Learn how the Tachometer works 

A tachometer is a device designed to measure the rotational speed of different parts in engines and other systems. It calculates revolutions per minute (RPM). The tachometer also measures and keeps track of load limits, in order to reduce or increase RPM so that the engine or system runs within its ideal parameters.

Who developed the Tachometer, and when?

The tachometer was developed by the German engineer Dietrich Uhlhorn in 1817. His development was a special gadget that determined centrifugal force. From 1840 on, this gadget has actually been utilized in railway locomotives, and later in automobiles and all manner of car transport.

Use

The tachometer is utilized in systems where it is essential to properly track RPM to prevent the negative effects of overloads. Smart motorists utilize tachometers to know when to move equipments (in automobiles with manual transmissions) and to control the load on the engine, therefore increasing the running life of their vehicles.

What the Tachometer consists of and how it works

The 3D Tachometer model set from UGEARS' STEM Laboratory collection is a fully functional do it yourself wood model of a tachometer, ready for you to assemble. When the manage is turned, motion is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal system. The higher the RPM, the more centrifugal force separates the weights, moving a movable axle with a flywheel. A pointer system (dial) is fixed to the axle; the more the axle shifts (higher RPM), the more the dial arrow deflects, showing higher speed rotation.

The system of the Tachometer model set consists of:

Manage

Reducer

Weights

Axle

Flywheel

Dial

Connect the Tachometer to the Variator, producing a new system

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

When the manage of the Variator is turned, the motion is transmitted through the reducer to the cone-shaped driving wheel. The rotation of the very first cone is then transmitted through the belt to the other cone, which is the driven wheel. When the pedal attached to the housing is pushed, it moves the fork holding the belt, therefore changing the rotational speed of the driven wheel. When the Tachometer is attached to the Variator, the changing rotational speed of the driven wheel of the Variator is transmitted to the Tachometer's reducer. This in turn will increase or reduce the centrifugal force on the weights, moving the axle with flywheel. Moving the axle deflects the indicator on the dial towards a greater or lower value. In this way, modifications to the transmission ratio in the Variator will be seen to increase or reduce the RPM of the attached Tachometer.
