PURPOSE:To suppress vibration and noise by setting the speed change ratio at an arbitrary value by pressing the outer periphery of a planetary ring installed in eccentricity with respect to a sun ring onto the inner periphery of the sun ring. CONSTITUTION:An input shaft 27 and an output shaft 22 are arranged on the center of a sun ring 12, and the outer periphery of a planetary ring 14 installed in eccentricity with respect to the sun ring 12 is pressed onto the inner periphery of the sun ring 12, and the input shaft 27 revolves in alignment with the revolution of the planetary ring 14, and the output shaft 22 revolves in alignment with the rotation of the planetary ring 14. Therefore, a tooth is removed from the contact position between the planetary ring 14 and the sun ring 12, and backlash is eliminated, and the generation of vibration and noise is reduced. Further, the speed change ratio can be set at an arbitrary value by properly selecting each diameter of the planetary ring 14 and the sun ring 12. |
