A gear-lever mechanism using meshing and pushing for rotation, comprising:
- a shell, an input device, an output device, and a positioning device housed by the shell,
- wherein the input device comprises at least one driving gear rotatably provided;
- the output device comprises at least one supporting frame in which several supporting shafts are disposed to support at least one movably rotatable driven gear set;
- the positioning device comprises at least one fixed bearing gear configured to form a rotational bearing point during rotation of the output device and be fixed by the shell;
- the driven gear set comprises a transfer-layer gear and at least one idler gear;
- the transfer-layer gear comprises an upper transfer-layer gear part and a lower transfer-layer gear part, a total tooth number of the upper transfer-layer gear part and one of the at least one driving gear is M, a total tooth number of the lower transfer-layer gear part and the fixed bearing gear is N, and M and N are configured to be unequal;
- the at least one idler gear or the transfer-layer gear meshed with the fixed bearing gear is configured to rotate in a direction same with the supporting frame at a speed higher than a rotation speed of the at least one driving gear;
- the driving gear is meshed with the upper transfer-layer gear part directly or through the at least one idler gear, and the lower transfer-layer gear part is meshed with the fixed bearing gear directly or through the idler gear, such that the driven gear set is able to perform planetary meshing-pushing rotation around the fixed bearing gear under driving by the driving gear, and to drive, through the supporting shafts, the supporting frame to rotate at the speed higher than the rotation speed of the at least one driving gear;
- a meshing point between the driving gear and the transfer-layer gear or each of the at least one idler gear is set as a driving point, a meshing point between the idler gear or the transfer-layer gear and the fixed bearing gear is set as a bearing point, and an intersection point formed by the supporting frame and the axial center of the outmost supporting shaft is set as an output force point;
- and
- an axial center of the supporting shaft of each of driven gears in the driven gear set of the output device is a sub-bearing point, wherein each of the driven gears is meshed with the adjacent driven gears to respectively form two meshing points, the bearing point and the two meshing points form a triangular pushing area, and at least two triangular pushing areas connected from head to tail form a meshing-pushing-lever-type torsion output path from the driving gear to the fixed bearing gear for connection in a bent form and driving.
