Abstract
The utility model provides a stepped overlap piston ring, wherein, an interface of which is in one-way or two-way stepped overlap. The utility model has the evident advantages of simple machining, favorable closed performance, long life time, etc. The utility model is especially suitable for various motor vehicles of different types.
Description
The utility model relates to a kind of step shiplap piston ring, belongs to fields such as the internal-combustion engine that adopts reciprocating piston, aerostatic press.
At present mostly to adopt end face be the steel loop on plane to the piston ring of reciprocating piston because end face has end gap, easily and the gap of cylinder barrel and piston constitute leakage way, more serious, the performance of leakage, environmental protection index seriously descend after the wearing and tearing.Application number is 97213803, and the patent application that name is called " embedding envelope formula piston ring " discloses the technological scheme that embedding mounting and embedding sealing groove formation embedding sealing-in mouth are set respectively at the jointing of piston ring, and when heat expansion, interface embeds mutually, engages tightly, can not leak gas; Application number 97200843, name is called " a kind of joggle piston ring " patent application and discloses to encircle with notch overlap joint coupling at the bottom of the ring of the ring top tenon of ring body one end and the other end and enclose the piston ring that forms, and ring body lap-joint forms the structure that the tortuous circumferential weld of one group of faying surface is arranged again between two groups of involutory surfaces.Processing of the piston ring of these two kinds of structures and installation are all not too easy in the practice.
The purpose of this utility model is to provide a kind of step shiplap piston ring, to enhance productivity and further to improve sealing effect.
The technical solution of the utility model is achieved in that this step shiplap piston ring, interface be step shiplap.
The interface of described step shiplap piston ring can also be two-way step shiplap.
This step shiplap piston ring has easy to processly, and airtight performance is good, the long remarkable advantage that waits of life-span.Be particularly useful for various dissimilar motor vehicle.
Below in conjunction with embodiment and accompanying drawing describe in detail technology contents of the present utility model: Fig. 1 for the two-way step shiplap piston ring of the utility model schematic representation Fig. 2 for the A of Fig. 1 to view Fig. 3 for the B of Fig. 2 to sectional view Fig. 4 for the unidirectional step shiplap piston ring of the utility model schematic representation Fig. 5 for the A of Fig. 4 to view Fig. 6 for the B of Fig. 5 in sectional view figure:
1, piston ring 2, unidirectional ladder interface 3, two-way ladder interface
In actual applications, the utility model has two kinds of technological schemes, and two-way ladder interface 3 is one deck ladder to be set again with further raising sealing on the basis of unidirectional ladder interface 2.
Claims (2)
1, a kind of step shiplap piston ring is characterized in that piston ring joint is step shiplap.
2, step shiplap piston ring according to claim 1 is characterized in that piston ring joint is two-way step shiplap.
