EASY TO PRINT: Educational 4:1 Gear Ratio Example

thingiverse

This is a simple, easy to print model of gear ratios. There is a stand for the gears, three gears with diameters of 2.5, 5 and 10 centimeters included in the file location. Giving gear ratios of 2:2:1 When assembled these objects have a 4:1 gear ratio. This meaning that for every time the small 2.5cm gear turns four times, the large 10cm gear turns once. Other properties of gears can be observed using this assembly. For example, only the beginning and final gear affect ratio. Despite this, intermediate gears (the 5cm gear in this case) can serve some purpose. Note how the small and large gear both rotate in the same direction, whilst the middle gear rotates in the opposite direction. Other applications of intermediate gears include reducing torque and transnational loads on the beginning and final gears. Meshing of gears such as in this model are used to convert speed to the rotational motion known as torque. An application in the real world could be in an electronic linear actuator often used on smaller backhoes to move to move the arm.
