Form rounding at described dog side and inner side edge intersection.
Locate the arcuate structure to outer lug centered by the inner edge of described dog.
Both sides are formed with boss respectively to compensate off-centre, drift angle and axial displacement inside and outside described protruding lobe.
Described locking mechanism comprises T-slot and the lock bolt that is formed on the cylindrical body outer end, described T-slot comprises the straight trough that is communicated with side and the curve bath of through hole and setting vertically and intersects vertically with the curve bath center, be formed with counterbore and tapped hole on the body of described straight trough both sides respectively, described lock bolt passes counterbore and cooperates that with tapped hole axle is held tightly.
Described locking mechanism comprises the tapped hole that at least one runs through cylindrical body side and through hole and the dogbolt that mates with described tapped hole.
Compared with prior art, the beneficial effects of the utility model are:
Plum blossom elastic coupling flexible coupling of the present utility model has the high pass moment of torsion, and no back clearance can effectively absorb vibration, off-centre, drift angle.Installation and removal are convenient, and the life-span is long, the rounding structure of redesign elastomer and gripping sleeve, can reduce when assembling elastomeric damage, easier assembling makes the stability of coupling and intensity increase significantly, and makes the life-span of coupling prolong 1.5 times by this design.Be best suited for the coupling that lathe uses.

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 only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 1-4, the utility model first embodiment's quincunx elastic coupling flexible coupling comprises two gripping sleeves 1 and 1 elastomer 2, described gripping sleeve 1 comprises that the center is provided with the cylinder body 10 of axial hole, described cylinder body 10 outer ends form locking mechanism, the inner end face of described cylindrical body 10 is outer 3 dogs 13 that stretch out vertically, and described dog 13 and body 10 are integrally formed and evenly distribute and formed the gap before adjacent two dogs at the interior edge face upper edge of cylinder body circumference.Described elastomer 2 is the polyurethane material, and it comprises radially outer 6 the protruding lobes 21 that stretch out of disc-shaped body 20 and relative body 20, and described protruding the lobe 21 and ring that be distributed on body 20 integrally formed with body is on week.Wherein, produce unnecessary shearing force when reducing to assemble or when using elastomer caused damage, described dog 13 be top margin at the class trapezium structure of inboard, namely dog comprises inner edge, two sides and the outside that flushes with the body outer periphery in close axle center.The arcuate structure of locating to cave inward centered by the dual-side of described dog, locate outwards to be accordingly the drum type structure that arcuation is heaved simultaneously centered by the described protruding lobe, wherein, the interlaced setting of the dog of two gripping sleeves 1 and between dog, form the gap in use, disc-shaped body 20 on the elastomer is inserted between the interior edge face of two adjacent gripping sleeves, protruding lobe can be inserted in the gap between the dog matchingly, protruding lobe contacts with the formula cambered surface of dog side, improved the damage that shearing force that contact strength effectively avoids producing constitutes elastomer.
Simultaneously, form rounding at described dog dual-side and inner side edge intersection, adopt the circular arc transition structure to make the root of boss and protruding lobe remain with the gap, can effectively avoid the rotary course acceleration or the gripping sleeve boss causes protruding lobe root when turning to shear fracture.
Further, the inner edge of described dog also adopts to the arcuate structure of outer lug and to improve property is installed, and avoids the elastomeric breakage that causes in the installation process.
