Abstract
The utility model provides an eccentric dual-ring anti-wear embedded ring belonging to a prefabricated part used for aluminum alloy piston. The utility model is provided with a ring trough embedded ring which is fixed with a combustion chamber mouth embedded ring which is eccentrically arranged on the ring trough embedded ring; the embedded ring can be positioned into a die and be cast into a whole with the piston when the piston roughcast is cast; after the manufacture is finished, the ring trough embedded ring is arranged at a first ring trough which is formed by mechanical processing; the combustion chamber mouth embedded ring is arranged at the combustion chamber mouth; a combustion chamber mouth wall is formed by mechanical processing; when in use, the ring trough embedded ring has functions of improving the wear resistance of the first ring trough and the work reliability of the piston-piston ring friction pair; the combustion chamber mouth embedded ring has crack function of the combustion chamber mouth, thus largely prolonging the service life of the piston.
Description
Technical field
The utility model provides a kind of prefabricated component that is used for all-aluminium piston, especially a kind of edge circle.
Background technique
Along with the development of motor, also more and more higher to performance, the quality requirement of motor " heart " part piston to high-power, low oil consumption, low noise and low emission.Traditional single all-aluminium piston is difficult to meet the demands, what have outstanding performance is that piston first groove wear is fast, thermal fatigue cracking takes place in piston combustion bowl mouth wall under high heat load and high mechanical load effect, cause gas blowby, pull-cylinder phenomena, influences the usability and the working life of piston.A kind of monocycle shape edge circle is arranged now, makes by alloy cast iron, when the cast pistons blank, put into mould and with the piston cast solid, the edge circle is positioned at the first annular groove place, makes first annular groove of finishing back formation piston.During use, can play the effect that improves the first annular groove wear resistance and piston one piston ring friction pair functional reliability.But the cracking problem that piston chamber's mouth takes place is not resolved.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of eccentric dicyclo abrasion-proof inserted ring is provided, and it can play and improve the first annular groove wear resistance, can play the effect that prevents the burner port cracking again.
The utility model is achieved in that a kind of eccentric dicyclo abrasion-proof inserted ring, and it has inlaid ring of ring slot, also is fixed with burner port edge circle on described inlaid ring of ring slot, and burner port edge circle is eccentric in inlaid ring of ring slot.
Adopt a kind of eccentric dicyclo abrasion-proof inserted ring of said structure, can be by putting into mould when the cast pistons blank and with the piston cast solid, after manufacturing is finished, inlaid ring of ring slot is positioned at the first annular groove place, after machining, constitute first annular groove, burner port edge circle is positioned at the burner port place, constitutes the burner port wall after machining.During use, inlaid ring of ring slot plays the effect that improves the first annular groove wear resistance and piston one piston ring friction pair functional reliability, and the burner port edge encloses the effect of burner port cracking, thus the working life of having improved piston greatly.

Fig. 2 is its plan view.
Fig. 3 is the main pseudosection of original edge coil structures.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates structure of the present utility model.
As shown in Figure 1 and Figure 2, a kind of eccentric dicyclo abrasion-proof inserted ring of the utility model, it has inlaid ring of ring slot (2), also is fixed with burner port edge circle (1) on described inlaid ring of ring slot (2), and burner port edge circle is eccentric in inlaid ring of ring slot.
Described inlaid ring of ring slot (2) is fixed together by connecting tendon (3) with burner port edge circle (1).
Burner port edge circle is eccentric in the concrete degree of eccentricity of inlaid ring of ring slot, can determine according to the needs of piston structure.
The edge circle of the utility model can be made by wear resisting cast iron such as high-nickel austenitic cast iron.
Specification of the present utility model, size can adjust as required.
As shown in Figure 3, original edge coil structures is the monocycle shape, promptly has only inlaid ring of ring slot (4).
Claims (2)
1, a kind of eccentric dicyclo abrasion-proof inserted ring, it has inlaid ring of ring slot (2), it is characterized in that, also is fixed with burner port edge circle (1) on described inlaid ring of ring slot (2), and burner port edge circle is eccentric in inlaid ring of ring slot.
2, a kind of eccentric dicyclo abrasion-proof inserted ring as claimed in claim 1 is characterized in that, described inlaid ring of ring slot (2) is fixed together by connecting tendon (3) with burner port edge circle (1).
