AI Technical Summary
Traditional diaphragm couplings have high stiffness, making them difficult to adapt to working conditions with large axial displacements, resulting in limited deformation and short service life.
A double-diaphragm rivet clamping coupling is designed. By setting hollow grooves on the diaphragm and adopting an arc-shaped protrusion structure, the rigidity of the diaphragm is reduced, the elastic deformation capacity is enhanced, and it can adapt to large axial displacement. Furthermore, the force is evenly distributed through the cross-shaped protrusion fixing points, which improves the degree of freedom of deformation.
It improves the axial compensation range of the diaphragm, reduces the risk of fatigue fracture, extends service life, and enhances the deformation compensation effect of the diaphragm.
