Abstract
A joint slack has an effect of preventing an auxiliary slab rubber from deforming and breaking and a practical effect that the firmness is better, the compactness of the continuous action is better, and the torsibility is stronger. The utility model is characterized in that between pin and box subs of the joint slack, the circumference of the side of various rubber projections of the auxiliary slab rubber is designed into an arc convexity and is formed with an arc projection with an arc convex surface, and a lateral side in which a rotating projection of the pin and box subs is correspondingly contacted with an interlocking projection is equipped with a concave arc groove with a concave arc surface. Through the contacting of the arc convex surface of the arc projections and the concave arc surface of the concave arc groove, an effect of limiting the rubber projection can be formed to prevent the rubber projections from being compressed to the outer circumference to deform or even break by the rotating pressure, the strength of the endurance can be enhanced, and the larger rotating pressure can also be afforded. Besides because of limiting and preventing the outer projection, the utility model has a better effect of compactness, the conducting effect of the rotating force is better, which cause the joint slack to have a better practicability and a promotional effect.
Description
Technical field
The utility model relates to a kind of coupling.
Background technique
Motor shaft), the connector of driven spindle coupling is that (for example:, it comprises male and female connecting head 10,20 and is arranged on therebetween the flexible auxiliary blob of viscose 30 of summary tool (shown in Figure 1A) a kind of connection power shaft substantially, pegging graft more closely.
Existing structure, shown in Fig. 1 (B), be that public connecting head 10 is provided with according to setting spacing, a plurality of rotation projections 11 of wide cut, plug together groove 12, female connector 20 is also corresponding according to being set with, that sets the spacing wide cut plugs together groove 21, linked bump 22, public, female connector 10,20 the rotation projection 11 and the bi-side of linked bump 22, all be set as plane 13,23, again, auxiliary blob of viscose 30 is set as has the glue projection 31 that corresponding female connector 20 plugs together groove 21, the bi-side of glue projection 31 also are set as plane 33, and be formed with and plug together groove 32, the glue projection 31 of auxiliary blob of viscose 30 can be embedded in plugging together in the groove 21 of female connector 20, the rotation projection 11 of public connecting head 10 then can plug together in auxiliary blob of viscose 30 glue projections 31 formed plugging together in the groove 32, and formation connects one and allows power shaft 1 drive driven spindle 2 (as Fig. 2 A); Said structure has following shortcoming in fact:
1. power shaft 1 rotates and produces rotary torsion, rotate projection 11 via public connecting head 10, and form the glue projection 31 that powerful rotation pressure W acts on auxiliary blob of viscose 30, on business, the surface of contact of female connector and glue projection, be plane 13,23,33, it is a kind of planarea, do not give qualification, stop, thereby can protrude the phenomenon of being out of shape C and produce just like the extrusion effect shown in Fig. 2 B and the partial enlarged drawing to periphery, What is more, and this is out of shape C and causes the damage of breaking of protruding the position.
2. because of squeezing action, metaboly, 11 of the another side of glue projection 11 and rotation projections have the phenomenon of either large or small gap H, and influence the tightness that connects, and then influence the effect of interlock.
2. because of above-mentioned shortcoming, thus its can bear torque value less, be not durable.
Summary of the invention
In order to achieve the above object, the purpose of this utility model is to provide a kind of coupling, and it has better serviceability, can increase endurance strength, and can bear bigger transmission torsion and the good transmission effect of tightness is better.
In order to achieve the above object, the utility model provides a kind of coupling, comprise: male and female connecting head, auxiliary blob of viscose, male and female connecting head and auxiliary blob of viscose are respectively equipped with according to setting rotation projection that correspondence mutually plugs together, plug together groove and plug together groove, linked bump and glue projection, plug together groove, make male and female connecting head and auxiliary blob of viscose link one and can plug together mutually to be close to, should assist each glue projection of blob of viscose, bi-side all are set as the arc convex surface of arc projection shape; This public affairs connecting head respectively rotate projection, bi-side all are set as the concave arc groove shape concave arc surface of corresponding glue projection arc convex surface; Each linked bump of this female connector, bi-side also all are set as the concave arc groove shape concave arc surface of corresponding glue projection arc convex surface; Perhaps, each glue projection of this auxiliary blob of viscose, bi-side all are set as the concave arc surface of concave arc groove shape; This public affairs connecting head respectively rotate projection, bi-side all are set as the arc projection shape arc convex surface of corresponding glue projection concave arc surface; Each linked bump of this female connector, bi-side also all are set as the arc projection shape arc convex surface of corresponding glue projection concave arc surface.
The utility model has the advantages that:
One, will assist the glue projection bi-side of blob of viscose, be set as the arc convex surface of arc projection shape, and the male and female connecting head rotates the bi-side of projection, linked bump, be set as the concave arc surface of corresponding concave arc groove shape, the wedging of, concave arc protruding by arc, the effect that can form qualification, stops prevents that the glue projection from protruding distortion toward periphery, can guarantee bonding tightness, and then have the transmission effect that keeps splendid.
Two, by preventing the evagination distortion, the glue projection is squeezed entirely rotating projection, rotating between projection, do not have the problem of deformation fracture, and have effect more durable, that the increase endurance strength can bear bigger torsion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the existing three-dimensional exploded view of (A) coupling outward appearance (B);
Fig. 2 is that (B) extrusion distortion and local enlarged diagram are analysed and observe in existing coupling (A) combination;
Fig. 3 is the utility model three-dimensional exploded view;
Fig. 4 is that the utility model combination is analysed and observe and partial enlarged drawing.
Embodiment
Read to consult Fig. 3,4, the utility model comprises: male and female connecting head 40,50, auxiliary blob of viscose 60, male and female connecting head 40,50 and auxiliary blob of viscose 60 are respectively equipped with according to setting rotation projection 41 that correspondence mutually plugs together, plug together groove 42 and plug together groove 51, linked bump 52 and glue projection 61, plug together groove 62, and can plug together mutually to be close to male and female connecting head 40,50 and auxiliary blob of viscose 60 are linked into an integrated entity; Should assist each glue projection 61 of blob of viscose 60, bi-side all are set as the arc convex surface 63 of arc projection shape;
This public affairs connecting head 40 respectively rotate projection 41, bi-side all are set as the concave arc groove shape concave arc surface 43 of corresponding glue projection 61 arc convex surfaces 63;
