Abstract

Belt stretch introduces an extra dimension to the load-sharing problem. In order for a drive drum to transfer power to a belt, it experiences tension in the belt by stretching such that a section of belt entering the drum is longer than the same section of belt as it leaves the drum. In order to stretch a belt, speed of the drum must be equal to or greater than belt speed at all points of contact. Ideally, the speed of a belt entering a drum is equal to the speed of the contact surface of the drum. The speed of the belt leaving the drum is lower by the amount of belt stretch. Besides, the project will study the effect of belt stretch in relation to various rotational speeds. Universal Testing Machine was used to study the belt stretch. All the data were taken by the experiment conducted and calculation. From the experiment, data shows that the belts stretch increase with increasing belt velocity.
