Planetary carrier for Demag AC-395

The planetary carrier 76306073 functions as a structural housing within the final drive transmission of heavy machinery. It holds the satellite gears in position, allowing them to rotate around the central sun gear. This mechanism enables significant speed reduction and torque multiplication within a compact assembly, which is necessary for the drive systems of mobile cranes. By maintaining the alignment of the planetary gears, the carrier ensures that rotational force is transmitted effectively through the drivetrain to the wheels or winches.

This component is compatible with Demag AC-395 models, including the AC-395 Serie-76011 U150. It is engineered to meet the specific dimensional requirements of these crane transmissions to ensure proper gear meshing and smooth operation. The carrier is a critical part of the drivetrain, responsible for supporting the mechanical loads generated during travel and lifting operations.

In planetary gear systems, the carrier acts as the output or reaction member depending on the configuration. It distributes the input torque across multiple planet gears, which balances the load and reduces stress on individual gear teeth. Proper maintenance of the surrounding lubrication and regular inspection of the gear assembly help preserve the alignment and function of the carrier within the transmission system.
