Abstract
The invention relates to a starting engine with a labyrinth drainage mechanism. The starting engine comprises a starting engine shell. A rotor and a stator are arranged in the starting engine shell, and the rotor is wrapped by a drive cover. The starting engine is characterized in that a drainage outlet is formed in the bottom of the starting engine shell, and a drainage duct structure in the drainage outlet is in a multilayer circuitous shape. The starting engine is simple in structure, and can be effectively used for preventing impurities from entering the starting engine shell in the drainage process of the starting engine, so that the starting engine can be effectively protected.
Description
Technical field
The present invention relates to a kind of drainage mechanism, specifically, relate to a kind of starter motor with mazy type drainage mechanism.
Background technique
Starter motor is again motor, and it is mechanical energy by the electric energy conversion of storage battery, drives engine flywheel rotation to realize the startup of motor.Starter motor is divided into direct current starter motor, gas starter motor, pneumatic starter etc. according to working principle.On internal-combustion engine mostly adopt be direct current starter motor, be characterized in compact structure, simple to operate and be convenient to safeguard.Gas starter motor is a kind of miniature gasoline engine with clutch and gear, and power is large and affected by temperature less, can starting large internal-combustion engine, and be applicable to severe cold areas.Pneumatic starter is divided into two classes, and one is that pressurized air is squeezed into cylinder according to job order, and one is to use pneumatic motor to drive flywheel.The purposes of pneumatic starter, close to gas starter motor, is generally used for the starting of large combustion machine.
But existing starter motor there will be waterflooding while working onboard, particularly southern rainy weather condition, water inlet in starter motor, if water will not eliminating can cause starter motor early failue for a long time in starter motor, and existing starter motor bottom is equipped with drain opening, but the discharge channel structure in existing drain opening is straight line type, when vehicle is in the time that the road conditions of jolting are travelled, foreign material are easy to enter in starter housing by drain opening, cause the fault of motivation.
Summary of the invention
The present invention is directed to the irrational defect of drain opening design organization in existing starter motor, provide a kind of starter motor with mazy type drainage mechanism to address the above problem.
The solution of the present invention is by such realization: a kind of starter motor with mazy type drainage mechanism, comprise starter housing, in described starter housing, be provided with rotor and stator, described rotor is driven lid parcel, described starter housing bottom position is provided with drain opening, and the discharge channel structure in described drain opening is Multilayer bypass shape.
General plotting of the present invention is: change the structure of easily entering foreign material in the drain opening of starter motor bottom, adopt the discharge channel structure of Multilayer bypass shape, conveniently discharge liquid water and prevent that hard foreign material from entering the function of discharge channel thereby realize.
In the present invention, in order to make discharge channel in drain opening can realize the roundabout design of many structures, therefore, need to carry out dilatation to driving lid, therefore, as preferred version, driving and covering external profile diameter is 70mm-80mm, and in this size, design makes the roundabout design of drainage pipe can meet the requirement of present starter motor.
In the present invention, as optimal case, the discharge channel structure in described drain opening is " second " word shape.The discharge channel structure of this structure, can be directly disposable by die cast, and fabricating cost is minimum.
In the present invention, as preferred version, the diameter of described discharge channel is 5mm-8mm, and the discharge channel in this diameter can effectively be carried out draining, and prevents that foreign matter from entering.
Substantive distinguishing features of the present invention and progress are:
1. the present invention is simple in structure, and passable is effective in to the process of starter motor draining, prevents that foreign material from entering in starter housing, thereby can play the effect of effective protection starting machine.
2. the present invention makes simply, can adopt stamping forming technique to realize,
3. the present invention is simple in structure, is convenient to apply in industry.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention one;
Fig. 2 is the structural representation of discharge channel in the embodiment of the present invention one;
Component title and sequence number in figure:
Starter housing 1, drive cover 2, stator 3, drain opening 4,
Discharge channel 4.1.
Embodiment
Describe the present invention below in conjunction with drawings and Examples, following examples explain with invention optimal effectiveness.
Embodiment 1:
As shown in Figure 1-2, this has the starter motor of mazy type drainage mechanism, comprise starter housing 1, in described starter housing 1, be provided with rotor and stator 3, rotor is driven covers 2 parcels, is provided with drain opening 4 at starter housing 1 bottom position, discharge channel 4.1 structures in drain opening 4 are " second " word shape, in the present embodiment, driving and covering external profile diameter is 70mm, and the diameter of discharge channel 4.1 is 5mm.
Embodiment 2:
In the present embodiment, difference from Example 1 is, described discharge channel 4.1 structures are roundabout shape, similar roundabout labyrinth state, and driving and covering external profile diameter is 80mm, the diameter of discharge channel 4.1 is 8mm.All the other working principles or structure are identical with embodiment 1
Finally be noted that external profile diameter is covered in above-mentioned driving and discharge channel diameter is preferred version, can reach the anti-impurity effect of beyond thought draining.
Obviously, above-described embodiment is only used to clearly illustrate example of the present invention, and not to the restriction of implementing.For the those of ordinary skill in described field, can also make other changes in different forms on the basis of the above description.Here without also cannot be to all mode of execution with exhaustive.And the apparent variation of being amplified out thus or variation are still among protection scope of the present invention.
Claims (4)
1. one kind has the starter motor of mazy type drainage mechanism, comprise starter housing, in described starter housing, be provided with rotor and stator, described rotor is driven lid parcel, it is characterized in that: described starter housing bottom position is provided with drain opening, the discharge channel structure in described drain opening is Multilayer bypass shape.
2. the starter motor with mazy type drainage mechanism according to claim 1, is characterized in that: described in drive that to cover external profile diameter be 70mm-80mm.
