Abstract
The utility model discloses a seal structure of no incision sealing ring and turbo charger, this no incision sealing ring include the sealing ring body, the sealing ring body is including being spiral helicine sealing strip, the one end of sealing strip is provided with first sealed end, just the other end of sealing strip is provided with the sealed end of second, first sealed end is in the ascending length of sealing ring body axial direction is followed the screw direction of sealing strip reduces in proper order so that the terminal surface of sealing ring body axial one end is planar structure, the sealed end of second is in the ascending length of sealing ring body axial direction is followed the screw direction of sealing strip increases in proper order so that the terminal surface of the sealing ring body axial other end is planar structure. The utility model discloses a no incision sealing ring does not have the axial incision, compares in prior art, the utility model discloses have more excellent sealing performance to can restrain the inside lubricated liquid of midbody in the turbo charger and reveal to the impeller end.
Description
Technical Field
The utility model relates to a turbo charger technical field especially relates to a seal structure of no incision sealing ring and turbo charger.
Background
The turbocharger is actually an air compressor that increases the intake air amount by compressing air. The engine uses the inertia impulse force of the exhaust gas from the engine to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller presses the air sent by the air filter pipeline, and the air is pressurized and enters the cylinder. When the rotating speed of the engine is increased, the exhaust gas exhaust speed and the rotating speed of the turbine are also increased synchronously, the impeller compresses more air to enter the air cylinder, the pressure and the density of the air are increased, more fuel can be combusted, and the output power of the engine can be increased by correspondingly increasing the fuel quantity and adjusting the rotating speed of the engine.
The impeller end of the turbocharger is a key area for product sealing, and a sealing ring with a notch is generally adopted for sealing at present, as shown in fig. 1, however, the sealing ring of the structure has poor sealing effect due to the existence of an axial notch, and the sealing structure is frequently subjected to oil leakage, so that the problem is urgently needed to be solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the above-mentioned problem, provide a no incision sealing ring and turbocharger's seal structure to solve the problem that proposes in the above-mentioned background art.
The utility model aims at realizing through the following technical scheme:
the utility model provides a no incision sealing ring, includes the sealing ring body, the sealing ring body is including being spiral helicine sealing strip, the one end of sealing strip is provided with first sealing end, just the other end of sealing strip is provided with the sealing end of second, first sealing end is in the ascending length of sealing ring body axial direction is followed the screw direction of sealing strip reduces in proper order so that the terminal surface of sealing ring body axial one end is planar structure, the sealing end of second is in the ascending length of sealing ring body axial direction is followed the screw direction of sealing strip increases in proper order so that the terminal surface of the sealing ring body axial other end is planar structure.
As an optimized proposal of the utility model, the whole sealing ring body is of a circular ring structure.
As an optimized scheme of the utility model, the sealing strip first sealing end the second sealing end structure as an organic whole.
A sealing arrangement for a turbocharger comprising a non-split sealing ring as described above.
The beneficial effects of the utility model are that, the utility model discloses a no incision sealing ring does not have the axial incision, compares in prior art, the utility model discloses have more excellent sealing performance to can restrain the inside lubricated liquid of midbody in the turbo charger and reveal to the impeller end.

FIG. 2 is a front view of a non-notched sealing ring of the present invention;
fig. 3 is a schematic view of a three-dimensional structure of a non-notched sealing ring according to the present invention.
In the figure:
1. a seal ring body; 2. a sealing strip; 3. a first sealed end; 4. a second sealed end.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the present invention and are not limiting thereof.
Referring to fig. 2 and 3, fig. 2 is a front view of a non-notched sealing ring according to the present invention; fig. 3 is a schematic view of a three-dimensional structure of a non-notched sealing ring according to the present invention.
In this embodiment, a no incision sealing ring, including sealing ring body 1, sealing ring body 1 is including being spiral helicine sealing strip 2, the one end of sealing strip 2 is provided with first sealing end 3, just the other end of sealing strip 2 is provided with the sealing end of second 4, first sealing end 3 is in the ascending length of sealing ring body 1 axial direction is followed the screw direction of sealing strip 2 reduces in proper order so that the terminal surface of the 1 axial one end of sealing ring body is planar structure, the sealing end of second 4 is in the ascending length of sealing ring body axial direction is followed the screw direction of sealing strip 2 increases in proper order so that the terminal surface of the 1 axial other end of sealing ring body is planar structure.
Specifically, in this embodiment, the whole sealing ring body 1 has a circular ring structure.
Specifically, in this embodiment, the sealing strip 2, the first sealing end 3, and the second sealing end 4 are integrated.
The utility model provides a no incision sealing ring does not have the axial incision, and it has better sealing performance, and sealing strip 2 adopts helical structure, compares in current sealing ring, and sealing ring body 1 is longer in the ascending length of axial direction, and sealing performance is more excellent to can restrain the inside lubricated liquid of midbody in the turbo charger and reveal to the impeller end.
The embodiment also discloses a sealing structure of a turbocharger, which comprises the sealing ring without the notch.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims.
