Abstract
The utility model provides a novel piston ring, includes the ring body, ring body one end is equipped with opening, its characterized in that: the inner wall of ring body is equipped with an at least fluting. Be equipped with the fluting through the inner wall at the ring body, the intensity and the tension of piston ring obtain improving, make piston ring difficult rupture and warping when demolising or install, and have alleviateed the weight of piston ring, are favorable to improving power machinery's speed, and simultaneously, grooved setting has increased the area of inner wall, is favorable to the heat dissipation.
Description
Technical field
The utility model relates to a kind of component of dynamic power machine, particularly relates to a kind of novel piston ring.
Background technique
Piston ring is arranged on the piston of dynamic power machine, is divided into compression ring and oil ring, and compression ring, for ensureing a sealing of piston and cylinder wall, improves power; Oil ring is for striking off gasoline unnecessary on cylinder wall, reduces oil consumption, prevents carbon deposit.
In routine duties, want often to carry out some maintenance and repair work to dynamic power machine, frequent needs are removed or ring installation, because some trickle deformation occur piston ring at work, the intensity of piston ring and tension force can decline to some extent, very easily fractureed in dismounting or installation process or be out of shape, can not reuse, piston ring is caused to be scrapped, waste material, even new piston ring, when installing for the first time, also easily fractureed because of undue force or be out of shape, therefore piston ring frangibility and yielding problems demand in dismounting or installation process solves.
Model utility content
The utility model, in order to solve the problems of the technologies described above, provides a kind of intensity good, the novel piston ring of not frangibility and distortion.
The technological scheme that the utility model adopts is, provides a kind of novel piston ring, comprises ring body, and described ring body one end is provided with opening, and the inwall of described ring body is provided with at least one fluting.
Further, described fluting is located at the middle part of the inwall of described ring body.
Further, the width of described fluting is 0.1-0.25mm.
Further, the degree of depth of described fluting is 0.1-1.0mm.
Further, the distance of 2-30mm is left between the opening end of described fluting and described ring body.
Further, described novel piston ring is compression ring.
The beneficial effects of the utility model are, at the inwall of ring body, fluting is set, according to mechanics principle, intensity and the tension force of piston ring are improved, and make piston ring not frangibility or distortion when removing or install, and alleviate the weight of piston ring, be conducive to the speed improving dynamic power machine, meanwhile, the setting of fluting, increase the area of inwall, be conducive to heat radiation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, 1-ring body, 2-fluting.
Embodiment
Below in conjunction with accompanying drawing 1, enforcement of the present utility model is described in further detail.
A kind of novel piston ring, comprise ring body 1, described ring body 1 one end is provided with opening, the inwall of described ring body 1 is provided with a fluting 2, described fluting 2 is located in the middle part of inwall, the width of described fluting 2 is preferably 0.1mm, the degree of depth is preferably 0.5mm, the hierarchy structure of described fluting 2 is determined by the concrete size of described ring body 1, the hierarchy structure of described fluting 2 is less than width and the thickness of described ring body 1, described fluting 2 can not run through described ring body 1, otherwise not only can not strengthen tension force and intensity, also can badly influence the sealing of piston ring, simultaneously, the degree of depth of described fluting 2 can not be greater than 3/4ths of described ring body 1 thickness, because piston ring operationally can rub with casing wall, piston ring weares and teares unavoidably, if the degree of depth of described fluting 2 is excessive, cause the bottom land of described fluting 2 excessively thin, easily be worn through, affect the sealing of piston ring.Distance between described fluting 2 and the opening end of described ring body 1 is preferably 10mm, because described fluting 2 extends to opening end or too close to opening end, gas can be entered in described fluting 2 by opening end, has influence on the sealing of described novel piston ring.
Described novel piston ring is used as compression ring, for the burning mixture in the firing chamber of sealed motive force machinery or liquid, relies on the pressure difference of gas or liquid, at ring periphery and cylinder and form sealing between ring and a side of annular groove.
The piston of dynamic power machine is provided with annular groove, and described novel piston ring struts and is enclosed within annular groove by general manpower or instrument, and described novel piston is equipped with described fluting 2.Illustrate from amechanical angle, the material of same component, cause the pillar of hollow, than solid pillar, its tension force and intensity all will be got well, the utility model utilizes this principle, the inwall of described ring body 1 arranges described fluting 2, and tension force and the intensity of described novel piston ring are improved, and make described novel piston ring not easily be fractureed when removing or install or be out of shape, and the setting of described fluting 2, alleviate the weight of piston ring, be conducive to the speed improving dynamic power machine, simultaneously, increase the area of inwall, be conducive to heat radiation.
In sum, the utility model, as specification and diagramatic content, makes actual sample and through repeatedly use test, from the effect of use test, provable the utility model can reach its desired object, and practical value is unquestionable.Above illustrated embodiment is only used for conveniently illustrating the utility model, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristics, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristics content of the present invention, all still belong in the scope of the utility model technical characteristics.
