Belt Friction Apparatus

Model HV-EXP2575
Technical Description This benchtop unit enables experiments to be performed on belt drives and belt friction. The core of the unit is a cast iron pulley with grooves in its circumference for V-belts and flat belts. The pulley is mounted in ball bearings and is operated with a hand crank. The inertia of the pulley contributes to even rotation. The belts grip the pulley at an angle of contact from 30° to 180° in 15° steps. Two spring balances measure the tensile forces at each end of the belt. The belt tension can be precisely adjusted using a threaded spindle..
