From the developer:
cymex® lets you size and evaluate complete drive trains (application motor gearhead) incredibly easily. Its highly precise calculations are enormously simplified by predefined standard applications such as belt, tape, spindle, rotary table and rack & pinion drives. By considering all important influencing factors and customer-specific parameters, it assures a reliable and efficient design and an optimal drive system.
