Abstract
The utility model provides a kind of diaphragm coupling special screw, comprise: countersunk head, linkage section and thread section, in the middle of described countersunk head and linkage section, the first groove is set, second groove is set between described linkage section and thread section, described thread section arranges outside thread, and described countersunk head, linkage section and thread section are structure as a whole.The diaphragm coupling special screw that the utility model provides carries out fastening by arranging linkage section to diaphragm coupling, during use, two half-couplings are by being stuck in the linkage section of special screw, carry out fastening at thread section mounting nuts, the diametric fit of the diameter at linkage section place and two half-couplings, two half-couplings and the seamless suit of linkage section, improve the connection tightness of diaphragm coupling, improve the service precision of coupling, structure is simple.
Description
Technical field
The utility model relates to coupling equipment, is specifically related to a kind of diaphragm coupling special screw.
Background technique
Diaphragm coupling is connected with two half-couplings alternately by several groups of diaphragms bolt, often organize diaphragm to be formed by several pieces folded collection, diaphragm is divided into linkage type and difform full slice system, diaphragm coupling by the resiliently deformable of diaphragm compensate join the relative displacement of diaxon, be a kind of high performance metallic member flexible coupling, be applicable to high temperature, at a high speed, have the axle system transmission of aggressive medium work condition environment.
Coupling in use, can produce very large internal pressure, and coupling connects the premature breakdown closely easily not causing coupling.
Model utility content
In order to overcome above-mentioned prior art Problems existing, the utility model provides a kind of diaphragm coupling special screw, prevents diaphragm coupling connection from closely not affecting it and normally uses, cause the problem of security incident.
The technical solution of the utility model is: a kind of diaphragm coupling special screw, comprise: countersunk head, linkage section and thread section, in the middle of described countersunk head and linkage section, the first groove is set, second groove is set between described linkage section and thread section, described thread section arranges outside thread, and described countersunk head, linkage section and thread section are structure as a whole.
Further, the outer surface of described linkage section is light face structure.
Further, the diameter of described countersunk head is 7.5mm, and thickness is 3mm; The diameter of described linkage section is 5.99mm ~ 6.05mm, and length is 8mm, and the diameter of described thread section is 5mm, and length is 6.5mm.
Further, the diameter of described first groove is 5.4mm, and the diameter of described second groove is 4mm.
The beneficial effects of the utility model are: the diaphragm coupling special screw that the utility model provides carries out fastening by arranging linkage section to diaphragm coupling, during use, two half-couplings are by being stuck in the linkage section of special screw, carry out fastening at thread section mounting nuts, in the utility model embodiment, the diametric fit of the diameter at linkage section place and two half-couplings, two half-couplings and the seamless suit of linkage section, improve the connection tightness of diaphragm coupling, improve the service precision of coupling, structure is simple.
Accompanying drawing explanation
Fig. 1 is a kind of diaphragm coupling special screw structural drawing that the utility model proposes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1, it is a kind of diaphragm coupling special screw structural drawing that the utility model proposes.
As shown in Figure 1, a kind of diaphragm coupling special screw, comprise: countersunk head 1, linkage section 2 and thread section 3, in the middle of described countersunk head 1 and linkage section 2, the first groove 4 is set, second groove 5 is set between described linkage section 2 and thread section 3, described thread section 3 arranges outside thread, and described countersunk head 1, linkage section 2 and thread section 3 are structure as a whole.
Further, the outer surface of described linkage section 2 is light face structure.
Further, the diameter of described countersunk head 1 is 7.5mm, and thickness is 3mm; The diameter of described linkage section 2 is 5.99mm ~ 6.05mm, and length is 8mm; The diameter of described thread section 3 is 5mm, and length is 6.5mm.
Further, the diameter of described first groove 4 is 5.4mm, and the diameter of described second groove 5 is 4mm.
The diaphragm coupling special screw that the utility model provides carries out fastening by arranging linkage section to diaphragm coupling, during use, two half-couplings are by being stuck in the linkage section of special screw, carry out fastening at thread section mounting nuts, in the utility model embodiment, the diametric fit of the diameter at linkage section place and two half-couplings, two half-couplings and the seamless suit of linkage section, improve the connection tightness of diaphragm coupling, improve the service precision of coupling, structure is simple.
Above the utility model is described in detail, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
