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 the part commonly used in machine driving, is mainly used to coupling spindle and axle or coupling spindle and other pivoting parts
Intermediate transmission mechanism, with transmit motion and torque.Some equipment can produce larger impulsive force when transmitting torque at present, because
This this kind equipment generally use balata belt transmits torque as shaft coupling, but such Coupling Life is short, maintenance frequency
It is numerous, it is impossible to meet the larger transmission requirement of impulsive force, especially under the complicated work condition environment of force-bearing situation, shaft coupling easily damages
It is bad to be even broken, once and shaft coupling damages, easily cause equipment fault, or even easily trigger security incident.
The content of the invention
In view of this, the invention is intended to overcome defect present in above-mentioned prior art, proposes that a kind of high intensity is soft
Property shaft coupling.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
A kind of high-strength flexible shaft coupling, including intermediate connector and its first fixed cover of both sides connection and second are fixed
Set；The intermediate connector includes the bellows body portion at middle part, and its both sides is respectively provided with solid with the first fixed cover or second
The connecting portion of fixed set connection；Side and second fixed cover inwall of the first fixed cover inwall away from the second fixed cover are remote
Side from the first fixed cover is equipped with metal reinforcing sleeve；Add on first fixed cover and the second fixed cover 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 fixed cover.
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 fixed cover 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 prior art, the invention has the advantage that：
The invention is reasonable in design, and intermediate connector is provided 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 fixed cover of connector both sides, effectively coordinated with intermediate connector, it is common to play anti-torsion effect, Gu
Surely the line of rabbet joint put alleviates burden during intermediate connector hand torsion, kept away as the transition between intermediate connector and axis body
Exempt from that torsional moment is excessively several to be applied on intermediate connector, ensure that shaft coupling overall structure uniform force is stable.

Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of high-strength flexible shaft coupling, as shown in figure 1, being fixed including intermediate connector 1 and its both sides connect first
The fixed cover 3 of set 2 and second；The intermediate connector 1 includes the bellows body portion 4 at middle part, and its both sides is respectively provided with and the
One fixed cover 2 or the connecting portion 5 of the second fixed cover 3 connection；The side of the first fixed cover inwall away from the second fixed cover, with
And second side of the fixed cover inwall away from the first fixed cover be equipped with metal reinforcing sleeve 6；First fixed cover and second is consolidated
Surely put 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 fixed cover or the second fixed cover) is set.
Above-mentioned metal reinforcing sleeve 6 is aluminum alloy sleeve, in light weight, and intensity is high, and it is firm to ensure to be connected with corresponding axis body,
Stabilized structure, it 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, the above-mentioned head and the tail both ends of the line of rabbet joint 7 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.Generally, 8 a diameter of 5- of arc sections
8mm, twice than slot width is bigger, effectively prevents stress concentration.
Generally, in order to ensure that this shaft coupling has preferable anti-torsion and tensile capacity, the above-mentioned length of the line of rabbet joint 7 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 again 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.
The height of crest 9 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, higher structural strength is needed at excircle, and ensure cylindrical
All places can produce the deflection bigger than inner side, 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 crest energy opposed valleys produce bigger deformation quantity, meanwhile, at crest
Section is greater than section at trough, to improve its intensity.
The invention is reasonable in design, and intermediate connector is provided 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 fixed cover of connector both sides, effectively coordinated with intermediate connector, it is common to play anti-torsion effect, Gu
Surely the line of rabbet joint put alleviates burden during intermediate connector hand torsion, kept away as the transition between intermediate connector and axis body
Exempt from that torsional moment is excessively several to be applied on intermediate connector, ensure that shaft coupling overall structure uniform force is stable.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
Protection domain within.
