Key Features of Helical Gear Boxes

• Gears and pinions: The gears are generated with highest Accuracy on hobbing machine. The material for the pinion and Gear wheel are made of hard wearing special steel of graded strength to meet the individual load conditions. The selection of module, foot profile, and material is made in conformity with speeds, ration, and load conditions to give maximum tooth contact and overlap, thus ensuring most favourable meshing and soundless running.
• Shafts: Shafts having pinions cut integral are of heat treated alloy steel bars or alloy steel forging. All other shafts are of heat-treated carbon steel and are finished to high precision tolerance by grinding.
• Bearings: Anti-friction bearings of ample size are used throughout to ensure long service life. The use of antifriction bearings ensures high efficiency, correct centre distance and proper shaft alignment. Shaft extensions are fitted with high quality seals to prevent oil leakage and dust entry.
• Lubrication: For Normal speeds, splash lubrication is provided by gears dipping in oil. The oil level indicator located in the housing is to ensure a proper amount of lubricant in the housing.
• Cooling: The heat generated within the gear units is dissipated by a sufficiently large surfaced area of the housing for higher capacities additional cooling is provided by fans, cooling inside lower housing depending on heat dissipation requirement based on power to be transmitted and ambient temperature.
