Abstract
The utility model discloses a surface-copperized air cylinder jacket which comprises a cylinder jacket body, wherein the cylinder jacket body comprises a supporting shoulder, an upper waistband, a cylinder jacket middle water jacket wall, a lower waistband and a cylinder jacket lower skirt, wherein a fire-proof boss and a relief groove are formed on the upper end surface of the cylinder jacket body, and close to the supporting shoulder; a platform reticulated pattern layer subjected to laser quenching are arranged on the internal surface of the cylinder jacket body; and obtuse included angles of reticulated patterns of the platform reticulated pattern layer are 110-130 DEG. The cylinder jacket is simple in structure, high in strength, good in product performance stability, energy-saving, environment-friendly and long in service life, and can perform functions of abrasion resistance, corrosion resistance and deformation resistance in an internal-combustion engine system.
Description
Technical field
The utility model relates to a kind of component of diesel engine, is specifically related to the surface copper cylinder liner of alloy cast iron of the diesel engine assembling of a kind of cylinder diameter φ 75mm.
Background technique
Cylinder liner is as the key components and parts of internal-combustion engine, and its physical dimension and inherent quality are directly determining discharging and the working life of internal-combustion engine.Consider from the technical performance angle, large to the cylinder liner desired strength, hardness is high, wear-resistant, corrosion-resistant, heat distortion amount is little, good airproof performance.And usually require to have the least possible cylinder prepareding gap between the piston, for preventing the fault such as scuffing of cylinder bore, therefore there are higher size and morpheme requirement in each position of cylinder liner.At present, wet liner directly contacts with cooling water because of its outer wall, and outer surface is upper and lower all to be processed with and to protrude waistband to guarantee radial location, has perfect heat-dissipating, cools off uniform characteristics, and favored by the large cylinder liner of domestic each manufacturing enterprise.But, be provided with the water shutoff annular groove on the lower waistband of wet liner, for preventing leaking, on the water shutoff annular groove rubber seal is installed.The design of water shutoff annular groove, the greatly complicated structure of cylinder liner, in use stress is too concentrated to make cylinder liner, the characteristics that existence and stability is poor, frictional force is large, and then cause occurring the phenomenons such as engine knock, swollen cylinder, scuffing of cylinder bore, Fast Wearing, corrosion and seepage, power of IC engine is descended, the shortcoming such as pollution emission severe overweight, noise are large, the increasing combustion engine maintenance expenses, even cause integral body to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of surface copper cylinder liner, and this cylinder liner construction is simple and easy, intensity is high, the product performance good stability, and energy-conserving and environment-protective, long service life in internal-combustion engine system, can play function wear-resistant, corrosion-resistant, resistance to deformation.
For achieving the above object, a kind of surface copper cylinder liner of the utility model, comprise the cylinder sleeve body, described cylinder sleeve body comprises supporting shoulder, upper waistband, cylinder sleeve middle part water jacket wall, lower waistband and cylinder sleeve skirt, fire prevention boss, tool withdrawal groove are arranged on the cylinder sleeve body near the upper-end surface of supporting shoulder, be provided with the platform reticulate pattern through laser hardening on the internal surface of described cylinder sleeve body, the reticulate pattern open bevel of described platform reticulate pattern is 120o ± 10o
In technique scheme, owing to the platform reticulate pattern layer that is provided with on the internal surface of cylinder sleeve body through laser hardening, the surface of platform reticulate pattern layer can keep machine oil cleaner, prolongs the oil exchange cycle, has reduced consumption of lubricating oil; The design of platform reticulate pattern layer increases the actual bearer area of interior surface of cylinder liner, improves air-tightness, has reduced time air displacement, Effective Raise engine power; Machine oil is stored on the surface of platform reticulate pattern floor in the deep valley district, continuous overlapping curve groove is conducive to machine oil and evenly distributes at the cylinder liner working surface, and the top chain-wales is conducive to the formation of high-strength oil film, sufficient lubrication ring wall friction pair, improve the cylinder-barrel surface sliding capability, reduce frictional loss, internal circular surfaces hardness 〉=56HRC, depth of hardening 〉=0.2mm is than long 3 ~ 5 times of common lining life; Do not establish the water shutoff annular groove on the lower waistband, but the water shutoff annular groove is transplanted on the cylinder block, the structure of cylinder liner has been simplified in this design greatly, makes the cylinder liner performance more stable, has eliminated the defective that stress is concentrated.
Description of drawings
Fig. 1 is a kind of surface copper cylinder liner construction of the utility model schematic diagram;
Fig. 2 is the structure enlarged view of platform reticulate pattern layer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing a kind of surface copper cylinder liner of the utility model is described in further detail.
By Fig. 1, Fig. 2 as seen, a kind of surface copper cylinder liner of the utility model, comprise cylinder sleeve body 1, described cylinder sleeve body 1 comprises supporting shoulder 2, upper waistband 3, cylinder sleeve middle part water jacket wall 4, lower waistband 5 and cylinder sleeve skirt 8, fire prevention boss 6, tool withdrawal groove 7 are arranged on cylinder sleeve body 1 near the upper-end surface of supporting shoulder 2, be provided with the platform reticulate pattern layer 9 through laser hardening on the internal surface of described cylinder sleeve body 1, the reticulate pattern open bevel of described platform reticulate pattern layer 9 is 120o ± 10o.
In the present embodiment, cylinder liner this 1, supporting shoulder 2, upper waistband 3, cylinder sleeve middle part water jacket wall 4, lower waistband 5 and cylinder sleeve skirt 8 be through the global copper processing, this internal surface of 1 of cylinder liner improves corrosion-resistant, wear resistance greatly through plasma quenching.Be provided with the platform reticulate pattern layer 9 through laser hardening on the internal surface of cylinder sleeve body 1, have the following advantages: 1, platform reticulate pattern layer surface can keep machine oil cleaner, prolongs the oil exchange cycle, reduced consumption of lubricating oil.2, the common textured surface of actual bearer Area Ratio on the surface of platform reticulate pattern layer improves 5 one 6 times, and the increase of area of contact has improved the air-tightness of piston ring to cylinder hole inwall, has reduced time air displacement, has improved engine power.3, machine oil is stored on platform reticulate pattern floor surface in the deep valley district, continuous overlapping curve groove is conducive to machine oil and evenly distributes at the cylinder liner working surface, and the top chain-wales is conducive to the formation of high-strength oil film, sufficient lubrication ring wall friction pair, improve the cylinder-barrel surface sliding capability, reduce frictional loss, thereby strengthen the oil storage lubricating function, improve useful horsepower.
In the present embodiment, do not establish the water shutoff annular groove on the lower waistband 5, but directly process at cylinder body, infiltrate crankcase by rubber seal 10 isolated cooling circulating waters, make the cylinder liner performance more stable, eliminated the defective that stress is concentrated, improve working life.
