Abstract
The present invention relates to a novel piston ring--a single groove piston ring for a reciprocating type piston engine, which has a quadrangular cross section and is formed by overlapping two circular rings with trapezoidal cross sections. The single groove piston ring which can replace a plurality of piston rings of the existing engine has the advantages of simple structure, simple technology, enhancement of the sealing properties of the piston ring and a cylinder, enhancement of the power and the rotation number of an engine, obvious economic characteristics, reduction of the engine volume and extension of the service life of an engine. The single groove piston can be used for internal combustion engines, gasoline engines, diesel engines, air compressors, vacuum engines, steam engines and other mechanical devices with piston assemblies.
Description
The present invention is a kind of single groove piston ring, belongs to the improvement of Reciprocating engine piston ring, replaces Reciprocating engine multiple-grooved piston ring by single groove piston ring.
Motor vapour ring and oil ring are used for gap between packed-piston and the cylinder.As everyone knows, in order to improve the casing wall sealing, petrol engine is equipped with 2-4 road compression ring, diesel engine is equipped with 2-6 road compression ring, because compression ring increases and causes frictional force to increase, and causes the wearing and tearing of piston ring and cylinder liner thereupon, lubricated uneven, noise greatly, reduced the power of motor.
Purpose of the present invention: the single groove piston ring that provides the high leak tightness of a kind of power of reducing friction and pump atmidometer.When working stroke, except the elastic force of material own, also will increase the tension force of piston ring by the component of cylinder pressure, improve the sealability of casing wall; When the subsidy stroke, piston ring is not by the component of cylinder pressure, and the resistance of reducing friction reduces the pump atmidometer to the greatest extent.
Invention is to realize like this.Power equipments such as current various petrol engine, diesel engine, air compressor, vacuum machine, steam engine, the piston ring section configuration that is adopted mostly is trapezoidal, square or rectangular, and several piston rings are placed respectively in the piston ring groove, complex structure is difficult to overcome the gas leakage of ring back clearance.And single groove piston ring is to be that trapezoidal ring and the section configuration of going up is that the following ring stack combinations of trapezoidal marginal zone groove is integral by a section configuration.Can replace existing multiple-grooved piston ring with single groove piston ring, simple in structure, tension force is big, can improve sealability, the resistance of reducing friction, reduce the pump atmidometer, thereby improved the power character and the Economy of motor.
The present invention is to be that trapezoidal ring and the section configuration of going up is that the following ring of trapezoidal marginal zone groove is superimposed to form single groove piston ring by a section configuration, and has the function of compression ring and oil ring concurrently.No matter being that petrol engine, diesel engine, air compressor, vacuum machine, steam engine etc. are all has the machinery of piston assembly mechanism all can adopt.This novel piston ring can contact former piston ring with the face of cylinder, change the line contact into.The resistance of reducing friction, improve sealing, prevent that machine oil is splashed into the firing chamber, make the oil film of casing wall float evenly lubricated, reduce the swing of piston ring and to the piston groove impact shock of both sides up and down, guarantee that mixed gas fully burns, make motor reach low specific fuel consumption, low noise, low * degree, low pollution, reduce the motor volume, improve power, prolong the motor purpose in working life.The present invention is the once new technological revolutions of various motors.The present invention has an embodiment: AC Jiefang brand motor car engine was through 4 years platform experiments, and per minute 2800 is 113 horsepowers when changeing, and per minute 1800 is minimum fuel consumption 215 grams when changeing, 35.2 kilograms of Maximum Torques. meter.The present invention need only be changed existing piston ring or be redesigned piston by requirement of the present invention, can use single groove piston ring.
The concrete structure of invention is by description of drawings.
Fig. 1 is the single groove piston ring assembling schematic representation after the available engine repacking that proposes according to inventing mutually.
Fig. 2 is the piston schematic representation that proposes according to the present invention.
Fig. 3 encircles schematic representation on the single groove piston ring.
Fig. 4 is a ring schematic representation under the single groove piston ring.
Single groove piston ring is that two diameters are conformed to, and section configuration is that ring [4] and section configuration are trapezoidal overlapping being combined into one of following ring [5] on the trapezoidal piston ring, and is placed in the piston ring groove [3], with piston body [2] and the piston assembly of wrist pin [7] composition.Ring [4] and encircle down [5] locating stud and opening [9], opening [9] gap are all arranged is the 0.3-0.45 millimeter on the piston ring, locating stud makes the opening of upper and lower ring not on a position, guaranteed the sealability of piston ring, the disadvantage that has overcome former gap-clearance of piston rings and leaked gas by the crack.Piston body [2] is provided with oil groove [6], is provided with piston pin clamping spring [8] on wrist pin [7], and piston assembly is placed in the cylinder liner [1].Fig. 2 has disclosed single groove piston ring groove [3] physical dimension.Last ring [4] section is trapezoidal, and its outer rim is level and smooth figure curved surface.Following ring [5] section also is trapezoidal, its outer rim has the material that encircles [4] and following ring [5] on Baltimore groove [10] single groove piston ring all can adopt gray cast iron, spheroidal graphite cast iron, powder metallurgy, ceramet, malleable cast iron or alloy cast iron (adding alloying elements such as a little copper, chromium, molybdenum in the high-quality gray cast iron), through fusing, the casting of injection corresponding model is through the machining moulding.Inclined-plane [11], both sides and the outer rim of last ring [4] and following ring [5] can adopt form copying, heat setting method or the machine shaping of employing special tool, also will be through correct grinding, degree of finish is not less than 8, curvature is not more than the 0.003-0.004 millimeter, following ring [5] is still needed through heat treatment, chromium plating, can improve wear-resisting, heat resistance, the groove of its outer rim [10] is for preventing that lubricant oil from oozing out and store lubricant oil, to guarantee what piston [2] was provided with the lubricated and sealing of cylinder [1], play the double action of compression ring, oil ring, and need not set up compression ring and oil ring.Single groove piston ring can improve piston ring sealing, running-in ability, scrape oiliness and anti-wound property.
