UGears STEM Lab: Gearbox

Learn how the manual GEARBOX works:

The Gearbox is a stylized educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working. A mechanical gearbox is a reducer that provides speed and torque conversions from a motor to the driving wheels. After assembly, you can experiment with the  Ugears manual Gearbox, by turns, choose I, II, III, or reverse with a kinematic pair of gears with different ratios and, rotating the actuator handle clock-wise, you can watch and control the rotation speed of the lay-shaft and drive shaft. In a Position “N” – idle in which both clutch gears of lay-shaft remain uncoupled and idling; the First Gear makes the lay-shaft and gears rotate with the lowest speed;  the Second Gear lets the drive shaft along with the flywheel rotate with an average speed and the Third Gear allows the lay-shaft and all gears rotate with the highest speed. Switch on the Reverse gear and see how the driving clutch gear moves to the left towards gear “R” and connects to it transferring the rotation to the lower gear arrangement and propelling the lay-shaft and all gears to rotate in reverse.
