Belt pulley systems transfer power and motion from shaft to shaft via a flexible, bendable belt wrapped
around pulleys. The flexibility and bendability of the belt prevent the negative effects, such as vibration
and impact, that may occur on one shaft from being transferred to the other shaft. Power transmission
occurs through the friction (force) bond between the belt and the pulley. There may be slippage between
the belt and the pulley during moment increases. While this provides an advantage in that sudden load
increases are not transmitted to the motor shaft, it provides a disadvantage in that it does not provide a
constant rotation ratio. Other disadvantages of these mechanisms are that permanent elongation occurs
in the belt over time, and tensioning systems are needed to eliminate the looseness. In addition to these
disadvantages, the shaft bearings are strained due to the forces exerted by the arms pressing the belt
against the pulley, and the power transmission is limited by the belt's strength. In this study, a group of
pulleys consisting of different diameters was used as a tension pulley as an alternative to weighted or
spring tension pulleys. Different amount of weights that have different distances from the main pulley
(Driven pulley) hub were tested with different rotation speeds and tension pulleys with different
diameters in the experimental set. In addition, the resulting main pulley rotation numbers were tried to
be estimated by artificial intelligence methods too. Thus, by ensuring minimum slippage with the most
suitable tension pulley diameter, an attempt was made to prevent possible strain on the shaft bearing
and belt.
