Abstract
The paper presents new possibilities for use in design calculations of screw devices. Proposed
settlements due to the introduction in formula the argument "performance" and apply them to
computing internal screw geometry. These formulas have the properties of "mutually inverse
correspondence" options that allow you to explore the calculations associated with the variation of
the parameter values screws. The application of these formulas ensures the objectivity of the
calculations, aimed at verification of passport characteristics of screws, the determination their
ability to various transportation cargo, the calculation of the product mass on coils of a screw
metering device, the increasing performance on surplus power auger motor current.
Keywords
