Abstract
The utility model discloses an internal combustion engine cylinder sleeve, comprising a sleeve body, wherein a reinforcing sleeve and an anti-wear layer are sequentially arranged on the outer wall of the sleeve body from inside to outside; reinforcing rings are arranged between the reinforcing sleeve and the anti-wear layer and are uniformly distributed along the height direction of the sleeve body; and adjacent reinforcing rings form heat dissipation passages. The reinforcing sleeve of the internal combustion engine cylinder sleeve can effectively increase the pressure-resistant performance of the cylinder sleeve; the adjacent reinforcing rings form the heat dissipation passages, so that the heat dissipation performance of the sleeve wall of the sleeve body is improved; and the anti-wear layer reduces the loss of the sleeve body during installation, so that the phenomena of deformation and out of circularity in use are reduced.
Description
Technical field
The utility model relates to a kind of internal combustion machine part, relates in particular to a kind of cylinder of internal combustion engine sleeve.
Background technique
Present cylinder sleeve great majority are alloy cast steel materials, because inwall and the outer surface of sleeve are hard material, when the maintenance power engine, need sleeve could be got in the mounting hole of cylinder sleeve with powerful pressure, and because mounting hole in use all can deform, lose round phenomenon, after being subjected to powerful pressure extrusion and entering, cylinder sleeve also can lose round metaboly with mounting hole, existing cylinder sleeve wear resistance and thermal diffusivity are relatively poor simultaneously, inefficiency.
The model utility content
At the problem that above-mentioned prior art exists, the utility model provides a kind of cylinder of internal combustion engine sleeve.
To achieve these goals, the technical solution adopted in the utility model is: a kind of cylinder of internal combustion engine sleeve, comprise cylindrical shell, the outer wall of cylindrical shell is provided with strengthening sleeve and wearing course from inside to outside successively, be provided with stiffening ring between strengthening sleeve and the wearing course, stiffening ring evenly distributes along the short transverse of cylindrical shell, and adjacent stiffening ring forms heat dissipation channel.
As preferably, the thickness of wearing course is 1 ~ 3mm.
Compared with prior art, advantage of the present utility model is: strengthening sleeve can effectively increase the withstand voltage properties of cylinder sleeve, adjacent stiffening ring forms heat dissipation channel, improved the barrel heat dispersion of cylindrical shell, when reducing installation, wearing course to the loss of cylindrical shell, reduced the generation of in use being out of shape, losing the circle phenomenon.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, cylindrical shell; 2, strengthening sleeve; 3, stiffening ring; 4, wearing course.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of mode of execution of the present utility model, consult Fig. 1 and Fig. 2, the utility model comprises cylindrical shell 1, the outer wall of cylindrical shell 1 is provided with strengthening sleeve 2 and wearing course 4 from inside to outside successively, be provided with stiffening ring 3 between strengthening sleeve 2 and the wearing course 4, stiffening ring 3 evenly distributes along the short transverse of cylindrical shell 1, and adjacent stiffening ring 3 forms heat dissipation channel.The thickness of wearing course 4 is 1 ~ 3mm.
In the using process, strengthening sleeve 2 can effectively increase the withstand voltage properties of cylinder sleeve, and adjacent stiffening ring 3 forms heat dissipation channel, has improved the barrel heat dispersion of cylindrical shell 1, when reducing installation, wearing course 4 to the loss of cylindrical shell 1, reduced the generation of in use being out of shape, losing the circle phenomenon.
Although be that a most practical and preferred embodiment has been described the utility model in conjunction with current taking as, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended to contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims on the contrary.
