Abstract
The utility model discloses a double-ball bearing turbocharger which comprises the following components: a rotor shaft which is provided with a turbine and an impeller, an intermediate and a pressure enlarging plate. The rotor shaft is supported in the intermediate by a first bearing and a second bearing. The first bearing and the second bearing are mixing angle contact ceramic ball bearings. Furthermore a spacing spring sleeve is set between the first bearing and the second bearing. The constant space spring sleeve is internally provided with a spring. The intermediate is provided with an oil inlet which is provided with an oil inlet positioning pin. Furthermore the oil inlet is connected with a lubricant passage which is communicated with the spacing spring sleeve. The double-ball bearing turbocharger has the following advantages: simple structure; quickened starting response speed; greatly improved accelerating performance, power performance and operating feeling of vehicle; low requirement for lubricant and prolonged actual life because of lower friction of ball bearing.
Description
Technical field
The utility model 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.
The model utility content
The purpose of this utility model is to provide a kind of pair of ball bearing turbosupercharger, and it has simple in structure, and speed of response is fast, the characteristics of bearing long service life.
The purpose of this utility model 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.
The beneficial effects of the utility model are, 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 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 simultaneously greatly, having improved the working life of pressurized machine, is that very big attraction force is arranged on market.
Description of drawings
With embodiment the utility model 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 utility model;
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 utility model.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.
