Definitions:

Planetary Carrier

A component within a planetary gear system that holds one or more gears in place as they orbit the central sun gear, distributing torque and rotation.

Planetary Pinions

Gears that orbit around a central gear in an automatic transmission or differential, typically found in complex machinery to achieve various gear ratios.

Torque Load

The force of rotating objects applied at a distance from the object's axis, creating rotational motion or resistance.

Multiple Disc Clutches

Clutch systems that use several discs and plates, providing higher torque transmission and smoother engagement, commonly seen in heavy machinery and performance vehicles.
