ROMA make GEARFLEX Gear Toothed Flexible Coupling offer most reliable and positive means of transmitting

mechanical power with ample flexibility to combat various forms of misalignment: angular, offset and combination of angular offset including end float of shafts.

ROMA make GEARFLEX standard double engagement type gear toothed flexible coupling consists of two gear hubs, two outer flanged geared sleeves, a set of bolts, grease nipples and O rings. The external teeth of the hubs engage with the internal teeth of sleeves are bolted together thus making the unit a complete coupling.

The flexibility in the coupling is provided by specially designed gear teeth configuration which makes the coupling self-aligning duration operation.

The geared hubs are made out of tested forged steel and flanged geared sleeves are made out of tested forged steel or graded cast steel depending on the size and requirements. The teeth are generated and are involute from. The bolts are made out of high tensile steel and precision machined. The O rings are made out of specially bonded rubber to withstand compression and of adequate hardness for a long life.

The sleeves and hubs are heat treated to hardness of 240-280 BHN to provide wear-resistance properties for longer life of the couplings.

For standard ROMA make GEARFLEX couplings the lubrication is provided by Grease which penetrates the tooth contact area to form a thin layer of lubricant to minimize the friction. The grease is injected through grease nipples and is retained by O rings provided on both sides.

OPTIONAL SEALING: On specific request, ROMA make GEARFLEX couplings are provided with alternative sealing like felt seals, oil seals, detachable sealing arrangement with or without pressure plate etc.

OIL LUBRICATION: In case of lubrication by oil, the Couplings are provided with Oil-Plugs.
