The difference with the plum flexible couplig :
Resilient coupling with spider are sometimes mistaken for plum flexible couplings, and their appearance is almost similar after installation.But under the same model, the torsion force of the Resilient coupling withs spider is greater. Compared with the plum blossom flexible coupling, its inner hole and shape can be made smaller.
1 Compact size and low inertia.
2 Use engineering plastics as elastic components, which are buffered, damped, and durable. The working temperature from -35 to + 80 °C and maintenance-free. It allowable speed can reach to 19000 rpm,so it famous for high speed jaw coupling.While ite nominal torque is not very low,the maximum torque up to 18650N.M.so some time we call it high torque jaw coupling
3 The elastic body is restricted by the convex claw block, which can avoid internal deformation, due to impact and external deformation will centrifugal force. The large concave surface of the convex claw makes the surface pressure on the involute gear small. Even if the gear are overloaded, the gear will not abraded or deform.
4 Nominal torque is the value when the elastomer is 92shA. When using 98hA, the torque will increase 70%.
5 Axial plug-in assembly, easy to installation, save time; small size, small movement inertia, maintenance-free; easy visual inspection.
6 The intermediate elastomer is made of German-made polyurethane material, which has a variety of hardness to choose .
no backlash connection under prestress, used for spindle drive, lifting platform and machine tool
