 Elecon
has developed as special prupose custom built gear box for Bridle Drive
and sheet Mill application. This has two input and two output shafts
having independent gear trains driving the output shaft in opposite
directions with variation in power input. The output shafts are connected
to the rolls which stretch the sheet metal before rolling as well as
after rolling.
Teeth of pinion and wheels are of double helical type
so as to nullify the axial thrust acting on respective shaft. The gears
are made from high tensile carburising alloy steel, 17CrNiMo6 as per
DIN-17210 case hardened to 60 ± 2HRC and precisely ground to
class of accuracy 6 as per DIN 3961 - 63.
The shafts are supported in Antifriction Spherical
Roller Bearings of adepquate size to take care of radial loads permitting
large degree of freedom against misalignment.
The gear box is installed with centralised lubrication
oil system for providing necessary amount of oil to various gear meshes
and bearings thereby resulting into smooth and trouble free operation.
