Description
Technical field
The utility model relates to coupling technical field, particularly relates to a kind of Longmen machine tool coupling.
Background technique
Coupling is as motor transferring power, for driving shaft and driven shaft are linked together, although can meeting general job requirement, existing coupling there are a lot of defects, first, existing Longmen machine tool coupling cannot be the installing and using of the distance overlength that realize to connect, and in High Rotation Speed process, entire length is long, because of concentricity, dynamic balancing is processed bad, can cause great injury to spindle motor.And motor power when operation is very large, existing Longmen machine tool Coupling Life cannot meet intensive work demand and use for a long time, once diaphragm deforms or ruptures, personal security is constituted a threat to, because dynamic balance grade does not reach requirement, can bring great infringement to machine tool chief axis integral body, inevitably shake, or even the phenomenon such as distortion, thereby the bias that the two Shaft misalignment hearts produce affected, drift angle, axial displacement.
Model utility content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of Longmen machine tool coupling is provided.
For realizing the technological scheme that the purpose of this utility model adopts, be:
A kind of Longmen machine tool coupling, comprise that two ends are formed with the intermediate of adpting flange, two groups of metal plate springs groups that are fixedly connected on respectively intermediate two ends, two are separately positioned on both sides expansion connecting sleeve, described expansion connecting sleeve comprises flange plate and flange cover, described flange plate is corresponding with metal plate springs group be fixedly connected with and its on be formed with expansion set, described flange cover center is formed with the taper hole mating with described expansion set tapering and is fixedly connected with described flange plate by bolt.
Described metal plate springs group is formed by fixedly connecting by multi-disc leaf spring, described metal plate springs is sheet ring, in the described even compartment of terrain of metal plate springs outer rim, be formed with 6 circular arc cutaway, on the leaf spring between two circular arc cutaway, be formed with through hole.
Described multi-disc metal plate springs riveting.
At described flange, put and be provided with demounting bolt.
Compared with prior art, the beneficial effects of the utility model are:
Being designed beautifully of coupling of the present utility model, assembly precision is high, simple in structure, and the life-span is long.Wherein, described intermediate is the tubular structure that two ends are formed with adpting flange, tubular structure length in the middle of lengthening, greatly improved the applicability to Longmen machine tool coupling, at its two ends, by metal plate springs group, two expansion connecting sleeves are set respectively simultaneously, symmetric design theory can reduce the amount of unbalance of self, in the processing through high-precision dynamic balancing level, can make coupling in high speed using process, guarantee the stability of superelevation.And produce distortion and then hold axle tightly by tightening the expansion set that pressurization bolt makes flange plate, precision is high, and speed is fast, has the torsional rigid of maximum level, is best suited for the coupling that Longmen machine tool is used.
Accompanying drawing explanation
Figure 1 shows that structural representation of the present utility model;
Figure 2 shows that metal plate springs group side-looking structural representation of the present utility model;
Figure 3 shows that metal plate springs group cross section structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, Longmen machine tool coupling of the present utility model comprises that two ends are formed with the intermediate 1 of adpting flange 2, two groups of metal plate springs groups that are fixedly connected on respectively intermediate two ends 2, two expansion connecting sleeves that are separately positioned on both sides, described expansion connecting sleeve comprises flange plate 4 and flange cover 5, described flange plate is corresponding with metal plate springs group be fixedly connected with and its on be formed with expansion set 6, described flange cover center is formed with the taper hole mating with described expansion set tapering and is fixedly connected with described flange plate by bolt.Wherein, the adpting flange of flange plate and the adpting flange of intermediate are oppositely arranged but are not directly bolted to connection, but be fixedly connected with and realize both being fixedly connected with metal plate springs group respectively, the fixing bolt of indication generally refers to that bolt connects herein, for realizing above-mentioned connection, through hole, counterbore and tapped hole etc. need to be set on each adpting flange, and this no longer launches to describe at this similarly to the prior art.
Wherein, described intermediate is the tubular structure that two ends are formed with adpting flange, middle tubular structure length can lengthen, greatly improved the applicability to Longmen machine tool coupling, at its two ends, by metal plate springs group, two expansion connecting sleeves are set respectively simultaneously, symmetric design theory can reduce the amount of unbalance of self, in the processing through high-precision dynamic balancing level, can make coupling in high speed using process, guarantee the stability of superelevation.And produce distortion and then hold axle tightly by tightening the expansion set that pressurization bolt makes flange plate, precision is high, and speed is fast, has the torsional rigid of maximum level, is best suited for the coupling that Longmen machine tool is used.
Further, described metal plate springs group 3 is formed by fixedly connecting by multi-disc leaf spring 31, described metal plate springs is sheet ring, the even compartment of terrain of outer rim in described metal plate springs is formed with 6 circular arc cutaway 32, is formed with through hole 33 with by the stacked rear riveting of a plurality of leaf springs on the leaf spring between two circular arc cutaway.The structure that adopts lamination diaphragm group, can regulate the distance between driving shaft and driven shaft automatically, the bias producing in can compensating motion, drift angle, axial displacement, makes motion more stable, reliably, make coupling in the situation that the diameter of axle is identical, rated torque is higher than other diaphragm coupling, and transmitted power moment of torsion is large, reduce inrush current power, friction, noise free, also can extend working life.
Further, the flange plate on described coupling and flange cover is taper fit, and the taper design of optimization produces it to be out of shape to obtain more uniform stress distribution, to hold mandrel tightly when tightening pressurization bolt by expansion set.Crack or the infringement of any form to coupling from so avoiding.
Further, at described flange, put and be provided with demounting bolt, at flange, put at least two tapped through holes are set symmetrically, described demounting bolt is connected with described tapped through hole, in the time need to dismantling, precession demounting bolt can utilize demounting bolt end and holding of flange plate that both are separated, and realizes quick-detachment.Meanwhile, on flange cover and flange plate, also centering body can be set, improve installation efficiency and self-aligning function.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
