The Evans friction cone, a type of cone ring transmission. Moving the friction ring between the two cones varies the effective gear ratio
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).
