Description
Technical field
The present invention relates to a kind of sealed lubricative gaseous ring compound gasket of piston-type internal-combustion engine, belong to gas engine part.
Background technique
A few days ago internal-combustion engine aspect land and water transportation all in extensive use, existing internal-combustion engine comprises petrol engine and diesel engine, no matter be that petrol engine or diesel engine all are by at cylinder body internal combustion fuel oil, make the piston motion in the cylinder body send power to crankcase through connecting rod, because the lubricant oil deficiency that the traditional compression ring of piston transmits by oil ring, especially poorer near the top compression ring lubrication effect of firing chamber, so it is fast that the friction that causes compression ring and cylinder body to produce severe causes cylinder body to lose circle, the compression ring quick abrasion, and the influence that causes owing to the severe friction of traditional compression ring mainly contains two aspects: and the bad piston that causes of the surface of contact clearance seal performance between (1) traditional compression ring and the cylinder body has reduced output power when work done; (2), thereby, the gas that pours in down a chimney make bearing, gear, camshaft in the crankcase damage of metalwork mechanical interaction occur because having metal granule because poor sealing makes the gas of a large amount of not safe combustions machine oil in the crankcase that poured in down a chimney in the crankcase severe contamination when the piston work done.In addition because the shortcoming of following two aspects has also appearred too greatly in the gap of the junction point of traditional compression ring.
1, because the gap of junction point makes fuel oil there be not also that safe combustion is intact just to have discharged too greatly, cause discharge amount of exhaust gas to strengthen.
2, because the gap of junction point when making the piston work done too greatly, especially when heavy load climbing and acceleration suddenly, seem and be short of power, and the lubricated difficulty of traditional compression ring, poor sealing performance, not only influenced the performance of internal-combustion engine, and cause load to increase and bring high oil consumption, under the situation that the energy scarcity oil price rises steadily, solve the energy-saving and cost-reducing technical problem of motor, not only help vast motor owner and reduce user cost, and also be that a kind of support is echoed environmental protection, energy-conservation call that current country proposes.
Open source literature has been reported some improvement to the conventional piston compression ring, Chinese patent for example, the Fu Wenfei of gold Tian Town, Guiping City, Guangxi Zhuang Autonomous Region Mo Long village 15 teams; The patent of wife's parents' home's rising sun application " the thin pad of piston ring packing ", application number: 03235245.X, the thin pad of this piston ring packing, comprise by cylinder, piston, piston ring, sealed thin pad, feature is that sealed thin pad two ends have the movable identical overlap joint mouth of interior chamfering arc, the top and bottom of piston ring are equipped with the sealed thin pad respectively, and the interface of sealed thin pad is relative with the opening of piston ring to be installed greater than 90 ° of angles.Advantage is compact structure, good seal performance, increases the service life.The Xu Fuman of Jiu Bao district, Anshan, Liaoning Province agricultural machinery school has applied for the patent of " combined type gapless piston ring ", application number: 89210639.5 these compound piston rings, by interior ring, trapezoid-shaped openings ring and loop seal pad three parts are formed.Adopt this compression ring, can prevent the gas leakage of cylinder of internal-combustion engine compression ring effectively, mechanical efficiency is improved, reduce rate of fuel consumption, the useful horsepower output of increasing combustion engine.This combined gas ring is particularly suitable for some through long-time running, and cylinder and wearing for piston are more serious, and the internal-combustion engine that causes the cylinder leakage tester amount to increase uses, and can improve partial properties, increases the service life.The Xie Fengli in Zhao Zhaizixiang Xie Zhuan village, Gaotang County, Shandong Province has applied for the patent of " piston ring of band elastic washer ", application number: 97233243.X, this piston ring is a kind of piston ring with elastic washer, it is characterized in that piston ring and elastic washer be superimposed and pack in the groove of piston, and change the periphery disc of piston ring into inside concave panel, change the vertical opening of piston ring into ring radial handing-over structure.It has simple for production, practical advantage and improves the working life of piston ring and piston, the positive role that strengthens power performance, saves fuel oil and lubricant oil, is worth of widely use.The Wang Yongkai of Dashiqiao City senior middle school has applied for the patent of " combined sealed piston ring " in cultivating people of ability the Dashiqiao City in Liaoning Province, application number: 01113844.0, and this combined sealed piston ring is used for vapour, diesel engine and air compressor.Combined sealed piston ring is formed by stacking by two monocycles, and following ring has the frizing acute angle.The collar extension of monocycle is an overlap joint type.The overlap joint type collar extension that is contained in the stack piston ring in the annular groove will keep 90 °～180 °.1～2 road ring is installed on each piston to get final product.Its advantage is good seal performance, high working efficiency, long service life.
