    • 专利摘要:
    A spring steel, liquid-damped shaft coupling in which the torque is transmitted between an inner part and an outer part coaxial therewith by means of radial spring elements disposed in discrete liquid-filled chambers, the liquid in any chamber being displaced, in response to a relative movement, by the spring elements into the adjacent chamber; outwardly axially parallel torsion spring elements are provided on the radial spring elements and connect the same to the outer coupling part. To increase the torsional resilience, therefore, a torsion tube is connected to each radial spring element and projects axially on one side relative to the radial spring element; and a torsion bar extends in the torsion tube, is frictionally secured to the projecting end thereof, and at its other end engages in the outer coupling part at a distance from the radial spring element in such a way as to rotate solidly with the outer coupling part.

    The closest to the proposed technical essence and the achieved effect is a shaft coupling 5 containing two half-couplings covering one another, connected by flat springs made with torsion elements at one end and placed in radially arranged ka-1® measures filled with liquid [1] .
    A disadvantage of the known clutch is the low energy consumption and smoothness of the moment transmission associated with the short length of the torsion bars and large 15 stiffness.
    The aim of the invention is to increase the reliability and smoothness of the transmission of torque.
    To achieve this goal, a coupling for connecting shafts, comprising two half-couplings with hubs, connected by flat steel radial springs placed in radially arranged chambers made in the outer half-clutch, filled with fluid and hydraulically interconnected, as well as torsion spring elements in in the form of bushings and rods connected at one end to the end of each radial spring, and at the other end to the outer coupling half, provided with additional torsion elements and a sleeve formed 'integrally with the radial springs located on the end of the sleeve, each rod is located in the sleeve and zhertko connected thereto at one end and the other end of the rod is rigidly connected to the female coupling half.
    The length of the sleeve section from the location of the radial spring to its free end is more than half the entire length of the sleeve.
    The coupling is provided with rings with teeth on the inner surface, covering the hubs of the coupling halves, made with teeth on the outer surface.
    In addition, the coupling is equipped with a centering sleeve, and each half-coupling is made of two coaxial parts mounted on the sleeve and interconnected, while the torsion bushings with the rods of one part of the half coupling are located between the torsion sleeves with the rods of the other part of the half coupling.

    Aa on the FIG. 2; on the FIG. 2 - section Bgb on the FIG. 1; on the FIG. 3 - section Bb on the FIG. 4;. on the FIG. 4 - section Gg on the FIG. 3; on the FIG. 5 - view of D on figs • 3 *
    The coupling consists of a coupling half 1 and a coupling coupling 2 enclosing it. Half coupling 1 is made with a pin 3,. on which the flange 4 of the half coupling 2 is mounted. The disk 5 is fastened to the flange 4 of the half coupling 2. The ends of the radially spaced flat springs 7, made in one piece with the torsion bushings 8, are mounted in the grooves b made in the axle 3.
    The bushings 8 pass through the holes 9 0 with the possibility of rotation. Each torsion sleeve 8 includes a torsion bar 10, which is rigidly connected to the disk 5 and to the sleeve 8. A rigid connection of the rod 10 and the sleeve 8 can be carried out using the shrink ring 11, and the disk 5 and the rod 10 - using the hole 12. In the flange 4 is made of a cavity separated by springs 7 into two radially spaced chambers 13 and 14, filled with liquid. The coupling is equipped with rings 15 and 16, made with teeth on the inner surface, covering the hubs of the coupling halves 1 and 2, made with the outer teeth 17 and 18.
    The coupling made of two parts (Fig. 3) consists of half-couplings and 20 connected by springs 7, torsion sleeves .8 and rods 10 located in the detecting parts 21 and 22, rigidly interconnected by means of flanges. The chambers with the fluid 13 and 14 in parts 21 and 22 are separated from each other by a disk 23 covering the chambers. The coupling halves 19 are mounted rotatably on the sleeve 24. As can be seen from FIG. 5, torsion sleeves with rods of one part of the coupling halves are located between the torsion elements of the other part.
    The coupling operates as follows. When the moment is transmitted between the half-couplings (α-α lines in Figs. 1 and 3), the bends of the springs 7 and the torsion of the bushings 8 and the rods 9 are sequentially deformable. An increase in the total length of the torsion elements increases the elasticity of the coupling and the smoothness of the transmission of torque without increasing the axial dimensions of the coupling . The energy intensity of the clutch also increases.
    The flow of fluid from the chamber 13 into the chamber 14 and vice versa provides damping.
    In a two-part clutch, an increase in the total length of the torsion elements and an increase in elasticity are achieved compared to a simple clutch. The coupling of the half couplings by means of teeth 17 and 18 with rings 15 and 16 provides compensation for axial 5 'displacements.
    The use of the coupling makes it possible to increase the fatigue strength of the connected shafts when transmitting variable torques, for example, in diesel engines.

