SAMIFLEX ELASTIC COUPLINGS

SAMIFLEX ELASTOMERIC COUPLINGS Now there' s a new solution to one of the most costly and troublesome problems facing maintenance personnel - coupling failure and the expensive down time associated with fixing it. Only four parts to the Samiflex Coupling The two identical hubs ( items A & B) are manufactured in cast iron, cast steel or aluminium alloy and incorporate four, six or eight teeth, depending on size rating of the coupling. A precision cast and machined polyurethane insert ( item C) fits between the hubs and is split axially so fitting and removal can be achieved without moving hubs.The holding ring, manufactured in steel, polyamide or bronze ( item D) is fitted over the insert securing both insert and ring between hubs. The coupling requires no bolts or nuts. ATEX Approval The range of Samiflex Couplings has been approved under ATEX directive 94/ 9/ EC - for use in potentially explosive atmospheres. Features and Benefits • Coupling insert removable without the need to remove either driving or driven equipment. • Change out of coupling insert is faster than any other coupling. • No lubrication or maintenance required over the life of the insert. • The polyurethane insert can be supplied in a variety of hardnesses to optimise torque capacity and damping. • Polyurethane insert is very resistant to chemical attack. • Standard insert can handle large temperature range from -40 to 80 ° C. • High temperature insert available up to 150 ° C. • Hubs can be rotated independently during motor test. • No metal to metal contact • Large bore to torque capacity • Vertical operation possible with standard coupling. • Retaining rings provided with locking screws as standard. The specification contained within this brochure are correct at time of going to print. Autogard are continually reviewing and updating the specifications on all its product range and therefore reserve the right to change any detail. Assembly & Disassembly Once hubs ( A) and ( B) and holding ring ( D) have been installed and aligned on the shafts the coupling hubs will not have to be moved again during the life of the equipment.The elastic insert ( C) can then be installed between the parallel slots formed by the hub teeth. With the insert in position, slide the retaining ring ( D) into position over the polyurethane insert. Centrifugal force will expand the insert under operation ensuring a tight, secure fit inside the retaining ring. Removing and replacing the coupling insert is very simple and requires no special tools. By removing the retaining ring, the insert can be quickly and easily removed and replaced without the need to undo screws, bolts or other fasteners.
