Abstract
The utility model discloses a single-cylinder air-cooled diesel engine body, comprising an engine body and a cylinder liner; a cylinder liner hole is arranged in the engine body; mutually corresponding circumferential positioning steps are arranged on the outer wall of the cylinder line and the inner wall of the cylinder liner hole; the cylinder liner is pressed in the cylinder liner hole in a hot press way; the positioning steps realize the axial positioning between the cylinder liner and the cylinder liner hole; a plurality of axial convex ribs are arranged on the outer wall of the cylinder liner; and concave slots are arranged on the inner wall of the cylinder liner hole, corresponding to the convex ribs. The convex ribs and the concave slot structures realize the radial positioning between the cylinder liner and the cylinder liner hole to prevent the cylinder liner rotating in the hole. The cylinder liner and the engine body are formed through hot press and can be separated under certain temperature conditions. When the cylinder liner needs to be replaced, the cylinder liner can be simply separated from the engine body and then separately replaced, and the engine body can be continuously used; therefore, such an engine structure can significantly reduce the maintenance costs.
Description
Technical field
The utility model relates to single-cylinder air-cooled diesel engine, specifically refers to a kind of single-cylinder air-cooled diesel engine body, and cylinder sleeve and the hot pressing of body body form in this body, and is conveniently replaced when needed.
Background technique
Cylinder sleeve is one of complicated and the most abominable parts of working environment in the motor, and piston is made the high speed linear reciprocating motion within it, and it is under the condition of high temperature, high pressure works, and lubricating condition is poor, and the gas after the burning has certain corrosive action again.Just because of this, it also is parts that break down easily, breaks down and can only change usually.But the single-cylinder air-cooled diesel engine of the logical mechanomotive force of existing conduct is because cylinder sleeve and body are to form by the die casting heat seal, and cylinder sleeve combines the back and forms an integral body with body, and inseparable, in a single day cylinder sleeve breaks down and can only change together with body.About 300 yuan, independent cylinder sleeve is then less than 30 yuan usually for the price of body, and the mode of this integral replacing is the maintenance cost height not only, can cause very big economic loss, and forms the great wasting of resources.
The model utility content
At the prior art above shortcomings, the purpose of this utility model provides the single-cylinder air-cooled diesel engine body that a kind of cylinder sleeve and body can separate.
The technical solution of the utility model is achieved in that a kind of single-cylinder air-cooled diesel engine body, comprise body body and cylinder sleeve, be provided with sleeve port in the body body, it is characterized in that: described outer wall of cylinder jachet and sleeve port inwall are provided with the circumferential positioning step of mutual correspondence, and cylinder sleeve press-fits in sleeve port with hot pressing mode.Positioning step is realized both axially locating.
Further, described outer wall of cylinder jachet is provided with some axial convex tendons, and the sleeve port inwall is provided with and the convex tendon corresponding groove.Convex tendon and groove structure are realized both radial locations, prevent that cylinder sleeve from rotating in the hole.
Therefore the utility model can separate under certain temperature condition because cylinder sleeve and body form by hot pressing.When cylinder sleeve need be changed, just can only need cylinder sleeve is told from body, to change cylinder sleeve more separately and get final product, body then can continue to use, so this housing construction can reduce maintenance expenses greatly, once reduces to less than 30 yuan by former 300 yuan.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, from the figure as can be seen, single-cylinder air-cooled diesel engine body of the present utility model, comprise body body 1 and cylinder sleeve 2, be provided with sleeve port in the body body, described cylinder sleeve 2 outer walls and sleeve port inwall are provided with the circumferential positioning step 3 of mutual correspondence, and cylinder sleeve 2 press-fits in sleeve port with hot pressing mode.Positioning step is realized both axially locating.Simultaneously be provided with some axial convex tendons 4 at cylinder sleeve 2 outer walls, axially convex tendon 4 equidistantly distributes along circumference, and the sleeve port inwall is provided with and the convex tendon corresponding groove.Convex tendon and groove structure are realized both radial locations, prevent that cylinder sleeve from rotating in the hole.Certainly, also can establish axial notch at outer wall of cylinder jachet, the sleeve port inwall is established corresponding convex tendon.
Described cylinder sleeve 2 inwall lower ends carry out chamfered 5 so that cylinder sleeve separately.During fractionation, place the fluid medium to be heated to the temperature that to separate together body and cylinder sleeve, insert in the cylinder sleeve lower end by special separation utensil then, this separation utensil has the tapering corresponding with the cylinder sleeve chamfering, cylinder sleeve can be told from body by impacting the separation utensil.The principle that this chamfering exists realizes that with aforementioned positioning step the principle of cylinder sleeve and sleeve port axially locating is the same, so chamfered also can be a ledge structure.
