Abstract
The utility model discloses a strengthening oil ring of a combustion engine. The strengthening oil ring comprises a coil loaded spring and a ring-shaped basal body with an oil return hole, wherein the outer circular surface of the ring-shaped basal body is provided with an upper oil scraping edge and a lower oil scraping edge, the inner circular surface of the ring-shaped basal body is provided with a loaded spring groove, the shape of the cross section of the loaded spring is of semicircular arc, the coil loaded spring is arranged in the loaded spring groove, the outer circular surface in or near a half circular arc on the coil loaded spring is contacted with the wall of the loaded spring groove, the whole inner circular surface of the ring-shaped basal body is provided with a hard chrome coating. The strengthening oil ring has the characteristics of excellent wear resistance performance, long service life, large rigidity, small deformation and reasonable structure, and is especially suitable for the high requirements to the performance and service life of the oil ring in combustion engine vehicles with high-speed overloading and low emission.
Description
Technical field
The utility model relates to a kind of piston ring of internal-combustion engine, especially a kind of oil ring with helical supporting spring.
Background technique
Internal-combustion engine is when work, in order to satisfy the rational lubricant film of compression ring outer round surface, prevent that the dry friction phenomenon of piston ring and inboard wall of cylinder liner from taking place, lubricant oil unnecessary on the inboard wall of cylinder liner to be scraped simultaneously, prevent that machine oil from scurrying into the firing chamber, oil ring need be installed on piston.Traditional oil ring is the helical supporting spring oil ring, and support spring provides elastic force to make oil ring and inboard wall of cylinder liner keep excellent contact.In the oil ring working procedure, there are sliding friction in support spring and oil ring support spring groove inner headed face, and the oil ring material is common alloy cast iron, and the support spring material is a carbon spring steel, thereby have caused the fretting wear of oil ring inner headed face, with the wear extent maximum of interior round bottom portion.Because interior round bottom portion is the thinnest, but also several spill ports are circumferentially arranged, the wearing and tearing of interior round bottom portion will seriously weaken the design strength of oil ring, even cause oil ring to rupture, and shorten the working life of oil ring.
For strengthening the working life of oil ring, Chinese patent 200820033116.5 discloses a kind of spiral lining spring oil ring, this M shape oil ring ring back adopts chromium plating to strengthen, yet this M shape oil ring becomes local line to contact with the lining spring, in the using process, oil ring all can produce small vary in diameter in each cycle of motion, the pitch that is reflected in the lining spring changes, the friction of lining spring and oil ring promptly takes place, the line contact can increase the fretting wear of the oil ring ring back of the body and lining spring, when the chromium coating wearing and tearing are big, can cause oil ring intensity sharply to descend, will cause taking place the stuck or abscission ring accident of lining spring under the serious situation.On the other hand, this M shape oil ring easy moderate finite deformation that produces when bearing heavy load causes this oil ring to lose efficacy the needs of incompatibility heavy duty.
Summary of the invention
The reinforcement oil ring that provides a kind of wear resistance good, rational in infrastructure is provided the purpose of this utility model.
In order to achieve the above object, the technical solution of the utility model is: a kind of reinforcement oil ring, comprise helical supporting spring and the ring-type matrix that has spill port, the periphery of ring-type matrix has last frizing sword and following frizing sword, the inner headed face of ring-type matrix has the support spring groove, the sectional shape of support spring groove is to be the semicircular arc groove, the helical supporting spring support spring groove of packing into, make the semi-circle on the helical supporting spring or contact with the cell wall of support spring groove near the periphery of a semi-circle, the whole inner headed face of ring-type matrix has hard chromium.
Described hard chromium thickness is 0.01～0.10mm.
The last frizing sword of described ring-type matrix and following frizing cutlery have hard chromium.
The last frizing sword of described ring-type matrix and following frizing sword are two-way chamfering or unidirectional chamfering.
Described helical supporting spring surface has resin layer.
After adopting said structure, because the sectional shape of support spring groove is to be the semicircular arc groove, the helical supporting spring support spring groove of packing into, make the semi-circle on the helical supporting spring or contact with the cell wall of support spring groove near the periphery of a semi-circle, evenly stressed, the friction of the semicircle cell wall of support spring groove, avoided the concentrated wear phenomenon effectively, so wear resistance is good; Again because the whole inner headed face of ring-type matrix has hard chromium, make this coefficient of sliding friction of helical supporting spring and hard chromium reduce about half than prior art to friction pair, be about 0.1, and hard chromium hardness height, the antiwear property of oil ring is significantly improved, guaranteed oil ring intensity effectively, thereby improved the usability of oil ring, prolonged working life, to the positive effect of overall performance generation of motor.In addition, it is big that the utility model also has rigidity, is out of shape for a short time, and characteristic of reasonable structure especially satisfies the high request that internal combustion locomotive high-speed overload and low emission proposed piston ring performance and working life, good market prospects.
