Description

A kind of novel rotor axis
Technical field
The utility model is related to the component in a kind of turbocharger, more particularly to a kind of novel rotor axis.
Background technology
Turbocharger is that one kind of raising gasoline or diesel internal combustion acc power is attached under conditions of engine displacement is constant Feeder apparatus, vehicle turbocharger are mainly made of compressor, turbine and intermediate three parts.Armature spindle is threaded onto supercharging In device, turbine of the both ends respectively with the impeller of compressor and turbine is fixedly connected, and is passed through two floating bearings and be supported on In intermediate, the oil duct of lubrication and cooling bearing is equipped in intermediate, usual armature spindle offers at the position of installation turbine Cricoid seal groove, sealing shroud be mounted on seal groove in and it is opposing stationary with armature spindle, with prevent the lubricating oil in oil duct along The outer wall of armature spindle is leaked out on turbine.
For turbocharger in actual moving process, turbine rotation drives armature spindle rotation, armature spindle high-speed rotating wink Between sealing shroud still in stationary state so that relatively rotate between sealing shroud and armature spindle, in the process of long-time service Middle sealing ring and armature spindle can generate certain abrasion, and then cause to generate gap between sealing shroud and armature spindle, in intermediate Lubricating oil the rotation of turbine can be leaked out in turbine and influenced along the gap between sealing shroud and armature spindle.
Utility model content
The purpose of this utility model is to provide a kind of novel rotor axis, and which solve armature spindles of the prior art and sealing Set relatively rotates so that leading to the problem of gap between the two and causing oil leak.
The above-mentioned technical purpose of the utility model technical scheme is that:
A kind of novel rotor axis, including be wholely set successively turbine linkage section, bearing linkage section, impeller linkage section and Threaded connection section, offers cricoid seal groove on the turbine linkage section, circumferentially disposed on the both sides cell wall of the seal groove There are several limit protrusions and several limiting slots, the limit protrusion is arranged at intervals with limiting slot.
Using the above scheme, when in use, turbine is installed on turbine linkage section armature spindle, and bearing linkage section passes through floating Bearing is maked somebody a mere figurehead in intermediate, and impeller is usually installed on using clamp spring on impeller linkage section, and threaded connection section is used for reinforcing clip The fixation of spring, sealing shroud are installed in seal groove, and limit protrusion and limiting slot prevent relatively to turn between seal groove and sealing ring It is dynamic, to realize that armature spindle limits the circumferential direction of sealing ring so that sealing ring is in relative static conditions with armature spindle, reduces close The abrasion of seal avoids generating the leakage that gap causes lubricating oil between sealing ring and seal groove.
Further preferably:The side of cell wall of the limit protrusion far from the seal groove is opened up there are one groove.
Using the above scheme, temperature is higher in the process of running for usual booster, the sealing shroud meeting being installed on armature spindle Certain elastic deformation occurs and fills into groove, strengthens armature spindle and the circumferential direction of sealing shroud is limited.
Further preferably:Limit protrusion on the cell wall of the seal groove side and the limit on seal groove opposite side cell wall Position slot is oppositely arranged.
Using the above scheme, when sealing shroud is installed in limiting slot, limit protrusion compresses axially sealing shroud to limit In the slot of position, so that sealing shroud is in bending on the circumferential surface of armature spindle, and then with good circumferential position-limiting action.
Further preferably:The limit protrusion is spherical in semicircle.
Using the above scheme, the Surface of Sphere of limit protrusion plays guiding role when sealing shroud is installed, convenient for sealing shroud Fast Installation.
Further preferably:The limit protrusion is in strip, and the length direction of limit protrusion is connected for the turbine The diametric(al) of section.
Using the above scheme, the limit protrusion of strip is relatively large to the forced area of sealing shroud so that protrusion is given The active force of sealing shroud is uniformly distributed, and has good circumferential position-limiting action.
Further preferably:There are two the seal groove is arranged in parallel.
Using the above scheme, two seal grooves increase the approach of oil seepage relative to single seal groove, improve Turbocharger reduces production cost in the leakproofness of turbine linkage section relative to other multiple seal grooves, has good Practicability.
Further preferably:The impeller linkage section and the junction of the threaded connection section are provided with the first guide surface, The one end of the threaded connection section far from impeller linkage section is provided with the second guide surface.
Using the above scheme, the first guide surface and the second guide surface play guiding role to impeller, convenient for accelerating impeller Installation.
Further preferably:The impeller linkage section is provided with form friction pattern ring on the circumferential surface by close end.
Using the above scheme, impeller is mounted on impeller linkage section, and form friction pattern ring strengthens impeller and impeller linkage section Connection.
Further preferably:It is both provided on the circumferential surface of the turbine linkage section, bearing linkage section and impeller linkage section Wear-resistant coating.
Using the above scheme, the setting of wear-resistant coating slows down the abrasion of armature spindle, and then increase turbine linkage section Usage time.
In conclusion the utility model has the advantages that:
1st, it by the setting of limit protrusion, limiting slot and groove, realizes armature spindle and the circumferential direction of sealing ring is limited, make It obtains sealing ring and is in relative static conditions with armature spindle, reduce the abrasion of sealing ring, prevent to produce between sealing ring and seal groove Raw gap causes the leakage of lubricating oil;
2nd, by the setting of wear-resistant coating, the abrasion of armature spindle is slowed down, extends the usage time of armature spindle;
3rd, it by the setting of the first guide surface and form friction pattern ring, convenient for the Fast Installation of impeller, increases impeller and is mounted on Structural stability on armature spindle.
