Technical Field

The invention relates to the technical field of automobile accessories, in particular to a piston ring with an anti-sticking layer.

Background

Piston rings (piston ring) are metal rings used to be embedded inside a piston groove and are classified into two types: a compression ring and an oil ring. The compression ring can be used for sealing the combustible mixed gas in the combustion chamber; the oil ring is used for scraping the redundant oil on the cylinder, and the invention relates to a compression ring.

The piston ring has four functions of sealing, regulating engine oil (controlling oil), conducting heat (transferring heat) and guiding (supporting). Sealing: the gas is sealed, so that gas in a combustion chamber is prevented from leaking to a crankcase, the leakage amount of the gas is controlled to be the lowest limit, and the heat efficiency is improved. Air leakage not only reduces the power of the engine, but also deteriorates the engine oil, which is the main task of the air ring; adjusting machine oil (oil control): the redundant lubricating oil on the cylinder wall is scraped, and meanwhile, a thin oil film is distributed on the cylinder wall, so that the normal lubrication of the cylinder, the piston and the ring is ensured, which is the main task of the oil ring. In modern high-speed engines, the function of a piston ring for controlling an oil film is particularly emphasized; heat conduction: the heat of the piston is conducted to the cylinder sleeve through the piston ring, namely, the cooling effect is realized.

The existing piston ring is required to bear ignition, explosion, propulsion and other operations of fuel in a combustion chamber when in use, so that the piston ring is required to have good sealing performance when in use, if the sealing performance of the piston ring is not good, the output power of an engine is reduced or the fuel consumption of the engine is increased, and the engine is damaged after a long time, so that the engine is scrapped.

Disclosure of Invention

The invention aims to provide a piston ring with an anti-sticking layer, which aims to solve the problems that the poor sealing performance of the piston ring proposed in the background art can cause the reduction of the output power of an engine or the increase of the oil consumption, and the damage of the engine can be caused after a long time, so that the engine is scrapped.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a piston ring with non-stick layer, includes the ring body, is equipped with the opening on the ring body, is equipped with first buckle respectively at the both ends of ring body, is equipped with the second buckle at the other end, and first buckle is connected with the cooperation of second buckle, is equipped with the recess in ring body one side, is equipped with first seal groove and second seal groove in recess inner wall one side, and first seal groove and second seal groove parallel arrangement all are equipped with non-stick layer in the ring body outside and inboard.

Form corresponding indent between first buckle and the second buckle, be equipped with first tooth on first buckle, be equipped with first alveolus on the second buckle, first tooth is connected with first alveolus cooperation, is equipped with second tooth on the second buckle, is equipped with the second alveolus on the first buckle, and the cooperation connection can be accomplished with the second alveolus to the second tooth.

The first convex teeth and the second convex teeth are both trapezoidal, and the first convex teeth and the second convex teeth are arranged upside down.

One end of the first sealing groove extends into the first buckle, and one end of the second sealing groove extends into the second buckle.

The inner wall of the groove is provided with a mounting groove, and a reinforcing plate is mounted in the mounting groove.

The ring body outside is equipped with two sets of sealing rings, and every group sealing ring is two relative sealing rings, is equipped with the buffer at the sealing ring inboard, and the sealing ring is the software metal material, and every group sealing ring all sets up with corresponding first seal groove and second seal groove are corresponding.

The two ends of the sealing ring are connected through connecting plates, the cross section of each connecting plate is the same as that of the corresponding buffer area, and a buffer groove is formed in one side, close to the ring body, of each connecting plate.

The invention has at least the following beneficial effects:

the piston ring is characterized in that first buckles are respectively arranged at two ends of a ring body, a second buckle is arranged at the other end of the ring body, the first buckle and the second buckle are connected in a matched mode to form a corresponding pressure groove between the first buckle and the second buckle in a matched mode, a first tooth is arranged on the first buckle, a first tooth groove is arranged on the second buckle in a matched mode, a second tooth is arranged on the second buckle, a second tooth groove is arranged on the first buckle, the second tooth and the second tooth groove can be connected in a matched mode, when the piston ring is used, the pressure groove generated by the first buckle and the second buckle in a matched mode can be influenced by fuel oil combustion explosion in a combustion chamber, due to the fact that the cross section of the pressure groove is triangular, impact force can be changed into thrust force on the first buckle and the second buckle, the first buckle and the second buckle can move towards opposite directions, and therefore the first tooth and the second tooth with the corresponding first tooth groove, the second tooth groove and the cross section of the first tooth are trapezoidal in shape, The second tooth sockets are matched more tightly, so that the sealing performance is effectively improved;

the piston ring is provided with a groove on one side of a ring body, a first sealing groove and a second sealing groove are arranged on one side of the inner wall of the groove, one end of the first sealing groove extends into a first buckle all the time, one end of the second sealing groove extends into a second buckle all the time, a mounting groove is arranged on the inner wall of the groove, and a reinforcing plate is mounted in the mounting groove;

the outer side of a ring body of the piston ring is provided with two groups of sealing rings, each group of sealing rings is two opposite sealing rings, the inner sides of the sealing rings are provided with buffer zones, the sealing rings are made of soft metal materials, each group of sealing rings is arranged corresponding to a corresponding first sealing groove and a corresponding second sealing groove, the two ends of each sealing ring are connected by a connecting plate, the cross section shape of each connecting plate is the same as that of each buffer zone, one side of each connecting plate, which is close to the ring body, is provided with a buffer groove, when in use, a groove can be influenced by fuel combustion and explosion in a combustion chamber to cause a transient groove expansion phenomenon, the groove expansion can cause the expansion of the first sealing groove and the second sealing groove, the transient expansion of the outer side of the ring body can be caused because the first sealing groove and the second sealing groove are close to the outer side, the area of buffer takes place to enlarge, causes the cooperation between sealing ring and the piston cylinder more inseparabler to obtain better leakproofness, after the burning in the piston cylinder is accomplished, because the space of buffer takes place the inflation, can cause the phenomenon of negative pressure, cause the sealing ring to get back to original position faster, when preventing next impact in the piston cylinder from arriving, the sealing ring does not get back to and treats operating condition.
