Gear Efficiency Apparatus .

Description of Gear Efficiency Apparatus

The input and output power of the Gear Efficiency Apparatus is calculated for determining the Gear Efficiency of two different gear configurations. The Gear Efficiency Apparatus has a gearbox which incorporates both spur and worm gears for which the setups can be easily switched between. The motor speed input can be controlled as well as a breaking force or load applied to the output shaft via a braking module. Sensors for speed and force are located on the motor module (input) and the brake module (output).

By taking the input and output force (N) readings we can then calculate the torque (Nm) in the shafts as well as go on to calculate the power (Nm/s). By comparing the actual input and output readings to that of the calculated output values we can affectively work out the losses in the system and the efficiency of the respective gear configurations.
