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 5):
The marine reduction gear according to  claim 2 , further comprising a coolant pump mounted to the gearbox and driven by the input shaft, wherein\n the coolant pump supplies a coolant to the electrical rotating machine, such that the coolant flows in contact with the stator of the electrical rotating machine.
