Plate Clutch Friction Apparatus- Engineering Lab Training Systems

Features Low cost, effective teaching. Self-contained. Wall mounted. Brake lining friction material. Variable plate pressure. 3 diameters of friction plate. Determination of coefficient of friction. Three year warranty.   Range of Experiments To determine the coefficient of friction of the plate material. To show that the minimum torque to maintain rotation is proportional to the axial load and diameter of the friction disc.   Description The wall mounted apparatus comprises a lower stationary plate with friction discs and an aluminum alloy plate whose shaft rotates in ball bearings but which is in direct contact with the stationary plate. The minimum force on the friction disc is the self weight of the upper plate, but the contact pressure can be increased by adding weights to the upper plate. Pure torque is applied to the upper plate through two loaded cords and pulleys. Three interchangeable friction discs are supplied of different diameters. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results.
