Failure mechanism was high cycle

Failure mechanism was high cycle fatigue. This is largely due to the increased level of work and tension required of the drive pulley as well as the potential for additional loads produced from the setup of the drive device. endobj 1 0 obj 0000075808 00000 n lMs ~[ob a'>Pn%~dzzpK5.

In addition to providing some degree of belt tension to the conveyor system, the load of the conveyed product can also contribute to the load being directly applied to the conveyor pulley. The following application variables need to be considered in the selection of both the pulley outer diameter and the shaft diameter: Most conveyor belt manufacturers recommended the minimum pulley diameter specification for conveyor belting based on the individual belt characteristics such as the belt material, constructionand profiles. Mumbai, Maharashtra, No. The greater the amount of load applied to the pulley, the greater the shaft diameter required to properly support the load.
