Description Générale

The Gearbox unit "MCC" has been designed to represent the typical position of a simple gearbox with three gears ratio and reverse.

Basically, the gearbox consists of several gears of different size that can be meshed as required. Those gears are visible in order to help the students to understand the different principles involved, as well as the operation of a gearbox.

Gears are arranged and fixed on different shafts (input shaft, output shaft, fixed shaft and reverse) that are mounted on ball bearings which, together with the displacement mechanisms, guarantee a smooth shifting and reduce losses due to friction.

Pulleys with protractors are coupled to the input and output shafts so the student can determine and verify torque and speed ratio.

  • Primary shaft (or input shaft).
  • Secondary shaft (or output shaft).
  • Intermediate shaft (or fixed shaft).
  • Gears.
  • Gearshift lever.
  • Pulleys.
