Outboard motor

FIELD: engines and pumps.

SUBSTANCE: invention relates to outboard motors. Proposed motor comprises housing, control shaft, propulsor, drive shaft in shaft duct and shaft duct. Drive shaft in shaft duct and shaft duct in motor housing run in radial thrust bearings. Shaft duct is provided with seal collar at lower part and is turned in motor housings by helical gear speed reducer. The latter has four conical gears locked in motor hosing by retainer. Control shaft is connected with telescopic helm or joystick by means of CVD joint or universal joint or spring-rope flexible shaft. Motor is coupled with drive shaft via automatic inertial friction or engagement clutch. Outboard motor housing is articulated with motor holder. Motor holder has hinge pivot for adjustment of motor inclination relative to board transom and clamps for reliable locking of said motor at transom.

EFFECT: ease of use.

SUBSTANCE: ship screw rudder complex incorporates a drive engine arranged above the ship water line and linked with the ship shaft running in bearing in the nacelle below the water line, the said shaft being coupled with the screw shaft accommodating the propeller screw fitted thereon. The said complex comprises also a top shaft arranged parallel to the lower shaft and coupled with the drive engine output shaft. The top and lower shafts are crankshafts coupled via a con-rod mechanical transmission arranged between them and furnished with rod bearings. Rod and main bearings of the lower crankshaft are water-lubricated plain bearings. The nacelle space can communicate with outboard.

EFFECT: higher reliability and efficiency of screw rudder columns.

FIELD: transport engineering.

SUBSTANCE: device for remote control of outboard engine includes drum with possibility of rotation by 350, with integral drive cable threads, and control handle connected via the ball pivot. Simultaneously the control handle is control rod for rotation of the engine traction vector and throttle control element. The casing with concentric slot is intended for the control handle movement during actions relating the mover rotation to different sides and for reverse. The bushing with slot simultaneously rotates with pulley for the control lever movement towards centre and back for the throttle cable movement. Controls are installed on the outboard engine and ensure proper use of the traction vector.

EFFECT: easy control of the outboard engine.
