Multi-stage angle drive reduction gear box

A multi-stage angle drive reduction gear box comprising:

• a reduction gear housing;
• an input shaft having a longitudinal axis adapted for being coupled to a drive shaft of an engine;
• an output shaft having a longitudinal axis adapted for being coupled to a utilizer shaft;
• and
• a plurality of drive reduction stages defined within the housing between the input shaft and the output shaft,
• one of said reduction stages, disposed after a first of said reduction stages, including a gear pair constituted by a hypoid bevel pinion and a bevel crown gear with mutually perpendicular axes, the axis of the pinion and the axis of the crown gear being in an arrangement in which said axes are offset by an offset distance, the other of said reduction stages having interaxial spacings whose algebraic sum in the direction of said offset distance is equalized by the arrangement of the axes of said pinion and crown gear and said offset distance therebetween, such that the axes of the input shaft and the output shaft intersect ar right angles and lie in the same horizontal plane.
