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 6):
The marine reduction gear according to  claim 5 , wherein\n the coolant pump supplies the coolant to the electrical rotating machine through a first coolant supply line, and supplies the coolant to a heat exchanger through a second coolant supply line, and the heat exchanger cools the lubricating oil by exchanging heat between the lubricating oil and the coolant, the lubricating oil being the lubricating oil that is to be sucked into the lubricating oil pump or the lubricating oil that has been discharged from the lubricating oil pump.
