Abstract
Disclosed is a gas compressor used for a turbocharger, comprising a gas compressor shell 1, an impeller cover 2, a diffuser 3 and a gas compressor wheel 5; wherein the gas compressor wheel 5 includes an inducer 51 and a gas compression impeller 52; a circular connecting flange is arranged on the inner circles of the contact ends of the gas compressor with the impeller cover 2 and the diffuser 3. In the technical proposal adopted for the utility model, a circular connecting flange is arranged on the inner circle of the gas compressor shell, while the impeller cover and the diffuser are respectively fixed at both sides of the circular connecting flange, thereby the stress on the diffuser or the impeller cover is reduced, the diffuser and the impeller are prevented from being broken by bearing the other part; the stress on the impeller cover and the diffuser is more reasonable, so that the impeller cover is prevented from vibration because of uneven stress to scrape the gas compressor wheel.
Description
Technical field
The utility model relates to a kind of gas compressor, is specifically related to a kind of gas compressor of turbosupercharger.
Background technique
The structure of existing turbocharger air compressor part generally has dual mode: a kind of is that Diffuser is connected on the compressor casing, impeller chimney then is connected on the Diffuser with cantilevered fashion, this moment, Diffuser will bear the gravity of impeller chimney, might be because of the stressed unreasonable Diffuser fracture that causes, impeller chimney also may be owing to cantilever support is shaken the scratch air compressor wheel during work; Another kind is that impeller chimney leans on an end flange to be connected on the cartridge housing, and Diffuser then is connected on the flange of the impeller chimney the other end, so also may produce above-mentioned consequence as a same reason.
Summary of the invention
The purpose of this utility model is to provide a kind of turbocharger air compressor, uses this turbocharger air compressor to have the following advantages:
1. can reduce the stressed of Diffuser or impeller chimney, prevent to rupture because of the load that bears the other side.
2. make it stressed more reasonable, prevent that impeller chimney is because of the stressed unreasonable scratch air compressor wheel of shaking.
To achieve these goals, the technical solution adopted in the utility model is: a kind of gas compressor that is used for turbosupercharger, comprise compressor casing, impeller chimney, Diffuser and air compressor wheel, described compressor casing is being provided with and compressor casing all-in-one-piece annular adpting flange with impeller chimney and Diffuser surface of contact, and impeller chimney and Diffuser are separately fixed at the both sides of compressor casing annular adpting flange by fixing bolt.
As a kind of improvement, the annular adpting flange of described compressor casing is provided with several tapped hole that evenly is laid staggeredly and unthreaded holes, the plane that described Diffuser is connected with annular adpting flange is provided with several tapped holes of evenly laying, unthreaded hole on tapped hole and the annular adpting flange adapts, and Diffuser is fixed on a side of annular adpting flange by bolt being screwed in tapped hole; Described impeller chimney is provided with staggered macropore and the aperture of evenly laying, tapped hole on aperture and the annular adpting flange adapts, impeller chimney is fixed on the opposite side of annular adpting flange by bolt being screwed in aperture, the unthreaded hole of macropore and annular adpting flange adapts, and is used to avoid the hexagon head of Diffuser fixing bolt.
As a kind of improvement, be provided with the circular orientation boss with the plane that is connected that Diffuser matches on the described annular adpting flange, described Diffuser connects the plane and is provided with the circular orientation groove, and described circular orientation boss and circular orientation groove adapt.
As a kind of improvement, described Diffuser cooperates the plane to be provided with locating stud with compressor casing.
As a kind of preferred, described air compressor wheel comprises inducer and compression impellor, and the negative camber of outer meridian plane of air compressor wheel and impeller chimney matches.
The utility model is owing to adopt technique scheme, at the compressor casing inner ring an annular adpting flange is set, and impeller chimney and Diffuser be fixedly installed on annular adpting flange both sides respectively, and so just reduced the stressed of Diffuser or impeller chimney, prevent to rupture because of the load that bears the other side; Simultaneously also make impeller chimney and Diffuser more reasonable stress, prevent that impeller chimney is because of the stressed unreasonable scratch air compressor wheel of shaking.
