ROTOFLEX Curved Tooth Flexible Gear Couplings are unique of its kind in the field of mechanical power transmission. These gear couplings have outstanding features like mechanical flexibility and compensation of misalignment (angular, parallel and axial) of the connected shafts. These can used extensively in various industries like rolling mills, cranes, cement plants, dredgers, conveyors and elevators, rubber & plastic industries, compressors, fans, blowers, and in many other industries. These couplings consist of to halves with internal teeth having curved/ crowned shape & two outer sleeves with internal spur teeth. Thus coupling ensures a greater flexibility because of its well designed tooth profile which allows a maximum area of contact between the external and internal teeth under any misaligned condition. Special ‘O’ rings have been provided at the end of the coupling hubs to prevent any leakage of the lubricant and entry of dust inside the coupling.
Up to size FGC - 03 both hubs and casings are made of steel confirming to 45C - 8 of IS : 1570. From size FGC - 04 casings are made of cast steel confirming to 23 - 45 of IS : 1030. Teeth of the couplings are heat treated to a hardness of HB 240 - 280. Bolts are also made of steel confirming to 45C - 8 of IS : 1570.
