<p>A variable ratio gearbox including a centre shaft (1), cage (6) and outer body (5). A first member (3) is between the centre shaft (1) and the cage (6) for communicating movement therebetween, and a second member (7) is between the cage (6) and the outer body (5) for communicating movement therebetween. Upon rotation of one said component (shaft, cage or outer body) at least one of the remaining components is caused to rotate. The output from one component (shaft, cage or outer body) is such that variation of a load between zero and a maximum value corresponds to variation of the ratio of the angular velocity between the other two or more components. This variation is achieved by a second input or brake (10).</p> |
