Abstract
The invention discloses a turbocharger with double ball bearings, which comprises a rotor spindle with a turbine and an impeller, an intermediate body and a diffusion board, wherein the rotor spindle is supported by a first bearing and a second bearing to be arranged in the intermediate body; the first bearing and the second bearing are mixing angle contact ceramic ball bearings; a distance spring housing is arranged between the first bearing and the second bearing; a spring is arranged in the distance spring housing; a fuel feed hole is arranged on the intermediate body; a fuel feed locating pin is arranged on the fuel feed hole; and the fuel feed hole is connected with a lubricant passage communicated with the distance spring housing. The turbocharger with double ball bearings has the advantages that the structure is simple; the starting response speed is accelerated; the acceleration performance, the kinaesthetic and the operating feeling of vehicles can be greatly improved; and the requirements on lubricating oil are low and the actual life is enhanced because the friction of the ball bearings is less.
Description
Technical field
The present invention relates to a kind of turbosupercharger, particularly a kind of pair of ball bearing turbosupercharger.
Background technique
The waste gas that turbosupercharger relies on motor to discharge promotes, and not only operating temperature is very high, and the rotating speed of rotor is also high, can reach per minute tens0000 commentaries on classics.So high rotating speed and temperature makes common mechanical needle roller or ball bearing can't be working rotor, therefore exhaust-gas turbocharger generally adopts the full floating bearing at present, be lubricated and cool off by machine oil, the wholly floating bearing is certain radial clearance between axle and the axle sleeve, and the lubricant oil by certain pressure floats rotor entirely.The rotor bearing of pressurized machine is to support pattern in adopting, and the full-floating type axle has two floating bearings usually in two end supports in the intermediate between two impellers, and the axial force of rotor is born by the thrust bearing end face.The pressurized machine of full floating bearing structure has a shortcoming, it is exactly the hysteresis quality of supercharging, the reason that causes this situation be since the inertia of supercharger rotor and frictional force action make its to vehicle accelerator when rapid reacting condition slow, thereby make motor postpone to increase output power, be embodied in unexpected acceleration or when overtaking other vehicles, moment has the sensation of putting forward not energetically, simultaneously because the friction of floating bearing is bigger, working life is short, and to the requirement height of lubricating oil.
Summary of the invention
The object of the present invention is to provide a kind of pair of ball bearing turbosupercharger, it has simple in structure, and speed of response is fast, the characteristics of bearing long service life.
The objective of the invention is to be achieved through the following technical solutions:
A kind of pair of ball bearing turbosupercharger, it comprises the rotor shaft that turbine and impeller are installed, intermediate, the diffusion plate, described rotor shaft is arranged in intermediate by the clutch shaft bearing and second bearings, and wherein, the described clutch shaft bearing and second bearing are ball bearing, and be provided with the spacing spring housing between the described clutch shaft bearing and second bearing, be provided with spring in the described spacing spring housing.
Described ball bearing is a mixing angle contact ceramic balls bearing.
Described intermediate is provided with oil inlet hole, and described oil inlet hole is provided with the oil-feed locating stud, and described oil inlet hole connects the oil leab that is connected with the spacing spring housing.
Beneficial effect of the present invention is, described pair of ball bearing turbosupercharger compared with the full floating bearing turbosupercharger that generally adopts now, starting response performance obviously improves, can improve 35% speed of response, because it is the friction of ball bearing is still less, low to the also more common floating bearing of the requirement of lubricating oil, also improve 30% actual life, simultaneously having improved vehicle accelerating ability energy, kinaestheic and manipulation sense greatly, is that very big attraction force is arranged on market the working life of having improved pressurized machine.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the two ball bearing turbosupercharger of the present invention;
Among the figure:
1, rotor shaft; 2, impeller; 3, turbine; 4, diffusion plate; 5, intermediate; 6, ball bearing; 7, spacing spring housing; 8, spring; 9, oil-feed locating stud; 10, oil leab.
Embodiment
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of the two ball bearing turbosupercharger of the present invention.In present embodiment, a kind of pair of ball bearing turbosupercharger, it comprises rotor shaft 1, turbine 3 and impeller 2 are installed on the described rotor shaft 1, and the outer installment of described rotor shaft 1 has passive intermediate 5, on the described intermediate 5 diffusion plate 4 is installed, described rotor shaft 1 is supported by two ball bearings 6 and is arranged in intermediate 5, and the axial force of bear rotor axle 1 generation, described ball bearing 6 is mixing angle contact ceramic balls bearing, and be provided with spacing spring housing 7 between described two ball bearings 6, described spacing spring housing 7 plays the fixedly effect of ball bearing 6 outer rings, and be provided with spring 8 in the described spacing spring housing 7, impact and vibrations that ball bearing 6 is axial can have been prevented, prolong the working life of ball bearing 6 greatly, described intermediate 5 is provided with oil inlet hole, described oil inlet hole is provided with oil-feed locating stud 9, described oil-feed locating stud 9 is used for the configuration of oil inlet quantity and spacing spring housing 7 is positioned, and described oil inlet hole connects the oil leab 10 that is connected with spacing spring housing 7.
Described pair of ball bearing turbosupercharger compared with existing general full floating bearing, starting response performance obviously improves, in the practical application, common pressurized machine is undertaken by the method can improving 35% speed of response behind the remodeling of ball ceramic bearing, because the friction of ball bearing still less, low to the also more common floating bearing of the requirement of lubricating oil, also improve 30% actual life, vehicle accelerating ability energy, kinaestheic and manipulation sense have been improved greatly, improved the working life of pressurized machine, very big attraction force has still been arranged on market.
