Which component is a part of the worm gear assembly?

• A. Piston
• B. Flywheel
• C. Crankshaft
• D. Speed reducer

Answer: (D)

Worm gear assemblies are used to achieve a large reduction in speed while increasing torque by meshing a screw-like worm with a wheel. The component that best fits this context is the speed reducer, since the whole purpose of a worm gear setup is to reduce rotational speed. Pistons are associated with converting linear motion in engines, flywheels store rotational energy, and crankshafts convert reciprocating motion to rotation. None of these describe the worm gear’s primary function, whereas a speed reducer directly embodies what the worm gear accomplishes.
