolt, when turning cinch bolt with the opposite direction of swelling, back-up ring will be withstood in the end of bolt, driving back-up ring in axial direction moves, the multiple-grooved elastic sleeve is out of shape to prolonging direction, makes it return to original-shape, to eliminate remaining tension force.The utility model applies a power in when dismounting to the multiple-grooved elastic sleeve, the direction of this power with make multiple-grooved elastic sleeve swelling applied force direction opposite, force the multiple-grooved elastic sleeve to return to original-shape, finally reach the purpose of the remaining tension force of elimination.The part that multiple-grooved elastic sleeve swelling coupling arrangement after the improvement increases is few, simple in structure, makes dismounting become very easy, is the further basis of having tamped of applying of multiple-grooved elastic sleeve swelling coupling arrangement.
Description of drawings:
Fig. 1 is the utility model multiple-grooved elastic sleeve swelling connecting device structure figure.
Fig. 2 is multiple-grooved elastic sleeve force analysis figure.
Fig. 3 is the utility model multiple-grooved elastic sleeve structural drawing.
Embodiment:
As shown in fig. 1, in multiple-grooved elastic sleeve swelling coupling arrangement, 1 be cinch bolt; 2 is wheel hub; 3 is the multiple-grooved elastic sleeve; 4 is transmission shaft; 5 is screw; 6 is back-up ring.Wherein wheel hub 2, transmission shaft 4 are coupled; By cinch bolt 1, multiple-grooved elastic sleeve 3, screw 5, back-up ring 6 totally 4 parts constitute coupling arrangement, back-up ring 6 is fixed together by screw 5 and multiple-grooved elastic sleeve 3.When tightening cinch bolt 1 clockwise, the multiple-grooved elastic sleeve will produce the swelling distortion, see Fig. 2, and the tension force that the swelling distortion produces is linked together wheel hub 2 and transmission shaft 4.When counterclockwise unclamping cinch bolt 1, and continue when counterclockwise turning cinch bolt 1, the head of cinch bolt 1 will withstand back-up ring 6, and it is in axial direction moved, thereby make the multiple-grooved elastic sleeve in axial direction extend and resile.
As shown in Figure 2, the multiple-grooved elastic sleeve produces resiliently deformable under the effect of the F power that cinch bolt 1 provides.Resiliently deformable acts on transmission shaft 4 and the wheel hub 2, produces tension force N

3, its big I is tried to achieve by following formula:
N
1＝F/[1.2(cosα+μsinα)+2(μcosα-sinα)]

3＝S
2(cosβ+0.3sinβ)/[(0.3+2μ)cosβ-(1-0.6μ)sinβ]
After cinch bolt 1 became flexible, F power was removed thereupon.But because tension force N

3To hinder the multiple-grooved elastic sleeve and resile, thereby produce remaining tension force, be unfavorable for dismounting.If apply a power opposite, help the multiple-grooved elastic sleeve to resile N with the F force direction to the multiple-grooved elastic sleeve

3To eliminate, remaining tension force also will be eliminated thereupon thereupon.The power opposite with the F force direction is still provided by cinch bolt 1.
As shown in Figure 3, be uniform-distribution with several bolts hole on the multiple-grooved elastic sleeve, at the two ends of bolt hole, an end is a tapped hole, and the other end is a counterbore, and counterbore is used for holding the head of hexagon socket head cap screw.The multiple-grooved elastic sleeve also is uniform-distribution with several screw holes on the end face of an end that has counterbore, be used for fixing back-up ring 6.
