The Variator is a mechanism which adjusts the force of the engine by alternating the gears ratio. Most drivers and car enthusiasts are familiar with CVT (Continuously Variable Transmission). The Ugears Variator STEM lab model embodies this key part of an automobile, so there is no need to get your hands dirty in order to grasp the principle!

In 1879 Milton Othello Reeves, a prominent US businessman, came up with a mechanism for sawmills. Later this transmission got fitted to car engines. Now the CVT is used in a variety of machines requiring a smooth changing of gear ratios. These include cars, motorboats, quad bikes, conveyor belts and many more.

How Ugears STEM lab Variator Works

The Ugears STEM lab Variator is a completely functional wooden copy of a Belt-driven Friction Cone CVT. The drive ratio is varied by moving the belt or wheel up and down the axis of a conical roller. The belt is powered manually with the help of the reducer. The rotation is then transferred to the cone pulleys. Change the gears with the help of the transmission fork and see how the driven cone pulley speed increases or decreases while the drive cone pulley’s speed stays unchanged. Because of the model’s open design, the whole process is visible in order to satisfy an inquisitive mind!

    I would recommend this to a friend!
    I have built several U-Gears model (6 to date)and enjoyed every moment with them. I found that it is vital to follow instructions carefully to have the final product working as expected. I am anxious to begin on my next kit.

    I would recommend this to a friend!
    I got this as a gift, but didn\'t expect much, since I had tried a competitor model once and it didn\'t work properly. Not so with Ugears! Everything fitted brilliantly, no complaints whatsoever. My variator rocks!
