The planet carrier holds and supports the planet gears, allowing them to rotate around the sun gear while maintaining proper alignment and spacing. It transmits torque and motion between input and output shafts in planetary gear systems.
Common materials include alloy steel, cast iron, and forged steel. The choice depends on required strength, weight, and cost.
Key parameters include rated torque, maximum speed, center distance, carrier outer diameter, thickness, tolerances, surface roughness, hardness, weight, operating temperature, and axial load capacity. These must be verified for the specific application.
Verify all specifications with the legal manufacturer or supplier. Check that the carrier's rated torque, speed, and load capacities align with your system's demands, and confirm compliance with relevant standards such as ISO 6336.
