• Specification

1.Structural Support for Planet Gears:
The planetary carrier serves as a rigid framework that houses and supports the planet gears (smaller gears that orbit around a central "sun gear"). It holds the planet gears in position via shafts or pins, ensuring they maintain proper alignment with both the sun gear (center) and the ring gear (outer toothed ring). This structural integrity is vital for efficient power transfer through the gear set.

2.Torque Transmission and Distribution:
As part of the planetary gear system, the carrier plays a key role in transmitting torque. Depending on the system’s configuration (e.g., whether the sun gear, ring gear, or carrier is fixed, driven, or acts as the output), the carrier distributes rotational force between the planet gears and other components. This distribution allows the system to multiply torque, adjust speed, or reverse direction—critical for adapting machinery performance to varying loads and operating conditions.