     The invention relates to mechanical engineering. Closest to the proposed technical essence and achievable effect is a shaft coupling containing two female half-couplings, connected by flat springs made with 3 torsion elements at one end and placed in radially filled chambers filled with liquid 1. A disadvantage of the known coupling is the low power consumption and smoothness of the transmission of the moment, associated with the small length of the torsion bars and high rigidity. The aim of the invention is to improve the reliability and smoothness of the transmission of torque. .. To achieve this goal, a coupling for connecting the shafts, comprising two coupling halves with hubs and one that wrap around each other, connected by flat steel radial springs placed in radially arranged chambers filled with fluid and hydraulically connected to the outer coupling half and torsion spring elements in the form of sleeves and rods, connected at one end with the end of each radial spring, and at the other end - with the outer coupling half, are equipped with additional torsion or elec cients and sleeve are integrally formed with the radial springs located on the end of the sleeve, each rod is located in the sleeve and zhertko soedtsgnen with it at one end and the other end of the rod is rigidly connected to the floor covering uftoy. The length of the section of the sleeve from the location of the radial spring to its free end is more than half the entire length of the sleeve. The clutch is provided with ringed with teeth on the inner surface, covering the hub half couplings, made with teeth on the outer surface. In addition, the coupling is provided with a centrifugal sleeve, and each coupling half is made of two coaxial parts mounted on the sleeve and interconnected, with the torsion ones. The bushings with the rods of one part of the half-coupling are located between the torsion bushes with the rods of the other part of the half-coupling. The clutch can be equipped with a disk located between two parts of the coupling half and closing the chamber. FIG. 1 shows a coupling, a slit 2; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - section of bgb in fig 4 - section 4g. in fig. Bb in Fig 3; in fig. 5 is a bottom view of the GGD of FIG. 3. The coupling consists of half coupling 1 and half coupling half surrounding it. Half coupling 1 is made with a trunnion 3, on which flange 4 is mounted. Half coupling 2. With a flange 4 of half coupling 2, a disk 5 is fastened in grooves b made in axle 3, the ends are radially mounted arranged flat springs 7, made in one piece with the torque bushings 8. The sleeves 8 pass through the holes 9 with the possibility of rotation. Each torsion bushing 8 includes a torsion rod 10 rigidly connected to the disk 5 and to the sleeve 8. The rigid connection of the rod 10 and the sleeve 8 can be made using the shrink ring 11, and the disk 5 and the rod 10 - through the hole 12. In The flange 4 has cavities separated by springs 7 into two radially spaced chambers 13 and 14 filled with liquid. The coupling is provided with rings 15 and 16, made with teeth on the inner surface, covering the hubs of coupling half and 1, made with external teeth 17 and 18.

The chambers with liquid 13 and 14 in parts 21 and 22 are separated from each other by a disk 23 covering the chambers. The half couplings 19 and 20 are rotatably mounted on the sleeve 24. As can be seen from FIG. 5, the torsion bushes with the rods of one part of the half couplings are located between the torsion elements of the other part. The clutch works as follows. When the moment is transmitted between the coupling halves (lines a-a in Figs. 1 and 3), the bending of the springs 7 and the torsion of the sleeves 8 and rods 9 is consistently increased. The total length of the torsion elements increases the elasticity of the coupling and the smoothness of the moment without increasing the axle size of the coupling. The power consumption of the coupling also increases. The flow of fluid from chamber 1 into chamber 14 and vice versa provides damping. In a clutch consisting of two parts, an increase in the total length of the Orsion elements and an increase in elasticity are achieved as compared with a simple UFT.
