Planetary pinion for Demag AC-395

The planetary pinion, part number 997122, serves as a critical element within planetary gear sets. These systems are utilized in heavy machinery to achieve high gear reduction ratios and torque multiplication within a compact assembly. The pinion rotates around a central sun gear and inside an outer ring gear, distributing mechanical loads to transmit power efficiently through the crane drivetrain.

This component is designed for the Demag AC-395 all-terrain crane. Within this machine, planetary pinions are integrated into final drive reducers, hoist winches, and the superstructure swing mechanism. These pinions allow the drive motor to operate at efficient speeds while delivering the necessary torque to manage heavy lifting operations. The part is compatible with Demag AC-395, AC-395 Serie-76011 U150, and AC395 models.

Planetary gear systems rely on the precise interaction of these pinions to manage the rotational forces required for crane operation. By engaging with the sun and ring gears, the pinions ensure that power is transferred smoothly across the gear train, which is essential for the controlled movement and positioning of heavy loads during lifting or slewing tasks.
