"elecon" has developed a custom built three stage, helical reduction gear box with pinion stand having vertical input as well as output shafts. The pinion stand has centre distance of 560 mm. This is in operation at m/s usha martine industries ltd., jamshedpur.
Teeth of pinion, wheel and pinion stand pinions are made from high tensile carburising alloy steel, 17crnimo6 as per din 17210- case hardened mild steel fabricated construction of fe410wa as per is 2062.
The shafts are supported on anti-friction special roller bearings of adequate size to take care of radial and axial loads permitting large degree of freedom against misalignment.
The gear box is equipped with forced feed lubrication system for providing necessary amount of oil to various gear meshes and bearings thereby resulting in smooth and trouble free operation.
