Description

Swinging is hung the oar machine

Technical field

The utility model relates to a kind of swinging and hangs the oar machine, especially a kind of hull afterbody that is installed in, and the power of supporting driving engine output passes to screw propeller by driving system, and the swinging that promotes ship motion is hung the oar machine.

Background technology

At present, known extension oar machine generally is divided into mechanical type and fluid pressure type, and fluid pressure type is hung the oar machine and generally is applied to large ship, and mechanical type is hung the oar machine and is used for spitkit more.Fluid pressure type is hung oar machine complex structure, and its manufacturing, maintenance and use are all more loaded down with trivial details, and operating personal is required height, and mechanical type extension oar machine is simple in structure, and processing ease is applicable to small hull, uses unrestricted.Yet, now the mechanical type on the market hang the oar machine with outer shaft and axle sleeve as one, its maintenance and installation are complicated, in addition, the lower box that present mechanical type is hung the oar machine can not rotate, hull has improved the cost of hanging the oar machine like this if need change of direction just to need the additive incrementation engine installation, has increased the consumption of the energy.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and this extension oar machine has not only been realized the commutation of employing nowel blade, and low cost of manufacture, keeps in repair swinging easy to use and hangs the oar machine.

In order to achieve the above object, the technical solution adopted in the utility model is: go up box assembly and comprise connection disc type belt pulley, the top box main shaft, first gear, second gear, top box, last short sleeve, the outer shaft bearing, oil sealing, lower end axle sleeve bearing, transmission shaft and the 3rd gear, the top box spindle nose is equipped with and connects the disc type belt pulley, first gear is loaded on the position, intermediate portion, top box is equipped with in the outside, the transmission shaft top and bottom are equipped with second gear and the 3rd gear respectively, suit lower end axle sleeve bearing on it, axle sleeve bearing outside, lower end is with short sleeve, and be spirally connected with top box, outer shaft bearing and oil sealing connect and are loaded on the short sleeve, following box assembly comprises spindle arm, outer shaft, the setting-out plate, the lower end axle sleeve, nowel, the 4th gear, nowel main shaft and blade, nowel main shaft one end is equipped with blade, and the 4th gear is equipped with in the centre, and nowel is set in its outside, and be spirally connected with the lower end axle sleeve, be welded with the setting-out plate on the axle sleeve of lower end, its top is connected to outer shaft, is welded with spindle arm and jacking system on the outer shaft.

The utility model has the advantages that:

Compact conformation, reasonable in design, this extension oar machine have not only been realized employing nowel blade commutation, and low cost of manufacture, keep in repair easy to use, the saving energy.

Description of drawings

Fig. 1 is the utility model structural representation;

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, box assembly comprises connection disc type belt pulley 8 on the utility model, top box main shaft 9, first gear 10, second gear 11, top box 12, last short sleeve 13, outer shaft bearing 6, oil sealing 18, lower end axle sleeve bearing 5, transmission shaft 19 and the 3rd gear 16, top box main shaft 9 ends are equipped with and are connected disc type belt pulley 8, first gear 10 is loaded on the position, intermediate portion, top box 12 is equipped with in the outside, transmission shaft 19 top and bottom are equipped with second gear 11 and the 3rd gear 16 respectively, suit lower end axle sleeve bearing 5 on it, axle sleeve bearing 5 outsides, lower end are with short sleeve 13, and be spirally connected with top box 12, outer shaft bearing 6 and oil sealing 18 connect and are loaded on the short sleeve 13, following box assembly comprises spindle arm 14, outer shaft 7, setting-out plate 15, lower end axle sleeve 4, nowel 3, the 4th gear 17, nowel main shaft 2 and blade 1, nowel main shaft 2 one ends are equipped with blade 1, the 4th gear 17 is equipped with in the centre, nowel 3 is set in its outside, and be spirally connected with lower end axle sleeve 4, be welded with setting-out plate 15 on the lower end axle sleeve 4, its top is connected to outer shaft 7, is welded with spindle arm 14 and jacking system 20 on the outer shaft 7.

Described outer shaft bearing 6 can be an axle sleeve.

The connection mode of described outer shaft 7 and lower end axle sleeve 4 can be for being spirally connected or welding.
