Document Type and Number:
Japanese Patent JP2015199373
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 comprises one hydraulic pump 41 and two hydraulic motors 42 and 43. The hydraulic pump 41 is driven by the main engine 7, a screw 5 that makes a hull to generate thrust in a longitudinal direction is driven by a first hydraulic motor 42, and a side thruster that makes the hull to generate thrust in a left-and-right steering direction is driven by a second hydraulic motor 43.
