Description
Technical field
The utility model relates to technical field of engines, is specifically related to a kind of turbocharger of motor.
Background technique
Turbosupercharger, at raising engine power performance, reduces fuel consume, improves motor discharge aspect, played extremely important effect.Existing turbosupercharger generally includes turbine casing, compressor casing, intermediate, compressor casing and turbine casing are connected to intermediate both sides, couple axle is equipped with and couple axle two ends extend in turbine casing and compressor casing respectively in intermediate, one end that couple axle stretches into turbine casing is arranged with turbine, one end that couple axle stretches into compressor casing is arranged with impeller, is provided with floating bearing between intermediate and couple axle.But, in the turbosupercharger of existing use, floating bearing is normally directly installed between intermediate and couple axle, due to the rotation of couple axle in intermediate, floating bearing will be driven to rotate together, the wearing and tearing between intermediate and floating bearing will be caused like this, once intermediate is worn need the new intermediate that changes the outfit, not only cause great waste, and user cost is high, is not easy to maintenance and safeguards.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of turbocharger of motor, and this turbocharger of motor is rational in infrastructure, easy accessibility, can be good at the phenomenon avoiding wearing and tearing mutually between intermediate and floating bearing, is conducive to increasing the service life.
In order to solve the problem existing for background technique, the utility model have employed following technological scheme: a kind of turbocharger of motor, comprise turbine casing, compressor casing, intermediate, described compressor casing and turbine casing are connected to intermediate both sides, couple axle is equipped with and couple axle two ends extend in turbine casing and compressor casing respectively in described intermediate, one end that described couple axle stretches into turbine casing is arranged with turbine, one end that described couple axle stretches into compressor casing is arranged with impeller, floating bearing is provided with between described intermediate and couple axle, the wear-resistant bearing bush detachably installed is provided with between described floating bearing and intermediate, in described wear-resistant bearing bush, outer wall is closely conflicted with the outer wall of couple axle and the inwall of intermediate respectively, described couple axle is arranged with the spacing back-up ring that two are resisted against wear-resistant bearing bush two ends respectively.
By this setting, turbocharger of motor of the present utility model by being provided with wear-resistant bearing bush between floating bearing and intermediate, wear-resistant bearing bush can be good at avoiding intermediate and floating bearing mutually to produce the phenomenon of wearing and tearing, thus make intermediate and floating bearing not fragile, be conducive to the working life extending whole turbosupercharger, can reduce maintenance and the maintenance cost of turbosupercharger, the setting of spacing back-up ring can be good at the position limiting wear-resistant bearing bush simultaneously.
Further setting of the present utility model: described intermediate is provided with radial groove on the end face of impeller one end, and the cooperation of described impeller wheel portion root extend in described radial groove.
By this setting, thus turbosupercharger inside can be effectively stoped to produce the phenomenon of oil leak, not affect engine power performance and emission performance.
Further setting of the present utility model: the position on described couple axle between floating bearing and impeller is arranged with the thrust sleeve and thrust bearing that lean respectively, one end that described thrust sleeve deviates from thrust bearing is resisted against impeller, and one end that described thrust bearing deviates from thrust sleeve is resisted against spacing back-up ring.
By this setting, thrust sleeve and thrust bearing rotation and the stopping that more effectively can controlling couple axle are set, make the rotation of couple axle more stable, the phenomenon preventing the inner leakage of oil of turbosupercharger and gas blowby further can be played simultaneously.
Further setting of the present utility model: be fixedly connected with respectively by the Placement of bolt between described turbine casing and intermediate and between described compressor casing and intermediate.
By this setting, thus the installation and removal respectively and between intermediate of turbine casing, compressor casing can be made more convenient, also can increase the soundness connected between it simultaneously.
The beneficial effects of the utility model are: turbocharger of motor of the present utility model is rational in infrastructure, easy accessibility, can be good at the phenomenon avoiding wearing and tearing mutually between intermediate and floating bearing, are conducive to increasing the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of turbocharger of motor of the utility model.
