• Specification

• Function

1.Central Power Transfer Node:

In a planetary gear configuration, the sun gear is the central, typically smaller gear around which planet gears rotate and mesh. As "Sun Gear No.2," it acts as a critical link in transferring rotational power—either receiving input from a driving source (e.g., an engine or motor) or delivering output to subsequent components. Its meshing with planet gears ensures efficient energy transfer through the system.

2.Modulation of Speed and Torque:
By interacting with planet gears (which also mesh with an outer ring gear), Sun Gear No.2 enables precise adjustment of speed and torque ratios. Depending on the system’s configuration (e.g., whether the sun gear is driven, locked, or allowed to rotate freely), it can either increase torque (for heavy loads) or boost speed (for efficiency). This adaptability is vital for machinery operating under varying conditions (e.g., digging vs. traveling).
