nit to increase their rigidity. Fig. 7. The characteristic solution of foot -mounted single -stage gear reducer with the horizontal arrangement of the shafts and ribs at the housing (Flender solution) [1]. To simplify the gearbox production as much as possible , many manufacturers produce one -piece housings to avoid machining of large contact areas between two parts of the housing . They have to provide an opening for large gears, usually at the top of housing (Fig. or on one of the front side (Fig. 9 and which afterward should be closed with cover. With this approach, they significantly simplify the machining of the housings, although the assembling of such gear units is somewhat more complex. Fig. 8. The characteristic solution of foot -mounted single -stage gear reducer with the horizontal arrangement of the shafts (Hansen solution) [1]. Today, as stated above, basic attention is paid to aesthetic, .. product design. Modern solutions of single -stage universal gear reducer are recognized by simple and attractive form, slight shape transitions and somewhat higher material consumption. It is interesting to note that some manufacturers assemb le single -stage gear reducers in the housings for two -stage gear units (cylindrical -bevel gear reducers) to increase the series of housing and thereby reduce production costs (Fig. 9 and .

The characteristic solution of foot -mounted single -stage gear reducer with the horizontal arrangement of the shafts (Hansen solution) [1]. In order to increase the versatility of their gear reducers, some manufacturers produce the housings with feet on all four sidewise surfaces. In this way , the gearbox ca be mounted with horizontal shaft arrangement, but also in vertical shaft arrangement . The additional opening is added throu
