Description
Technical field
The invention belongs to field of turbochargers, more particularly, to a kind of turbocharger adaptively correcting thrust bearing knot
Structure.
Background technology
During turbocharger operation, the combustion gas active force on turbine wheel and the air effect power on compressor impeller are uneven
It weighs and forms axial force.This axial force is just undertaken by thrust bearing.According to the operating condition of turbocharger and structure cloth
It puts, thrust bearing is generally located on generator terminal of calming the anger.Therefore, generator terminal of calming the anger will also other than setting bears radially to cut out the bearing of lotus
The thrust bearing of axial load is born in setting.Thrust bearing not only influences the mechanical efficiency of turbocharger, but also turbine is increased
Depressor can lever and service life influence it is very big.
Currently in turbocharger compared with frequently with a kind of typical Integral-structure type thrust bearing as shown in Figs. 1-3.
This monoblock type thrust bearing, bearing arrangement are simple.On front and rear working face, each there are four (or six) oil grooves.
They form four (or six) fan-shaped oil film wedge load planes, and each fan-shaped working face circumferentially processes 0.25~1 ° oblique
Oilhole is driven in face at fluting.Corresponding with working face before and after thrust bearing is two thrust plates, and axial load is born in formation
The bearing structure of lotus.Thrust plate working surface is smooth surface.And it is and the symmetrical revolving body in axle center.
Monoblock type thrust bearing is higher to processing and matching requirements, if there is machining accuracy or assembling poor quality, only
Push jack plane is bonded bad with thrust bearing working face, can destroy the normal work of thrust bearing, and thrust bearing can be seriously worn,
Even damage whole turbocharger.In addition, since floating-ring bearing is there are certain gap, booster is in operation process, axis
The out of plumb of neck center line and thrust plate plane, thrust plate plane are bonded bad with thrust bearing working face, also be easy to cause only
Thrust bearing damages.Therefore there is an urgent need to a kind of novel thrust bearings, being capable of automatic adjusument thrust plate plane and thrust bearing work
It is right to make face paste.