The shortcoming that the thin pad of the piston ring of above-mentioned open source literature or piston ring packing exists is the interior chamfering that is provided with that has, or intersection is installed, the easy scored cylinder of this structure, 1～2 road ring is installed on the piston that has, because two piston ring thickness are identical, be to install side by side, also may cause the situation of piston scored cylinder.
Summary of the invention
The Combined gaseous ring pad that the purpose of this invention is to provide a kind of engine piston seal lubrication, it is big to traditional compression ring lack of lubrication and traditional compression ring junction gap to solve existing internal-combustion engine solid oil ring in piston work done process, thereby make traditional compression ring big to the cylinder body wearing and tearing, lose circle easily, and poor sealing performance, caused the problem of the damage between the metalwork mechanical interaction in the crankcase.
Patent of the present invention is achieved through the following technical solutions:
Engine piston seal lubrication Combined gaseous ring pad, it is characterized in that described compression ring compound gasket structure in the form of sheets, external diameter is identical with the interior external diameter of former piston gas ring in it, install and be close to the one or both sides of former piston gas ring, thickness is thinner than former piston gas ring, the joint mouth of compression ring compound gasket and former piston gas ring interlace (the joint mouth that is pad and compression ring can not be in same position, in order to avoid the gas of cylinder is from engaging a mouthful gas leakage).
External diameter is identical with the interior external diameter of former piston ring in the compression ring pad recited above, thickness is thinner than former piston ring, for less piston ring (for example Cylinder of motorcycle piston ring), because the thickness of piston ring is about the 2-3 millimeter, we design the compression ring spacer thickness less than the 1-2 millimeter so, for medium piston ring (for example automobile cylinder piston ring), because the thickness of piston ring is about the 3-5 millimeter, we design the compression ring spacer thickness less than 2 millimeters so, for steamer, the thickness of piston ring may be reached for 10 millimeters, so we design the compression ring spacer thickness can not be too thick, should that is to say less than 4 millimeters, compression ring pad of the present invention will guarantee certain elasticity, so as not to cylinder at running by the scratch of compression ring pad.
Above-described compression ring compound gasket can be one, be installed in the back of piston ring, promptly on one side near oil ring, each one of front and back also can be installed, can press close to piston ring as long as guarantee the compression ring pad, the gap that just can prevent piston ring long slightly back wearing and tearing service time junction point is too big and produce the phenomenon of gas leakage.
The above-described compression that is arranged on the piston is suitably widened than common compression, enables to install simultaneously piston gas ring and compression ring compound gasket.Be noted that: the compression that is arranged on the piston is suitably widened than common compression, is exactly to make that the later gap of installation Combined gaseous ring pad is enough.
The following several respects of the effect of Combined gaseous ring pad.
1, the Combined gaseous ring pad can be carried under one's arms in the lubricated gap of ensconcing between Combined gaseous ring pad and the traditional compression ring when the piston exhaust, oil during to the piston work done between plant Combined gaseous ring pad and traditional compression ring crack can splash compression ring and the severe wearing and tearing of traditional compression ring to the cylinder body inboard are reduced from face in the inboard position that needs to lubricate of cylinder body, thereby also make simultaneously piston make sealing with regard to reinforcement greatly when work done admittedly for greasy property is good, pressure strengthens output power thereupon and also and then improves oil consumption and also just decrease with regard to corresponding.
So having that 2, the joint mouth of traditional compression ring is opened because the joint mouth of compression ring pad is installed in opposite direction with the joint mouth of traditional compression ring is much, the pad of Combined gaseous ring all can engage mouth to traditional compression ring all the time and block the sealing that just can strengthen compression ring and cylinder body so greatly and reduction waste gas and pour in down a chimney pollution to bent axle, and because the raising of sealability also makes the corresponding raising of combustion utilization efficiency, oil consumption also effectively reduces the corresponding wearing and tearing of metalwork in the crankcase also with regard to corresponding decline.
3, increase the Combined gaseous ring pad, simple in structure, repacking can not influence the performance of motor easily, can realize that piston is to remain best condition lubricated and sealing in work done, thereby help improving and the performance of stable motor effectively reduces the wearing and tearing of oil consumption and cylinder body and compression ring.
4, after internal-combustion engine used the Combined gaseous ring pad, oil consumption descended about 10% relatively, and operating noise descends, and the power of internal-combustion engine is not fully exerted, and has also prolonged working life, has reduced discharge of harmful gases.Patent of the present invention is applicable to various internal-combustion piston engines, both helped improving the performance of internal-combustion engine, prolong the working life of internal-combustion engine, help again cutting down the consumption of energy, reduce environmental pollution but also reduce the wearing and tearing of internal-combustion engine greatly because of piston, compression ring and cylinder body inboard, and the crankcase oil pollution has very remarkable economic efficiency and social benefit to the number of times of the required maintenance of the damage of internal-combustion engine.
