  • Toothed wheel with a variable number of teeth
    Patent number: 5406863
    Abstract: A toothed wheel with a variable number of teeth has a toothed ring formed by a driving chain or belt. The referenced diameter of the toothed wheel can be modified by adding or removing individual links by means of an auxiliary toothed wheel; so as to modify the length of the drive chain. At least one transmission member cooperates with the toothed wheel to insure the transmission of energy. The auxiliary toothed wheel is displaced together with the lateral guide of the driving chain, so that its radial spacing from the axis of rotation changes synchronically with the radial spacing change of the lateral guide of the driving chain.
