Abstract

The utility model relates to a hanging oar and a hanging machine, an improved shifting method of which is a seft rotary method by an oar and a rudder. The utility model is provided with a self rotary body, and the shifting can be realized by motive power to directly drive the self rotary body. The utility model has the characteristics of simple structure, low cost, high reliability and convenient maintenance and operation.

Description

Outboard propulsion system with self-rotating oars and helm

The utility model belongs to a kind of hanging, on-hook that improves after the gearshift mode, and it is applicable on the carrier and uses.

As everyone knows, present hanging, on-hook have following several gearshift mode:

1. realize gearshift by the bevel gear that denture clutch engages or separation is just being reversed gear.

2. realize gearshift by the pitch that changes propeller.

3. be that engine, slurry, the whole revolution of rudder are realized gearshift by hanging peculiar to vessel, on-hook.

Above-mentioned first kind of gearshift mode exists complex structure, and between cog has impulsive force, and part is easy to wear, weak points such as cost height.

Second kind of gearshift mode exist propeller complex structure, manufacturability poor, be subject to marine corrosion and lost efficacy cost height, weak points such as maintenance difficulty.

The third gearshift mode exists engine and slurry, rudder turn round together, thereby often changes actuated position, inconvenient operation.

The purpose of this utility model just provide a kind of improvement gearshift mode by slurry, rudder is from helicoid hanging, on-hook.It is simple in structure, and cost is low, and is easy to operate.In hanging, on-hook, have one from turning, directly drive to turn certainly by power and realize gearshift.

The utility model is achieved in that has one from turning on marine propeller, hinged by bearing and pallet, makes it can do 360 degree revolutions.Its upper end is fixed with positive car bumper pin and reversing backing pin.Propeller is in from the lower end of turning.Power is passed on the propeller by a pair of master, passive bevel gear in turning certainly by transmission shaft.One selector fork is arranged on pallet.When shift fork was in neutral gear position, the revolution of turning certainly was unrestricted.When driving bevel gear is passed to power passive bevel gear propeller is rotated, also exist a kind of making from turning rotating component, this component increases and decreases with the increase and decrease of propeller rotary resistance.When the rotational resistance of turning certainly during less than the rotary resistance of propeller, turn certainly and promptly do 360 degree revolutions, this moment propeller in the body axis revolution that rotates also around the rotation of propeller axis.But,, do not advance by ship so not understanding front and back because its thrust is cancelled out each other at circumferencial direction.Just keep off or when reversing gear the position, positive car bumper pin on turning certainly or reversing backing pin and selector fork formation obstacle have stoped the rotation of turning certainly, thereby controlled the thrust direction of propeller when selector fork is in, realized advancing or falling back of ship.

The utility model has changed in the past and to impose external force by additional mechanism providing additional operation and force the method for shifting gears, and realizes gearshift by the internal force (power) of hanging, on-hook self, thereby simplifies the structure, and has improved reliability, has reduced cost, maintenance and operate all more convenient.

The utility model will be further described below with reference to accompanying drawing:

Fig. 1 is the utility model Marine outboard motor longitudinal sectional drawing.

Fig. 2 is along the cutaway view of N--N line among Fig. 1.

Fig. 3 is that A is to view.

In the drawings, 1 is gearshift controller; 2 is positive car bumper pin; 3 are the reversing backing pin; 4 is thrust ball bearing; 5 is plain bearing; 6 is pallet; 7 is nut; 8 is transmission cylinder; 9 are the hook that reverses gear; 10 is propeller; 11 is deceleration box; 12 is propshaft; 13 is passive bevel gear; 14 is driving bevel gear; 15 is transmission shaft; 16 is support; 17 is bearing; 18 is the safe transmission pin; 19 is shift handle; 20 is selector fork; 21 is key; 22 is back-up ring; 23 are the gearshift axle.

On the gearshift controller 1 of Marine outboard motor, be fixed with positive car bumper pin 2 and reversing backing pin 3, it is by thrust ball bearing 4, plain bearing 5 and pallet 6 are hinged, make it can do 360 degree revolutions, its lower end connects firmly together with nut 7 transmission cylinders 8, the other end of transmission cylinder and deceleration box 11 are in the same place by bolted, gearshift controller 1, transmission cylinder 8, deceleration box 11 threes connect firmly can be rotating from turning around axis 360 degree, transmission shaft 15 links by spline and driving bevel gear 14, also is to connect with propshaft 12 with spline with the passive bevel gear 13 of driving bevel gear 14 ingears.Propeller 10 is fixed on the propshaft 12 by safe transmission pin 18.One selector fork 20 that controlled by shift handle 19 is arranged on pallet 6, and it is positioned on the gearshift axle 23 by key 21 and back-up ring 22.

When manipulation shift handle 19 makes selector fork 20 be in the neutral gear position I, since unrestricted from the revolution of turning, so propeller 10 is also done to revolve round the sun around the transmission axis around the axis rotation of propshaft 12 except that doing under dynamic action.But,, do not advance by ship so not understanding front and back because the thrust of propeller is cancelled out each other at circumferencial direction.When selector fork 20 was in positive gear and puts II, it had blocked the positive car bumper pin 2 that is rotating, and has stoped the rotation of turning certainly, and makes the thrust direction of propeller 10 just in time be in the direction that ship is advanced.In like manner, when selector fork goes to when reversing gear the position III, just realized falling back of ship.

On transmission cylinder 8, be welded with the hook 9 that reverses gear,,, and go to support automatically during reversing, form to hang with support and close state, stoped upwarping of Marine outboard motor so during positive car, it leaves support 16 because of it can rotate with transmission cylinder 8.

Pallet 6 is to be hinged on the separable bearing 17, does 360 degree revolutions, can realize turning to of Marine outboard motor by being fixed on the pallet 6 for steering rod, but also forced commutation in case of necessity, and bearing 17 hinges tightly on support 16, can make Marine outboard motor upwarp.

The principle of the application principle of the utility model in hanging peculiar to vessel and the application in Marine outboard motor roughly the same.
