Variator
Encyclopedia
A variator is a device that can change its parameters, or can change parameters of other devices.
Often a variator is a mechanical power transmission
device that can change its gear ratio
continuously (rather than in steps).

Power transmission
Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work.Power is defined formally as units of energy per unit time...
device that can change its gear ratio
Gear ratio
The gear ratio of a gear train is the ratio of the angular velocity of the input gear to the angular velocity of the output gear, also known as the speed ratio of the gear train. The gear ratio can be computed directly from the numbers of teeth of the various gears that engage to form the gear...

This contrasts with other mechanical transmissions that offer a fixed number of gear ratios...
