Abstract
The utility model relates to a gasoline engine turbo charger floating bearing spacer, characterized by: including the spacer body, the spacer body be the cavity column, and edge spacer body radially is equipped with the through -hole on the spacer body, the upper end and the lower extreme of spacer body set up the enhancement hoop respectively. The diameter of strengthening the hoop is greater than the diameter of spacer body. Gasoline engine turbo charger floating bearing spacer, to the design of gasoline engine turbo charger, the quality is reliable, can effectively improve the life -span of booster, the pollution abatement.
Description
Technical field
The utility model relates to a kind of floating bearing spacer, especially a kind of turbocharger for gasoline engine floating bearing spacer.
Background technique
Current China petrol engine motor 90 percent is not with turbosupercharger, and national requirements all must be with turbosupercharger to all manufacturers in 2016, and 1.2T, 1.4T, 1.5T, 1.6T, 1.8T and 2.0T as test-manufactured at present produce in batches.Turbocharger for gasoline engine and Turbochargers in Diesel Engines are completely different, and turbocharger for gasoline engine volume is little, and rotating speed is high, and temperature is high, and technical requirements is high.And the general floating bearing back-up ring that adopts in existing Turbochargers in Diesel Engines, but floating bearing back-up ring is yielding, damage.There is the form adopting floating bearing spacer in some Turbochargers in Diesel Engines at present, but due to the difference of Turbochargers in Diesel Engines and turbocharger for gasoline engine, existing Turbochargers in Diesel Engines floating bearing is not suitable for turbocharger for gasoline engine yet.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of turbocharger for gasoline engine floating bearing spacer, and for turbocharger for gasoline engine, reliable in quality, improves pressurized machine life-span, decreasing pollution.
According to the technological scheme that the utility model provides, described turbocharger for gasoline engine floating bearing spacer, is characterized in that: comprise spacer body, and spacer body is hollow columnar, and spacer body is provided with through hole along the radial direction of spacer body; In the top and bottom of described spacer body, Reinforced Hoop is set respectively.
In an embodiment, the diameter of described Reinforced Hoop is greater than the diameter of spacer body.
In an embodiment, described spacer body is hollow cylindrical.
In an embodiment, described spacer body is hollow hexagonal column.
In an embodiment, the adjacent edge in adjacent two faces of outer surface of described spacer body arranges chamfering or fillet.
In an embodiment, described through hole extends to another longitudinal edge relative with this longitudinal edge by a longitudinal edge of spacer body outer surface.
Turbocharger for gasoline engine floating bearing spacer described in the utility model, for turbocharger for gasoline engine design, reliable in quality, effectively can improve the life-span of pressurized machine, decreasing pollution.

Sequence number in figure: spacer body 1, through hole 2, Reinforced Hoop 3.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
Embodiment one: a kind of turbocharger for gasoline engine floating bearing spacer
As shown in Figure 1 and Figure 2, the utility model comprises spacer body 1, and spacer body 1 is hollow cylindrical, and spacer body 1 is provided with through hole 2 along the radial direction of spacer body 1; Because the rotating speed of turbocharger for gasoline engine is high, technical requirements is high, and in order to ensure the quality of bearing spacer, arrange Reinforced Hoop 3 respectively in the top and bottom of described spacer body 1, the diameter of this Reinforced Hoop 3 is greater than the diameter of spacer body 1.
Embodiment two: a kind of turbocharger for gasoline engine floating bearing spacer
As shown in Figure 3, Figure 4, the utility model comprises spacer body 1, and spacer body 1, in hollow columnar, spacer body 1 is provided with through hole 2 along the radial direction of spacer body 1; The cross section of this spacer body 1 is regular hexagon, arranges chamfering or fillet at the adjacent edge in adjacent two faces of the outer surface of spacer body 1;
As shown in Figure 4, described through hole 2 extends to another longitudinal edge relative with this longitudinal edge by a longitudinal edge of spacer body 1 outer surface.
Working principle of the present utility model: in use, spacer body 1 two ends are connected with floating bearing respectively, and the through hole 2 on spacer body 1 can be used as oilhole.Floating bearing spacer described in the utility model is not yielding, damage, and be applicable to turbocharger for gasoline engine, reliable in quality, the life-span is long.
