Patent ID: 7491114

Claim:
A fiber optic polisher having one-degree-of-freedom gear transmission system comprises: a stationary base plate; a compound drive shaft supporting a respective driving sun gear and a primary driving pinion on one side and having a drive portion on another side; a primary planet shaft supporting an eccentric disc with an eccentric hole and supporting a planet gear interacting with said sun gear and each eccentric disk each having the same eccentricity amount; two secondary planet shafts each supporting a respective eccentric disc with an eccentric hole; a planetary carrier disposed in a rotatable combination with said compound drive shafts; a compound gear shaft supporting a respective large gear and a secondary driving pinion; wherein said planetary carrier has gear teeth, said compound drive shaft, its supported driving sun gear and a driving pinion is rotatable around its axis of rotation relative to said stationary base plate by said primary driving pinion engaging with said large gear, relative to said stationary base plate and said planetary carrier is rotatable around its axis of rotation by said secondary driving pinion engaging with said gear teeth on said carrier, relative to said stationary base plate, and said three planet shafts arranged on said planetary carrier at positions are equally spaced from said axis of rotation of said planetary carrier and are rotatable around its own axis of rotation relative to said carrier; and a turntable having three eccentric pins equally spaced from its axis of rotation, wherein said three eccentric pins of said turntable form three revolute joints with said three eccentric holes of said three planet shafts respectively.
