Description
This unit is designed to determine the co-efficient of friction of different types of belts. The belts are one of the means of transferring energy from one object to other. There performance and life is greatly affected by the friction. If the friction is too large, a big part of energy will be wasted to overcome that friction and the belt will undergo a lot of wear as well. On the other hand, friction is important for performance of belt as well because if there is low friction between belt and pulley, the slippage will occur.
The unit consists of a pulley fitted on a frame. The pulley has grooves for different types of belts. The belt is passed over the pulley at desired angle and load is applied on it via hanger. The pulley is then made to rotate against that load by the help of a cord which has a hanger and weights on its one end.
