Description The Belt Drive block represents a pair of pulleys connected with a flexible ideal flat or V shaped belt When you set Belt type to IdealNo slip the belt does not slip relative to the pulley surfaces The block accounts for friction between the flexible belt and the pulley periphery If the friction force is not sufficient to drive the load the block allows slip

History The mechanical belt drive using a pulley machine was first mentioned in the text the Dictionary of Local Expressions by the Han Dynasty philosopher poet and politician Yang Xiong 53–18 BC in 15 BC used for a quilling machine that wound silk fibers on to bobbins for weavers shuttles The belt drive is an essential component of the invention of the spinning wheel
