Sungear for Demag AC-395

The sungear 997217 acts as the central input gear within a planetary gear train, where it meshes with surrounding planetary gears to transmit power and torque. By serving as the core of this assembly, it enables the necessary speed reduction and torque increase required for the operation of heavy machinery systems. This component is specifically engineered for use in the Demag AC-395 all-terrain crane, where it is integrated into the gear systems responsible for wheel reduction, winches, and slewing mechanisms.

This part is compatible with the Demag AC-395, including the AC-395 Serie-76011 U150 and AC395 models. It is designed to meet the specific mechanical tolerances required for the planetary gear sets found in these cranes, ensuring proper engagement with the planet gears during load lifting and machine movement. Proper alignment and tooth engagement are necessary for the efficient transfer of power from the drive source to the output components of the transmission system.

In a planetary gear set, the sun gear is positioned at the center, with planet gears rotating around it. This configuration allows for compact power transmission, which is common in crane gearboxes and drive hubs. The sun gear receives input power and distributes it through the planet gears to the carrier or ring gear, depending on the specific gear ratio requirements of the machine.
