MECA3 Expériences Transmissions
Most recent machines require the transmission of motion between elements to obtain the desired mechanical result.
Most recent machines require the transmission of motion between elements to obtain the desired mechanical result. The mechanisms studied in this module are those that transmit motion between two axles.

Verification of the speed of rotation of the two pulleys is inversely proportional to their diameters. To measure the difference in tension between the two sides of a belt drive and to determine the efficiency of drive transmission.
- Chain drive. Verification of the speed ratio of a chain drive. Measurement of the efficiency of drive transmission.
- The Geared winch (two parallel axles). Comparison of the velocity ratios of a system of single-stage and double stage geared winch. Specification of their corresponding mechanical advantages and efficiencies under varying loads.
- Bevel gears (two intersecting axles). Verification of the efficiency velocity-ratio and mechanical advantages of the Bevel gear unit under different loads.
- Worm gear (two crossed axles). Verification of the speed ratio of a worm and specification of the transmission efficiency under different loads.
- Universal coupling. To investigate the effect of introducing universal coupling to a simple drive shaft.
