Abstract
The invention discloses a cylinder sleeve which comprises a cylinder sleeve body. The cylinder sleeve body is made of a ceramic material for an alumina-based metallic carbide composite engine; the cylinder sleeve body is a thin-wall spiral reinforcing rib structure; the spiral reinforcing rib structure consists of spiral reinforcing ribs and spiral cooling tanks, which are continuously alternate along the axial direction of the outer surface of the cylinder sleeve; and the outer surface of the cylinder sleeve is also provided with a supporting ring zone. The cylinder sleeve disclosed by the scheme of the invention has compact structure, small volume and light weight; the surface roughness is improved, the combustion of lubricating oil in a cylinder is reduced, the forming of carbonized particles is reduced, and the emission of harmful gas is reduced; and due to the adoption of the ceramic material for the alumina-based metallic carbide composite engine, the performances of hardness, intensity, wear resistance, toughness and the like of the cylinder sleeve are improved, the wear on the cylinder sleeve is reduced, the heat dissipating capacity of the cylinder sleeve is reduced, the temperature of the inner wall of a combustion chamber is risen, and the emission of the harmful gas is reduced.
Description
?
Technical field
The present invention relates to a kind of cylinder liner, belong to technical field of engines.
Background technique
The cylinder liner of using at present adopts alloy cast iron material to process, and structure is the columnar structured of hollow, and this kind structure materials used is many, and cost is high, is prone to deform.Cylinder liner and cylinder head, head gasket and piston constitute the diesel engine work cylinder of sealing, make diesel engine work circulation be able to carry out.Piston set moves reciprocatingly the circulation of finishing the work under the supporting of cylinder and guiding.In diesel engine when work,, the cylinder liner inner chamber receives the effect of pressure of explosion, and washing away of high-temperature fuel gas arranged again, and the high-speed friction of piston, and it is very poor to add lubricating condition, and cylinder liner very easily causes premature wear.Cylinder liner can cause the diesel engine starting difficulty after causing heavy wear, and diesel combustion is bad in the cylinder, black smoke from exhaust, befouling environment.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the cylinder liner that the high heat of a kind of low wearing and tearing is imitated.
Technical solution of the present invention is achieved in that a kind of cylinder liner, comprises the cylinder liner body, and said cylinder liner body adopts aluminium-base metal carbide hybrid engine to process with stupalith; Said cylinder liner body is a thin-walled spiral reinforcing rod structure; Said spiral reinforcing rod structure is made up of the spiral reinforcing rod and the spiral cooling bath that axially replace continuously along the cylinder liner outer surface; Said cylinder liner body surface roughness is 0.25～0.35 μ m.
Preferably, also be provided with the support endless belt on the said cylinder liner outer surface.
Preferably, said cylinder liner body surface roughness is 0.3 μ m.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Cylinder liner of the present invention, compact structure, volume are little, in light weight; Improve surface roughness, reduced the burning of lubricant oil in cylinder, reduced the formation of carbonized particle, reduced discharge of harmful gases; Adopt aluminium-base metal carbide hybrid engine to improve performances such as its hardness, intensity, wear resistance, toughness with stupalith, reduce the wearing and tearing of cylinder liner, reduce the cylinder liner heat dissipating capacity, increase the firing chamber inner wall temperature, reduce discharge of harmful gases.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the plan view of a kind of cylinder liner of the present invention;
Wherein: 1, cylinder liner body; 2, spiral reinforcing rod; 3, spiral cooling bath; 4, support endless belt.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of cylinder liner of the present invention, comprises cylinder liner body 1, and said cylinder liner body 1 adopts aluminium-base metal carbide hybrid engine to process with stupalith; Said cylinder liner body 1 is a thin-walled spiral reinforcing rod structure; Said spiral reinforcing rod structure is made up of with spiral cooling bath 2 spiral reinforcing rod that axially replaces continuously 2 along the cylinder liner outer surface; Said cylinder liner body 1 surface roughness is 0.3 μ m; Also be provided with on said cylinder liner body 1 outer surface and support endless belt 4.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Cylinder liner of the present invention, compact structure, volume are little, in light weight; Improve surface roughness, reduced the burning of lubricant oil in cylinder, reduced the formation of carbonized particle, reduced discharge of harmful gases; Adopt aluminium-base metal carbide hybrid engine to improve performances such as its hardness, intensity, wear resistance, toughness with stupalith, reduce the wearing and tearing of cylinder liner, reduce the cylinder liner heat dissipating capacity, increase the firing chamber inner wall temperature, reduce discharge of harmful gases.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
