Embodiment
As in Fig. 1-Fig. 3, a kind of Combined coupler, comprises shaft coupling piece 1, is connected between shaft coupling piece 1 by combined elastic module 2, elastomeric deformable module 13 or metallic elastic module 6 that thickness size is identical.Structure thus, the present invention goes for various different operating mode, such as the deformability of elastomeric deformable module 13 is stronger, and the rigidity of metallic elastic module 6 is comparatively strong, larger moment of torsion can be transmitted, and combined elastic module 2 merges the feature of the two, because three is completely the same on thickness size, therefore can change according to operating mode or select different structures, this be for test type, and such as Machine Design producer is especially effective.
In described elastomeric deformable module 13, connected by flexible elastomer 3 between elastomer mounting plate.The elastomer mounting plate of machine shaping is integrally formed with flexible elastomer 3 by sulfurization technology, flexible elastomer 3 herein adopts rubber usually, elastomer mounting plate is then connected with shaft coupling piece 1 by bolt, and shaft coupling piece 1 is connected with driving shaft or driven shaft with key by keyway 5.In this structure, elasticity is comparatively large, can compensate assembly error, and effectively can reduce stress alternation in the process of transmitting torque.
In described metallic elastic module 6, connected by multiple metal spring piece 4 between metal spring piece mounting plate.
As in Fig. 4, described metal spring piece mounting plate is provided with multiple connecting through hole 7, and one end that connecting through hole 7 coordinates with metal spring piece 4 is provided with curve bath 8, and the other end is provided with conical section 9;
As in Fig. 5, described metal spring piece 4 one end is provided with the second arc shaped surface 12 coordinated with curve bath 8, and the other end is provided with stop collar 14 by pin 10, and stop collar 14 is provided with the first arc shaped surface 11 coordinated with curve bath 8.Adopt this structure to make up nonmetal, such as rubber material affects larger deficiency by outside climatic, thus improves the maintainalbility energy of coupling.Adopt this structure, metal spring piece 4 can tilt and bend in connecting through hole 7 centered by axis, and still keeps reliably stressed, thus can compensate axis and the radial error of driving shaft and driven shaft.And this structure can, according to the requirement of actual applying working condition, select the resilient metal member 4 of varying number or different-stiffness and intensity to form, to adapt to Practical Project demand, this coupling also can play the protective action of mechanism's overload simultaneously.
The revolution bus of described conical section 9 is curve.Adopt this structure, the revolution bus of conical section 9 and the metal spring piece 4 after being out of shape better are fitted, and avoid forming partial cut to metal spring piece 4, cause stress to concentrate.
