Abstract
A forced induction device for an internal combustion engine is provided, which includes a shaft, and a compressor wheel that is threadably mounted to the shaft, and a tool that is configured to engage one or more through bores in the compressor wheel to thread and unthread the compressor wheel onto and off of the shaft. The compressor wheel has a plurality of blades with leading edges that converge at an apex. The apex is aligned with a centerline of the shaft. The tool allows a technician to rotate the compressor wheel relative to the shaft to install or remove the compressor wheel from the shaft without applying any pressure to the blades of the compressor wheel. An associated assembly method is also provided.
Claims11
A forced induction device for an internal combustion engine, comprising:
- a compressor wheel having an internally threaded bore;
- a shaft extending co-axially about a centerline, the shaft having a threaded end that threads into the internally threaded bore of the compressor wheel to threadably mount the compressor wheel to the shaft;
- at least one through bore extending through the compressor wheel at a location that is offset from the centerline of the shaft;
- and
- a tool including at least one post that is configured to be received in the through bore in the compressor wheel so as to temporarily lock the tool in rotation with the compressor wheel and allow the compressor wheel to be rotated relative to the shaft during installation and removal of the compressor wheel.
A forced induction device for an internal combustion engine, comprising:
- a shaft extending co-axially about a centerline;
- a compressor wheel threadably mounter to the shaft;
- a turbine wheel mounted to the shaft;
- a housing that includes a turbine section for housing the turbine wheel and a compressor section for housing the compressor wheel, wherein the shaft is rotatably supported by the housing;
- at least one through bore extending through the compressor wheel at a location that is offset from the centerline of the shaft;
- and
- a tool including at least one post that is configured to be received in the through bore in the compressor wheel so as to temporarily lock the tool in rotation with the compressor wheel and allow the compressor wheel to be rotated relative to the shaft during installation and removal of the compressor wheel.
