Which of the following is not one of the three basic components of a gear drive system?

Explanation:
In a gear drive system, motion is transmitted through meshing gears, with three basic elements: the driver gear that provides input motion, the driven gear that receives output motion, and often an idler gear that changes direction or spacing without altering the gear ratio. A belt belongs to belt drive systems, not gear drives, since it uses a belt and pulleys instead of interlocking gear teeth to transfer motion. The other components listed—driver gear, driven gear, and idler gear—are the core parts that define a gear transmission, while a belt is outside that category.
