Title:
バックラッシュレス遊星歯車装置
Document Type and Number:
Japanese Patent JP7041818
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a planetary gear device having a small backlash amount.SOLUTION: For a mechanism configured to impart inlet rotation to a carrier, engage two-stage planetary gears 3a, 3b with a stationary gear 4 and an output gear 5, and increase/decrease speed, planetary gears satisfying the following states coexist in fixation of the carrier to remove backlash: the state that a clockwise side dead point planetary gear contacts with a counterclockwise side surface 17 of the stationary gear and a clockwise side surface 16 of the output gear; and the state that a counterclockwise side dead point planetary gear contacts with a clockwise side surface of the stationary gear and a counterclockwise side surface of the output gear.SELECTED DRAWING: Figure 1
