The Epicyclic Gear Unit (3 elements), "MTE3", consists of three coupled epicyclic gears sets. It will allow the students to carry out experiments of different gear ratios, as well as the torque conversions.
The epicyclic gears installed in the "MTE3", unit are the same and they consist of the following elements:
- Sun gears (Z=21).
- Satellite gears set (Z=21).
- Ring (Z=63).
The unit has two graduated discs located at the input and output shafts, which will allow to check the velocity and torque ratios according to the application of the different brakes.
The power arrives to the epicyclic gears through the sun gears.
- Demonstration of the function of an epicyclic gear system.
- To determine and verify the velocity and torque ratios between the input and output shafts.
- Study of the mechanical advantage and efficiency of a planetary system.
- Determination of the angular displacement at the input and output and comparison with calculated ratios.
- Determination of the minimum force at the input to move a weight at the output.
- First gear.
- Second gear.
- Third gear.
- Reverse gear.
- Checking the relation between the input motor torque and the output motor torque.
