| 摘要 |
The present invention relates to an automatically operating gear mechanism, wherein varying speed ratios between a driving shaft (1) and a driven shaft (2) are obtained via a rotor (3) which is rotated by the driving shaft (1) about an axis of rotation (4) and which has weights (5) that are excentrically mounted relative to axes of rotation (6) about which they are provided to rotate, whereby said weights (5), by the rotation of the rotor (3), circle about the axis of rotation (4) of the rotor (3) and whereby the rotational movements of the weights (5) about their axes of rotation (6) are transmitted to the driven shaft (2) via a toothed transmission gear (7). For e.g. eliminating substantial effect limitations in such a gear mechanism or device, the axis of rotation (6) about which each weight (5) rotates, extends at a right angle ( alpha ) or at a substantially right angle ( alpha ) relative to the axis of rotation (4) of the rotor (3), whereby the mass of the weights (5) twice per revolution is diposed farther away from the axis of rotation (4) of the rotor (3) than otherwise, so that the force generated by the rotation of the weights (5) culminates twice per revolution. |
