Abstract
The invention discloses an outboard engine with a cooling assembly, which includes a cooling assembly, and the cooling assembly includes an engine drive shaft, an impeller, a water pump liner, an underwater device and a water pipe, wherein the water pump liner is arranged in the underwater device; the water pump liner is communicated with the underwater device; an eccentric orifice is formed on the water pump liner; the engine drive shaft penetrates through the eccentric orifice; the impeller is arranged on the engine drive shaft and in the cavity of the water pump liner; a water outlet is arranged on the water pump liner adjacent to the eccentric orifice; the outer radius of the impeller is greater than the biggest distance from the center of the eccentric orifice to the inner wall of the water pump liner; the impeller is as thick as the inner cavity of the water pump liner; the water outlet is connected with one end of the water pipe; and the other end of the water pipe is connected with the engine. The thickened impeller and the water pump liner increase the water flow of the cooling device and reduce the engine temperature rise, so as to further improve the engine efficiency and prolong the service life of the engine.
Description
Technical field
The present invention relates to a kind of outboard machine motor, particularly a kind of device is simple more, cooling effect better with the outboard machine motor of cooling package, belongs to the outboard machine technical field of engines.
Background technique
Outboard machine is a mean engine in the hull outside, or directly is soaked in the water, or on the water surface, is used for small volume hulls such as yacht more, like the ship of fishing above the rivers, rubber dinghy etc., is common in river, the intensive area of lake fishery; The motor of outboard machine generally adopts the method for water-cooled to cool off, and promptly through feedway near the water the hull is transported to the heat that absorbs motor in the cooling unit on the motor, hot water is discharged again; But the water cooling in prior technology device generally all is the external device on the outboard machine, and manufacture cost is high, and comparatively complicated; And the water yield of water receiving device for cooling transmission is too small in the outboard machine, does not reach good cooling effect.
Summary of the invention
The present invention seeks to provide that a kind of device is simple more for the deficiency that overcomes existing technology, cooling effect is better with the outboard machine motor of cooling package.
For achieving the above object, the technological scheme that the present invention adopts is: a kind of outboard machine motor with cooling package, comprise cooling package, and said cooling package comprises engine-driving axle, impeller, water pump inner bag, underwater units, water pipe; Said water pump inner bag is arranged in the underwater units; Said water pump inner bag is communicated with outward with underwater units; Said water pump inner bag is provided with eccentric opening; Said engine-driving axle passes said eccentric opening; Said impeller is arranged on the engine-driving axle and is positioned at the cavity of water pump inner bag; Position near eccentric opening on the said water pump inner bag is provided with water outlet; The outer radius of said impeller is greater than the center of the eccentric opening ultimate range to the inwall of water pump inner bag, the inner chamber consistency of thickness of the thickness of impeller and water pump inner bag; Said water outlet is connected with an end of water pipe; The other end of said water pipe links to each other with motor.
Preferably, the inner chamber consistency of thickness of the thickness of said impeller and water pump inner bag, and greater than 20 millimeters.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The outboard machine motor of the present invention program's band cooling package; Comprise the impeller and the water pump inner bag that are connected with the engine-driving axle; The motor that is arranged so that outboard machine is like this worked at the beginning, and the constituent of motor will start automatically and carry out water delivery, and motor is cooled off; The impeller and the water pump inner bag of thickening make that the water flow of this cooling unit is bigger, and the temperature rise of motor is lower, and then has improved the efficient of motor, the working life of also having improved motor simultaneously; And the cooling unit production of this outboard machine motor simple and fast that gets up, greatly reduce the cost of production of outboard machine, and improved manufacturing efficiency.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the sectional view of cooling package of the outboard machine motor of band cooling package of the present invention;
Accompanying drawing 2 is the plan view of water pump inner bag and impeller in the cooling package of outboard machine motor of band cooling package of the present invention;
Wherein: 1, engine-driving axle; 2, impeller; 3, water pump inner bag; 4, underwater units; 5, water pipe; 6, water outlet.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
The outboard machine motor of the present invention program's band cooling package; Comprise the impeller and the water pump inner bag that are connected with the engine-driving axle; The motor that is arranged so that outboard machine is like this worked at the beginning, and the constituent of motor will start automatically and carry out water delivery, and motor is cooled off; The impeller and the water pump inner bag of thickening make that the water flow of this cooling unit is bigger, and the temperature rise of motor is lower, and then has improved the efficient of motor, the working life of also having improved motor simultaneously; And the cooling unit production of this outboard machine motor simple and fast that gets up, greatly reduce the cost of production of outboard machine, and improved manufacturing efficiency.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
