Description
Technical field
The utility model relates to technical field of engines, specifically is a kind of positioning means that is used for the turbosupercharger of motor.
Background technique
The machine that turbosupercharger is made up of turbine chamber and pressurized machine is actually a kind of air compressor, increases air inflow by pressurized air.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, and turbine drives coaxial impeller again, and the air that the impeller force feed is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, impeller just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor just can increase the output power of motor.When turbocharger operation, air is entered by intake duct, and under the effect of impeller blade, and then active wheel is made high speed rotating together, so air is compressed under action of centrifugal force.The air that flows out active wheel converts kinetic energy to the pressure energy by Diffuser, thereby improves gas pressure.Wherein, the blade mechanism of turbosupercharger and the volute of turbosupercharger generally adopt the setting sleeve structure, promptly tighten at the block plate of turbosupercharger and be combined with setting sleeve, setting sleeve screws on the volute of turbosupercharger again, thereby realizes the axially locating of blade mechanism.But there is following shortcoming in this position structure: owing to used setting sleeve, need each mating face of processing and fitting surface, make the processing technology complexity like this, thereby cause the increase of product cost.
The model utility content
Technical problem to be solved in the utility model is a kind of processing technology and simple in structure to be provided, and can to reduce the positioning means of the turbosupercharger of product cost.
For solving the problems of the technologies described above, the positioning means of a kind of turbosupercharger that the utility model provides, comprise impeller mounting disc 2, block plate 3, thermal baffle 5, described impeller mounting disc 2 is fixedlyed connected with block plate 3, described block plate 3 is fixedly connected on the turbine volute 1, described thermal baffle 5 is between impeller mounting disc 2 step surfaces 6 and turbine volute 1, the positioning means of described turbosupercharger also comprises compressing tablet spring 4, one end of described compressing tablet spring 4 pushes against on the step surface 6 of impeller mounting disc 2, and the other end pushes against on turbine volute 1.
After adopting above structure, the utility model compared with prior art, have the following advantages: the compressing tablet spring that adopts in the utility model has replaced setting sleeve of the prior art, only need during use the compressing tablet spring is contained between the step of impeller mounting disc and the turbine volute and get final product, need not to be tightened on the turbine volute with setting sleeve, that is to say, need not the screw thread that processing cooperates with setting sleeve on the turbine volute, also need not to use setting sleeve, therefore, the positioning means of the utility model turbosupercharger is simple in structure, and processing technology is also simple, thereby can reduce the cost of product.
As improvement, described compressing tablet spring 4 is the dish shape at the no end, its large diameter edge is provided with a plane 4.2, and described plane 4.2 pushes against on the step surface 6 of impeller mounting disc 2, the edge of its minor diameter be at the bottom of the dish 4.1 between turbine volute 1 and thermal baffle 5 and push against on turbine volute 1.After adopting the compressing tablet spring of this dish shape, make the axially locating of blade mechanism simpler.
