Wherein, 1 it is U-shaped breach, 2 be trapeze cut, 3 is milling plane.
Embodiment
Core of the present utility model there is provided a kind of cylinder jacket, reduces the volume of engine, realizes engine
Lightweight.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-Fig. 3 is refer to, the utility model embodiment provides a kind of cylinder jacket, and the barrel of cylinder jacket connects close to piston
One end of bar sets jagged, and breach is U-shaped breach 1, v-notch or ladder type breach 2, and breach is located at piston rod reciprocally swinging
Path on, passed through for piston rod.
The cylinder jacket reduces the interference effect that cylinder jacket is moved to piston rod due to being provided with breach, increase
Piston rod movement angle, reduces engine matrix and connecting rod axial length 5-50mm, shortens engine height, reduces
Engine volume, alleviates the weight of engine, so as to reduce engine consumption.
Further, when breach is U-shaped breach 1, the outer end of U-shaped breach 1 is flaring structure, as shown in Fig. 1, so that
Interference of the breach outer end to piston rod is avoided, while meeting the structural strength of cylinder jacket.It is of course also possible to be not provided with enlarging knot
Structure, but the width of the U-shaped breach of increase.
Further, in the present embodiment, breach is arranged on the one or both sides of the outer tube wall of cylinder jacket, is connected according to piston
The swing angle of bar and position select the set location and quantity of breach.
In order to further reduce the size of engine, in the present embodiment, relative gas is provided with the cylindrical wall of cylinder jacket
A pair of milling planes 3 of the axisymmetrical of cylinder sleeve, the vertical line of the process bore axis of milling plane 3 and the process cylinder of breach
The vertical line of set axis is mutually perpendicular to.That is milling plane 3 and breach is set not in the homonymy of cylinder jacket in 90 °.By setting
Milling plane 3, then when cylinder jacket is assemblied in engine matrix, the milling plane 3 of two neighboring cylinder jacket can be with parallel tight
Neighbour is set, because milling plane 3 is to carry out milling in cylindric cylinder-barrel surface to obtain, therefore, a pair of milling planes 3 it
Between distance be less than cylinder jacket external diameter, so as to reduce the arrangement length of multiple cylinder jacket, that is, reduce engine crankshaft side
To length, each cylinder jacket can shorten 0.5~5mm.By setting milling plane 3 to further reduce the chi of engine
It is very little, the volume of engine is reduced, while cylinder jacket own wt reduces, so as to alleviate the overall weight of engine.
In the present embodiment, the outer surface of cylinder jacket is provided with the projection of random distribution, and projection is the casting formed after casting
Projection is made, the bond strength of cylinder jacket and engine matrix can be strengthened.
In the present embodiment, the outer surface of cylinder jacket can also be flank or spray-coating surface, or different surfaces structures
Combination.
Specifically, the preparation method of the cylinder jacket in the present embodiment is：By carrying that horizontal centrifugal cast tube casting machine is produced
Raised blank entered after processing, was machined out step 1：Monomer blank is cut off, the long pipe fittingses hair that centrifugal casting is produced
Base carries out cutting process, obtains shorter monomer part.
Machining steps 2：Endoporus processing and forming, it is fixed by three-jaw automatic fixture clamped one time using vertical machining centre
The monomer blanking inner hole and end face that position produces machining steps 1 are processed.
Machining steps 3：Fine turning outer circle, using horizontal Machining centers, is added machine by automatic endoporus clamping device clamping
The periphery that work step rapid 2 is produced carries out turnery processing, and milling exhaust hood set outer surface roughness is Ra6.3, and outside diameter runout is small
