Abstract
The utility model discloses a durable environment-friendly piston ring which comprises a plurality of piston ring bodies and oil scraper rings, wherein the external diameter of each piston ring body is identical to the internal diameter of the oil scraper ring; and the piston ring body is sheathed in the oil scraper ring. The utility model has the following advantages: the oil scraper rings prevent the piston ring bodies from generating slight gas pressure leakage in the vibration process, and the oil scraper rings used as the spacing rings of the piston rings also prevent the phenomena of engine oil combustion and the like, so that the piston ring is environment-friendly; the cambered connection ring and the interface ring are inserted through a notch groove to form the piston ring body and the oil scraper ring; the insertion of the notch groove is seamless and has favorable sealing property; the oil scraper ring is arranged outside the piston ring body, so that the piston ring has abrasion resistance, ensures the sealability and no leakage, has the service life of millions of kilometers, does not need to be replaced even if the piston is discarded; and thus, the utility model has the advantages of low use cost and low maintenance cost, and is convenient for popularization.
Description
Technical field
The utility model relates to a kind of piston ring, is specially a kind of durable environment protection piston ring, belongs to mechanical field.
Background technique
Piston ring is major impetus component on the motor, it is arranged between the piston ring, under turning round working state for a long time, motor will cause the heavy wear collar extension to broaden, to cause air pressure gas leakage to reduce engine power, piston ring is subject to can causing under the high speed vibration small part air pressure to leak in the ring nest, seriously cause the burn oil phenomenon, make the motor befouling environment that behind compression and combustion, produces thick smoke.For the problems referred to above, a lot of piston ring manufacturers improve by manufactured materials and manufacturing process to piston ring, to improve the working life of piston ring.Although these measures have certain effect, because the linear reciprocating motion of piston and piston ring high speed under the environment of High Temperature High Pressure adds again the factors such as the interior carbon deposit of upper cylinder, chemical corrosion, still be very restricted the working life of piston ring.And often change the piston ring of different size, and waste time and energy, also increased user cost and the maintenance cost of machine.
The model utility content
Deficiency for the prior art existence; technical problem to be solved in the utility model is; a kind of durable environment protection piston ring is provided; solved the rear lost of life of the long-term use of piston ring; air pressure is revealed the problem of befouling environment; piston ring can be used for a long time need not to change, good seal performance, user cost and maintenance cost are low.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of durable environment protection piston ring, comprise some piston ring bodies and scraper ring, and its piston ring body diameter is identical with the scraper ring internal diameter, and the piston ring body is socketed on scraper ring inside.
Optimize, above-mentioned durable environment protection piston ring, its piston ring body comprises several arc T-Rings, and the end of arc T-Ring is provided with undercut groove, and the arc T-Ring forms the piston ring body by inserting mode.
Optimize, above-mentioned durable environment protection piston ring, its scraper ring comprises several interface rings, and the end of interface rings is provided with undercut groove, and interface rings forms scraper ring by inserting mode.
Optimize, above-mentioned durable environment protection piston ring, the quantity of its arc T-Ring is 2-3.
Optimize, above-mentioned durable environment protection piston ring, the quantity of its interface rings is 2-3.
The beneficial effects of the utility model are: the setting of scraper ring has prevented that the piston ring body from producing small part air pressure and leaking in vibrations, and scraper ring has also prevented the phenomenons such as burn oil as one cage ring of piston ring body, makes piston ring reach the environmental protection purpose; Arc T-Ring and interface rings are pegged graft by undercut groove and are formed piston ring body and scraper ring, undercut groove is pegged graft seamless, sealability is fine, scraper ring makes piston ring have the wear-resisting effect of high level in the piston ring external body, and guaranteed the sealing do not reveal, working life with millions of kilometers, can reach piston and scrap and also need not to change, user cost and maintenance cost are low, are convenient to promote.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further set forth technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the utility model is a kind of durable environment protection piston ring, comprises some piston ring bodies 1 and scraper ring 2, and its piston ring body 1 external diameter is identical with scraper ring 2 internal diameters, and piston ring body 1 is socketed on scraper ring 2 inside.Piston ring body 1 comprises several arc T-Rings 3, and the end of arc T-Ring 3 is provided with undercut groove 31, and arc T-Ring 3 forms piston ring body 1 by inserting mode.Scraper ring 2 comprises several interface rings 4, and the end of interface rings 4 is provided with undercut groove 41, and interface rings 4 forms scraper ring 2 by inserting mode.The quantity of arc T-Ring 3 is 2-3.The quantity of interface rings 4 is 2-3.
The beneficial effects of the utility model are: the setting of scraper ring has prevented that the piston ring body from producing small part air pressure and leaking in vibrations, and scraper ring has also prevented the phenomenons such as burn oil as one cage ring of piston ring body, makes piston ring reach the environmental protection purpose; Arc T-Ring and interface rings are pegged graft by undercut groove and are formed piston ring body and scraper ring, undercut groove is pegged graft seamless, sealability is fine, scraper ring makes piston ring have the wear-resisting effect of high level in the piston ring external body, and guaranteed the sealing do not reveal, working life with millions of kilometers, can reach piston and scrap and also need not to change, user cost and maintenance cost are low, are convenient to promote.
More than show and described basic principle of the present utility model and major character and advantage thereof.The technology personage of the industry should understand; the utility model is not subjected to the restriction of above-mentioned implementing regulations; what describe in above-mentioned implementing regulations and the specification is to be used for illustrating principle of the present utility model; under the prerequisite that does not break away from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong in claimed the utility model scope.
The claimed scope of the utility model defines with appending claims and other equivalent.
