Planet carrier (also known as planet wheel carrier or planet wheel bracket) is the core load-bearing and moving component in a planetary gear transmission mechanism. It is not a simple bracket but a precise dynamic structural part that withstands complex loads. Its main functions are:
Support and positioning: Accurately fix the axial positions of multiple planet gears, ensuring all planet gears revolve around the sun gear and maintain a constant meshing relationship with the internal ring gear.
Transmit torque and motion: As an input or output end, transmit torque and rotational motion to the planet gear shafts (and then to the planet gears), or receive torque and motion from the planet gear shafts.
Withstand complex loads: During operation, bear the meshing forces from the planet gears (radial force, tangential force), centrifugal force, and bending and torsional stresses generated by transmitted torque.
Ensure load sharing: The rigidity and manufacturing accuracy of its structure directly affect the **uniform load distribution** among multiple planet gears, which is crucial for the transmission system's load capacity, smoothness, and service life.
Provide bearing mounting positions: Usually designed with structures to install supporting bearings (such as deep groove ball bearings, tapered roller bearings, sliding bearings), ensuring stable rotation relative to the transmission housing.
