Lead screw sizing in 4 steps

Lead screw sizing is a bit of a hybrid exercise, with similarities to the process of ball screw sizing, but incorporating some of the considerations that come with sizing a plain bearing. Although back driving is only applicable in vertical applications, it is sometimes a key factor in the decision of whether to use a lead screw or a ball screw. Get price

Shear Pin/Screw Calculations

Using online screw tables to find the pitch diameter and minor diameter for these screws, we calculate the pitch and minor areas. Finally, we compute the minimum shear strength of the screw by multiplying the minor area by the smaller material shear strength value; and compute the maximum shear strength of the screw by multiplying the pitch area by the larger material shear strength value.

Flexible Screw Conveyor Design Maximizes Productivity

Screw conveyors typically range in diameter from 2 to 8 in., and can be used for horizontal transports of up to 80 ft, and inclines of up to 60 degrees. An 8-in.-diam screw conveyor can transport 1800 cu ft/hr at 360 RPM at a 45-degree angle. Get price

Worm Gearing

Worm diameter d1 is virtually arbitrary with the chosen number of worm teeth z1 and the known module value (mx or mn), unless a certain value of pitch angle gis required. In the effort towards the least possible number of screw cutters for manufacturing work gears, the manufacturers recommend choosing d1=q•m, where q is the coefficient depending on the size of standardized module m.

Screw Feeder

A simple type of screw feeder is shown in Fig. 5.15.Rotation of the screw moves a continuous plug of material into the pipeline, where it is dispersed and entrained with the conveying air. A particular advantage of screw type feeders is that there is an approximate linear relationship between screw speed and material feed rate, and so the discharge rate can be controlled to within fairly close Get price
