Abstract

The utility model discloses a ball bearing turbo charger, it relates to the engine technology field. Install turbine and impeller on the rotor shaft, the outside of rotor shaft is provided with the midbody, is provided with the diffusion board between impeller and the midbody, the rotor shaft by fuel feeding formula angular contact pottery ball bearing and floating bearing support position in the midbody, fuel feeding formula angular contact pottery ball bearing set up in the one side that is close to the impeller, and cooperate the ceramic ball bearing of fuel feeding formula angular contact to be provided with footstep bearing, is the thrust gasket below the footstep bearing, is elasticity thrust adjusting shim below the thrust gasket. It stable good is compared with the full floating bearing turbo charger of present ordinary adoption, and it can obviously improve to start the response, because ball bearing's small friction, also more ordinary floating bearing is low to the requirement of lubricated machine oil, and the actual life has also improved more than the one time, and it has still improved vehicle acceleration performance greatly simultaneously, and active power is done all can with controing.

Description

A kind of ball-bearing turbocharger

Technical field

The utility model relates to a kind of ball-bearing turbocharger, belongs to technical field of engines.

Background technology

Turbocharger relies on the waste gas that engine is discharged to promote, not only operating temperature is very high, and the revolution of rotor is also high, can reach per minute tens0000 turns, it cannot be working rotor that so high revolution and temperature make common needle bearing or ball bearing, therefore waste gas supercharger generally adopts full floating bearing at present, is lubricated with cooling by machine oil, and full floating bearing is between axle and axle sleeve, to have sizing item gap entirely by the lubricating oil of certain pressure, rotor to be floated. The rotor supports of booster is to adopt inner support form full-floating type axle in the intermediate between two blades, conventionally has two each and every one floating bearings in two end supports, and the axial force of rotor is born by thrust bearing end face. The shortcoming of the booster of full floating bearing arrangement is the rear property of booster, the reason that causes this situation is that while making it rapid to vehicle accelerator due to the inertia of supercharger rotor and frictional force effect, reacting condition is slow, thereby make engine postpone to increase power output, when being embodied in unexpected acceleration or overtaking other vehicles, moment has the sensation of putting forward not energetically, and the friction of floating bearing is larger, and service life is short, to lubricating oil require high.

Summary of the invention

For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of ball-bearing turbocharger.

Ball-bearing turbocharger of the present utility model, it comprises impeller, thrust bearing, thrust washer, pad is adjusted in elasticity thrust, oil feeding type angular contact ceramic balls bearing, intermediate, floating bearing, turbine, armature spindle, oil leab, bearing heat radiation oil duct and diffusion plate, turbine and impeller are installed on armature spindle, the outer setting of armature spindle has intermediate, between impeller and intermediate, be provided with diffusion plate, armature spindle is supported and is arranged in intermediate by oil feeding type angular contact ceramic balls bearing and floating bearing, oil feeding type angular contact ceramic balls bearing is arranged at the side near impeller, and coordinate oil feeding type angular contact ceramic balls bearing to be provided with thrust bearing, it below thrust bearing, is thrust washer, below thrust washer, be that pad is adjusted in elasticity thrust.

As preferably, the axial force that pad bear rotor axle produces is adjusted in described thrust washer and elasticity thrust, and elasticity thrust is adjusted pad and played flexible and limit acceptably the centrifugal load of high rotating speed ball in the bearing race being passed over by bearing angular contact face.

As preferably, in described intermediate, be provided with respectively and oil feeding type angular contact ceramic balls bearing, the oil leab that floating bearing and thrust bearing are connected.

As preferably, the side near oil feeding type angular contact ceramic balls bearing on described intermediate is provided with bearing heat radiation oil duct.

As preferably, described oil feeding type angular contact ceramic balls bearing is connected with bearing heat radiation oil duct by bearing heat radiation oil duct oil-in, and is provided with bearing heat radiation oil duct oil-out on oil feeding type angular contact ceramic balls bearing.

The beneficial effects of the utility model: it simple in structure, good stability, compared with the full floating bearing turbocharger of present common employing, starting-up response performance obviously improves, in actual applications, can improve 25 percent response speed, and the thrust washer wherein arranging and elasticity are adjusted pad and have been played the axial driving force of inhibition, protect thrust bearing can realize zero wearing and tearing, because the frictional force of ball bearing is little, low to the requirement of lubricating oil also more common floating bearing, also be more than doubled actual life, it has also improved vehicle accelerating ability energy greatly simultaneously, dynamic power and steering force.
