OF THE FUTURE
Material of the present and the future
In recent years, the demands in gear manufacturing have increased significantly in terms of competitiveness and cost reduction. Gears must be more robust, powerful, compact, cost-efficient, and above all lighter. This brings aluminum to the forefront as the preferred material, since it is significantly lighter than steel. Weight means cost—especially when gears must be moved during operation.
Every gram counts
Unnecessary weight in the gearboxes of vehicles like cars, construction and agricultural machines, cranes, or ships leads to additional energy consumption. This is where aluminum stands out: with a specific weight of around one-third of that of steel, gearboxes made of an aluminum casting are lighter and save a great deal of energy.
Gear housings typically generate a lot of heat that must be dissipated. Since aluminum has excellent thermal conductivity, aluminum cast gear housings can efficiently and rapidly transfer internal heat to the surroundings. Through the casting process, additional cooling fins can be integrated into the housing to enhance the cooling effect.
