The preload of a bolted joint design is generally based on the tensile yield strength of the bolt or fastener used. For the calculations in this post, it will be assumed that the yield strength of the internal threads is larger than the proof strength of the fastener threads, causing the limiting factor to be the fastener used.
Therefore: SC = 1.50 X 3.75 X 333 ft 3 /hr SC = 1,873 ft 3 /hr. The Selection Capacity will be used to select the proper screw conveyor diameter and speed from the Capacity Table. With a recommended trough loading of 30A, the Selection Capacity must be less than the maximum capacity given in the Capacity Table.
HORSEPOWER REQUIREMENT (INCLINED SCREW CONV.) ADVANTAGES: Inclined screw conveyor is often very desirable as it may solve a conveying problem with a minimum of equipment and occupy a minimum space DISADVANTAGES: The capacity, or the maximum available capacity of a given screw conveyor decreases with increase of incline The horse …

Note that the preload torque fluctuates due to manufacturing tolerances and lead variation, so manufacturers will either provide a range of allowable values (for example, 0.04 to 0.17 Nm), or they will indicate an allowable percentage variation from a nominal preload torque value (for example, 0.10 Nm, ±40 %).
Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may …
