Ugears Gearbox Stem Lab

The gearbox is a stylized educational model, an interactive study guide to the mechanism only to learn the essence and principles of operation. A mechanical gearbox is a reduction gear that provides speed and torque conversions from an engine to the driven wheels.

After assembly, you can experiment with the UGears manual gearbox modeling package by taking turns selecting I, II, III or driving in reverse with kinetic pairs of gears with different ratios. By turning the control lever clockwise, you can view the rotation and control the speed of the between shaft and drive shaft. In a position “N” – idle with both clutch wheels of the intermediate shaft disengaged and stationary; first gear rotates the intermediate shaft and gears at the lowest speed; second gear rotates the drive shaft together with the flywheel at medium speed and third gear rotates the intermediate shaft and all gears at the highest speed. Engage the reverse gear and watch the drive clutch move to the left toward gear “R” and connect to it, transferring rotation to the lower gear and rotating the intermediate shaft and all gears backwards.

The invention of the gearbox is by the famous German engineer Karl Benz. A gearbox is primarily used in the automotive industry as part of a car’s transmission mechanism that transmits clutch from the engine shaft to the wheels.
