초록

A fixed ratio traction drive is disclosed that uses multidiameter planet rollers. The high speed traction drive provides speed reduction from a high speed shaft. A planet carrier is used to rotationally mount the multidiameter rollers. A continuously variable transmission that uses planetary ball traction is also disclosed that provides infinitely variable speed ratios.
