Disclosed is a mechanically operational structure for a continuously variable transmission, the structure comprising a central shaft (1), wherein a toothed groove section (8) is circumferentially arranged in the middle of the outside face of the central shaft (1); a shaft sleeve (9) is matched with the outside face of the central shaft (1); several axial limiting grooves (10) are provided on the outside face of the shaft sleeve (9); a connecting plate (6) is embedded into each axial limiting groove (10); an arc-shaped toothed wheel section (7) is arranged on the inner end face of each connecting plate (6); each of the arc-shaped toothed wheel sections (7) and the toothed groove section (8) are meshed with each other; a pivot (11) is arranged on a side face of each connecting plate (6); and each connecting plate (6)is respectively hinged to a groove wall of each axial limiting groove (10) via each pivot (11). The mechanically operational structure for the continuously variable transmission solves the problems existing in the prior art of continuously variable transmission of easily damaged structural steel belt, complex structure and inconvenience of maintenance. |
