Abstract
The utility model discloses a piston ring with the long service life. The piston ring is characterized by including a plurality of piston ring bodies (1) which can be combined and connected to form a ring, and a spring ring (2) sleeving the piston ring bodies (1), wherein upper and lower cuts (3) of the piston ring bodies (1) are reverse in the direction, and steps are reserved; one end of each piston ring body (1) is precisely matched with the cut (3) at the other end thereof; and all the piston ring bodies (1) are connected to form the piston ring through inserting and connecting the cuts. The piston ring with the long service life has the characteristics of extremely excellent sealing performance, no leakage, and no replacement within 0.5 million kilometers.
Description
Technical field
The utility model relates to a kind of piston ring, relates in particular to a kind of long lifetime piston ring.
Background technique
Piston ring is widely used in generally being divided into compression ring and oil ring on the piston of train, automobile, boats and ships etc., and compression ring mainly seals, and avoids the high pressure mixed gas in the cylinder to leak; Oil ring plays the wiper lubrication effect.At present, the piston ring great majority all are to be combined by a plurality of piston ring plates, and after the installation, because the elasticity of piston ring self, piston ring outer rim and cylinder wall fit tightly, and the interface between the piston ring plate fits tightly.Piston is done high-speed motion under high temperature and high pressure environment; Piston changes repeated friction between outer rim and the cylinder wall, thus the piston ring outer rim be easy to wearing and tearing, along with the increase of wear extent; The gap that piston is changed sides between edge and the cylinder wall can be increasing; Also phase mutual friction between the interface between each piston ring plate, also there are wearing and tearing in piston ring plate joint, and it is big that the gap of these joints also can become along with the increase of wear extent.When above-mentioned gap increased to a certain degree, fuel oil and air gas mixture in the cylinder will be leaked from the gap, and the phenomenon of over-emitting black exhaust takes place; Cause the waste and the befouling environment of fuel, also possibly make machine power not enough, inner pressure of air cylinder descends; Temperature raises, and fuel consumption increases.
To the problems referred to above, a lot of piston ring manufacturers improve through manufactured materials and manufacturing process to piston ring, to improve the working life of piston ring.Though these measures have certain effect,, still receive very big restriction the working life of piston ring because the linear reciprocating motion of piston and piston ring high speed under the environment of HTHP adds factors such as the interior carbon deposit of upper cylinder, chemical corrosion again.And often change the piston ring of different size, and waste time and energy, also increased the user cost and the maintenance cost of machine.
Summary of the invention
The purpose of the utility model is in order to address the above problem, a kind of long lifetime piston ring to be provided, have 5,000,000 kilometers working life, makes piston ring need not to change, good seal performance, and user cost and maintenance cost are low.
In order to achieve the above object, the technological means that adopts of the utility model is: the long lifetime piston ring is characterized in that: comprise a plurality ofly can being connected into the piston ring body of ring and being enclosed within the spring ring on the piston ring body; Said piston ring body top and bottom cut-out direction is opposite, and leaves step, and an end and the other end otch of piston ring body just in time mate, and each piston ring body connects into piston ring with the otch inserting mode.
The beneficial effect of the utility model is: piston ring body top and bottom cut-out direction is opposite, and leaves step, and an end and the other end otch of piston ring body just in time mate, ring body is pegged graft after, seamless, sealability is splendid; Each piston ring body connects into piston ring with the otch inserting mode, is enclosed within the spring ring on the piston ring body, makes piston ring have the wear-resisting effect of high level; And guaranteed to seal and do not revealed; Can reach piston and scrap and also need not to change the working life with 5,000,000 kilometers, and user cost and maintenance cost are low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation (broken section) of the utility model.
Embodiment
As shown in Figure 1; The long lifetime piston ring comprises oil ring and compression ring, it is characterized in that: comprise a plurality ofly can being connected into the piston ring body 1 of ring and being enclosed within the spring ring 2 on the piston ring body; 1 at least 2 of the piston ring body of composition piston ring is set to 3 in the present embodiment; Said piston ring body 1 top and bottom otch 3 is in the opposite direction, and leaves step, and an end of piston ring body 1 and the other end otch 3 just in time mate; Each piston ring body 1 connects into piston ring with the otch inserting mode; Because otch 3 is in the opposite direction, and leaves step, makes the piston ring packing performance splendid; Cooperate the spring ring of outside cover to make the wear-resisting property of piston ring reach 5,000,000 kilometers, all need not more rering even piston damages.
Claims (3)
1. long lifetime piston ring is characterized in that: comprise a plurality ofly can being connected into the piston ring body (1) of ring and being enclosed within the spring ring (2) on the piston ring body (1); Said piston ring body (1) top and bottom otch (3) are in the opposite direction, and leave step, and an end of piston ring body (1) and the other end otch (3) just in time mate, and each piston ring body (1) connects into piston ring with the otch inserting mode.
2. long lifetime piston ring according to claim 1 is characterized in that: described piston ring body (1) is provided with 2 at least.
3. long lifetime piston ring according to claim 1 is characterized in that: described piston ring body (1) is provided with 3.
