Ugears STEM Lab Variator

The Variator is a device that transmits and adjusts the engine torque by changing the gear ratio. The gear ratio can be changed automatically, manually or within a preset program.
 
With the Ugears Variator model from the STEM lab collection, you will learn to understand one of the most important parts of a car without getting your hands dirty with engine oil! The variator is used in mechanisms, where a continuous range of gear ratios must be changed seamlessly: cars, scooters, snowmobiles, conveyor belts, metal cutting machines, etc.
 
To have a better idea about how it is used in different types of equipment, try the AR application that comes with the Ugears STEM model.
 
The design of the Variator and how it works
The mechanical variator from the Ugears STEM lab collection is a fully functional wooden replica of a belt-driven Friction Cone CVT. The Cone CVT varies the drive ratio by moving a wheel or belt up and down the axis of the tapered roller. In the Ugears Variator model, the belt, manually driven via the reducer, transmits the rotation to the driven cone pulleys. Use the transmission fork to change gears and watch the driven cone pulley speed decrease or increase while the drive cone pulley speed remains the same. The open design of the model allows you to see the complete operation.
 
The STEM Lab collection is intended to introduce children to science in a playful way. All products from the STEM Lab collection are therefore very educational and contribute to de development of your children.
