For the growing need of steel roling mills, Elecon has developed custom-made gearboxes to obtain variable speed of rolling mill to suit client’s requirements. Such special-purpose gearboxes have been supplied to Precision Equipments, Flat Products and to ultimate users such as Comet Steels, Sipta Steels, Nanded, and Him Ispat, Himachal Pradesh.

The gearboxes are designed fortransmitting 0-1000-1000-900 KW power at 0-350-1150-1250 input speed and speed change ratio of 1.0689/1 and 1.857/1. The speed changing is done by means of a shifter coupling provided on the input shaft through a lever arrangement which is hydraulically actuated.

The speed change gearbox is coupled to a D.C.motor through the geared coupling at input shaft, and the output shaft of the gear box is coupled with the main gearbox by geared coupling. The main gearbox is coupled to a rolling mill for coiler, uncoiler, rewinder, payoff, and decoiler.
