Calculations can be made for any combination of external loads, namely axial and radial forces and bending moments, as well as axial and radial preloads allowed for the type of screw drive under consideration. When determining the durability, not only constant, but also time-variable external force factors can be taken into account.
To carry out calculations, it is necessary to know only the tolerance values, which allows using the APM Screw at the design stage of new equipment. By performing a series of calculations, it is possible to choose the rational dimensions of the transmission and the value of the optimal preload.
The results of the calculation are presented in various ways, namely in the form:
Appropriate forms of presentation make it possible to obtain a comprehensive description of the movement of the helical gear.
