Abstract

A gear arrangement 10 which comprises a first disc member 12 rotatable about a first axis 14 and carrying rings 16 of teeth 18, the rings 16 being centered on the axis 14 and at respective distances therefrom. A second member 20 is rotatable about a second axis 22 and carries further teeth 24. The second member can move toward and away from the first axis 14. The teeth 18, 24 are so formed as to allow the second teeth 24 to mesh in driving manner with each ring of teeth 18 as the second member 20 moves toward and away from the first axis 14. In this way, the transmission ratio of the gear arrangement can be changed.
