Abstract

DC60 (21/07/58) Outboard engines with engines provided with a power transmission mechanism. The power transmission mechanism consists of a drive shaft driven by the engine and a propeller shaft driven by the drive shaft through a bevel gear mechanism. The bevel gear mechanism consists of a driven bevel gear attached to the drive shaft and a driven bevel gear and a reverse bevel gear arranged around the propeller shaft so that they face each other and are engaged with the driven bevel gear, and the driven bevel gear and the reverse bevel gear are always engaged with the driven bevel gear and are selectively disconnected from the propeller shaft through a clutch mechanism. The driven bevel gear, the driven bevel gear and the reverse bevel gear are made of a spur gear type, and only the driven bevel gear is provided with a crest that extends the side surface of each tooth outward in the direction of the tooth thickness at the center position in the direction of the tooth width. Edited Summary of Invention 21/07/2015 An outboard engine having an engine provided with a power transmission mechanism, the power transmission mechanism comprising a drive shaft driven by the engine and a propeller shaft driven by the drive shaft by a bevel gear mechanism, the bevel gear mechanism comprising a driven bevel gear fitted to the drive shaft and a driven bevel gear and a reverse driven bevel gear arranged around the propeller shaft so as to face each other and engage with the driven bevel gear, and the driven bevel gear and the reverse driven bevel gear are always engaged with the driven bevel gear and are selectively disconnected from the propeller shaft by means of a clutch mechanism. The driven bevel gear, the driven bevel gear and the reverse driven bevel gear are made in the form of a spur gear, and only the driven bevel gear is provided with a cusp section extending the lateral surface of each tooth outward in the direction along the tooth's center in the direction along the tooth width. ------------------------------------------------------------------- The power transmission device consists of a drive shaft driven by the engine, and a propeller shaft driven by the drive shaft through a bevel gear mechanism. The bevel gear mechanism consists of a driven bevel gear attached to the drive shaft and a driven bevel gear and a counter-driven bevel gear arranged around the propeller shaft so that they face each other and are engaged with the driven bevel gear, and the driven bevel gear and counter-driven bevel gear are always engaged with the driven bevel gear and are selectively disconnected from the propeller shaft through a clutch mechanism. The driven bevel gear, the driven bevel gear and the counter-driven bevel gear are made of a spur gear type, and only the driven bevel gear is provided with a cusp section that extends the side surface of each tooth outward in the tooth thickness direction at the center position in the tooth width direction.
