Description

Technical Field

[0001] The utility model relates to the technical field of supercharger impeller equipment, in particular to a turbocharger impeller. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller, which pressurizes the air sent from the air filter pipe and pressurizes it into the cylinder.

[0003] The patent with publication number CN207437133U, entitled "A turbocharger impeller," discloses a turbocharger impeller comprising a connecting shaft, a baffle fixedly connected to the right side of the connecting shaft, a casing fixedly connected to the right side of the baffle, an impeller body sleeved on the surface of the casing, an inner cavity of the casing provided with a telescopic rod, the telescopic rod comprising a shell, an inner cavity of the shell provided with a lifting rod, the bottom of the lifting rod fixedly connected to a limit plate, the top of the limit plate extending to the outer side of the shell. The utility model solves the problem of the inconvenience of installing the impeller of the existing turbocharger by providing a connecting shaft, a limit plate, a ball bearing, a positioning block, a shell, a connecting rod, a slide groove, a slider, a spring, a telescopic rod, a lifting rod, a limit plate, a shell, an impeller body, a positioning groove, and a slide rod, thereby facilitating the use of the user and improving the efficiency of the user's disassembly. This patented technology has shortcomings in its actual application. During the continuous use of the turbocharger, the impeller, as the main working component, is easily damaged by the continuous compression of air. When one of the impellers of the device is damaged, the entire impeller will be discarded, resulting in a waste of resources. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a turbocharger impeller.

[0006] A turbocharger impeller comprises a first impeller disc and a limiting shell, wherein the upper surface of the first impeller disc is provided with several concave grooves, the interiors of the several concave grooves are slidably connected with convex sliders, the upper surface of the convex sliders are fixedly connected with impeller blades, slots are provided on both sides of the upper surface of the limiting shell, bolts adapted to the slots are fixedly connected on both sides of the upper surface of the first impeller disc, and fixing nuts are threadedly sleeved on the surfaces of the bolts.

[0007] As a further improvement of the present invention, the upper surface of the first impeller disc is fixedly connected with a disc opening, and the upper surface of the limiting shell is provided with a mounting groove.

[0008] As a further improvement of the present invention, a plurality of limiting grooves are provided on the surface of the wheel disc mouth, and one end of the impeller blade is fixedly connected to a limiting block adapted to the limiting groove.

[0012] Beneficial effects of the utility model:

[0013] By providing a concave slide groove and a convex slider, when in use, the impeller blade is inserted into the concave slide groove of the first impeller disc through the convex slider until the limit block on the impeller blade is inserted into the limit groove on the disc mouth, so that the device can easily disassemble and install the impeller blade. When an impeller of the turbocharger is damaged during use, the damaged impeller can be directly disassembled without discarding the entire impeller, thereby increasing the practicality of the device.

[0014] By setting a limit shell, when in use, after all impeller blades are installed, the slots of the limit shell are aligned with the bolts on the first impeller disc, so that the limit shell is sleeved onto the first impeller disc, and then the limit shell is fixed to the first impeller disc using the fixing nut, so that the device can limit the impeller blades to the first impeller disc through the limit shell, thereby avoiding dislocation of the impeller blades when the turbocharger is working.
