Abstract

The utility model discloses a self-expanding piston ring, which relates to perishable parts of the explosive motor. The self-expanding piston ring employs the following technical schemes: three cellular objects (1), three cellular objects (2), cellular objects made one to one, which is characterized in that, the oblique plane of three cellular objects (1) holds the oblique plane of the three cellular objects (2), a spring (3) cooperates with the style of the ring automatically, the abrasion of the automatic expansion ring enlarges with the abrasion of the cylinder coordinately. The ring overcomes three persistent ailments of the traditional ring (edge grinding early, air escape and misuse of machine oil). The oblique plane of the three cellular objects (2) is installed in the piston groove, thereby the three cellular objects (2) can lengthen the usage of abrasion. The self-expanding piston ring seals well, saves oil a lot and increase the service life, thereby making the well-known perishables parts of the engine in the long run.

Description

Automatic expanding piston ring

Technical field

The flexible automatically piston ring that expands of the utility model relates to explosive motor accessory, easily damaged parts.

Background technique

Generally acknowledged at present motor, piston ring, many insoluble problems appear in long-time running, and easily damaged parts is constantly changed, and waste of manpower, holding time are trusted subordinate's hidden danger of explosive motor industry, and the utility model automatic expanding piston ring replaces the tradition ring.

Summary of the invention

Normally use for overcoming motor, solve the easily damaged parts that the tradition ring is generally acknowledged, the utility model provides a kind of automatic expanding piston ring.

The utility model automatic expanding piston ring adopts scheme, 1 three of ring-like bodies, 2 three of ring-like bodies, 1 joins 1 is built into ring garden body, its feature, 2 three of ring-like bodies, trapezoidal inclined-plane, holding in the palm 1 three of ring-like bodies, inclined-plane, type spring 3 are from movingly, and this encircles mode automatic expanding, the ring wearing and tearing, the cylinder barrel wearing and tearing are together augmented in right amount.As a kind of preferred structure of the utility model, many mouthfuls of many bodies, 2 three of ring-like bodies, trapezoidal inclined-plane, in the piston groove of packing into, these ring-like body 2 ring bodies, the wearing and tearing use amount that can extend, can select in 500,000 kilometers to 5,000,000 kilometers needs design with mileage.As a kind of preferred structure of the utility model, 2 three of ring-like bodies, ring center drill type spring 3 connecting rod holes, connect together, one connects ring-like body 2 ring center holes, and one connects piston groove inner spring hole, thereby stablize in the automatic expanding ring motion not shift(ing) ring position, stable type spring 3 autoamtic boostings.As the above-mentioned structure of selecting for use, automatic expanding piston ring, many mouthfuls of many bodies, Structural Hardware, ring-like body 1, ring-like body 2, trapezoidal ramp structure, type spring 3 cooperate, the needs that ring wearing and tearing, cylinder barrel wearing and tearing are augmented, solve the difficult problem that traditional collar extension is ground bigger and bigger, and should encircle not gas blowby of this sealing structure effect, increase power, strengthen environmental protection, increase the service life.

Description of drawings

Accompanying drawing is automatic expanding plug ring, plane structure chart.

Among the figure: 1 ring-like body, 2 ring-like bodies, 3 type springs.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

In the accompanying drawing, 1 three of ring-like bodies, 2 three of ring-like bodies, 1 joins 1 is built into automatic expanding ring garden ring body, and type spring 3 autoamtic boostings cooperate in the piston groove of packing into, its vapour ring twice are building ring, one oil ring uses, and type spring 3 circular hole fixing spring connecting rods are bored in ring-like body 2 big end central positions, in the one end piston groove, 3: 120 ° of piston Ratio of the circumference of a circle to its diameter, and brill spring connecting rod hole (position, spring eye connecting rod hole, spring eye is big, the connecting rod hole is little dark), by specification, this mode is stable, mobile position not in the ring motion, guarantee that ring is indeformable, normal automatic expanding.Ring-like body 2, many bodies, trapezoidal inclined-plane increases wear extent at position of big end, and mileage design on demand increases ring-like body 2 width, quantity, and also will reach final requirement according to the material wear ability design and use, and selects in general 50 kilometers to 5,000,000 kilometers.

Claims

1. automatic expanding piston ring, it is characterized in that, (1) three of ring-like body, (2) three of ring-like bodies, 1 joins 1 is built into circular body, (2) three trapezoidal inclined-planes of ring-like body, holding in the palm (1) three inclined-plane of ring-like body, type spring (3) is from movingly, and this ring mode automatic expanding encircles the wearing and tearing of wearing and tearing cylinder barrel and together augments in right amount.

2. automatic expanding piston ring according to claim 1 is characterized in that, (2) three centre-drilling holes of ring-like body, and type spring (3) connecting rod is connected with the piston groove endoporus.
