SAMIFLX LASTIC COUPLING The new SAMIFLX elastic coupling is the result of the experience and development of the last twenty seven years of involvement in all industrial sectors. The new SAMIFLX couplings are characterized by: 1. The option of attaching the ring to the elastic insert to prevent it moving axially. 2. The option of working vertically, using the standard retaining ring and the new design of elastic insert. 3. xpansion of the range of polyurethane elastic inserts, colour coded according to characteristic and performance. We would highlight the high performance elastic insert, with which we have increased the torque rating by 4%. 4. 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. 5. Increase of the performance, with the incorporation of the new models A45, A55 and A.. xpansion 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. DSCRIPTION There are only four parts to SAMIFLX 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 A and A, 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 a mating holes in the elastic insert and once secured ensures that the ring can not move during operation (see. fig. 3). ASSMBLY AND DISASSMBLY After machining the bores, the hubs (1) and (2) are fitted onto the shafts. Note, the retaining ring should be located over the shaft prior to setting the DBS (Distance Between Shaft nds) and aligning. The teeth of the hubs are positioned facing each other, to the correct gap (). The elastic insert (3) can then be installed in the slots formed by the parallel teeth. When the insert is in position, slide the ring (4) onto the polyurethane insert, tapping gently into place with soft-headed hammer, until the ring s inner pin falls into place in center hole of insert. Centrifugal force will expand the elastic insert to fix it tightly to the inside of the ring. If the alignment cannot be kept within the admissible tolerance, the ring can be secured using locking set screws (fig. 3). To disassemble, remove the ring. The insert can then be quickly and easily removed and replaced. No special tools, screws, bolts or other fasteners are needed.

FATURS AND BNFITS Assembly and disassembly of the elastic insert without having to displace the motor or the unit being driven. This advantage permits the inspection of the insert at any time without a lengthy shut-down. Simply displace (move to one side) the ring, remove the insert, inspect and if necessary replace with a new one. All this takes a few minutes. The two hubs works independently as the coupling transmits torque. This concept allows free-wheeling of the motor or driving unit in the system by simply moving the ring and removing the insert. This is specially helpful when the driving unit is a combustion engine and it becomes necessary to repair or test the engine without any load. As the hubs are independent of each other, if the insert ruptures or breaks, there is no metal to metal contact creating any spark thus enhancing the explosion proof properties of the coupling. The polyurethane insert is a key part of the coupling and is made of a very special elastomer compound. Its estimated average lifetime is 25, hours work under normal conditions. The coupling is easily aligned without expensive tools or measuring devices (see our installation instructions). Fig. 3. 3

INSTRUCTIONS FOR ASSMBLY OF SAMIFLX COUPLINGS 1. POSITIONING OF TH PARTS OF TH COUPLING. Standard coupling hubs, (type A+C) can be positioned on either shaft alike. We recommend putting the flange hub over the drive shaft in couplings with spacer. For couplings with a brakewheel or brakedisc, we recommend putting the hub which houses the wheel or disc, over the shaft of the machine driven. The couplings hubs are supplied pilot bore. Upon request, we supply the hubs finished bore to ISO tolerances and keyways as per DIN 5 Standard. The dynamic balancing of the coupling is made along two planes, quality G,3 as per VDI 2. The balance is made in couplings with finished bore, and indication must be given as to whether it should be made with or without a keyway. 2. RING ASSMBLY WITH LOCKING ST SCRWS. With the purpose of keeping the alignment within the maximum admissible tolerances, and in order to prevent the ring slipping axially, it must be fixed to the elastic insert using two set screws inserted through two tapped holes in the retaining ring. LOCKING ST SCRWS DIMNSIONS FOR RTAINING RINGS Type A A A1 A2 A3 A4 A45 A5 A55 A A7 A A9 A1 A DIN913 M5 M M M M1 M1 M1 M1 M1 M M M M Length 1 1 1 1 1 3. ASSMBLY AND START-UP For assembly and start-up of the Samiflex couplings, please follow our installation instructions in our bulletin, 152/97. For ATX requirements, please follow our bulleting 7/23. 4. SAFTY PROCDURS The equipment (motor) must not be started up until the holding ring has been assembled and secured with the locking set screws to the elastic insert. The elastic insert is projected outwards from the hubs if the equipment (motor) is started up without the holding ring having first been assembled and secured. Coupling guards should be installed prior to start-up. All rotating equipments are potentially dangerous and can cause serious injury. They must be properly guarded in compliance with standards for the speed and applications in which they are used. It is the responsibility of the user to provide proper guarding accordance with regulations.
