Description
Technical field
The utility model belongs to Helicopter Transmission System design field, relates to a kind of laminated diaphragm couplings.
Background technique
As shown in Figure 1, 2, 3, laminated diaphragm couplings utilizes link to be cross-linked two coupling.Laminated diaphragm couplings compensates the relative displacement of coupling shaft by the distortion of lamination, be a kind of high performance metallic elastic component flexible coupling.Laminated diaphragm couplings is widely used in the fields such as aviation, boats and ships and engineering machinery.Compared with the coupling of laminated diaphragm couplings and other type, there is no relative sliding, do not need lubricated and sealing, noiseless, simple in structure, cost is lower.Laminated diaphragm couplings is main transmitting torque in Helicopter Transmission System, and can carry out certain axial displacement and radial angle compensation.
Domestic and international existing laminated diaphragm couplings main structure form as shown in Figure 1, is mainly made up of lamination, lining, packing ring etc.The attachment hole of lamination is evenly distributed on the circumferential of lamination.
Insufficient to the loading characteristic consideration under its working condition in tradition laminated diaphragm couplings structural design, in real work situation, easily occur due to excessive lamination layering and the twisted phenomena of producing of moment moment of torsion, the destruction of causing laminated diaphragm couplings.
Model utility content
The technical problems to be solved in the utility model: a kind of laminated diaphragm couplings is provided, improves the torque-transfer capability of laminated diaphragm couplings in the situation that not affecting its angle compensation ability.
The technical solution of the utility model: a kind of laminated diaphragm couplings, comprising:
Lamination, lining, pad, lamination is hollow plum blossom-shaped, and lamination petal is even number, and each petal is provided with mounting hole, and the petal of lamination is one group between two, the distance between petal is on the same group less than petal on the same group and arrives the adjacent distance of organizing petal; Lining is tubular structure, and lining one end inwall has spinning groove, and the lining the other end is boss structure; Pad one side has chamfering; Lining has one end of spinning groove and inserts successively mounting hole and the pad on lamination petal, and has a side of chamfering to pass from pad, and lining spinning groove is pressed in pad chamfering.
The beneficial effects of the utility model: the utility model is compared with traditional laminated diaphragm couplings structural type, consider the stress form of the different parts of laminated diaphragm couplings under working condition, by changing the angle value of active coupling attachment hole and passive coupling attachment hole and carrying out the processing of different size for the outer rim of different stress areas, guarantee do not changing under the prerequisite of torque-transfer capability, obviously improve the buckling strength of lamination, strengthen the ability that it transmits instantaneous high pulling torque, thereby improve the life-span of flexible laminated membrane coupling.

Embodiment
Below the utility model is described in further details.
As shown in Fig. 5,6,7, a kind of laminated diaphragm couplings of the utility model, comprising:
Preferably, the petal of lamination 1 has 6.
For wear prevention lamination 1, between lining 2 and lamination 1, between pad 3 and lamination 1, be all provided with packing ring.
Lamination is Thin Elastic steel disc, can be formed by stacking for a lot of laminates.
Core of the present utility model is to strengthen the anti-unstability of lamination (anti-flexing) ability.Laminated diaphragm couplings is formed by connecting by lining by some laminations, transmitting torque that can be stable under load rating.In the time there is slight overload, may there is the flexing of lamination, thereby cause the stratification of lamination, and then affect the damage of lamination.
Addressing the above problem is mainly the influence factor of the anti-flexion capabilities of analyzing influence lamination, and considers the impact of new configuration on lamination torque-transfer capability.Typical case's lamination comprises some groups of uniform attachment holes, and initiatively coupling is connected with stack of laminations with passive coupling is staggered.Can improve the buckling loads of lamination constricted zone by reducing the angle of active coupling attachment hole and passive coupling attachment hole.But reduce the deformation-compensated ability that this angle will cause constricted zone, therefore in pressurized zone outer rim, notch size adjustment is strengthened to its deformation-compensated ability.By adjusting angle and root radius size, flexural rigidity and buckling loads are carried out to Conjoint Analysis, finally obtain optimal result.
6 mounting holes of tradition lamination are evenly distributed in the circumferential of lamination, open a hole every 60 °; Between two holes, outer rim root radius is identical.The utility model lamination, adjacent two orifice angle are a1 and a2, the corresponding R1 of outer rim root radius and R2 between two holes.According to lamination size and suffered stress analysis, determine outer rim root radius R1, R2 between a1, a2 and two holes, wherein guaranteeing a1 and a2(Fig. 4) sum is 120 °, pressurized zone outer rim root radius R1 is less than tension outer edge area outer rim root radius R2.Prove by force analysis, this configuration is stressed more reasonable, and the life-span is longer.
