WIPO Patent Application WO/2021/179134
Kind Code:
A1
Abstract:
Disclosed is a transmission device, comprising: an outer rotating wheel (3); an inner rotating wheel (1), wherein the rotation axis (P1) of the inner rotating wheel (1) and the rotation axis (P2) of the outer rotating wheel (3) are parallel and not coaxial; and a plurality of meshing members (5), which are distributed in the circumferential direction of the inner rotating wheel (1) or the outer rotating wheel (3). One of the outer rotating wheel (3) and the inner rotating wheel (1) is provided with a plurality of sliding grooves (7), the plurality of sliding grooves (7) correspond to the plurality of meshing members (5) on a one-to-one basis, and the other rotating wheel is provided with fixed meshing teeth (8), which mesh with the meshing members (5); and each meshing member (5) can slide along the corresponding sliding groove (7), and if the meshing member (5) slides from a first end of the sliding groove (7) towards a second end of same, the distance from the meshing member (5) to the rotation axis (P1) of the inner rotating wheel (1) is gradually reduced.
