Elecon Engineering Company Limited

lecon has successfully designed, manufactured and supplied speed change helical gear box to get four different output speed with the same input speed by shifting the gear arrangement through hand lever & pneumatically operated cylinder.

this gear box with special design so that the different output speed achieved by shifting the gear wheel on spline shaft.

the gears are made from high tensile carburizing alloy steel, 17crnimo6 as per din 17210, case hardened to 60±2hrc, precisely ground to accuracy class 6 as per din 3961-63. The output shaft is made from medium carbon steel ck 60n as per din 17200 of adequate size to withstand heavy load transmission for better rigidity without undue deflection

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.(scgb2)

the piercing mill is used to pierce out and roll the mother tube out of original billet. The single input, double output, two-stage gearbox drives this mill. This is a three metre tall and robust gearbox with a base of 2. 8/1. 4 meters and weighing around 18 tons.

the gears are made from high tensile carburizing alloy steel, 17 crnimo6 as per din 17210, case hardened to 60± 2hrc and finely ground to accuracy class 6 as per the din standard to give smooth and trouble free operation. Output shafts are made from medium carbon steel ck 60n as per din 17200 of adequate size to withstand heavy load transmission for better rigidity without undue deflection. Gears are integral with shaft/key fitted to shaft and are supported in antifriction spherical roller bearings of adequate size to give higher working life and to correct misalignment. Output shafts are also provided with spherical thrust bearings to tolerate axial thrust load in both the directions. Gears and bearings are housed in accurately machined and highly rigid/robust ms fabricated housing to give better performance against severe jerks and vibrations.

the assel mill reduces and finishes the originally rolled mother tube. The finished seamless pipes are used for the races of antifriction bearings or even for other engineering applications. A tall, gigantic, rugged gearbox, having single input and three output with several idlers, drives this mill. The assel mill gearbox is 5. 1 metres long and 2. 7 metres tall, weighing around 23 tons and capable of absorbing strong vibrations and shocks imparted by the tube rolling mill. The open aperture provided in the gearbox allows backward movement of hot working stock.

elecon” has developed and supplied custom built helical reduction gear box cum pinion stand for rolling mill & briddle drives for m/s tisco jamshedpur - crm project. The pickle line and tandem cold mill(pl-tcm) for cold rolling mill (crm) capacity of 1. 2952 million tonnes per year is done by m/s hitachi-japan.

teeth of pinion, wheel and pinion stand pinions are made from high tensile carburising alloy steel, 17crnimo6 as per din 17210-case hardened to 60+-2 hrc and precisely ground to class of accuracy 6 as per din 3961 - 63. Housing of mild steel welded construction, grade fe 410 wa as per is 2062 duly stress relieved.

the shafts are supported on anti-friction spherical roller bearings of adequate size to take care of radial and axial loads and housed in the specially developed eccentric bush permitting large degree of freedom against misalignment.

the gear box is equipped with oil flow, pressure and temp. Monitoring items. The gear units are connected with the centralized forced feed lubrication system for providing necessary amount of oil to various gear meshes and bearings thereby resulting into smooth and trouble free operation.
