Abstract
The utility model relates to a steering system for an outboard engine which comprises a power mechanism, an operating rod, an upper cylinder body, a lower cylinder body, a transmission shaft and a propellor. The steering system is improved in that a steering shaft is arranged in the upper cylinder body and the lower cylinder body; the upper cylinder body and the lower cylinder body are connected with each other through the steering shaft; the steering shaft vertically passes through a second bearing, a first oil seal and a second oil seal and can be rotationally assembled in the upper cylinder body through two lock nuts; the lower end of the steering shaft is fastened and connected with the lower cylinder body; the transmission shaft passes through the inner hole of the steering shaft; the operating rod is connected and fixed with the lower cylinder body. When the steering system provided by the utility model works, the engine is fixed, the steering is realized through the propellor by operating the lower cylinder body, and the steering system is light, and flexible, and has good stability under transport condition.
Description
Technical field
The utility model belongs to marine engine technical field.
Background technology
Traditional outboard engine is to turn to by joystick control engine, driving system, screw propeller entirety.This is for high-performance outboard engine, and because driving engine is heavier, manipulation labour intensity is large, when especially ship travels in billow, implements to turn to by changing the center of gravity of driving engine, and poor stability, easily shines into safety misadventure.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, proposes a kind of steering swivel system of outboard engine, and driving engine is maintained static, and by manipulation lower shell, screw propeller is implemented to turn to, and has the features such as light, flexible, riding stability is good of handling.
The technical solution of the utility model is as follows:
A steering swivel system for outboard engine, comprises actuating unit, joystick, upper shell, lower shell, transmission shaft and screw propeller; Described drive shaft cartridge is in upper shell and lower shell, and the mouth of transmission shaft upper end and actuating unit is in transmission connection, and lower end and screw propeller are in transmission connection, and described upper shell upper end and motivation mechanism are fastenedly connected, and screw propeller is installed in the lower end of described lower shell.
Its improvement is, is also provided with steering shaft in described upper shell and lower shell, realizes connection by steering shaft; Steering shaft is assemblied in upper shell with two jam nuts rotationally by the second bearing, the first and second oil sealings up and down; Lower end and the lower shell of steering shaft are fastenedly connected; Described transmission shaft passes from the endoporus of steering shaft; Described joystick and lower shell are connected and fixed.
The principle of work of above steering swivel system is as follows: in the time that ship need to turn to, joystick rocks from side to side, drive lower shell by joystick, lower shell drives steering shaft, steering shaft freely rotates under upper shell fixation by the second bearing, steering shaft positioning action, lower shell drives propeller turning direction, thereby reaches the object turning to.
Visible, this steering swivel system has the following advantages:
1,, for high-performance outboard engine, do not need the gravity that overcomes driving engine to implement to turn to, light, flexible, raising manipulation traveling comfort.
2, while turning to, do not change driving engine center of gravity direction, improve riding stability.
3, driving engine has reduced engine vibration aboard ship by connecting panel is directly fixing, raising workpiece service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of this steering swivel system
Fig. 2 is the partial enlarged drawing of Fig. 1.
In figure: 1 driving engine, 2 change speed gear boxs, 3 control lever, 4 support upper plates, 5 connecting pins, 6 support lower plates, 7 hulls, 8 driven wheel of differentials, 9 clutch shaft bearings, 10 first oil sealings, 11 jam nuts, 12 steering shafts, 13 transmission shafts, 14 upper shells, 15 second oil sealings, 16 second bearings, 17 lower shells, 18 screw propellers.
The specific embodiment
Describe structure of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, the assembling mode of the drive machine of outboard engine like the prior art, support upper plate 4 is connected with driving engine 1 screw, support upper plate 4 is connected by connecting pin 5 with support lower plate 6 and can mutually rotates, and support lower plate 6 is fastenedly connected with hull 7, and driving engine 1 is assembled into one with change speed gear box 2, power is provided, upper shell 14 upper ends and gearbox body are fastenedly connected, and by body Action of Gravity Field, the cylindrical of upper shell 14 contacts with support lower plate 4.
Difference is that native system is fastened on joystick 2 on lower shell 17, has increased steering shaft 12 simultaneously, is arranged in upper shell 14 and lower shell 17, connects lower shell by steering shaft.Specifically, steering shaft 12 is fixed in upper shell 14 by the second bearing 16, the second oil sealing 15 and two jam nuts 11 of the first oil sealing 10 use, forms with upper shell the relation that is rotatably connected.The lower end of steering shaft 12 is fastenedly connected lower shell 17.Transmission shaft 13 passes from the endoporus of steering shaft 12, and the driven wheel of differential 8 of transmission shaft 13 upper ends and gear box output end is in transmission connection, and lower end is in transmission connection by gear and screw propeller 18, and screw propeller 18 is arranged on lower shell 17 lower ends, and axially vertical with lower shell.
Driven wheel of differential 8 is arranged on the upper port of upper shell 14 by clutch shaft bearing 9, driven wheel of differential 8 is connected with the gear of change speed gear box 2.
In the time that ship need to turn to, the joystick 3 that rocks from side to side, drives lower shell 17 by joystick 3, lower shell drives steering shaft 12, under steering shaft 12 upper shell 14 fixations, freely rotates, and plays the role of positioning, lower shell 17 drives screw propeller 18 to turn to, thereby reaches the object turning to.
In the time that screw propeller need to depart from the water surface, to pressing down joystick, driving engine 1, change-speed box 2, support upper plate 4 rotate around support lower plate 6 by connecting pin 5, upper shell 14 and support lower plate 6 with separate.
