Abstract
The utility model discloses a two stroke water -cooling engine cylinder, be in including cylinder body (9), cylinder head (8) and setting ring flange (10) of cylinder body (9) terminal surface (5), its characterized in that: left and right sides wall (14) of ring flange (10) with the outer wall tendency of cylinder body (9) is unanimous. Adopt the utility model discloses a two stroke water -cooling engine cylinder can reduce the weight of cylinder, can also improve the sealed effect between cylinder and the crankcase.
Description
Technical field:
This utility model is related to a kind of two stroke water-cooled engine cylinders, more particularly, to two stroke water of baby plane
Cold engine cylinder.
Background technology:
Existing two stroke water-cooled engine cylinders, its ring flange is arranged on the end face of cylinder block in order to by vapour
Cylinder is connected with crankcase；And existing ring flange is almost along the tetragon of cylinder block outer wall setting, its structure is simple, convenient
Manufacture, and with low cost.
But the ring flange using aforesaid way setting makes the weight of engine cylinder increase, and then makes two stroke water
Cold engine cannot be used on baby plane, in addition, the ring flange of aforesaid way setting also has bad the lacking of sealing effectiveness
Point.
Utility model content:
The purpose of this utility model is to provide a kind of lightweight and good sealing effect two stroke water-cooled engine cylinders.
In order to achieve the above object, this utility model is achieved in that a kind of two stroke water-cooled engine cylinders, including
Cylinder block, cylinder head and the ring flange being arranged on described cylinder block end face it is characterised in that: the left and right sides of described ring flange
Wall is consistent with the outer wall tendency of described cylinder block.Adopt the ring flange of the cylinder arranging in such a way, described gas can be reduced
The total amount of cylinder, and it is more preferable with the connection sealing effectiveness of crankcase to enable to the ring flange of cylinder.Wherein, with engine cylinder
Water inlet side be lower or on, outlet side be up or down, in addition relative to both sides then be the left and right sides.
In order to mitigate the weight of engine cylinder further, the left and right sides wall of described ring flange is and described cylinder block
The concentric circular arc of cylindrical outer wall.
In order to further up to better seal effect, be provided with installing hole at the corner of described ring flange, described
The line of upper and lower two installing holes is tangent with the inner left wall of described ring flange/right side inwall.
In order to be further ensured that the intensity of ring flange and mitigate the weight of ring flange again, the left and right sides wall of described ring flange
Wall thickness is 3-8mm.
In order to further such that described air cylinder structure is more compact, weight is lighter, sealing effectiveness more preferably, described cylinder head and institute
State cylinder block to arrange for integral type.
Using two stroke water-cooled engine cylinders of the present utility model, the beneficial effect that can bring has: 1. can mitigate
The weight of ring flange, and then the weight of cylinder can be mitigated；2. the sealing effectiveness of cylinder and crankcase can be improved；3. can make
Cylinder weight reduction, structure be compacter, sealing effectiveness is more preferable, and then make the weight reduction of the whole machine of electromotor.
Brief description:
Fig. 1 is the front view of engine cylinder in this utility model embodiment；
Fig. 2 is the upward view of Fig. 1.
Specific embodiment:
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail, but this utility model
It is not limited to these embodiments, the improvement on any essence spirit in the present embodiment or replacement, still fall within this utility model
Claim scope required for protection.
Embodiment: as depicted in figs. 1 and 2, a kind of two stroke water-cooled engine cylinders, including cylinder block 9, cylinder head 8 with
And it is arranged on ring flange 10, the left and right sides wall 14 of described ring flange 10 and the described cylinder block 9 of described cylinder block 9 end face 5
Outer wall tendency is consistent.Wherein, with water inlet 3 side of engine cylinder for lower or on, outlet 4 side be up or down, in addition
Relative both sides are then the left and right sides.
Preferably, the left and right sides wall 14 of described ring flange 10 is the circle concentric with the cylindrical outer wall of described cylinder block 9
Arc.
And, it is provided with installing hole 11, i.e. screw thread via, described upper and lower two spiral shells at the corner of described ring flange 10
The line of stricture of vagina via is tangent with the inner left wall/right side inwall of described ring flange 10.
Wherein, left and right sides wall 14 wall thickness of described ring flange 10 is 3-8mm.Can select but be not limited to 3mm, 4mm,
5mm、6mm、7mm、8mm.In the present embodiment, left and right sides wall 14 thickness of preferably ring flange 10 is 5mm.
And, described cylinder head 8 and described cylinder block 9 are arranged for integral type.Described cylinder head 8 and cylinder block 9 can be
Integrated casting, integrated forging molding or other integrated molding mode, in the present embodiment, preferably cylinder head
8 and the integrated casting of cylinder block 9.
Using the two stroke water-cooled engines of the present embodiment, when mounted, first by the spiral shell of ring flange 10 upside or downside
Stricture of vagina via is connected with crankcase, then the screw thread via of described ring flange 10 downside or upside is connected with crankcase, such energy
Enough make ring flange 10 more preferable with the sealing effectiveness of crankcase, and the ring flange 10 in the present embodiment decreases to greatest extent
The weight of ring flange in turn ensure that the intensity of ring flange.Further such that the weight of cylinder reduces.And by cylinder head 8 and cylinder
The integrated casting of body 9, can reduce the weight of cylinder, make cylinder structure more compact, sealing effectiveness is better.Further
Make the weight of electromotor lighter, sealing effectiveness is more preferable, more compact structure, is more applicable on baby plane.
