Component Specifications

Definition
Planet gear pins/shafts are critical rotating components in planetary gear carriers that serve as mounting points for planet gears. They provide precise radial positioning, rotational support, and torque transfer between the sun gear and ring gear. These shafts must maintain exact alignment under high cyclic loading while minimizing friction and wear in the gear mesh interface.
Working Principle
These shafts rotate within the planet carrier assembly, transmitting torque from the sun gear through the planet gears to the ring gear. They function as both load-bearing axles and torque-transmitting elements, with their precise geometry ensuring proper gear meshing and load distribution across multiple planet gears for balanced power transmission.
Materials
Typically manufactured from case-hardened alloy steels (e.g., AISI 8620, 4140, or 4340) with surface hardness of 58-62 HRC and core toughness of 30-40 HRC. High-performance applications may use carburized steels, nitrided alloys, or specialized bearing steels with corrosion-resistant coatings.
