UGears Tachometer Stem Lab UGR70153
FEATURES
- The Tachometer 3D puzzle from UGears STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit.
- A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms. It calculates revolutions per minute (RPM). 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.
- Connect the Tachometer to the Variator, creating a new mechanism The Variator-Tachometer system demonstrates the direct relationship between the transmission ratio of a gearbox, and rotational speed.
- Assemble the Tachometer and discover how it works. The model kit comes with a QR-code to the study guide about the mechanism, the principal of its working, the main characteristics, formulas. It also includes interesting assignments.
- Dive into augmented reality and look at how the Tachometer works. Interact with the model via a special AR application from UGears. Point your tablet or mobile phone at a fully assembled STEM-lab model and the app will show you various applications of the mechanism you've just built.
- Kit contains all required components and no glue is required
- Precision laser cut plywood. Only requires assembly.
- UGears Mechanical Models are self-propelled, mechanical wooden model assembly kits.
- Perfect for family projects, puzzle enthusiasts, and hands-on STEM learning
- 133 parts
- Assembly time: 1.5 hours
- Model size 240x103x123mm

Learn how the Tachometer works
A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms. It calculates revolutions per minute (RPM). 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.
Who invented the Tachometer, and when?
The tachometer was invented by the German engineer Dietrich Uhlhorn in 1817. His invention was a special device that measured centrifugal force. From 1840 on, this device has been used in railway locomotives, and later in cars and all manner of vehicular transport.
Use
The tachometer is used in mechanisms where it is necessary to accurately track RPM to avoid the negative consequences of overloads. 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.
What the Tachometer consists of and how it works
The Tachometer 3D puzzle from UGEARS' STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. 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.
The Tachometer mechanism consists of:

Connect the Tachometer to the Variator, creating a 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 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.
