Description
Technical field
The utility model belongs to cylinder sleeve technology field, in particular to a kind of cylinder jacket escape profiling finish rolling hardening rolling
Wheel.
Background technique
The advantages that internal combustion engine is good with its mobility, dyestuff good economy performance, use scope is wide is as the main dynamic of ship
Power, and cylinder jacket and piston ring are all that most important friction is secondary in internal combustion engine, directly affect the service life and property of internal combustion engine
It is tender.Cylinder jacket is that the component part of combustion chamber components is directly contacted with piston ring again, periodicity of the inner wall by high-temperature fuel gas
Heat effect, outer wall are directly contacted with cooling water, subject cavitation pitting caused by cylinder jacket high-frequency vibration and electrolyte corrosion.?
Such high temperature, high pressure and have under the harsh conditions such as solid particle and corrosive medium insufficient lubrication, and various mills easily occur for cylinder jacket
Damage, and the service life of internal combustion engine and service performance depend on this abrasion resistance secondary to friction in very great achievement surely.
Kernel component of the cylinder jacket as engine operation, withdrawing groove location fatigue fracture are that one kind of cylinder jacket is fatal
Failure mode, catastrophic destruction will be caused to engine, how to improve the fatigue crack-resistant energy of cylinder jacket withdrawing groove location
Power is the project that cylinder jacket manufacturing enterprise is studied always.
There are many cylinder-barrel surface intensifying method at this stage, but most of is the working process before cylinder jacket is installed and used, benefit
With spraying, the methods of nitridation is made certain thickness strengthening layer in interior surface of cylinder liner, plays wear-resisting effect.
But in use, once strengthening layer is worn, cylinder liner abrasion speed sharply accelerates, so that the energy, material
Material waste is more.There is lubricant of the addition with self-lubricating self-repair function solid particle in lubricating oil at present, so that cylinder
Set carries out selfreparing to the cylinder jacket after abrasion in use, but due to the finiteness of additive and is unevenly distributed
Property, harsher to some environment, wearing more serious position cannot be guaranteed its effective selfreparing, even if being also after repairing
The reparation of single still will cause the significant wastage of material after the time is longer.Moreover, the above method has biggish dirt to environment
It dye or needs to invest costly, there is certain undesirable property.Therefore, the wearability of cylinder-barrel surface how is improved
As urgent problem to be solved.
Summary of the invention
The purpose of this utility model is the deficiency for current above-mentioned technology, provides a kind of cylinder jacket escape profiling rolling
Strengthen idler wheel, improves cylinder jacket withdrawing groove location fatigue crack-resistant ability.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of cylinder jacket escape profiling finish rolling hardening idler wheel, including roller body, the roller body include that both ends are set
The arc rolling portion set and middle part pass through cone connection through the centre bore being arranged, and between arc rolling portion and centre bore and connect
It connects, the radius in arc rolling portion and the radius equivalent setting of escape to be processed.
The hardness in arc rolling portion is HRC60 ~ HRC65.
The hardness in arc rolling portion is HRC62.
Arc rolling portion, centre bore and cone connection are using integrated molding setting.
The beneficial effects of the utility model are:
The cylinder jacket escape profiling finish rolling hardening idler wheel, by both ends arc rolling portion and for being connect with rolling mechanism
Centre bore setting, and the radius equivalent setting of the radius in arc rolling portion and escape to be processed protects in the rolling process
Escape circular arc position whole stress is demonstrate,proved, it is consistent for the finish rolling hardening uniform in effect of cylinder jacket withdrawing groove location, it effectively improves
Finish, surface hardness and the surface compact degree of withdrawing groove location play raising rolling position fatigue crack-resistant ability great
Improvement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the machining sketch chart of the utility model.
Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
The utility model provides a kind of cylinder jacket escape profiling finish rolling hardening idler wheel, as depicted in figs. 1 and 2.The gas
Cylinder sleeve escape profiling finish rolling hardening idler wheel, including roller body 1, the roller body 1 include the arc rolling of both ends setting
Portion 2 and middle part are connected through the centre bore 3 being arranged, and between arc rolling portion 2 and centre bore 3 by cone connection 4, arc
The radius equivalent setting of the radius in rolling portion 2 and escape 5 to be processed guarantees that 5 circular arc position of escape is complete in the rolling process
Portion's stress plays the effect uniformly improved.
The hardness in arc rolling portion 2 is HRC60 ~ HRC65, and the hardness in preferred arc rolling portion 2 is
HRC62, and cylinder liner material hardness to be processed in HRC35 hereinafter, the hardness in arc rolling portion 2 is much higher than cylinder jacket matrix
Hardness, therefore, very prolonged difficult use, service life are long in use for the reinforcing idler wheel.While in order to improve the strong of roller body
It spends, in the present embodiment, arc rolling portion 2, centre bore 3 and cone connection 4 are using integrated molding setting.
When work, roller body 1 is mounted on hydraulic rolling mechanism by centre bore 3, and hydraulic rolling mechanism drives idler wheel
Ontology 1 is mobile to cylinder jacket according to given angle, after arc rolling portion 2 contacts the escape 5 of cylinder jacket, under hydraulic action,
Arc rolling portion 2 is tightly fitted on the circular arc of cylinder jacket escape 5, and main shaft of numerical control machine tool drives cylinder jacket rotation, idler wheel sheet
The idler wheel with the rotation of cylinder jacket of body 1 uniformly rolls the circumferencial direction of withdrawing groove location to realize, effectively improves withdrawing
Finish, surface hardness and the surface compact degree of slot play great improvement to escape fatigue crack-resistant ability is improved.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
