Title:
INTERNALLY MESHING PLANETARY GEAR DEVICE, JOINT DEVICE FOR ROBOT, MAINTENANCE METHOD, AND MANUFACTURING METHOD FOR INTERNALLY MESHING PLANETARY GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/227558
Kind Code:
A1
Abstract:
An internally meshing planetary gear device (1, 1A), a joint device (200) for a robot, a maintenance method, and a manufacturing method for the internally meshing planetary gear device (1, 1A). The internally meshing planetary gear device (1, 1A) comprises a bearing member (6, 6A), an internally toothed gear (2), a planetary gear (3), a plurality of inner pins (4), and a path (Sp1) for inner pins. The plurality of inner pins (4) are configured on an inner side of an inner ring (61) as viewed from a direction parallel to a rotation axis (Ax1), and when in a state of being respectively inserted into a plurality of inner pin holes (32) formed in the planetary gear (3), same revolve in the inner pin holes (32) and also rotate relatively with respect to the internally toothed gear (2). The path (Sp1) for inner pins is located, with respect to the plurality of inner pins (4), on at least one side in the direction parallel to the rotation axis (Ax1), and each inner pin (4) of the plurality of inner pins (4) can be removed under a state in which the bearing member (6, 6A), the internally toothed gear (2) and the planetary gear (3) are combined.
