Factor of Safety in Conveyor Belts - bulk-online Forums

May 22, 2008· I would like to know the rationale behind stipulating the factor of safety in conveyor belts. Traditionally, the FoS for synthetic fabric reinforced belts is considered as 9 or 10 and for Steel cord belts as around 6.7 - 7. What is the rationale behind these numbers ? Also, by definition, is the FoS the ratio of the rated tensile strength & T1 OR is it the ratio of the rated tensile strength ...

Design Considerations for Conveyor Belt Idlers

There are three types of idlers used in the conveyor industry, out of which only the flat belt conveyor idler design calculations are discussed here theoretically. We have not used the factor of safety in the design calculations here, or in other words the factor of safety is …

V-Belt Drive Selection Handbook -

A ratio is a proportional factor between two similar objects of different sizes. In a belt drive system, a ratio is used to determine the speed relation between two v-belt pulleys. The speed ratio would be stable if slippage did not occur; however as belt slip is inevitable, the …
