Document Type and Number:
Japanese Patent JP2018059556
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cycloid speed reducer capable of reducing backlash between a planetary gear and an internal gear, and reducing backlash between a P-shaft and the planetary gear.SOLUTION: In a cycloid speed reducer including an eccentric body, a planetary gear, an internal gear and P-shafts, the plurality of P-shafts are connected to an output shaft through a supporting body, the plurality of planetary gears are arranged in row in an input/output shaft direction, both of gears adjacent in the input/output shaft direction of the plurality of planetary gears have substantially rectangular through holes extended in a tangential direction of a concentric circle outside of a center round hole, one of the adjacent gears includes a first connecting portion, the other of the adjacent gears includes a second connecting portion, the first connecting portion and the second connecting portion are connected through energization means, and the adjacent gears are energized in a reverse rotation direction in a manner of holding the internal gear.SELECTED DRAWING: Figure 1
