Abstract
Disclosed is a two-piece shaft assembly for a driven turbocharger with a traction drive. The turbo shaft is attached to a turbine and compressor, and is inserted into a traction barrel that has traction surfaces to mate to the traction drive. In this way, the traction drive can be assembled with only the traction barrel, and the turbo shaft can be inserted through the barrel at the end to simplify assembly.
Claims22
A driven turbocharger for an engine system comprising:
- a continuous turbo shaft that rotates in said driven turbocharger to transfer rotational mechanical energy:
- a traction drive comprising:
- a traction barrel coaxially surrounding and connected to said continuous turbo shaft such that an inner surface of said traction barrel forms an opening through which said continuous turbo shaft is inserted, said traction barrel is formed of a single component, and an outer surface of said traction barrel comprising at least one barrel traction surface;
- at least one roller with at least one roller traction surface in contact with said at least one barrel traction surface to form a traction interface that transfers torque between said traction barrel and said at least one roller;
- a turbine mounted to a first portion of said continuous turbo shaft;
- a compressor mounted to a second portion of said continuous turbo shaft said first portion of said continuous shaft located on a first side of said traction drive and said second portion of said continuous turbo shaft located on a second side of said traction drive, so that said continuous shaft can be inserted through said traction drive and said traction barrel prior to connecting either or both of said turbine or said compressor to said continuous shaft.

A method of assembling a driven turbocharger comprising:
- assembling a traction drive with a traction barrel to create a traction interface between said traction drive and said traction barrel that rotate together as a single part:
- inserting a turbo shaft having a continuous single shaft through a central opening in said traction barrel so that said continuous turbo shaft is concentrically located in said traction barrel;
- securing said continuous turbo shaft to said traction barrel so that torque can be transmitted between said continuous turbo shaft and said traction drive;
- attaching a turbine to a first portion of said continuous turbo shaft on a first side of said traction drive;
- attaching a compressor to a second portion of said continuous turbo shaft on a second side of said traction drive that is opposite to said first side.
