Description:

Features:

• Recommended for ages 8+ years
• This device has been used in railway locomotives, and later in cars and all manner of vehicular transport
• A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms
• The tachometer is used in mechanisms where it is necessary to accurately track RPM to avoid the negative consequences of overloads
• The model kit comes with a QR-code to the study guide about the mechanism, the principal of its working, the main characteristics, formulas and it includes interesting assignments
• The Tachometer 3D puzzle from UGEARS’ STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble
• Savvy motorists use tachometers to know when to shift gears (in cars with manual transmissions) and to control the load on the engine, thereby increasing the operating life of their vehicles
• Dive into augmented reality and look at how the Tachometer works and interact with the model via a special AR application from Ugears
• The tachometer also measures and monitors load limits, in order to decrease or increase RPM so that the engine or mechanism runs within its optimal parameters
• When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit
• The higher the RPM, the more centrifugal force separates the weights, shifting a movable axle with flywheel
• A pointer mechanism (dial) is fixed to the axle; the more the axle shifts (higher RPM), the more the dial arrow deflects, indicating higher speed rotation
• When the handle of the Variator is rotated, the movement is transmitted through the reducer to the cone-shaped driving pulley
• The rotation of the first cone is then transmitted through the belt to the other cone, which is the driven pulley
• When the pedal attached to the housing is pressed, it shifts the fork holding the belt, thereby changing the rotational speed of the driven pulley
• When the Tachometer is attached to the Variator, the changing rotational speed of the driven pulley of the Variator is transmitted to the Tachometer’s reducer
• This in turn will increase or decrease the centrifugal force on the weights, shifting the axle with flywheel
• Shifting the axle deflects the indicator on the dial toward a higher or lower value
• In this way, changes to the transmission ratio in the Variator will be seen to increase or decrease the RPM of the attached Tachometer
