The Variator is a device that transfers and regulates the torque of the engine by changing the ratio of the gears. The gear ratio can be changed automatically, manually or with a preset program. The term that drivers and car fans are most familiar with is Continuously Variable Transmission, or CVT. With the wooden Variator puzzle from the STEM lab collection, which you can assemble yourself, you will learn and understand one of the most important parts of a car without getting your hands dirty with engine oil!
Variable speed variable transmission is used in mechanisms where the gear ratio must be changed continuously without difficulty: cars, scooters, snowmobiles, pigs, transport vehicles, cutting machines, etc. To get a better idea of how it is used in various equipment, try the augmented reality app that comes with the Ugears STEM model.
The Ugears STEM lab collection mechanical puzzle VARIATOR is a fully functional wooden replica of the rubber Continuously Variable Transmission. The continuously variable bevel gear changes the drive ratio by moving a gear up and down the bevel roller shaft. In the Ugears Variator model, the belt is manually driven through the reducer and transfers the motion to the pulleys. Use the transmission fork to change gears and watch the pulley drop and rise while the pulley speed remains constant. Due to the open design of the model, you can see the whole process.
