Description:
The "Sun Gear No. 1" is a component within a planetary gear system, commonly found in automatic transmissions, differentials, and other mechanical assemblies that require precise torque and speed control. The sun gear is located at the center of the gear assembly and meshes with multiple planet gears arranged around it. When driven by the input shaft, the sun gear transfers power to the surrounding planetary gears, which, in turn, distribute the force to the ring gear or carrier, producing controlled output in terms of speed and torque.
