Bearing Friction Apparatus [Code: FT005]

Bearing Friction Apparatus
Description & Specification:

Bearing Friction Apparatus.
Bearing Friction Apparatus Features Low-cost effective teaching Self-contained Wall mounted Comparative friction of 4 bearing materials Can double as flywheel apparatus Three year warranty   Range of Experiments To compare the frictional losses of bearings by measuring the coefficient of sliding friction between pairs of materials To measure the reduced losses when a ball or roller bearing is used   Description The apparatus consists of a flywheel on a horizontal shaft carried in a pair of similar bearings, the flywheel being used to even out small variations in friction. The shaft is of mild steel, and interchangeable bearings in a range of materials are provided. This experiment provides an opportunity to study journal bearing friction over a range of commonly used materials including a self lubricating sintered bronze. For comparison a ball or roller bearing is available to demonstrate the advantages of rolling rather than sliding contact. Torque is applied by a loaded cord wrapped round the flywheel shaft. 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.
