Gala sound preventing device of the reduction gear with a wet clutch

摘要

(57) [summary] [purpose] disposed sub-relief valve to the wet clutch control system of marine Maringiya with a main relief valve, reduction gear rattle of which was equipped with a wet clutch that can reduce the rattle in very low-speed rotation to provide a prevention device. [Configuration] and hydraulic oil system 31 to send the actuating oil in wet clutch 2 and 3 is attached to the reduction gear via a switching valve 38 from the pump 33, to bypass than said system 31, the clutch through the main relief valve 40 The Sub in the control system of the wet clutch and a lubricating oil system 41 for sending lubricating oil in the lubrication points, which is opened in parallel with the main relief valve 40 to the hydraulic fluid system 31, when pressure from the main relief valve 40, including By connecting the relief valve 45, the switching valve 38 When and engine at the neutral position becomes extremely low speed rotation, Open only the sub-relief valve, and allowed to drop even more wet clutches in the hydraulic, because the are drastically the amount of oil traces can reduce the glass sound.
