Abstract
The invention provides an engine cylinder sleeve with an inner liner and relates to the technical field of cylinder sleeves of engines. The engine cylinder sleeve with the inner liner comprises a sleeve body and an inner liner connected with the sleeve body, and is characterized in that a conical ring body inner surface is arranged on the upper end of the sleeve body, a conical ring body outer surface matched with the conical ring body on the upper end of the sleeve body is arranged at the upper part of the inner liner, and the conical ring body outer surface of the inner liner is coaxially inlaid in the conical ring body inner surface of the sleeve body. Based on the design in the invention, the conical ring body inner surface on the upper end of the sleeve body can play a good guiding function for the conical ring body outer surface of the inner liner and the inner liner can be axially located in the sleeve body, so that replacement and axial positioning can be realized conveniently and the replacement efficiency and quality can be improved.
Description
Technical field
The present invention relates to the cylinder liner technical field of motor.
Background technique
In the prior art, the cylinder liner of motor is normally formed by the cylinder liner of integral body.In the internal-combustion engine industry, mill cylinder (particularly cylinder liner end mill) is an outstanding generally acknowledged problem.High-performance enginer power is big, and reinforcing degree is higher, and heat load and mechanical load are all higher.Contaminant particles in contaminant particles in the combustion gas and carbon deposit thing (fragile materials) and the lubricant oil will form corrosive wear and abrasive wear at cylinder liner internal wall.Gas leakage can destroy lubricant film, forms many different pressure distribution curves thus---stable and unsettled pressure distribution, and the oil film at this place has only 2.54 microns; If losing oil film can produce the fritter wear trace, the summation of these vestiges is exactly cylinder liner and wear of piston-rings amount, the destruction that the formation of cylinder liner end mill will directly cause sealing system in the cylinder; Oil is scurried in gas leakage to be increased; Oil consumption rises, and power reduces, directly influence diesel engine functional reliability and working life durability.(this is the abrasive wear process that plastic deformation mechanism causes).When cylinder liner end mill amount reaches 0.30 mm, cause group cylinder ring change to change cover, it finally will cause oil consumption excessive (energy waste) and shorten the life-span of motor, has had a strong impact on transportation and has produced, and has caused huge people, thing, financial resources loss.No matter be that the interior surface of cylinder liner of integral body is taked chromium plating, laser hardening, nitrocarburizing; Measures such as plateau honing cross hatches; Still in material, add boron element, P elements, chromium, molybdenum, copper, nickel, titanium alloy etc.; Thereby form various hard phases and (contain boron compound, steadite, titanium eutectic ...) all be in order to improve the wear resistance of cylinder liner.The former improves for making the interior surface of cylinder liner wear resistance, not only paid expensive cost, and case hardening is only at 0.01～0.03mm; Some chromium coating and nitrocarburizing layer also exist makes a concerted effort inadequately or inhomogeneous with bulk junction, and causes peeling off, and nitrocarburizing is made up of chemical combination layer (tapetum and nitride layer, white layer); Its thickness is 0.012～0.030 millimeter, and tapetum accounts for 60%～90%, and nitride layer, white layer accounts for 40%～10%; This tissue is very fragile; So in grinding process, be easy to crackedly, produce abrasive particle on the contrary, enlarged abrasive wear.The latter increases various elements in material, some still is a rare metal, thereby has caused the waste of resource.Therefore, domestic and international internal combustion locomotive expert and manufacturer are all still at the more suitable high-abrasive material of seeking to make cylinder liner.
A kind of cylinder liner with neck bush is arranged, in body, be bumped into neck bush, can bear the friction that various motion produced and the wearing and tearing of piston and piston ring by the neck bush that has; And body is mainly born the cylinder head of motor and the assembling of body; Can improve the working life of product greatly, when the neck bush wear and tear overrun, can only change and provide neck bush for oneself; So not only increased the rub proofness of cylinder liner; Main is to have practiced thrift great deal of raw materials, has practiced thrift the resource and the energy, has improved the environmental protection quality on the whole.
But because body and neck bush are transition fit, inconvenience is changed, and makes troubles to practical application.
Summary of the invention
The object of the invention is to design a kind of air cylinder sleeve of engine with neck bush that makes things convenient for neck bush to change.
The present invention includes body; And the neck bush that is connected with said body; It is characterized in that being provided with conical ring body internal surface in said body upper end; Be provided with the suitable conical ring external surface of conical ring body internal surface with said body upper end on said neck bush top, the said conical ring external surface of said neck bush is coaxial to be bumped in the said conical ring body internal surface of said body.
Because above design, fine leading role is played for the conical ring external surface that conical ring body internal surface can be neck bush in body of the present invention upper end, can realize the neck bush axially locating in body, has made things convenient for replacing and axially locating, can improve and change efficient and quality.
The important meaning of air cylinder sleeve of engine developmental research with neck bush is very big, can select for use composite material to process neck bush, to reach the good overall target of plasticity, toughness, hardness, anti-fatigue performance, impact resistance, thermal conductivity and linear expansion coefficient.
The present invention improves the grade for the performance of the critical component of high-performance enginer.Air cylinder sleeve of engine with neck bush is except improving the quality of products; Also filled up the blank of domestic and international cylinder liner technology; Having increased the rub proofness of the internal surface of the real taking up wear of cylinder liner, is can use for a long time for the cylinder liner ectosome of installing and bear load and make a large amount of functions.Simultaneously, can in maintenance work, save a large amount of more resleeves and increase maintenance expenses, thereby save the material and the energy, can further deepen the wear resistance that improves cylinder liner, save energy and reduce the cost, be beneficial to environmental protection (low-carbon (LC)), life-saving.Realize reducing significantly under the condition of identical output use amount, the power consumption of metallic material, reduce environmental pollution, the remarkable benefit that have energy-conservation, consumption reduction, reduces discharging.For the developing goal of locomotive, automobile, boats and ships cause plays a positive role.
The folder degree of body according to the invention upper end conical ring body internal surface and said neck bush top conical ring external surface and body longitudinal center line be respectively 1 ° 30 '～3 ° 30 '.
The height A of body according to the invention top conical ring body internal surface and said neck bush top conical ring external surface is respectively 1.5%～2% of body height overall.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a D portion enlarged view among Fig. 1.
Embodiment
Like Fig. 1, shown in 2, in body 1, be bumped into neck bush 2.
The outside on the top of neck bush 2 is provided with the conical ring external surface 2-1 that cooperates with conical ring body internal surface 1-1, and the conical ring external surface 2-1 of neck bush 2 axially is bumped in the conical ring body internal surface 1-1 of body 1.
