Abstract

The utility model discloses a sealed piston ring. A groove is formed on one end surface of a piston ring body, and a sealing column adapted to the groove is arranged on the other end surface of the piston ring body; the cross section of the sealing column is square, and the thickness and the width of the sealing column are two thirds of the thickness and the width of the piston ring body respectively; the size of the groove is adapted to that of the sealing column; an axial clearance and an end clearance between the groove and the sealing column are 0.25 to 0.45. By adopting the sealed piston ring, the air leakage is two thirds of that of an ordinary piston ring during operation, fuel is saved by 30 percent on average, the capacity of controlling oil is good, and the air pollution is less. Furthermore, the utility model has the advantages of energy conservation, environmental protection and durability, thoroughly overcomes a major obstacle of gas blowby and oil pumping of the ordinary piston ring from a ring opening, and can enable the service life of an engine to be prolonged by more than one time, increase the output power of the engine, and ensure that all the performances and the indexes of the engine and are greatly improved.

Description

Sealed ring

Technical field

The utility model relates to the sealed ring that a kind of automobile is used.

Background technique

As shown in Figure 1, after the conventional piston ring was installed in the air cylinder sleeve of engine, two end faces of opening had certain end-gaps, though this gap is little, can be described as a passage that opens wide fully.Under engine condition, because the wearing and tearing of piston ring and cylinder wall also can make end-gaps increase between collar extension, pressurized gas and outburst gas, will scurry into crankcase from collar extension, lubricant oil also can be scurried into the firing chamber from collar extension simultaneously, thereby engine compression ratio is reduced, and output power reduces, lubricant oil increases, reduce working life, and every index such as exhaust pollution increase reduces, and this all is because due to the piston ring side clearance increase.

Summary of the invention

Goal of the invention: the purpose of this utility model provides a kind of avoiding and scurries oil from the piston ring side clearance gas blowby, thereby improves the power and the rotating speed of motor, reduces oil consumption and exhaust pollution, the sealed ring that prolongs the working life of motor.

Technological scheme: a kind of sealed ring, have a groove on the end face of piston ring body, the other end is provided with the sealing column suitable with groove.

The cross section of sealing column is a square, for guaranteeing the intensity of gap-clearance of piston rings both sides, thickness, the width of preferred sealing column are respectively 2/3 of piston ring body thickness, width, be that cross section is rectangular sealing column, the size of groove and the size of sealing column are suitable, and the axial clearance of groove and sealing column, end clearance are 0.25～0.45; The external circular diameter of described piston ring is 80-115mm, and for guaranteeing the sealing effect of piston ring, the length of described sealing column is 3.3-5.0mm.

Beneficial effect: adopt sealed ring of the present utility model, air leakage is 2/3rds of a pot type piston ring during work, the average fuel oil 30% of saving, control machine oil ability is good, and atmospheric pollution is less, energy-saving and environmental protection, durable, it thoroughly solved the plain edition piston ring from the collar extension gas blowby, scurry oil this century-old chronic disease, it can make prolong more than one times the working life of motor, and improves engine output, and the every performance and the index of motor are improved greatly.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

As shown in Figure 2, be provided with groove 1 on an end face of sealed ring, the other end is provided with the sealing column suitable with it 2, and it is formed the joining seam shape of a protrusion by axial inner trough structure and end face platform structure.For guaranteeing the intensity of seal type piston opening structure on two sides, sealing column thickness accounts for 2/3 of piston ring body thickness, and width is 2/3 of a piston ring body width, and sealing column 2 cross sections are rectangle, and axial clearance and end clearance are controlled at about 0.25～0.45; Generally between 80-115mm, for guaranteeing sealing effect, the length of sealing column 2 is at 3.3mm-5.0mm for the piston ring excircle diameter.Under the prerequisite that guarantees the every outstanding advantage of this model utility, has enough intensity and working life like this.When piston ring was installed in cylinder and puts, the sealing column 2 of the groove 1 and the other end was fitted, and as shown in Figure 3, at end face with axially form double-layer seal preferably, and was a unlimited leakage path unlike the pot type piston ring.Therefore can reach and stop pressurized gas axially and the sealing effect of radial leakage, play energy saving, increase the effect of power, minimizing noise and carbon distribution, prolong the working life of piston ring when having saved cost.

The processing of sealed ring mainly divided for three steps carried out: promptly machined grooves, process axial inside groove, processing end face platform, also have aided processes such as chamfer angle, deburring in addition.

It all is characteristics according to sealed ring that operation is manufactured in above-mentioned a few road; carry out well-designed to its locating basis, clamping and mode of operation; reach the purpose of accurately locating and clamping fast, thereby manufacturing efficient is promoted, be convenient to size of the organization production.

The utility model provides a kind of thinking and method of sealed ring; the method and the approach of this technological scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
