The Bevel Helical Gearbox Housing is usually made of Close Grain Cast Iron. Sometimes Housing is also offered in Structural Steel when the application demands. They are rugged, corrosion resistant and absorb shock and vibration. The Helical Pinion is made of EN 353 Case Hardening Steel, Helical Gears are made of SAE 8620 Case Hardening Steel. The teeth are generated on Gear Hobbing Machine. They are then Case carburized, Hardened and Tempered. Finally, they are surface ground to close tolerances. The teeth Flanks are ground on Teeth Profile Grinder. This leads to very good efficiency and a quiet working condition. The Output shafts are from alloy steel forging or bars. Low speed shafts can be solid or hollow type. Bearings are fitted on a accurately bored journal and taper roller Bearings are used.
