MARINE REDUCTION AND REVERSE GEAR AND HYDRAULIC DEVICE OF MARINE REDUCTION AND REVERSE GEAR

摘要

ABSTRACTMARINE REDUCTION AND REVERSE GEAR AND HYDRAULIC DEVICE OF MARINE REDUCTION AND REVERSE GEARA marine reduction and reverse gear comprises a communication passage (309) extending from a hydraulic oil passage (210a), which is between a forward-reverse selector valve (206) and a hydraulic pump (202), to a lubricating oil passage (303a). A piping passage (307e) for detecting the hydraulic pressure in the hydraulic oil passage (210a) and a piping passage (307f) for detecting the hydraulic pressure in the lubricating oil passage are connected to a source pressure distribution plate (51). The source pressure distribution plate (51) is disposed at substantially the center on a hydraulic device mounting surface (10) provided to the marine reduction and reverse gear (1). The forward-reverse selector valve (206) and a hydraulic pressure detection means comprising pressure sensors (52a, 52b...) are disposed around the source pressure distribution plate (51). Also, an input shaft (2) is parglelly disposed between a first PTO output shaft (40) and a countershaft (6). A second PTO output shaft (5) is parallelly provided to an outer side-section of a countershaft (6) of a housing case (7). An auxiliary electricity generator (504) for small electric power is connected to the second PTO output shaft (5).Fig. 3 ABSTRACTMARINE REDUCTION AND REVERSE GEAR AND HYDRAULIC DEVICE OF MARINE REDUCTION AND REVERSE GEARA marine reduction and reverse gear comprises a communication passage (309) extending from a hydraulic oil passage (210a), which is between a forward-reverse selector valve (206) and a hydraulic pump (202), to a lubricating oil passage (303a).
