Title:
INTERNAL MESHING PLANETARY GEAR APPARATUS AND ROBOT JOINT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/002388
Kind Code:
A1
Abstract:
An internal meshing planetary gear apparatus and a robot joint apparatus. Although the structure is relatively simple, axial movement of a crankshaft can be limited. The internal meshing planetary gear apparatus (1B) is provided with an internal gear (2), a planetary gear (3), an input-side gear carrier (18), an output-side gear carrier (19), and a limiting structure (9). A crankshaft (7A) rotates around an axis to swing the planetary gear (3). The input-side gear carrier (18) and the output-side gear carrier (19) are arranged on two sides of the planetary gear (3) along the axial direction of the axis, and rotatably support the crankshaft (7A). The limiting structure (9) only limits the movement of the crankshaft (7A) towards the two sides on the axial direction at any one gear carrier among the input-side gear carrier (18) and the output-side gear carrier (19).
