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 monoblock type shaft coupling, as shown in Figures 1 to 3, including internal matrix 1 and the sheath 2 in the outside of matrix 1；It is described
The fixed cover 4 that matrix 1 includes middle spiral elasticity body 3 and its both ends are set, side is provided with linkage section to the fixed cover 4 outwardly
5；The spiral elasticity body 3 and its fixed cover 4 at both ends are wrapped up by sheath 2 simultaneously；Covering thickness is big on the spiral elasticity body 3
In covering thickness on fixed cover, and the internal diameter for being enclosed with the spiral elasticity body portion of sheath is more than the internal diameter of fixed cover part；Institute
State and several connecting holes 6 are along the circumferential direction laid with linkage section 5.It is pointed out that sheath 2 preferably uses activeness and quietness Buddhist nun
Imperial layer, itself have stronger impact resistance, intensity height and with certain elasticity.The sheath time processing of matrix outer
Shaping, for integral coating on the outside of matrix, shaft coupling resistance to overturning is reliably ensured that balance is more preferable.
Generally, it is enclosed with internal diameter of the internal diameter than the fixed cover part 8 of the spiral elasticity body portion 7 of the sheath
Big 5-10mm.After being connected using fixed cover with corresponding axis body, the inwall of cavity 9 in the middle part of shaft coupling will not touch axis body,
Also, during equipment operation, because shaft coupling middle spiral elastomer portion has certain deformation, its internal diameter is more than solid
Surely internal diameter 5-10mm is covered, the part where effectively ensureing spiral elasticity body will not interfere with the axis body being connected.
The transition position of above-mentioned spiral elasticity body 3 and sheath on fixed cover 4 is cone structure, and covering thickness is by spiral bullet at this
Property body be gradually reduced to fixed cover side, avoid the two sheath crossover position produce stress concentration, ensure that overall knot
The stability of structure.
Above-mentioned spiral elasticity body 3 preferably uses helical spring, has good tension, resistance to compression and anti-twisting property, with shield
Rotating fields coordinate, and greatly improve the tension and anti-twisting property of shaft coupling, under complicated, heavy duty operating mode, it may have
Longer service life.Certainly, spiral elasticity body using other materials material can also, as long as can be good at realizing skeleton
Supporting role, and there is higher elasticity, it is preferred after reversing stretching without permanent deformation.
When this shaft coupling is by torsion force, spiral elasticity body has certain rigidity in itself, is turned round as among shaft coupling
Turn the skeletal support of crushed element, while itself can produce certain deformation, also effectively inhibit excessive deflection, protect
It is reliable to hinder shaft coupling monolithic stability, it is not easily damaged.
Above-mentioned fixed cover 4 is aluminium alloy fixed cover, and light weight, intensity is high, is connected with axis body reliably.
What is be spaced on the sheath in the outside of above-mentioned spiral elasticity body 3 is provided with several line of rabbet joint 10, the line of rabbet joint 10 along sheath outside
Circumferencial direction is set.Specifically, the depth of the line of rabbet joint is the 1/3-1/2 of covering thickness, its width is 0.5-1.5mm.Line of rabbet joint depth
Unsuitable too deep, if groove depth is excessive, sheath is easily broken when by pulling force or torsion at the line of rabbet joint, if groove depth mistake
It is small, then the good anti-torsion of helical cut groove and the deformability of stretch-proof can not be played, does not reach optimal antitorque effect.
In an optional embodiment, the above-mentioned head and the tail both ends of the line of rabbet joint 10 are equipped with arc sections 11.Set arc sections
It can effectively avoid forming stress concentration in the end of the line of rabbet joint, avoid tearing in its end, cause the damage of shaft coupling.It is logical
Often, 11 a diameter of 5-8mm of arc sections, twice than slot width is bigger, effectively prevents stress concentration, will not during torsional deflection
Torn in end of slot.
The invention shaft coupling is monolithic construction, and its stability is stronger, and centre position is provided with spiral elasticity body, spiral shell
What is be spaced on sheath on the outside of rotation elastomer is provided with several line of rabbet joint, with spiral elasticity body mating reaction, considerably increases shaft coupling
Anti-twisting property and impact resistance, even if apply complexity work condition environment under, its service life also has reliable guarantee.
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.
