Title:
SINGLE ANGULAR CONTACT BALL RAMP FOR MECHANICAL TURBOCHARGER
Document Type and Number:
Japanese Patent JP2019183840
Kind Code:
A
Abstract:
To improve a mechanical turbocharger.SOLUTION: There is disclosed a planetary traction drive for a mechanical turbocharger that utilizes angular contact ball ramps to provide variable clamping depending on a torque quantity. The ball ramps are located between ring rollers and a ring gear and function to locate the ring gear concentrically with the ring rollers. Inclined contact axes of the ball ramps allows use of a low conformity contact between balls and ball races in the ball ramps to provide efficient movement, while simultaneously locating the ring gear concentrically with traction rings. There is also disclosed a variation where only a single angular contact ball ramp is used between the ring gear and a clamping traction ring, and the other traction ring is rigidly fixed to the ring gear to reduce the number of components and complexity.SELECTED DRAWING: Figure 2
