Abstract
The utility model relates to a hanging machine vertically and in series mounted propulsion device for a small horse power boat, which comprises a connecting shaft, a bossing, a big and a small spiral bevel gear, a vertical shaft, an outer hollow stern shaft, an inner solid stern shaft, two propellers, etc. A stern diesel engine drives the vertical shaft to rotate through a belt pulley and the connecting shaft; the vertical shaft is respectively connected with the outer hollow stern shaft and the inner solid stern shaft through the big and the small spiral bevel gears, and the end parts of the latter two are respectively provided with a propeller. Driven by the diesel engine, the two propellers rotate oppositely with the same speed; affected by the bossing, the water propelled backward appears straight. The utility model has the advantages of a high speed, a simple structure, and easy fabrication; the navigation speed is increased.
Description
The utility model belongs to marine propulsion.
At present, the fraction horsepower ship all is equipped with propelling unit.The propelling unit of using generally has only a propelling unit now, is contained on the stern by diesel-engined drive.This is equipped with single angle of rake propelling unit and can't meeting the demands aspect the quickening speed of a ship or plane.
The purpose of this utility model is to provide a kind of two angle of rake propelling units that are equipped with, with the angle of rake propelling unit of existing list relatively, in same voyage, with horsepower, condition with ship shape under, the speed of a ship or plane improves 12%.
Accompanying drawing 1 is an external form scheme drawing of the present utility model, and Fig. 2 is a twin screw structural representation of the present utility model.1 connects axle in the accompanying drawing, 2 flanges, 3 rudders, 4 change speed gear boxs, 5 horizontal shafts, 6 propelling units, 7 streamlined reefer housings, 8 small spiral bevel gears, 9 vertical axises, 10 king bolt bevel gears, 11 external hollow stern tube shafts, 12 interior solid stern tube shafts.The utility model is by the diesel-engined drive that hangs over stern.The transmission shaft of diesel engine is received on the axle 1 by belt pulley, vertical axis 9 connects axle 1 spline therewith and connects, small spiral bevel gear 8 and king bolt bevel gear 10 are equipped with in the bottom of vertical axis 9, the former is last, the latter is following, between this two screw bevel gear certain distance is arranged, the small spiral bevel gear engagement of interior solid stern tube shaft 12 left ends of the former and horizontal positioned, the king bolt bevel gear of the latter and external hollow stern tube shaft 11 left ends meshes.The two small spiral bevel gear numbers of teeth are identical, and 26～28 teeth can be arranged; The number of teeth of two king bolt bevel gears is also identical, can be about 36 teeth.Interior solid stern tube shaft 12 is in the inside of external hollow stern tube shaft 11, and the two axial line overlaps, and its right-hand member is respectively adorned a propelling unit 6.Because in two screw bevel gears of vertical axis 9 lower ends, up install on one " umbrella top ", down install on another " umbrella top ", so during two propelling units of diesel-engined drive, can make that its work is fast relatively together to be rotated.This two angle of rake distance should be as much as possible little, so just can more effectively increase the speed of a ship or plane.Two propelling units are close and do speed rotation relatively together, under the effect of its exterior circular streamlined reefer housing 7, make linearly shape of its current of pushing the rear to, and speed are very fast, and this more helps increasing ship's speed.
The utility model manufacturing simple in structure, easy, the ship speed of a ship or plane is fast during use.
Claims (1)
- A kind of fraction horsepower Marine outboard motor is vertically gone here and there the dress propelling unit, it is characterized in that it forms by meeting axle 1, streamlined reefer housing 7, king bolt bevel gear 10, small spiral bevel gear 8, vertical axis 9, external hollow stern tube shaft 11, interior solid stern tube shaft 12 and two institutes such as propelling unit 6; Wherein vertical axis 9 with connect the axle 1 spline be connected, small spiral bevel gear 8 and king bolt bevel gear 10 are equipped with in the former bottom, small spiral bevel gear 8 is above king bolt bevel gear 10, certain distance is arranged between the two, small spiral bevel gear 8 meshes with the small spiral bevel gear of interior solid stern tube shaft 12 left ends of horizontal positioned, and the number of teeth of this a pair of small spiral bevel gear is identical; King bolt bevel gear 10 meshes with the king bolt bevel gear of external hollow stern tube shaft 11 left ends, and the number of teeth of this a pair of king bolt bevel gear is also identical; Interior solid stern tube shaft 12 is in the inside of external hollow stern tube shaft 11, both axial lines overlap, and its right-hand member respectively is equipped with a propelling unit 6, small spiral bevel gear 8 on vertical axis 9 " umbrella top " is down installed, king bolt bevel gear 10 " umbrella top " is up installed, and circular streamlined reefer housing 7 is two angle of rake outsides.
