· Example: To upgrade the service factor from 1.25 to 1.50 means the mechanical components of bearings gears, etc. must be built for a 1.8 times equivalent life expectancy of the 1.25 service factor unit. Belt overstressing : The belt manufacturers limit the amount of momentary overstressing to approximately 140 percent.
the length correction factor. This factor is a number smaller than 1 for shorter length and higher for longer belts. This reflects the fact that a longer belt will be less prone to wear and tear as opposed to a shorter belt. When the given torque from the table is
The load support of a belt is a factor of the belt width, belt strength and bulk material density. The table indicates the minimum belt width required for good troughability based on three idlers of the same length set at 30 . Other carcass constructions and belt *
Determine the load factor by observing the load factor chart below. Ex. Assume that the leg angle will be 60°. The load factor for 60° from the load factor chart is 1.154. Multiply the load factor times the minimum weight to be supported by the leg, i.e. 1,000 pounds times 1.154=1154 pounds. The rated sling capacity needed is then 2,308 (1 ...
How many items per second that are moved from one tile to the next. That is density (items per tile) multiplied by speed (tiles per second), e.g. for a basic belt it is 4 * 1.875 = 7.5 items per second, for one belt lane. For both lanes it is doubled, i.e. 15 items per second. Compression.
