Description
Technical field
The invention belongs to mechanical equipment technical field, more particularly, to a kind of high-strength flexible shaft coupling.
Background technology
Shaft coupling is common component in machine driving, is mainly used to coupling spindle and axis or coupling spindle and other pivoting parts
Intermediate transmission mechanism, with transmit movement and torque.Some equipment can produce larger impact force when transmitting torque at present, because
This this kind equipment generally use balata belt is as shaft coupling transmission torque, but such Coupling Life is short, maintenance frequency
It is numerous, it is impossible to meet the larger transmission requirement of impact force, especially under the work condition environment of force-bearing situation complexity, shaft coupling easily damages
It is bad to be even broken, once and shaft coupling damages, be easy to cause equipment fault, or even easily trigger security incident.
The content of the invention
In view of this, the invention is intended to overcome above-mentioned defect existing in the prior art, proposes that a kind of high intensity is soft
Property shaft coupling.
To reach above-mentioned purpose, what the technical solution of the invention was realized in：
A kind of high-strength flexible shaft coupling, including intermediate connecting body and its first fixing sleeve of both sides connection and second are fixed
Set；The intermediate connecting body includes the bellows body portion at middle part, its both sides is respectively provided with solid with the first fixing sleeve or second
The connecting portion of fixed set connection；Side and second fixing sleeve inner wall of the first fixing sleeve inner wall away from the second fixing sleeve are remote
Side from the first fixing sleeve is equipped with metal reinforcing sleeve；Add on first fixing sleeve and the second fixing sleeve being not provided with metal
It is interlaced on the position covered by force to offer several line of rabbet joint；The line of rabbet joint is set along the cylindrical circumferential direction of corresponding fixing sleeve.
Further, the metal reinforcing sleeve is aluminum alloy sleeve.
Further, the line of rabbet joint is arranged at intervals, and every two lines of rabbet joint spacing is 5-10mm.
Further, the line of rabbet joint head and the tail both ends are equipped with arc sections.
Further, the slot length is the 1/3-1/2 of corresponding fixing sleeve circumferential length.
Further, the crest height in the bellows body portion is more than trough height.
Further, the width of the line of rabbet joint is 0.5-1.5mm.
Relative to the prior art, the invention has the advantage that：
The invention is reasonable in design, and intermediate connecting body is equipped with bellows body portion, has extremely strong anti-torsion ability,
Structural strength is high, even if applying under heavy duty, complicated operating mode, work that also can be steady in a long-term is hardly damaged.By in centre
Some lines of rabbet joint are set on the fixing sleeve of connector both sides, are effectively coordinated with intermediate connecting body, it is common to play anti-torsion effect, Gu
The fixed upper line of rabbet joint of set alleviates burden during intermediate connecting body hand torsion, keeps away as the transition between intermediate connecting body and axis body
Exempt from that torsional moment is excessively several to be applied on intermediate connecting body, ensure that shaft coupling overall structure uniform force is stablized.

Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can mechanically connect or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
A kind of high-strength flexible shaft coupling, as shown in Figure 1, being fixed including intermediate connecting body 1 and its both sides connect first
2 and second fixing sleeve 3 of set；The intermediate connecting body 1 includes the bellows body portion 4 at middle part, its both sides is respectively provided with and the
One fixing sleeve 2 or the connecting portion 5 of the second fixing sleeve 3 connection；The side of the first fixing sleeve inner wall away from the second fixing sleeve, with
And second side of the fixing sleeve inner wall away from the first fixing sleeve be equipped with metal reinforcing sleeve 6；First fixing sleeve and second is consolidated
Surely put on and interlaced on the position of metal reinforcing sleeve is not provided with offer several line of rabbet joint 7；The line of rabbet joint 7 is fixed along corresponding
The cylindrical circumferential direction for covering (the first fixing sleeve or the second fixing sleeve) is set.
Above-mentioned metal reinforcing sleeve 6 is aluminum alloy sleeve, light-weight, and intensity is high, and it is firm to ensure to be connected with corresponding axis body,
Stabilized structure, is not susceptible to damage.
The width of the above-mentioned line of rabbet joint 7 is 0.5-1.5mm, the line of rabbet joint be not easy it is wide, when shaft coupling is by pulling force or twisting force, if groove
Slit width is spent greatly, then causes deflection excessive, influence integrally-built stability.The above-mentioned line of rabbet joint 7 is arranged at intervals, between every two line of rabbet joint
Away from for 5-10mm.
In addition, above-mentioned 7 head and the tail both ends of the line of rabbet joint are equipped with arc sections 8.Set arc sections can be avoided effectively in groove
The end of seam forms stress concentration, avoids tearing in its end, causes the damage of shaft coupling.In general, 8 a diameter of 5- of arc sections
8mm, twice than slot width is bigger, effectively prevents stress concentration.
In general, in order to ensure that this shaft coupling has preferable anti-torsion and tensile capacity, above-mentioned 7 length of the line of rabbet joint is corresponding solid
Surely the 1/3-1/2 of circumferential length is covered, in the length range of the line of rabbet joint, the structure setting of the line of rabbet joint, and will not be to shaft coupling in itself
Rigidity produce excessive influence, be not in the situation because being twisted into two parts by torsion.
9 height of wave crest in above-mentioned bellows body portion 4 is more than the height of trough 10, due to when bending or reversing, shaft coupling
Deformation on device outer circumference surface is bigger than its inner side deflection, therefore, at excircle needs the structural strength of higher, and ensure cylindrical
All places can produce the deflection than inner side bigger, could preferably ensure the work of shaft coupling monolithic stability, be not susceptible to damage
It is bad.Therefore, crest height is more than trough height, so that wave crest energy opposed valleys produce the deformation quantity of bigger, meanwhile, at wave crest
Section is greater than section at trough, to improve its intensity.
The invention is reasonable in design, and intermediate connecting body is equipped with bellows body portion, has extremely strong anti-torsion ability,
Structural strength is high, even if applying under heavy duty, complicated operating mode, work that also can be steady in a long-term is hardly damaged.By in centre
Some lines of rabbet joint are set on the fixing sleeve of connector both sides, are effectively coordinated with intermediate connecting body, it is common to play anti-torsion effect, Gu
The fixed upper line of rabbet joint of set alleviates burden during intermediate connecting body hand torsion, keeps away as the transition between intermediate connecting body and axis body
Exempt from that torsional moment is excessively several to be applied on intermediate connecting body, ensure that shaft coupling overall structure uniform force is stablized.
The foregoing is merely the preferred embodiment of the invention, is not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on, should be included in the invention
Protection domain within.
