Abstract

The utility model relates to a mutual-positioning sealing ring. The utility model is characterized in that the sealing ring is composed of at least two ring slices which are mutually superposed and buckled. The scheme provided by the utility model solves the problem which is not solved in the industry of internal combustion engines design in many years. Namely, under the condition of reducing ring grooves, the utility model can achieve the purposes of improving sealing performance, saving power consumption and improving power factor.

Description

A kind of mutual location seal ring

The utility model relates to a kind of axis hole class seal element, particularly relates to a kind of mutual location seal ring that is applied to the internal-combustion engine industry.

At present, in the disappear sealing of living device (smoke-ejecting pipe) joint of internal-combustion engine vent-pipe and vehicle, the sealing between the air compression crankshaft bore, and the sealing sealing configuration forms that adopt every groove one ring between piston and cylinder sleeve in the internal-combustion engine more.With the internal-combustion engine is example, in order to guarantee the tightness between piston and the cylinder sleeve, adopt in the method for offering twice on the piston or the annular groove of seal ring being installed more than the twice solved sealing problem more, when assembling, except that the end-gaps that reduces seal ring as far as possible, the end-gaps between the piston ring in each annular groove is misplaced mutually.But in actual use; because the working environment of seal ring is to be under the mal-condition of high temperature, high pressure all the time; although being applied under the existing technical conditions, the employing of above-mentioned measure still can not satisfy its seal request well; after certain time limit of work, regular meeting has the phenomenon that power descends, energy consumption rises to take place.

The purpose of this utility model provides the scientific and rational more mutual location of a kind of structure seal ring (promptly being combined by two ring plates at least) with regard to being to overcome above-mentioned deficiency of the prior art, be implemented under the condition of annular groove minimizing, reach the raising sealability, energy efficient, the purpose of raising power factor.

The purpose of this utility model can adopt following measure to realize:

Mutual location of the present utility model seal ring is made up of at least two mutual stacked and ring plates mutual fastening.

The utility model also can adopt following measure to realize: described seal ring is mutual stacked and combine with the mutual manner of set boss on corresponding another ring plate of a ring plate opening by two; The opening part section of described two ring plates, except that its inner ring surface, its excess-three face all extends to the section part of opening with the structural type of arc-shaped transition, and forms an arc transiting surface at its section.

The utility model yet can adopt following scheme to realize: described seal ring is made up of three mutual stacked ring plates; Respectively be provided with on the upper and lower surface of ring plate in the middle of it one with two ring plates that match up and down on the positioning boss that matches of A/F.

The proposition of the utility model scheme has realized that the internal combustion (IC) Engine Design industry wants to solve a problem always for many years, promptly under the condition that annular groove reduces, reaches the raising sealability, energy efficient, the purpose of raising power factor.

The drawing of accompanying drawing is described as follows:

The plan view of the mutual location seal ring that Fig. 1 is made up of two ring plates.

Fig. 2 is that the A of Fig. 1 is to view.

The plan view of two ring plates up and down in the mutual location seal ring that Fig. 3 is made up of three ring plates.

The plan view of the middle ring plate in the mutual location seal ring that Fig. 4 is made up of three ring plates.

Fig. 5 is that the B of Fig. 4 is to view.

The utility model is done with detailed description below with reference to embodiment's (accompanying drawing), but does not limit the utility model.

As shown in Figure 1, 2, the seal ring shown in the figure is made up of two mutual stacked ring plates 1,2, and described two ring plates combine with the mutual manner of set boss 4 on a ring plate opening 3 corresponding another ring plates; The opening part section 5 of described two ring plates, except that its inner ring surface 6, its excess-three face all extends to the section part of opening with the structural type of arc-shaped transition, and forms an arc transiting surface at its section.The seal ring of above-mentioned this scheme uses on two-cycle engine best, and cylinder liner is enterprising to adapt to, the needs of exhaust port.

Fig. 3,4,5 is depicted as another embodiment of the present utility model, and seal ring shown in the figure is made up of three mutual stacked ring plates; Respectively be provided with on the upper and lower surface of ring plate 7 in the middle of it one with two ring plates that match 9 up and down on the positioning boss 8 that matches of opening 10 width.

Claims
