Using special mounts this position can be adapted to different positions and ways of mounting (Fig. , but these sol utions are somewhat expensive than usual foot - mounted or flange -mounted solutions.

Gear reducer with horizontal shaft arrangement, with the housings with feet on all four sidewise sur faces and with connected flanges (Fig. 1 and presents the most universal gear reducer. This type of reducer is adapted for all positions and ways of mounting, but at the same time , it is the most expensive due to extensive machine processing and the argest consumption of materials. Therefore, their intensive development could not be expected further, but they will be produced by an only small
