Description
Technical field
The present invention relates to shaft joint field more particularly to a kind of splined shaft yielding couplings.
Background technique
Shaft coupling is to be allowed to rotate jointly to transmit for two axis (driving shaft and driven shaft) coupled in different institutions
The machine components of torque.Shaft coupling is many kinds of, according to the connection type situation for being connected two axis, can be divided into: rigid shaft coupling
Device and yielding coupling.
In the transmission system of ultrasonic-frequency rotory generator group, splined shaft and matched splined shaft shaft coupling can be usually used
Device.In traditional technology, positive coupling is widely used；Rigid spline housing of the spline fitted on shaft coupling on splined shaft
On, to guarantee that concentricity is sufficiently small when transmitting torque between driving shaft and transmission shaft.However, splined shaft meeting in high speed rotation
Vibration is generated, this to have shock between spline and spline housing, this also greatly accelerates the abrasion of spline.
Since elastic shaft joint is equipped with elastic buffer structure, helicla flute or parallel slot are such as opened up on shaft coupling, and
It is to use the components such as elastomeric pad or bellows in the connecting portion of shaft coupling, yielding coupling has the function of buffering, vibration damping；Such as
Fruit uses traditional yielding coupling in above-mentioned ultrasonic-frequency rotory generator group, and the available part of the above problem solves；But by
In the essence of such elastic connection, the relative movement between connected component is allowed for, this just brings driving shaft and transmission shaft
Between when transmitting torque the excessive problem of concentricity (the accessible concentricity of traditional elastic shaft coupling be 0.5-0.8 millimeters),
The performance of traditional elastic shaft coupling this aspect also needs further technical solution to be resolved.
Summary of the invention
The splined shaft elasticity that spline wear and lesser concentricity can be mitigated the invention is intended to provide one kind
Shaft coupling.
Splined shaft yielding coupling in this programme, including ring flange, spline housing are provided with counterbore on the ring flange,
The spline housing is multiple annular metal pieces overlapped together, which is compacted compressing parts under the counterbore
It is in heavy portion and coaxial with counterbore, spline is circumferentially distributed on the inner wall of spline housing, the spline with need to connect the flower in it
Key cooperation.
Working principle and beneficial effect: the splined shaft for needing to connect cooperates in yielding coupling, the required and splined shaft
The component of connection can be fixed on ring flange；When the spline on splined shaft since high speed rotation and the keyway generation on spline housing are touched
When hitting, a part of kinetic energy is can be absorbed and via ring because have tiny gap in the annular metal piece that overlaps together
The mutual small file turn of shape sheet metal is changed to elastic potential energy, to achieve the effect that bumper and absorbing shock, alleviates spline
Abrasion；Meanwhile laminating and being pressed on the annular metal piece in ring flange there is characteristic close to positive coupling, it can allow connection two
End concentricity is reduced in the range of 02.-0.5 millimeters, solves the problems, such as that traditional elastic concentricity of coupling is excessively high.
It advanced optimizes, the fixing piece is specially screw, which passes through circumferentially distributed on the shaft coupling lead to
Spline housing is pressed on the counterbore bottom surface of ring flange by hole；Screw is common part, and such compression mode is simple and easy, just
In installing and dismounting and cleaning, at the same can also by way of tightening or unclamping screw to the compaction degree of the spline housing into
Row adjustment.
It advanced optimizes, the stacking factor of spline housing is more than or equal to 0.97, less than 1.
Stacking factor herein refers to: thickness summation/annular metal piece of annular metal piece laminate after actual (real) thickness.
It follows that stacking factor is up to 1, i.e. thickness summation is equal to actual (real) thickness；Stacking factor is more than or equal to 0.97,
So that annular metal piece is laminated enough to close close, there is rigidity to ensure that and laminate rear spline housing, and then guarantee shaft coupling
Device concentricity sufficiently small when being driven；Stacking factor ensure that there are tiny gaps between annular metal piece, can play less than 1
The effect of buffering.
It advanced optimizes, the cyclic annular steel plate of the annular metal piece concretely 1 millimeters thick, such ring-type steel plate is easy to
Processing, reduces the production cost of the splined shaft yielding coupling.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of spline of embodiment of the present invention yielding coupling；
Fig. 2 is the front view of spline of embodiment of the present invention yielding coupling.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
Appended drawing reference in Figure of description includes: ring flange 1, spline housing 2, screw 3.
The present embodiment is as shown in Figure 1 and Figure 2: spline yielding coupling, including ring flange 1, spline housing 2 and screw 3, flower
Key set 2 overlaps together for the cyclic annular steel plates of several 1 millimeters thicks, circumferentially distributed on each ring-type steel plate to have a through-hole, when stacking
Through-hole on each ring-type steel plate forms a long through-hole to it, and the through-hole that screw 3 passes through these length protrudes into institute on ring flange 1
The bottom surface of counterbore is opened, and is fixedly connected by the threaded hole on the bottom surface with ring flange 1, while entire spline housing 2 being pressed on
On ring flange 1；It is 0.97 that the stacking factor of spline housing 2, which is used, the spline housing 2 to guarantee the rigidity characteristic of spline housing 2, after compression
Inner wall forms several splines.
The present embodiment course of work is as follows: in the splined shaft cooperation yielding coupling for needing to connect, the required and splined shaft
The component of connection can be fixed on ring flange 1；When the spline on splined shaft since the keyway in high speed turn and spline housing 2 generates
When collision, because having tiny gap between the cyclic annular steel plate overlapped together, a part of kinetic energy is can be absorbed in spline housing 2, and
It is changed to elastic potential energy via the mutual small file turn of cyclic annular steel plate, to achieve the effect that bumper and absorbing shock, alleviates flower
The abrasion of key；It laminates simultaneously and is pressed on the sufficiently high stacking factor of cyclic annular steel plate in ring flange 1, thus be provided with close to rigid
Property shaft coupling characteristic, can allow connection both ends concentricity be reduced in the range of 02.-0.5, it is same to solve traditional elastic shaft coupling
The heart spends high problem.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific embodiment can be used for explaining the content of claim.
