Which item is a component of the worm gear assembly?

• A. Spacer
• B. Filament
• C. Speed reducer pulley
• D. Gear

Answer: (C)

Understanding how a worm gear assembly achieves speed reduction helps. A speed reducer pulley provides the belt-driven interface that transfers power from the motor to the worm gear while delivering the designed reduction in speed. This makes it a fundamental component of that assembly because it enables the belt to transmit torque and set the overall reduction ratio. A spacer is mainly for positioning and spacing, not driving motion; a filament has no role in this mechanical setup; and while a gear (the worm wheel) is part of the worm gear system, the pulley specifically enables the drive link and speed reduction through the belt drive.
