Learn how the Tachometer works 

A tachometer is a device created to determine the rotational speed of different parts in engines and other systems. It determines transformations per minute (RPM). The tachometer also determines and keeps track of load limitations, in order to reduce or increase RPM so that the engine or mechanism runs within its optimum parameters.

Who developed the Tachometer, and when?

The tachometer was developed by the German engineer Dietrich Uhlhorn in 1817. His creation was an unique gadget that measured centrifugal force. From 1840 on, this gadget has actually been used in railway locomotives, and later in cars and all manner of car transport.

Use

The tachometer is used in systems where it is necessary to properly track RPM to avoid the unfavorable effects of overloads. Savvy vehicle drivers utilize tachometers to understand when to move equipments (in cars with manual transmissions) and to control the load on the engine, thereby increasing the operating life of their vehicles.

What the Tachometer includes and how it works

The 3D Tachometer model set from UGEARS' STEM Laboratory collection is a completely operational do it yourself wooden model of a tachometer, prepared for you to put together. When the handle is rotated, movement is transferred through a reducer, increasing the RPM and displacing twin weights in the centrifugal system. The greater the RPM, the more centrifugal force separates the weights, shifting a movable axle with a flywheel. A guideline mechanism (dial) is fixed to the axle; the more the axle shifts (greater RPM), the more the dial arrow deflects, suggesting greater speed rotation.

The mechanism of the Tachometer model set includes:

Handle

Reducer

Weights

Axle

Flywheel

Dial

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

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

When the handle of the Variator is rotated, the movement is transferred through the reducer to the cone-shaped driving pulley-block. The rotation of the first cone is then transferred through the belt to the other cone, which is the driven pulley-block. When the pedal connected to the real estate is pressed, it moves the fork holding the belt, thereby 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. Shifting the axle deflects the indication 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 reduce the RPM of the connected Tachometer.
