Fig. 1 . The characteristic solutions of position and way of mounting of single -stage gear reducer ( Rossi solution) [1]. Modern single -stage universal gear reducers with horizontal and vertical shaft arrangement are highly universal gear units, adapted for different shapes and mounting positions (Fig. . Company NRW is one of the less known gearbox manufacturers and, beside other gear reducers, NRW produce single -stage gear units with vertical shaft arrangement. It produce the most complete gear reducer program (Fig. 1, 1 , . NRW is one of th few manufacturers who produce oot-mounted single -stage gearboxes with an output shaft positioned both up and down (Fig. . The utput shaft is very rarely positioned above the pinion since it often prevents installation of motor gear reduce on flat surface. This manufacturer also produce foot and flange -mounted single -stage gear units for three different flange diameters, which is rarely required. It also produce flange -mounted gear reducers with different flange diameters that are connected with housing by screws (Fig. . NRW produces gear units with the classic input shaft and with the adapter for IEC motors with flanges B5 and B1. The design of the housing is quite complex , taking into account the cost savings of the material as well as the reinforcement of the housing. The form is simple and attractive (Fig. . [5] Fig. 1 .
