Belt Friction Apparatus- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Belt Friction Apparatus- Engineering Lab Training Systems.
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.
