Dive into increased reality and look at how the Tachometer works. Connect with the model by means of a special AR application from Ugears.

Learn how the Tachometer works 

A tachometer is a device developed to measure the rotational speed of various parts in engines and other systems. It computes revolutions per minute (RPM). The tachometer likewise determines and keeps an eye on load limitations, in order to reduce or increase RPM so that the engine or mechanism runs within its ideal parameters.

Who invented the Tachometer, and when?

The tachometer was invented by the German engineer Dietrich Uhlhorn in 1817. His innovation was a special device that measured centrifugal force. From 1840 on, this device has actually been used in railway locomotives, and later on in vehicles and all way of automobile transport.

Use

The tachometer is used in systems where it is necessary to properly track RPM to prevent the negative repercussions of overloads. Savvy vehicle drivers utilize tachometers to understand when to shift equipments (in vehicles with manual transmissions) and to control the load on the engine, consequently increasing the running life of their vehicles.

What the Tachometer includes and how it works

The 3D Tachometer model set from UGEARS' STEM Lab collection is a fully functional DIY wooden model of a tachometer, ready for you to put together. When the handle is turned, motion is transferred through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit. The greater the RPM, the more centrifugal force separates the weights, shifting a movable axle with a flywheel. A tip mechanism (dial) is repaired to the axle; the more the axle shifts (greater RPM), the more the dial arrow deflects, indicating greater speed rotation.

The mechanism of the Tachometer model set includes:

Weights

Axle

Flywheel

Link the Tachometer to the Variator, creating a brand-new mechanism

The Variator-Tachometer system demonstrates the direct relationship between the transmission ratio of a gearbox and rotational speed.

When the handle of the Variator is turned, the motion is transferred through the reducer to the cone-shaped driving pulley-block. The rotation of the very first cone is then transferred through the belt to the other cone, which is the driven pulley-block. When the pedal connected to the housing is pushed, it moves the fork holding the belt, consequently altering the rotational speed of the driven pulley-block. When the Tachometer is connected to the Variator, the altering rotational speed of the driven pulley-block of the Variator is transferred to the Tachometer's reducer. This in turn will increase or reduce the centrifugal force on the weights, shifting the axle with flywheel. Moving the axle deflects the sign on the dial toward a higher or lower value. In this method, modifications to the transmission ratio in the Variator will be seen to increase or reduce the RPM of the connected Tachometer.
