Abstract
A supercharger transmission case that includes both small and large impeller shaft bearing bores in a single component to avoid potential misalignment, and to allow the bores to be machined during the same machining setup by the same tool. The supercharger transmission case may be fabricated of low thermal expansion material, such as a hypereutectic metal matrix comprising aluminum and silicon, to further reduce thermal expansion of the transmission case and bearings.
Claims7
A supercharger transmission case comprising:
- a forward impeller shaft bearing bore machined into the forward surface of a main body of the transmission case, said forward impeller shaft bearing bore sized for receiving a forward impeller shaft bearing;
- a rear impeller shaft bearing bore machined into a bridge portion of said transmission case, said rear impeller shaft bearing bore sized for receiving a rear impeller shaft
- bearing, said bridge positioned rearward of and spanning said forward impeller shaft bearing bore.
