Screw thread Calculations

The length of the screw engagement should therefore be sufficient to carry the full load necessary to break the screw without the threads stripping. The size of a screwed fastener is first established by calculating the tensile load to be withstood by the screw and selecting a suitable screw to withstand the tensile load with the appropriate Get price

Screw Conveyor Horsepower

The Corrected Material Horsepower Factor, sometimes called the Overload Factor, is used to increase the Total Shaft Horsepower (TSHP) of a screw conveyor when the calculated Material Horsepower (MHP) is less than 5-HP. Increasing the TSHP allows the screw conveyor to overcome most upset conditions, reducing downtime and loss of production. Get price

How to avoid ball screw buckling

May 21, 2015Determining the buckling load is an important step in ball screw sizing. The buckling (compressive) load can easily be calculated based on the screw's root diameter, unsupported length, and end bearing configuration. where: F c = maximum compressive load (N) f b = end bearing factor. d 1 = root diameter of screw (mm) L = unsupported length (mm) Get price

Blocking Fault Analysis of Screw Conveyor

Since screw conveyor conveying space is small and it is sensitive to material, intertwining phenomenon is easy to occur when screw shaft rotates, blockage occurs in the place of hanging bearing. So blocking problem is the most common fault of screw conveyor which will affect production and increase power consumption, even the motor will burn out and screw shaft twist off which will affect the Get price

Bolted Joint Analysis

Per Shigley, the proof strength is approximately equal to 85% of the tensile yield strength, S ty.Based on S proof = 0.85S ty, the recommended preload force as a function of yield strength is: . Considering that the above values are conservative, a general rule of thumb is to preload the fastener to 2/3 of the yield strength (i.e. % yld = 66.7%). Get price
