Spur Gear Lifting Apparatus

The model is intended for wall mounting. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. With straightforward experiments, the torque conversion in gear wheel pairs and the efficiency of a gear unit are investigated. The mechanism demonstrates the relationship between the ratio of the number of teeth on spur gears and the transmission ratio of gears.
