Worm Gear Drive Mechanical Demonstration Set

This mechanical demonstration model shows the fundamentals of how a worm gear drive works. The system features a hand crank that drives the worm gear mechanism, with a dial to show rotation. The unit is an open system sandwiched between two clear plastic plates, allowing students to observe the gear interaction during operation. Constructed with heavy-duty metal and plastic components, the model is a bench-top or desk-top item suitable for classroom demonstrations of mechanical advantage, gear ratios, and power transmission principles.
