<p>The reduction gear box comprises a housing (2), an input shaft (3) having its longitudinal axis (A) horizontal and coupled to a drive shaft, an output shaft (4) having its longitudinal axis (B) horizontal and coupled to a utiliser shaft, and several drive reduction stages within the housing between the input shaft and the output shaft. One stage (21) after the first stage includes a gear pair constituted by a hypoid bevel pinion and a bevel crown gear (26) with mutually perpendicular axes, the axis (C) of the pinion being offset from the axis (B) of the crown gear by a distance (X) such that the axes (A and B) of the input shaft and of the output shaft intersect at right angles and lie in the same horizontal plane. <IMAGE></p> |
