Document Type and Number:
Japanese Patent JP2015199372
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a marine gear device whose power transmission system is made simple and compact so that a side thruster can be used even for a comparatively small vessel.SOLUTION: The marine gear device has a hydraulic variable transmission 30 that changes speed of power of a main engine 7 mounted on a hull. The hydraulic variable transmission 30 has a structure in which a hydraulic pump 41 to be driven by the main engine 7, a first hydraulic motor 42 that drives a screw 5 that makes the hull to generate thrust in a longitudinal direction and a second hydraulic motor 43 that drives a side thruster that makes the hull to generate thrust in a left-and-right steering direction are connected in series by hydraulic closed circuits 44 and 74.
