Abstract:
A marine reduction gear makes it possible to reduce the installation space of an electrical rotating machine. A marine reduction gear includes: an input shaft coupled to an output shaft of an engine; an output shaft coupled to a propeller shaft that rotates a screw propeller; a gearbox accommodating an input gear provided on the input shaft and an output gear provided on the output shaft, the gearbox supporting a first bearing that supports the output shaft in a rotatable manner; and an electrical rotating machine including: a central shaft that rotates together with the output shaft; a rotor fixed to the central shaft; and a stator surrounding the rotor. The gearbox supports the stator and a second bearing that supports the central shaft of the electrical rotating machine in a rotatable manner.

Claim (Index 2):
The marine reduction gear according to  claim 1 , further comprising a lubricating oil pump mounted to the gearbox and driven by the input shaft, wherein\n the lubricating oil pump circulates lubricating oil such that the lubricating oil flows downward in the gearbox, and supplies the lubricating oil to the second bearing, and the lubricating oil supplied to the second bearing is ejected from the second bearing into the gearbox.
