Abstract
The utility model discloses a reinforced overlapping and sealing piston ring. The piston ring comprises a ring body, wherein an overlapping notch is arranged on the ring body; the overlapping notch takes the step shape and is provided with two or more than two steps; the corner of the step is 90-180 degrees; and a layer of ceramic film is arranged on the surface of the ring body and on the surface of the overlapping notch respectively. As the piston ring serves as one of the crucial parts of an internal-combustion engine, the sealing property of an air cylinder is better, more oil is saved, and the working efficiency of the internal-combustion engine is improved.
Description
Technical field:
The utility model relates to a kind of internal-combustion engine piston ring, particularly a kind of reinforced lap seal piston ring.
Background technique:
Piston ring is one of key components and parts in the internal-combustion engine, and the quality of its sealability directly influences the work operation of internal-combustion engine.Sealability is low, and cylinder easily produces collaborates, goes here and there oily phenomenon, and fuel oil can not fully be burnt, oil consumption, and working efficiency of internal combustion engine is low, and job costs are higher.In order to improve the sealability of piston ring, adopting the overlapping sealing at the jointing of piston ring is a kind of technological scheme preferably.
The model utility content:
The purpose of this utility model: design a kind of reinforced lap seal piston ring, improved sealability, help improving working efficiency of internal combustion engine, save fuel oil, this reinforced lap seal piston ring has adopted the overlapping structure, the cylinder phenomenon of collaborating is controlled to bottom line, fuel oil is fully burned, makes internal-combustion engine in whole using process, be in high-seal, keep cylinder to press the steady-working state that does not descend.The utility model has increased wear-resisting property later on being provided with layer of ceramic film.
The technical solution of the utility model is as follows:
This reinforced lap seal piston ring comprises ring body 1, and ring body 1 is provided with overlapping breach 2, and overlapping breach 2 is ladder-type and is provided with two or more steps.
The turning of described step is the 90-180 degree.
The turning of described step is 90 degree.
Described overlapping breach 2 surfaces are provided with layer of ceramic film 3.
Described ring body 1 surface also is provided with layer of ceramic film 3.
The beneficial effects of the utility model are:
1, sealability and cylinder pressure have been improved.
2, combustion engine powered powerful lastingly, good dynamic property, carrying capacity is big, and climbing power is strong, has improved efficient.
3, save fuel oil, can directly reduce job costs.
4, toxic emission is low, is beneficial to environmental protection.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2, reinforced lap seal piston ring of the present utility model, comprise ring body 1, ring body 1 is provided with overlapping breach 2, overlapping breach 2 is ladder-type and is provided with two steps, overlapping breach 2 can be sealed and matched, and described step turning is 135 degree, and overlapping breach 2 surfaces are provided with layer of ceramic film 3; Described ring body 1 surface also is provided with layer of ceramic film 3.
Adopted of the present utility model combustion engine powered powerful lastingly, good dynamic property, carrying capacity is big, climbing power is strong, has improved efficient.Save fuel oil, reduced job costs.
The turning of described step can also be chosen in 90-180 degree scope, and corner angle comprises 90 degree, does not comprise 180 degree.
