Background
A turbocharger, which is a kind of air compressor, increases the intake air amount by compressing air. A seal cover structure for a turbocharger is characterized in that after a seal ring is arranged in a seal groove of the seal cover, the seal cover is assembled on a turbine shaft and then arranged in the turbocharger, and the seal cover and the seal ring play a role in preventing oil leakage.
Among the prior art, generally seal to turbo charger and all seal through seal cover and oil blanket and form, but to the sealed effect of seal cover and oil blanket, when turbo charger was in when operation under low-speed and low-load operating mode, the impeller back can form the negative pressure state, and gas pressure is less than atmospheric pressure, still appears the oil leakage condition easily.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a defect to prior art provides a seal cover for turbo charger to this oil leak problem of solving and producing in turbo charger low-speed and low-load operating mode operation process.
In order to solve the technical problem, the utility model provides a technical scheme as follows:
the utility model provides a seal cover for turbo charger, includes consecutive sealing, gets rid of oil portion and connecting portion, be equipped with the seal groove that is used for installing the sealing ring on the circumference surface of sealing, its characterized in that: the one end that is close to getting rid of oil portion on the circumference surface of sealing is provided with first oil groove of getting rid of, first oil groove of getting rid of is an annular groove, the circumference diameter of getting rid of oil portion is greater than sealing and connecting portion.
Further, the depth of the first oil slinger is gradually deepened along the direction towards the oil slinger.
Furthermore, get rid of the oil portion and be close to evenly distributed is provided with a plurality of second and gets rid of the oil groove on the one side of first oil groove of getting rid of.
Further, the quantity of second oil slinger is 8, and the degree of depth is 0.01mm, and the shape size is all unanimous.
Furthermore, the sealing part is tubular, the sealing grooves are circular, and at least two sealing grooves are axially arranged at intervals along the sealing part.
Further, a tubular cavity for connecting the turbine shaft is formed in the sealing part, the oil slinging part and the connecting part.
Compared with the prior art, the beneficial effects of the utility model are that: increase the first oil groove of getting rid of through the design to get rid of the oil groove at the first second that gets rid of oil groove limit and not increase laser etching and get rid of the oil groove, turbo charger is under low-speed and low-load operating mode, and the second gets rid of the oil groove and plays the effect that improves anti negative pressure, and absorbent oil can flow into first get rid of the oil groove in, thereby improved turbo charger's mechanical seal structure's anti oily ability of leaking.

Detailed Description
In order to deepen the understanding of the present invention, we will make further details of the present invention with reference to the drawings, and this embodiment is only used to explain the present invention, and does not constitute a limitation to the protection scope of the present invention.
Fig. 1-3 show a specific embodiment of a sealing sleeve for a turbocharger, including consecutive seal portion 1, get rid of oil portion 2 and connecting portion 3, be equipped with the seal groove 11 that is used for installing sealing ring 4 on the circumference surface of seal portion 1, be provided with first oil groove 5 of getting rid of on the circumference surface of seal portion 1 near getting rid of one end of oil portion 2, first oil groove 5 of getting rid of is an annular groove, gets rid of the circumference diameter of oil portion 2 and is greater than seal portion 1 and connecting portion 3.
Preferably, the depth of the first oil slinger 5 is gradually deepened in a direction towards the oil slinger 2. Get rid of oil portion 2 and be close to evenly distributed on the one side of first oil groove 5 and be provided with a plurality of second and get rid of oil groove 21. The number of the second oil throwing grooves 21 is 8, the depth is 0.01mm, and the shapes and the sizes are all consistent. The sealing part 1 is tubular, the sealing groove 11 is annular, and two sealing grooves 11 are arranged at intervals along the axial direction of the sealing part 1. A tubular cavity 6 for connecting the turbine shaft 7 is formed in the seal portion 1, the oil slinger 2, and the connecting portion 3.
As shown in fig. 4 and 5, when in use, the sealing sleeve is connected with the turbine shaft 7, then is arranged in the turbocharger, and is matched with the intermediate body 8 of the turbocharger through the connecting part 3 to be abutted against the bearing device on the turbine shaft 7; the oil slinger 2 is matched with an end cover 9 of the intermediate body 8 to prevent axial movement, the sealing part 1 is connected with the side of the compressor impeller 10, a flow path of lubricating oil in the intermediate body 8 is shown as an arrow in figure 4, and as can be seen from the figure, when the lubricating oil flows to the vicinity of the oil slinger 2 of the sealing sleeve, a negative pressure area formed in a second oil slinger groove 21 on the oil slinger 2 adsorbs the lubricating oil; then the absorbed lubricating oil flows into the first oil slinger 5 along the second oil slinger 21; finally, the lubricating oil collected in the first oil slinger 5 flows out from the lower end of the intermediate body 8, so that the lubricating oil is prevented from leaking out from the gap between the sealing ring 4 and the sealing groove 11 under the low-speed and low-load conditions of the turbocharger.
The foregoing detailed description of the embodiments is provided for the purpose of illustrating the technical concept and structural features of the present invention, and is not intended to limit the scope of the present invention, which is defined by the claims and the accompanying drawings.
