Samiflex Elastic Coupling

The new Samiflex elastic couplings are characterised by options like: attaching the ring to the elastic insert to prevent it moving axially; working vertically, using the standard retaining ring and the new design of elastic insert; and expansion of the range of polyurethane elastic inserts, colour coded according to characteristic and performance. The high performance elastic insert has increased the torque rating by 40%. There is also limited end float coupling for all sleeve bearing motor applications. One of the major advantages of this coupling is that the standard hub can be easily modified for this requirement. Other benefits are: increase of the performance, with the incorporation of the new models A45, A55 and Al1; and expansion of the range of materials used in the standard design, incorporating high resistance aluminium alloy, stainless steel, high performance polyurethane, shock-resistant polyamide and carbon fibre composites. There are only four parts to Samiflex couplings. The two identical hubs (1) and (2) are made from high-strength cast iron, ductile iron, cast steel or aluminium alloy, each with eight teeth, (except for the AO and A00, which have six and four respectively). The elastic insert (3), which is made from a special polyurethane elastomer, fits between the hubs. The outer retaining ring (4) is made of steel or polyamide, with interior pins for adjusting this ring on the elastic insert. The ring also has two threaded holes, symmetrical to each other, through which two set screws can be fitted. The set screws are aligned to mating holes in the elastic insert and once secured ensures that the ring can not move during operation. The coupling is easily aligned without expensive tools or measuring devices.
